Fruit Crops


Why doesn't my apple tree set fruit?

There are three apple varieties recommended for Florida: Anna, Ein Shemer, and Golden Dorsett. Most apples are not self-fruitful; for example, when Anna is planted alone, it will not bear fruit. It is recommended that Anna and Golden Dorsett be planted together because they bloom at the same time and cross-pollination will occur. Ein Shemer is self-fruitful. You may have a more northern cultivar, which is not receiving enough chilling hours.


What pecan variety can I grow here?

The three pecans recommended for Central Florida are Curtis, Mooreland, and Desirable. However, these are recommended as shade trees and should not be expected to produce quality pecans. There are several diseases that have significant effect on the yield and the quality of the nuts. These diseases are more expensive to control than it would be to purchase the pecans.


What plum variety can I grow here?

There are no plum varieties for Central Florida. - Plum and other Pit or stone fruits require a certain number of chilling hours in order to get blooms and subsequent fruit production. The chilling hours required for plums is higher than for some of the other stone fruits like peach and nectarines, which can grow here.


Why aren't my blueberries growing well?

Most likely your pH is too high. Blueberries like very acid soil - between 4.5 and 5.5. Most of the soil in our area is not naturally this acid, but we can acidify the soil by fertilizing with an azalea/camellia fertilizer or ammonium sulfate.


How do I fertilize citrus?

Citrus is to be fertilized three times per year: February or March, May or June, and October or November at the rate of one pound per year of the tree's age with a maximum of thirty pounds per year application.

A 6-6-6 or 4-6-8 citrus special with minor elements or trace elements would be the recommended analysis. Apply the fertilizer to the entire rooting area, which extends from the trunk out to several feet beyond the drip line of the tree. See the article on"Plant Nutrients and Fertilizers" in the "Home Citrus Handbook".


Why are my citrus fruits splitting? What can I do about it?

 The fruits are splitting because of water stress. Too much water in the later stages of fruit maturation will cause the flesh to expand beyond the capacity of the rind. Hamlin and Valencia and young trees are more prone to splitting than other varieties and older trees. To lessen this as much as possible, it is important to water citrus when adequate rainfall is lacking and fertilize as recommended to produce a tougher rind. See the article on "Plant Nutrients and Fertilizers" in the "Home Citrus Handbook".


I get lots of citrus bloom but relatively few fruit. What is the problem?

Citrus must be planted 3-4 years before it can reach a stage mature enough to set fruit. It may bloom prolifically, but until it is mature and established, it will drop its blooms. Also, citrus generally only sets 1 to 2 percent of the total bloom.


Should I mulch around citrus?

Mulching is an excellent practice for most plants, but not for citrus. Citrus is very susceptible to a disease called foot rot which causes peeling bark at the soil surface and root rot. Mulching citrus encourages this disease.


The leaves on my fig tree turn spotty brown and drop. What is the problem?

Fig rust is a very common disease on figs. The rusty foliage that drops should always be raked up and disposed of since the spores on the fallen leaves can infect new unaffected leaves on the tree. There are no EPA approved fungicides for figs grown in Florida.


I have an avocado tree that I planted from seed 12 years ago. It froze several times and has never produced fruit. What should I do?

Avocado trees are quite variable as to hardiness and the time it takes to produce fruit. Most fruit within 5 to 7 years if they are not affected by a freeze. You have to hope for a series of warm winters to see your first fruit.

Perhaps it might be better to grow a more cold-tolerant avocado tree. Some varieties that survive light freezes include Brogdon, Gainesville, Lula, Mexicola, Taylor, Tonnage and Winter Mexican.


My nectarine tree is starting to lose its leaves, and there is no new growth. What is the problem?

Many nectarine trees are running out of fertilizer, which is evident by yellowing leaves that gradually drop. Some are also affected by a leaf spot fungus that hastens the loss. It is best if the trees keep their foliage another month to prevent early flowering during late fall and early winter.

Help the nectarines and peaches hold their leaves a little longer by feeding lightly. If leaf spotting is severe,a fungicide labeled for deciduous fruit tree use could be applied. Also make sure the trees have adequate water during the often dry fall and winter months.


When is our stalk of bananas going to ripen? The fruit started forming at the beginning of summer.

Bananas begin to ripen about five months after the first hand appears on the stalk. Wait until it starts to turn yellow. Then harvest the stalk and hang it in a shady spot to continue ripening. In a week they should be yellow and can be removed.


I planted a Meyer lemon last year that I was told is an ever-bearing tree. When can we expect the tree to start fruiting?

You are going to be a little disappointed but not totally unhappy with the Meyer lemon. First, it bears fruit that taste like lemons but look more like oranges. It's not a true lemon, but it makes great lemonade, pies and other pastries. The Meyer is hardier than the true lemon, so it might be better adapted to local landscapes.

Meyer lemon trees mature their fruits November through March. That's hardly ever-bearing, but it's enough time for you to get plenty of fresh lemonade and to store juice for the future. Also; it's not a tree but more of a large shrub. It's probably just the right size for most home landscapes, so you have room for other plantings too.


I have a potted fig tree that has stopped giving fruit and has lost its leaves. Should we prune it for winter?

It's best to allow the fig tree to remain dormant for the first few months of winter. Do needed pruning during mid to late February just before the plant begins new growth. Pruning too soon may encourage shoots and foliage that could be affected by cold.


A year ago I started a grapefruit tree from seed, and it has grown to more than two feet tall. When can I add it to the landscape?

Wait until winter is over, and then plant it in a sunny location with plenty of room to grow. Citrus trees grown from seed tend to be larger and thornier than grafted trees. Also they can take 8 to 9 years before producing the first fruit. Care for your tree normally for good growth.


We have just returned from vacation and found our Honeybell citrus branches touching the ground and full of fruit. Can I use boards to brace the limbs to keep them from splitting?

Honeybells, also known as Minneola tangelos, are reaching their mature size, but harvesting does not begin until December.

You could lighten the load by picking off some of the fruit, or trimming the limbs, but most gardeners won't think of giving up these tasty fruit. Your suggestion of some well-placed notched boards to prop up the overloaded limbs is probably the best one.


We want to plant orange, lemon, grapefruit, and tangerine trees. Should we wait until spring, or is December-January OK?

Gardeners add new citrus trees to the landscape year-round. Winter is a good time because the trees can become established and be ready to produce new shoots and leaves when warmer weather arrives.

When planting during the coldest time of the year, there is the potential for frost or freeze damage. But because new trees are small, only minimal effort would be needed to provide cold protection. A large box or even a trash can set over the new tree may be all that is needed to prevent major damage.


We started an avocado tree from the pit, and now it stands more than 8 feet, so covering it is impossible. Last year we lost more than 3 feet oft the top to the freeze. What is the best way to protect it from the cold?

Trees grown from saved seeds are often susceptible to cold. Many are injured when temperatures dip to just below freezing. The only practical freeze protection is to plant the tree in the warmest portion of the landscape, where temperatures might not reach the lower damaging levels. Every other form of protection involves entrapping or supplying heat.

You noted covering was not possible, but it's the only way to ensure protection from the cold. Some gardeners have kept their trees small, about 12 feet, and developed supports using poles that can be fitted with a plastic cover to protect the trees during cold weather. On the very cold nights, they have then added light bulbs to provide warmth. If your tree should be lost to cold, consider planting a more freeze-resistant avocado variety.


My bananas are fruiting, but all I get are a few hands of fruits, and the rest fall off. What can I do to get more bananas?

Home-grown bananas are notoriously sparse bearers, but much of the problem is cultural. Often, gardeners don't get enthused about this crop until they see the first hands of fruits forming, and then they start the good care programs too late.

Bananas need good care from the time the plants are set in the ground. Keep the soil moist, and maintain a 4-inch or more layer of mulch. Also feed the plants monthly with a light scattering of a general garden fertilizer March through November.

With this care program, you should be able to double production, but not every fruit that begins to form remains on the stem. After several hands of fruits begin to swell into bananas, sterile fruits start forming and drop from the bunch. The plump banana bud is usually still flowering when the first-to-form fruits ripen and the stalk is harvested.


A limb on my papaya tree broke while bearing several large fruit. Will they ripen off the plant? What can I do to support other limbs that have grown out of an old trunk?

Shoots sprouting out of an old trunk are weakly attached and often beak off when maturing their fruit or if blown about during storms. The only good control is to tie the limbs to a stake for support or remove some fruit to lighten the load. The fruit from fallen limbs may turn ripe light green to orange color, but they likely will not have the desired taste.


We have a young orange tree, and the leaves are turning black. What is causing this discoloration?

Look beyond the discoloration for piercing, sucking insects that are causing the discoloration. Often aphids, whiteflies and scale insects are feeding on the undersides of leaves and along stems and producing excreta that falls on the leaves. A sooty mold fungus then lives on the nutrient-rich excreta to produce the unsightly leaves.

Some insect activity and sooty mold growth can usually be ignored, usually on older trees. If the insect activity and sooty mold coatings are slowing the growth of young trees, an oil spray available from your garden center can be used to treat the pests. The oil spray controls the insects and causes the sooty mold to slough off over a period of several weeks.


We planted an orange tree that is now 5 years old and about 4 feet tall. It starts to produce fruit that fall off when young. It gets adequate water and fertilizer when the lawn is fed. What should I do to help the tree hold its fruit?

Your tree may be 5 years old, but it's mighty small to be holding a crop. Most early bearing trees are in the 6- to 8-foot range. Try a different feeding schedule than is provided for lawns to increase growth. University of Florida recommendations suggest feedings once monthly in March, May, August and early October.

Calculate the needed citrus fertilizer by measuring the circumference of the tree 6 inches above the ground. Weigh out ¼ lb of the fertilizer for each inch of tree circumference and scatter it under the spread of the tree and out past the drip line. Then apply about a ½ inch of water to move the nutrients into the root zone.


Our edible fig is producing fruit. What fertilizer should we use to encourage the crop?

Figs are not heavy feeders, but they like a light and steady nutrient supply. Many gardeners feed their figs with manures applied every other month March through September. Just a thin layer over the surface of the root zone is adequate. Maintain a 4 - 6 inch layer of mulch under the plants that also supplies some nutrients as it decomposes. Also keep the soil moist.

If you wish, a general garden fertilizer can be substituted for the manure. Light applications are usually made every 6 to 8 weeks, spring through late fall.


I have a thriving Ohio raspberry plant that won't form blooms. What does it need to produce flowers and berries?

If it gets cool enough to encourage good flowering and fruiting of your raspberry plants, most Florida residents are going to be unhappy. The northern raspberries need a cold winter to mature their buds and bloom the following spring. Many of the varieties do produce lots of green foliage but are a disappointment locally when it comes to fruit production.


My citrus tree is only 2 years old, and it has not produced fruit, but it has a defect in the leaves. They are curling and there appears to be lines on the surface. Would you help?

Leaf miners don't care about the age of the trees and often seem to affect young trees, more so than older trees. This is a common pest that tunnels in the leaves, producing the trails and curling of the foliage. It is usually tolerated by gardeners with older trees, and the insects don't seem to affect the production significantly.

Because your tree is only 2 years old, and the leaves are important to the establishment of a good producing tree, you may want to apply a control. Gardeners can apply an oil spray available from the garden center, but proper timing of the spray is important. It has to be applied when the new leaves are less than an inch long. Also a repeat treatment is needed in 10 to 14 days. Even when a spray is applied, some leaf-miner damage is usually noted and has to be tolerated.


I have a small Meyer lemon tree that was planted about a month ago. Last week the leaves started to turn yellow. Is this a water problem?

Summer rains have saturated local soils, and unless your planting site has good drainage, the tree could be flooded. Better dig down near the tree to look for standing water. If the hole fills with water or the soil is extremely wet, you have a drainage problem that needs to be corrected or the tree should be moved to a better drained site.

Because this is a young tree, make sure the root ball has not dried and become hard to wet. Once a tree dries, the organic matter in the root ball often repels moisture. Water you apply or water from rainfall often runs around the outside of the root ball and the plant remains dry.

If the plant is dry, build a 4 to 6inch berm of soil at the edge of the root ball to direct the water through the root zone to moisten the tree.


I have several container-grown pineapple plants that are producing fruit that are leaning to one side. How can I prevent them from falling over, and what should I do with suckers forming along the stems?

You should harvest juicy sweet pineapples in a month or two if you give the plants a little support. Push a stake into the pots, and then tie up the fruiting stems. Some varieties are more inclined to lean than others, and if not held in an upright position, the fruits may get sun scald.

Leave the suckers along the stems until you harvest the fruits. Then trim the shoots to start more plants. Cut the shoot next to the stem and push the base into a container of fresh potting soil to root and grow a new pineapple plant.


A lemon tree planted about three years ago has developed a long shoot at the top and new branches from the base that make it look off balance. Should I leave the shoots on or take them off?

The irregular growths may make the tree look funny, but they should have no effect on longevity or future fruit production. Perhaps you would feel better if the tree were reshaped to conform to the landscape. It won't hurt to trim back the ends of the branches or to remove them if the tree will look better.


We have a tree full of grapefruits that are starting to ripen but are quite small. Will picking some help the ones we leave to grow bigger?

This year the fruits are going to be small but most likely tasty. Once the citrus starts to ripen, they have reached maturity and their full size. Thinning the trees is usually not practiced to control fruit size, because the trees often drop portions of the crop during the growing season to help regulate the size. If you wanted to remove some of the fruits to increase the size of others and lighten the load on the limbs to prevent breakage, the best time would be during spring as the new crop begins to enlarge.


A few months ago, I planted a papaya in a pot and planned to bring it indoors during the cold weather and then plant it outdoors during spring. I tried to move the plant the other day, and the roots have grown into the ground. What should I do?

 Cold weather could cause much more damage to this plant than trimming off a few roots. It won't be too much of a shock to cut the roots where they emerge from the container. Do keep the soil moist as your plant has been getting some of its water and nutrients from outside the pot. You might consider giving it an inch or two larger container for a few months. Then your plant should be ready for its new home next spring.


A friend gave me a wonderful tangerine. Is there a way I can sow the seeds and start a tree?

Citrus trees are easy to start from seeds, but it could be a long wait for the first fruits, plus you are not sure what you are going to get as a new tree. Usually, 75% of the seeds that sprout and grow a tree produce fruit just like the one you enjoyed. The others may produce fruits similar but different in color, size or taste.

Trees from seed are also usually larger thah the parent that produced your fruit, thornier and take up to nine years to yield the first harvest. Wouldn't it be easier to plant a Sunburst or Dancy tangerine, which also has a wonderful sweet taste?


A friend has a papaya tree that is full of fruits. How does she know when they are ready to pick?

Squeeze the first fruits that formed to determine when they are ready to eat. Papayas have the best flavor when they go from firm to soft. The dark-green color also lightens, and the fruits might turn yellow to orange.

It's best to wait until all signs are present; fruits picked too soon will have a bland taste. Many think the varieties that turn a deep-orange color are the sweetest tasting.


I live in Kissimmee and would like to plant a lemon tree. What type should I choose, and what soil and fertilizer does it need?

You are not living in lemon country, but many gardeners try to grow lemons. Lemons need a warm location where the temperatures stay above the freezing point. But if you are willing to huddle around your tree on a cold night, you may be successful.

Perhaps the best answer is to grow the tree in a large container that could be moved to a freeze-proof location during cold weather or grow it in the warmest spot available in your landscape. Some varieties you would like include Bearss, Eureka, Lisbon and Villafranca. You also could grow the Meyer lemon that resembles an orange but has the lemon taste and appears to be at little hardier.

Lemons grow in full sun and any sandy, well-drained soil. In-ground plantings should be fed once monthly in March, May, August and early Qctober using a citrus fertilizer. Feed container plantings monthly March through November with a soluble 20-20-20 or use a slow-release product fertilizer following label recommendations.


I would like to add another citrus tree to our landscape. Can you tell me the name of the large, sweet, seedless tangerine with a peel that practically falls off when you peel it?

Perhaps you remember during the holiday season Santa used to bring good boys and, girls a tangerine. That was the easy-to-peel Dancy tangerine that ripened conveniently during December. But now there is another tangerine called Sunburst that has become popular with producers and home gardeners. It begins ripening during November, has a bright orange color and a sweet taste.

Even though Sunburst is now the No.1 tangerine, either variety would be a good selection for the new planting.


I am growing a pineapple in a container, but the plant has started looking yellow. What does it need?

Perhaps warmer weather and fertilizer would improve your plant. Cooler temperatures can cause the pineapple plant to turn yellow. If the temperatures dip to freezing, the plants can be severely damaged, turn brown and die. Luckily, your plant is in a container and can be moved indoors to prevent this injury.

Plants in containers should receive a fertilizer application at least monthly during the cooler weather and every other week during the warmer months.
Use a 20-20-20 or similar fertilizer at the label rate to make a solution that can be used to wet the soil during a normal watering. This extra care should help regreen your pineapple plant by spring.


We would like to add a few new citrus trees. When is the best time to plant a tree?

Spring is an ideal time to plant new citrus trees. Garden centers have a good supply to pick from, and the trees are ready to begin root and shoot growth. Make sure you give the new tree a sunny site and space the trees at least 12 to 15 feet apart. If you miss the spring planting season, don't worry. Container-grown trees are available year-round. They can be added to the landscape anytime.


Last year we purchased a home with an old orange tree. How much pruning does it need, and when should it be fertilized?

The main care needed is regular feedings with a citrus-type fertilizer in March, May, August and early October.

Use one-quarter pound of the citrus fertilizer for each inch of tree circumference measured 6 inches above the ground. Then scatter the fertilizer over the surface of the soil under the spread of the tree and beyond the drip line.

Pruning usually is restricted to the removal of declining branches and limbs that might be in the way of tree maintenance. Also remove any shoots that begin to form below the graft that is normally found within a foot of the ground.


Our avocado trees have produced several fruit this year that appear to be the right size to eat but are hard as a rock. When is the best time to pick them?

Avocado fruit do not ripen on the tree even though they may be mature and ready to harvest. they soften after they fall to the ground or you pick them and let them ripen in the home. If you know the variety, then you can look up the general ripening period using guides available from your local University of Florida Extension office.

Because your fruit appear to be the right size, harvest one or two and allow them to soften in the home for a few days; then taste them. If the flavor is good, your fruit is ripe for picking. If not, wait a few weeks and try again.

Usually the fruit can be harvested over a period of a month or two once they begin to ripen. Mark the month of ripening on your calendar so you can harvest the fruit on time in the future.


I am interested in obtaining an avocado tree for my yard. What varieties grow best in Central Florida?

Select your avocado tree for cold hardiness. Varieties that grow well locally include Brogdon, Gainesville, Lula, Mexicola, Taylor, Tonnage and Winter Mexican. These can survive temperatures that dip into the 20s without significant damage to the trees.


My wife has grown an avocado tree from a seed. The tree is about 4½ feet tall, and we want to transplant it outside. Where is the best location, and how cold-hardy is the plant?

Avocados need the full sun and lots of room to grow to a mature size of 40 feet tall and about as wide. You can keep the trees trimmed to a height and width of about 20 feet. The problem is cold hardiness.

Most avocado trees grown from seed are sensitive to temperatures in the upper 20s. Usually the trees survive in local landscapes, but they lose flower buds and small limbs after a night or two of temperatures below freezing. Give your tree the warmest spot in the landscape, and it should begin fruiting after four to five years of freeze-free weather.


An avocado tree I raised from seed is about 10 feet tall but has not produced fruit. I have been told to cut around the trunk to make it bear fruit, but this sounds absurd to me. What should I do?

As unreasonable as it might sound, ringing trees and vines has been used to encourage fruiting, but it also makes wounds that might become infected. The idea is to prevent foods manufactured by the leaves from moving down the trunk to the roots. In some cases this seems to fool the plants into thinking they are ready to begin fruit production.

Ringing or other trunk-damaging techniques are usually not used in home fruit production and might be risky if you have only one tree. Perhaps it's better to wait a year or two more until your tree is mature enougt to bear fruits on its own without the trickery.


Many of my navel citrus fruits are dropping from the tree. When I pick them up, they have small holes in the skin, and little brown insects come out from inside the fruits. What should I do?

Navel trees are not the best producers, but they grow the fruit gardeners want the most. The trees drop and split a lot of fruits during the fall. They also often produce dry, grainy fruits, especially when the trees are young. So why not an insect problem, too?

The insects are secondary. They are called sour bugs and enter fruits starting to decline. Usually these are the ones about to drop or that already have fallen to the ground. Those little brown beetles are trying to help remove the debris. They are too numerous and impossible to control with pesticides.

Pick up the fruits as they fall and discard them to reduce the bug activity. Even with all these problems, there should be plenty of good navels left to ripen normally and enjoy.


I have a small lime tree that has never been trimmed. Does it need pruning, and, if so, when should it be done?

Citrus trees of all types need little pruning. Some grooming could be done at about anytime. This might include the removal of limbs growing outside the normal spread of the tree, branches that have become entangled or shoots growing from below the graft. Seldom do citrus trees need extensive pruning, but if you want to reduce height and width, it is best performed in mid-February just before spring growth begins.


We moved to a home with a grapefruit tree, and it's loaded with fruits. How will we know when they are ready to eat?

Lucky you. Grapefruits are expensive at the stores. Deciding when the fruits are ready to eat is quite simple. When they taste good, they are ready to pick. Some Floridians wouldn't consider eating a grapefruit until March when they get super sweet, but not all residents are so particular.

Most start sampling the fruits around November and add a little sugar, if needed, to take away the tart taste. As the season progresses, less sugar is needed because the fruits only improve in flavor.

Grapefruit can be left on the tree for many months, and if any remain as late as May or June, they are still sweet, juicy and edible.


What fruits were used to produce a tangelo? I say it's a grapefruit and an orange.

 Don't bet on this combination, or it's going to leave a sour taste. Crosses that produced the first tangelos began during 1892 at a U.S. Department of Agricu1ture field station in Eustis by combining grapefruit and mandarin-type fruits.

Some of the more popular tangelos resulted from crosses made during 1911 between a Duncan grapefruit and the Dancy tangerine, a type of mandarin. Two fruits from these pairings that are still favorites with home gardeners are the Orlando and Minneola tangelos. The latter also is known as the Honeybell.


I have chips from a tree stump that I had removed from my yard. I would like to use them to mulch around the base of my grapefruit tree. Would this help control the weeds?

Certainly the mulch should help with weed control, but it also might create conditions unfavorable for the grapefruit tree. It's best to keep mulches, grass and ornamental plantings several feet away from the trunks of citrus trees. The extra moisture maintained within the mulch encourages a disease called footroot that causes the trunks to decline.

Perhaps the best advice is to add the chips to a compost pile or scatter them lightly over other previously mulched areas. Fresh wood chips bind up nutrients as they decompose and make it hard to know how much fertilizer to use when feeding plants in the mulched areas. If the chips are added to a compost pile, they can decompose and be ready as a nutrient-rich soil additive in about four to five months.


I have several ficus trees in containers, with leaves that have remained closed and are turning yellow. Tiny insects appear to be inside the leaves. What should I do?

Thrips, those tiny insects inside the leaves, appear to be calling many plants home. If they are not feeding in buds or flowers, they are sucking the juices from leaves. The hairsize white to black stages found on the ficus have been in local landscapes for about two years. Control can consist of a natural oil spray if you can hit the pests. That's hard to do with the insects clustering,inside the folded leaves. Many gardeners have resorted to the more residual synthetic pyrethroids found at garden centers to catch the thrips when they come out in search of new feeding sites.


I have a citrus tree that was producing fruit when purchased but the next year did not even bear a flower. I thought it might be in the wrong place, so I moved it, and two yeats later it's growing fine but still no flowers or fruits. What should I do?

Your tree appears to be getting a tour of the yard and probably some pretty good care, too, so why should it bother to flower or fruit? It's not abnormal for trees to have a few fruits the year they are planted and then take time off to make good growth. In fact, these trees might take three to five years to come back into production.

Give your tree some time to grow, become mature and get into the production mode. The move most likely slowed the tree a little, but in a year or two, you should see some flowers and fruits. Until then, give it good care by watering when the soil starts to dry and feeding lightly in March, May, August and early October.


We planted two orange trees a week ago. How often do I fertilize the trees, and when do we begin spraying?We planted two orange trees a week ago. How often do I fertilize the trees, and when do we begin spraying?

Wait a few more weekS before giving the trees their first feedings. Usually the trees come with adequate fertilizer to supply the nutrients they need for about a month. Then you can begin light feedings with a citrus fertilizer once every six to eight weeks.

Start with about a half-pound of fertilizer scattered under the trees and gradually increase the rate to 1 pound by early October, the last feeding of the year.

Most citrus trees do not need a spray program. Some leaf blemishes usually can be tolerated. One of the worst problems with new trees is leaf miners that cause the leaves to be marked with white lines and to be contorted. Still, the trees seem to grow just fine.

If needed, an oil spray or the natural insecticide 'Conserve' can be used as a control following label instructions. When other problems. appear, it's best to have them checked at your local Extension office, and then apply a control if needed.
