Cashew Nut tricks and challenges

Q: I bought a cashew plant in May of this year it has been slow-growing well then all of a sudden it started dying. I have cut it back halfway down. So a plant that was close to 3 ft tall is now 1 1/2 feet. I see new leaves trying to spring closer to the root. Help! It's in a huge 18" wide pot, I have not put it in the ground yet. I am in the Orlando area.

A: Generally speaking, Cashew is not the easiest plant to grow. Cutting it down added more stress to the plant. A few thoughts:

1) Chances are, the tree was over-watered (possibly summer rains, we had pretty wet summer this year in FL). Cashew trees are very sensitive to over-watering while young. Considering it sits in pretty large pot, this may have created soggy conditions. Don't bother repotting the plant now, just try to reduce watering. We have less rains now. If you have automatic sprinklers, move it away from sprinkler so you can control moisture manually. Even better - move it under roof (lanai, etc) where it still can get lots of bright light, but you can control water.

2) In Orlando, winters are too cold for this tree. Make sure to protect it from cold - bring inside when temperature drops below 65F, especially considering that the plant is still struggling.

3) Keep in mind that Cashew is semi-deciduous tree, meaning it looses leaves during cooler period. If all leaves are gone but the stem still green (after nail scratch) - just give it time, it may start growing vigorously in Spring.

4) You may apply Sunshine Boosters with every watering (which should be once a week, or even less frequent if the soil is still moist) - SUNSHINE C-Cibus - Crop Nutrition Booster

Keep the plant in full sun or at least very bright filtered light. It must be always warm. Bring inside if below 65F.

Healthy Plants. Q&A from Mr Booster: Fertilizing Mango trees in Winter

Q: I'm living in Maryland growing zone 7A and would like some info on when to fertilize my potted mango trees. I ordered your Sunshine Mango Tango 2-2-4. All your mango trees are in pots.

A: You can start using this fertilizer right away, any time of the year, and every time you water your plants.
Sunshine Mango Tango, as well as other Sunshine boosters, is an amino-acid based liquid fertilizer that is scientifically developed for daily plant needs in all necessary nutrients. This means, you may use this fertilizer with every watering, including winter period.
Traditional fertilizers (both granulated and soluble, EDTA-chelated) can only be used during hot months while plants grow actively, and must be limited or not used at all during cooler months, to avoid nutrient lock up in soil (which basically means "building up unused elements"). With Liquid Sunshine Boosters, it is safe to add them every time you water your tree.
During cooler weather and when plant metabolism slows down, a tree will consume less water (as well as food), and you will automatically reduce watering, to keep over-wintering plants on a dry side. This means, less fertilizer too. This allows you to control elements intake naturally, like you control water amount just as much as the plant needs.

What fig trees are good for Florida?

Q: My baby fig tree was sprayed by the lawn people with weed killer :( Any ideas? Also what figs do you have available to grow here in Florida?

A: Unfortunately once a plant is affected by a herbicide, there is not much you can do about it. If you don't rinse the chemical within a few seconds, it gets into the plant internal system and nothing can be done to save the plant. The tree may remain green for a few days up to a week, but then gradually dies back. If your fig tree wasn't rinsed immediately after herbicide spray, it is probably too late.
If you want to replace it with a new one, here is a few suggestions of our favorite fig varieties which are great producers and grow well in Florida heat:

Brown Turkey Fig - our favorite!
Black Mission Fig
Beers Black Fig
Texas Everbearing Fig
Magnolia Fig
LSU Purple Fig
Olympian Fig
Texas Blue Giant Fig
See full list of Fig Trees.

Make sure to get appropriate plant food for your fig tree so it develops faster for you and gets well-established before winter: SUNSHINE C-Cibus - Crop Nutrition Booster from Garden Series, or Combo Total Feed Collection - all nutrients in just one bottle, for fruit trees and edibles.

Healthy Plant Food: Q&A from Mr Booster

Why my Sapodilla is not fruiting?

Q: I bought a Sapodilla tree from you several years ago, Silas Woods. I live in Houston area. The tree grows and produces blossoms for fruits, but then they just dry up and fall off. To-date, I have not gotten any fruits off the tree. Is there a reason for this? I really want a fruiting tree because Sapodilla is one of my favorite fruits. I have attached pictures of the tree. Please help.

A: Silas Woods is a free-flowering variety and in favorable conditions it should produce fruit almost year round, considering warm temperatures. The fact that the tree is producing flowers indicates that it is strong, overall healthy and ready for production, but for some reason these flowers don't set fruit. There may be several reasons for such behavior.

1) Too high temperature and too low humidity
In Houston area, humidity should be good in summer. However, if temperatures stay above 90F for a long time, this may cause flower dry-n-drop.
Solution: try to move the potted tree into filtered light, or in a spot where it does not get direct burning sun during the hottest hours of the day (morning sun is the best)

2) Root bound.
Solution: check if the tree needs stepping up into a larger container.

3) Lack of certain nutrients that are responsible for proper fruit formation.
In particular, elements B (Boron), Mo (Molybdenum), and a few other micro-elements (Fe - iron, Cu - Copper, etc.). This is most likely the cause of a flower drop. This is very common reason for undeveloped fruit or lack of fruit in container-grown fruit trees. When grown in the ground, plants can reach out to all necessary elements in surrounding soil (considering soils are not too poor on necessary elements). In a pot, a supply of nutrients can be exhausted very quickly, so a quality fertilizer program is very important. Fertilizer must include all necessary nutrients in easy accessible form, and a plant must have their constant supply for proper development.
Solution: prescribe to your Sapodilla tree the following combination of plant food:
- SUNSHINE C-Cibus - Crop Nutrition Booster. It will provide well-balanced amounts of high absorption Nitrogen, as well as other macro-elements - to provide enough energy to the tree, plus a combination of all necessary micro-elements. It is safe to apply this fertilizer as frequent as with every watering, including winter time.
- SUNSHINE-Honey - sugar booster. This supplement has a high content of elements Mo and B - once the tree starts getting them on regular basis (a few times a year, according to the label), it will change its habit dropping flowers and/or premature fruit drop. As extra bonus, Sunshine Honey makes fruit sweeter by bringing sugars from all over the plant and concentrating them into fruit.

4) Lack of pollinating insects.
Solution: For most effective pollination, we always recommend to put some pieces of fruit under the tree, apple peels, or even banana peel. Those attract tiny beetles that are responsible for small flower pollination.

With winter time approaching, fruiting season is about to end, however, do not get discouraged and start the fertilizing program right away: this will bring up the plant into a healthy stage within a few months, and by next season it should be covered with fruit you like so much! Remember, Sunshine liquid fertilizers can be used year round, including winter, without a risk to burn roots or overdose, as long as you follow label instructions.

Fast-fruiting trees?

Photo above: Annona reticulata - Red Custard Apple

Q: More of a question than a review, but a review regarding your catalog, it would be easier for us buyers, if we could search for plants that produce fruit in 2 years or less, I don't have the patience to wait longer than that for fruit. I'm trying to buy for a fairly good sized garden but want some fast growers and fruit produced in 2 yrs. Can you help me out?

A: Fruiting time depends on many factors (established size, growing conditions, fertilizing, and even specific variety), this is why we can not just put a simple icon "will fruit within 2 years".
However, most grafted and air-layered fruit trees, including all Mango, Avocado, Loquat, Sapote, Sapodilla, Lychee/Longan, Peaches and Nectarines - will fruit right away. If you see in our store "grafted" or "air-layered" in plant description - these trees will fruit soon. Some of them already flowering and fruiting.
Some non-grafted trees or seedlings like Annona, Artocarpus (Jackfruit), Eugenia, Guava, Banana, Dragon fruit, Mulberry, Blackberry/Raspberry - will fruit within 3-4 years from seed or even sooner (Banana, Mulberry, Dragon fruit, Blackberry-Raspberry - within a year). Usually it says in description that this plant can produce fruit soon.
Bigger size plants are more established and have more energy to produce, so try to get larger size plants if your budget permits, and especially if you can pick up bigger plants rather than shipping them - obviously, shipping has size limitations.
In addition, all spice trees like Bay Leaf, Bay Rum, Allspice and many more - they will produce spice for you right away, so you don't need to wait at all!
If you have questions about fruiting time on any specific plant you put your eye on, don't hesitate to ask!

The best Loquat varieties with big, sweet fruit

Q: I'm interested in loquat and read through the varieties you offer but wanted your recommendation. I'm looking for a variety that is big, sweet (not tart) with 1 seed. Of the varieties you offer... Which variety would you recommend?

A: From our experience, the most popular Loquat variety is Christmas. It is an early ripening type hence the name Christmas. Fruits are very large for a loquat, they are bright yellow with a tangy apricot flavor.
Another good variety we recommend is Yehuda - it has a large fruit and very small seed Also, variety Oliver for many years has been considered the best loquat for South Florida. The fruiting season is March to May. It has medium to large fruit. The fruit is very sweet with only one-two seeds.
Loquats are very cold hardy tropical fruit trees, easy to grow, drought tolerant, fast growing. Fruit is great for eating fresh or making jam.

How to make Mango tree fruit

Q: Hello, I have a five-year-old Lemon Meringue tree that has only given me fruit one year. It put out about 50 mangoes and has done nothing for the past three years. Do you recommend any vitamins or any of the nutrients that you guys sell to help with this for next season?

A: We've had very similar problem with our Nam Doc Mai Mango tree, fruited once and no more next year. Usually the reason is nutrients deficiency, here in Florida we have poor soils. We applied Mango-Tango tree booster and it started flowering within a couple of weeks.
Generally, Mango flowering season is over by now, however, we recommend to feed the tree starting now, during active growth season. This way it will get better established before winter and also will store away all elements necessary for triggering flowering and fruiting. So by late Fall through Winter it will be ready to flower.
Along with the fertilizer, additional micro-element supplements will be beneficial. For improving fruit quality and increasing number of flowers, we also recommend to use SUNSHINE-Honey - sugar booster

Establishing Avocado Tree

Q: I received my avocado Wurtz tree yesterday. Per instructions I have put the tree in a pot first. However I am having difficulty deciding what to trim off. Yesterday I removed obvious damaged leaves. However as you can see, the leaves are lighter in some areas and contain yellow and red in some spots. What would you advise? Given this is a critical state as I do not want to shock the tree after the trip, I would like to do everything possible to protect it and ensure viability.

A: Your Avocado tree looks great and healthy overall. You've done excellent job planting it. Wurtz is a good, vigorous variety, while the tree is somewhat dwarf, great for containers.
You are right, it is the best for the tree to leave it alone and do not trim or remove leaves any more, until it starts showing new growth. Then it will be obvious what needs to be trimmed. Reddish/orange color of young leaves is normal. If any spots or dots - no need to remove those leaves yet. Wait until the plant grows more leaves. It needs them for photosynthesis, in order to become stronger.

Keep the tree in bright shade and gradually move from filtered sun to full sun. Water daily. Within a week or two after planting, you can start applying mild fertilizer and micro-elements. We recommend at this growth stage:
SUNSHINE C-Cibus - Crop Nutrition Booster
SUNSHINE SuperFood - Micro-element Plant Booster

Plant food for a Star Fruit

Q: I have 2 Starfruit plants from you. One on the left is B10 has a lot of flowers but no fruit is developing. On the rite is Kenjeng. This one has no flowers at all. Both plants are growing very well. Plenty of sun and water. I am located in Boynton Beach Florida. So what to do?

A: Your trees on the pictures look very healthy, congratulations with a great care!
Starfruit, as well as other grafted fruit trees (like mango, avocado, etc) usually flower/fruit easily and readily while in pots in the nursery. Sometimes, once planted in the ground, they may reduce flowering or even stop flowering. What happened?
The answer is simple. In pots, we fertilize them on regular basis. In our nursery, we have fertilizer injector inline with irrigation system that dozes plant food with EVERY watering. In other nurseries, they may also use slow-release fertilizers, but it is still a regular routine to provide plant food to potted plants.
In the ground, especially in Florida poor soils, fruit trees may stop flowering or delay fruiting due to lack of nutrients, or dis-balance of elements in the ground. Without fertilizer, a tree may take extra time to develop bigger root system to reach out for necessary elements, and eventually will start fruiting anyway.
But we want it to fruit soon! The only way to fix the problem is to provide fertilizer on regular basis for a young tree. It is especially important during hot summer months when plant metabolism is fast due to high temperatures, plus nutrients may get washed away with frequent summer rains (like we have in Florida) even if you've added some fertilizer at time of planting.

You can use smart release fertilizer once a month during hot season, this one or similar:
Mango-Food - Smart Release Fruit Tree Booster.

But the most effective way to get a tropical tree to flowering and fruiting, is frequent applications of liquid fertilizer. We use Sunshine Boosters with every watering on our plants. They work great even on hard cases and weak plants, and you see the difference in a matter of weeks, sometimes even days.
We recommend the following fertilizer that contains all necessary elements for young fruit trees: SUNSHINE C-Cibus - Crop Nutrition Booster
