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.

Save Coffee from extinct!
The most popular kind of coffee for commercial production, Coffea arabica, is already on the endangered species list. According to research, Coffea arabica plant could become extinct in as little as 60 years.
Coffee requires a forest habitat for its survival. With so much deforestation going on around the world, wild coffee species are being impacted at an alarming rate. Coffee plants grow in very specific natural habitats, so rising temperatures and increased rainfall brought by climate change can make coffee impossible to grow in places the plants once thrived.

SUNSHINE boosters for small and large gardens
Q: I tried your magic SUNSHINE booster on my Champaca tree and results were amazing. The tree was having a hard time establishing after shipping and didn't want to grow, losing leaves. I almost lost it. Then I sprayed SUNSHINE booster and right after the first application the plant perked up and new leaves grew within a week. Now I want to use this stuff on all my plants. I am a plant collector, with a few hundred pots and almost a hundred plants in the ground, living in California. I wonder if you have bigger size bottles of SUNSHINE so I can use on my flowering plants, and fruit trees, to promote blooming and fruiting. And another question, how often should I spray my plants? Your instructions say once in 20 days, should I spray more often for better results? Should I water through roots too? Do I still need to fertilize plants or SUNSHINE will be enough for their health?
A: Great news! We just added new SUNSHINE items to our store, 50 ml and 100 ml - bigger bottles, they will be great for small and big gardens, as well as small plant nurseries and plant businesses. It is a good idea to start bi-weekly applications to improve your plants tolerance during winter time to cold and low light, especially when it comes to house plants. SUNSHINE improves plant resistance to insects which is a big deal during winter, when we bring tropical species indoors.
SUNSHINE is indeed a wonderful plant stimulant and stress reliever, although it is not a "magic-cure-all" medicine where one can't find its active ingredient. The hormone (epibrassinolide) is well-known and used in different countries along with other hormones for promote growth, fruiting, blooming, rooting, etc.
One of the most amazing properties of SUNSHINE is that it works in extremely low dozes. Only a few drops will be enough to make a solution in distilled water, to treat a large size plant. If you want to try it out, one 5 ml bottle will last for several applications.
The formula works through plant metabolism within 2-4 days, repeat application not sooner than in one week. The formula is created for absorption through foliage, not roots, so do not try to water with solution. Plants should be evenly sprayed in clear windless day. Do not spray if rain is expected. Re-spray if it rains within 12 hours.
Remember that SUNSHINE is not a fertilizer and won't replace it. You have to apply fertilizer (except during winter months) and micro-element solution to keep your plants healthy.

Growing fruit trees in containers
Will it fruit in a pot? YES!
Many tropical fruit trees can be grown in a pot. We get many calls from customers in cooler climates asking if our tropical trees can grow and fruit in a pot. The answer is yes!
Several plants fruit well in pots. Blackberries and raspberries, barbados cherries, blueberries and many more start fruiting even in their 1 gallon containers. We are especially excited about our new Pixie grapes, which are heavily laden with grapes even at only a foot long!
While some plants are small and will fruit easily in a container, others are large trees. For the tree type fruits, we recommend growing only non-seedling plants for pot culture. We have cuttings, air layers and grafted plants that are great options. These have the ability to fruit right away, as they are the same age as the parent tree. Some horticulturists recommend removing the first year fruit to allow the plant to focus on growth and establishing. If the plant is being kept in a pot, this is not necessary.
We also have several dwarf varieties of fruit trees that will thrive in a pot. For avocados, we carry the Wurtz variety which is a dwarf tree... read more...

Jungle on Windowsill 101
Q: I got a Jasmine Sambac and a Tahitian gardenia as presents, they are very cute plants with flowers and flower buds. I would like to be able to keep them alive and hopefully happy for a long time, but I don't know much about growing tropical plants, and I am not sure if my thumb is green enough to make everything right. What do they need? How much sun? How much water? What kind of soil? Sorry for all these (maybe silly) questions, but I want to keep them alive, please help! I live in Wisconsin and we had some snow again last week.
A: Growing tropicals is not a hard work, it is a lot of fun! These plants are actually a good starters for a beginner who wants to try growing tropical plants, no matter if you live in a mild frost-free climate, or up North where you can have these beauties as houseplants. Below are a few simple steps for you:
1. Read. Follow planting instructions included with your plants. Check plant names on the tags and learn more about them from our online catalog.
2. Soil. Plant in quality potting mix - it must be porous and well-drained, never use heavy soils (top soil or garden soil are no-no), in a pot exactly the size of the root system. You can step up your plants in the next size container once you notice vigorous new growth. Next size means: 4"pot can go into 6" pot, 6"pot into 10" pot, etc. Too big of a pot may create rotting environment, root system must fill the entire container to use all the moisture from the soil. Container must have good hole(s) for excess water to drain through. Put the pot in a saucer and get rid of excess water every time after watering.
3. Light. Most tropical plants require lots of light in order to produce flowers. If you ever visited Florida, remember the bright sun? - these are ideal light conditions for tropicals. Up North, provide as much light as possible: a bright spot on a windowsill of Southern or Western exposure would work the best. If the sun gets too hot in summer afternoon, you may shade the window a little bit with a sheet of white paper to avoid leaf burn.
4. Water. Keep soil slightly moist but not soggy. The best way is to wait until the top of the soil feels dry to touch - this is time to water again. Jasmines prefer to stay on a dry side; gardenias do not like soil to dry out - keep them slightly moist as long as soil is very porous and well-drained.
The main reason of most problems with potted indoor plants is over watering. With experience, you will feel the right balance of moisture in the soil: the brighter the light, the more water is consumed by a plant; the less light, the less frequent you should water.
5. Trimming. In low light conditions, plants tend to become leggy. Trim branches as they become too long: the more you trim, the busier the plant gets. New growth promotes more profuse blooming in many species.
6. Fertilizing. Fertilize indoor plants with slow-release granulated fertilizer from march to November.
7. Insects. Check for insects at least once a month, especially underneath the leaf. If notice any problems (deformed leaves, residue, holes, or tiny insects) - clean the leaves/stems with a solution of warm water (1 cup), vegetable oil (2 table spoons), and a few drops of a dish soap.
8. Fresh air and air humidity. As soon as air temperature gets above 65F, bring your tropicals outside in the sun and fresh air: porch, balcony, outside in the yard. Air circulation is essential for your plant health. Bright light and high air humidity will promote vigorous growth, and lots of flowers for you to enjoy!
