Cold hardy tropical fruit trees for Luisiana
Q: I've just moved to Louisiana and have been wondering whether it would make sense to plant some tropical fruit trees in our garden. Average lows in New Orleans are 41 deg F in January and February, although we did hit 25 once with the Arctic vortex. I'm interested in litchi, longan, rambutans, and persimmons. Do you have varieties that can tolerate Louisiana's temperature range? I'd love mangosteen but I don't suppose they will survive. Do you have any suggestions on tropical fruit trees that I could try?
A:
Average temperatures are for statistics only; it is actual
temperatures that may hurt your cold sensitive plant. This
is what you should keep in mind when starting your
tropical fruit collection:
1) Ultra-tropical plants like Rambutan can not survive
winters below 45-50F. However, they can be successfully
grown in containers in a greenhouse or moved indoors into
a sun room during cold periods.
2) Tropical plants like Litchi and Longan may take some light
frost once established. Still, for areas with freeze our
advice is - keep them in pots and move inside in case of
cold.
3) There is a number of subtropical fruit trees that are
hardy enough to take some freeze. Persimmon, Feijoa, Fig, Cattley Guava, Jujube, Kiwi, some Eugenias and others. Please
refer to our Tropical Fruit Sensitivity Chart.
4) Remember that plant's ability to survive winter depends
on several factors, not only temperature itself. Important
factors are: wind protection (chill wind kills rather than
low temperature itself), exposure, how close the tree is
planted to the house, plant maturity and its overall
strength and health. If a plant had received good
nutrients during summer, has well established root system,
planted in enclosed area protected from winds and has
plenty of bright sunlight - it has better chances to
survive than a weak plant in warmer conditions.
5) Use SUNSHINE plant boosters

Cleanest fruit?
"Dirty" fruit: According to the Environmental Working Group research, Strawberries are top the list of the 12 "dirtiest" fruits and vegetables grown commercially. Spinach is the second, followed by (in order of contamination) nectarines, apples, grapes, peaches, cherries, pears, tomatoes, celery, potatoes and sweet bell peppers. Each of these foods tested positive for pesticide residues and contained higher concentrations of pesticides than other produce. This causes of course chronic health implications. Children are of special concern as younger bodies have greater susceptibility to pesticides than adult bodies, the report emphasizes. Pesticides may induce chronic health complications in children, including neuro- and behavioral problems, birth defects, allergies, asthma, and even cancer...
"Clean
15": Avocados lead 2018's clean fruits and
veggies list, that also includes: mangoes, papayas, pineapples, kiwi, sweet corn, cabbage,
onions, frozen sweet peas, asparagus, eggplant, honeydew
melon, cantaloupe, cauliflower and broccoli.
Obviously, home grown fruit and vegetables are even
better. Such fruit as Custard Apples, Sapodilla, Sapote, Jackfruit, Dragon Fruit, Passion Fruit and other rare
varieties of tropical fruit, are even better for you
because they are not grown commercially, and the choice
from your own organic garden is the healthiest for
yourself and your family!
Plant them today and get your cleanest fruit tomorrow!

Why my Avocado is not flowering?
Q: I have 5 avocados. Three of your cold hardy varieties and two others that have all flowered and set fruit in the past. The last two years including this year, not a single one of them has put out any flowers. I am getting lots of new growth like one would expect on a tree too young to flower. The last two years have been very mild with out any damaging frost where in previous years they lost all their leaves due to frost yet started putting out flowers once winter was over. I am confused because they have all flowered and set fruit previous years. Any ideas would be appreciated.
A: From information you provided, and considering the trees get
lots of full sun and cold was not an issue, the only explanation is - lack of
nutrients. Here is an example.
Very common situation: you get a small 2-3 ft Avocado or Mango tree in 3
gal pot (or even smaller) from a nursery, full of flowers, and sometimes even a
small fruit. You bring it home, plant it in the ground or a bigger pot, it
looks happy and grows like crazy. Then next year - oops, no fruit, sometimes
not even flowers. What happened?
When the tree lived in a nursery, it was provided with all necessary
nutrients through the injector systems (continuous feed); or some nurseries may use
top dress smart release on regular schedule. Regardless of fertilizer type,
professional grower's set up delivers plant food non-stop, on regular basis, with balanced formulas. Plants are not only growing fast but also ready to produce, since nutrients are always available for a full growth cycle.
When you plant a tree in the ground (or larger pot), conditions change.
They may be beneficial for the plant: lots of room for roots to establish, hence
lots of vegetative growth. Even if you planted it using good quality fertile
soil, this soil may contain mostly nutrients responsible for vegetative
growth (branches and leaves). Chances are, your soil may be rich in Nitrogen
(good for green growth), but poor in other elements responsible for flowering and
fruiting (Phosphorous, Potassium, and many important micro-elements such as
Molybdenum, Boron, Iron, etc.). Besides, existing soil gets exhausted
quickly, and within a year a two, if you don't add fertilizer, flowering and fruiting may be reduced or even stopped.
This is why fertilizing program is very important for fruit trees that are expected to bring a crop soon.
We recommend:
- SUNSHINE C-Cibus - Crop Nutrition Booster - balanced food for fruit
trees
- SUNSHINE-Honey - sugar booster - promotes more efficient blossoming and
pollination, makes flowers bigger and reduces bud drop
- SUNSHINE SuperFood - for improving fruit trees production
Also keep in mind that some fruit trees have a habit of "skipping" a year and may either produce less or not produce at all every other year. In any case, balanced nutrition program can help to fix this "bad habit".

Ylang Ylang leaves after winter
Q: Hi, I purchased ylang ylang tree a couple of years ago. It's grown quite well in my Greenhouse but I'm having some trouble figuring out if I'm watering it too much not enough or if it has an insect. Can you please take a look at my photos and maybe give me a suggestion of what my problem might be?
A: It is normal for Ylang Ylang tree to get dark spots during
winter time. Sometimes Cananga gets whole branches darkened (especially dwarf variety fruiticosa), some may even fall off. But they will be replaced
with new growth in Spring-Summer. There is nothing wrong with your plant, it is
just a reaction to cold and short day light when you keep this plant indoors. These leaves eventually will fall
off as the weather warms up, and will be replaced with a new fresh green growth.
Luckily, Cananga is not susceptible to insects and diseases, but its leaves
can look unattractive in winter.
Make sure to keep watering at minimum until temperatures raise to 80's.
Start fertilizing as soon as new growth appears. We recommend SUNSHINE Pikake
- Fragrant Flower Booster, an ultimate fertilizer for fragrant plants.

Fertilizing in Winter
Q: I have many tropical plants in my garden, both in the ground and in pots. I realize it is wintertime and some of them, the Hydrangea, Hibiscuses, and roses are in bloom but the rest of them seem wilty and droopy. Is it alright to fertilize them now, or should I wait for a few days? I have an all purpose tropical fertilizer and a 20-20-20 also. Please advise what to do.
A: During wintertime, tropicals may suffer from low temperatures
and lack of sunshine which causes droopy leaves, and leaf loss.
Regardless of the cause and plant condition, you should NEVER apply
traditional dry fertilizers during cool months. When cold, dry fertilizers
(EDTA-chelated) may create nutrient lock up in soil and damage the roots. Dry
fertilizers (both granulated and water-soluble) can be used only during hot season -
when min temperatures stay above 65F for at least a week in a row, and
daytime temperatures are over 75-80F. During hot, active growth season plant
metabolism increases. This provides less chance for a chemical root burn, as the
nutrients are used up quickly.
However, liquid fertilizers, as long as they are amino-acid based, can
be used year round. From our own experience last winter, we discovered that
fertilizing sickly looking plants (with signs of cold damage and root issues)
with Sunshine Boosters actually revived those plants. Sunshine Boosters even
brought back to life some hopeless specimens. Take a look at this gardenia
that grows in our garden (picture above). See full article.
In your case, it would be beneficial to use a mild formula of liquid
boosters in combination with Sunshine Epi -a natural plant hormone that boost their growth and helps
to cope with cold-, temperature- and low-light-related stress.
These are the products we recommend:
- Sunshine Bombino - add to every watering
- Sunshine Epi - twice a month as foliage spray
Since you grow plants in pots, feeding program is especially essential,
because plants are limited with a container size where roots can't reach out to more food in the outer soil.
In professional nursery set up with injector irrigation systems, container plants are fed daily (depending on season, more than once a day) with every watering. This is why greenhouse plants are so healthy looking.
So feel free to give your plants Sunshine boosters with every watering,
dozing according to the label. During cold period, plants need less frequent
watering, so fertilizer input will be balanced accordingly, it will depend on
temperature and plant metabolism.
Sunshine Bombino - mild, "pampering" formula for young and tender plants, as well as plants recovering from stress and/or winter damage.
