Q: When do you fertilize new bamboo trees and can you use the
same fertilizer you use for mango trees?
A:Bamboo is a tropical to subtropical plant with growing season
year-round. You can start fertilizing it right away with the exception of colder
months when temperatures drop below 65F.
Mango fertilizer is formulated for fruit trees, so bamboo won't benefit
from it. Bamboo is not a fruiting plant and is not even cultivated for
flowers. Its beauty is in healthy green foliage and beautiful stems. So you will
need foliage-type of fertilizers for it.
Helping Citrus and other fruit trees with Nutritional
Supplements
Q: Can you recommended a product to help with my citrus?
Combating greening and chlorosis.
A: Citrus greening is spread by an insect called the Asian citrus
psyllid. The psyllid feeds on the stems and leaves of the trees, infecting
the trees with the bacteria that causes citrus greening. Florida Citrus
growers dedicated the last decade to researching citrus greening. Officially,
currently there is still no cure, however, some Nutritional solutions have shown
promising results. To slow the progression of citrus greening in infected
trees, nutrients are applied to the leaves and to the roots. Providing better
nutrition helps trees fight against citrus greening and enables them to continue
to produce quality fruit.
We recommend the following products for use on regular basis:
SUNSHINE Epi is a natural Brassinosteroid plant hormone and a
bio-stimulant that may be very effective as citrus greening treatment. It works
through plant's immune system and shows amazing results of recovery of weak and
sick plants.
SUNSHINE Superfood, a complex micro-element supplement, maintains
plant's health and provides vigorous growth.
SUNSHINE-Honey is a basic nutritional complement, it contains essential
plant micronutrients Boron (B) and Molybdenum (Mo). These elements are essential
to vegetative and reproductive growth, cell expansion, tissue growth, and
fertility. A very common problem for most unimproved garden soils is lack of
Molybdenum and Boron as soil micro-component. This results in underdeveloped /
low quality fruit and/or premature fruit drop. Applying SUNSHINE Honey on your
fruit trees will fill that gap and help a fruit tree to form a healthy
fruit.
Macro-nutrients should be applied in combination with micro-nutrients on
regular basis:
Mango-Food - Smart Release Fruit Tree Booster (works great for all
tropical fruit trees)
Fruit Festival Plant Food - Ideal blend designed to improve fruit trees
health and vigor, and increase crop yield.
Q: I received my mango tree from you on Monday and it looked
beautiful. I followed the instructions and kept it out of direct sun. I watered
it a little each day when the potting mix was dry to the touch. But the leaves
are turning yellow and brown then falling off. Should I have removed the
tree from the soil it was packed in?
A: Leaf drop and dry/yellow leaves are normal symptoms of
shipping stress.
Your mango tree looks healthy overall. Considering you have high humidity
now in Louisiana, the plant should recover soon under proper care. These are
important tips:
- Keep the plant in bright shade, away from direct sun - at least for a
week, then you may start moving it gradually to semi-shade, then to full sun
within a few days.
- Do not over-water. If the top of the soil is still moist, do not
water until it dries a little bit. Mango prefers to stay on a dry side. From this
point, over-watering is more dangerous than under-watering. You may skip a
watering if in doubt.
- If it rains every day, make sure to keep the pot under the roof to
protect from excessive water.
- Do not remove original soil and do not disturb roots.
- You used the right container size and looks like you have a quality soil with good drainage. Keep the plant in this container at
least for a few months. You may step it up only when you see a lot of active
growth of branches and leaves - this means, the root system is developing fast
too.
- do not fertilize until you see new growth. Then use Mango Food Smart release.
- to help the plant recover from stress, you may use SUNSHINE-E booster and micro-element foliar spray with SUNSHINE-Superfood.
Q: I bought a Mango tree from you last month and planted it soon
after it arrived. When is the best time to fertilize it? (I am in Florida)
A: We always recommend to wait on fertilizing until the plant is
well established. If you planted your tree a month ago and it is doing well,
showing new growth, then this is the time to start giving it some food.
For a mango tree, we recommend using 2 fertilizers - water-soluble and
granulated:
Fruit Festival Plant Food
Mango-Food Remember micro-elements that are essential for healthy and vigorous
growth:
SUNSHINE SuperFood - plant booster
In Florida, this is the best time right now for fertilizing - while we
still have a few months of nice warm weather - active growth period. This will
help you Mango tree to establish well before winter rest.
Q: I have ordered dozens of trees from you and have a question
about Soursop. I have a Soursop in a container and ants and aphids are under
new leaves. Do Soursop like little water? I water almost everyday living in
southern Los Angeles it's been around 76-80F. I spray the aphids and ants off
with a mist setting on my hose. They come back every day. They're only on new
leaves...
A: First of all, you don't have to remove the ants iŠ° they
don't bother you. Ants are good insects, they do not harm plants; most likely
they are attracted by a sweet sap - aphid by-product. Ants clean up a plant,
and they may even take care of some bad insects.
It is not difficult to get rid of aphids. Use a safe treatment: in a
small spray bottle, mix 1 cup of warm water, 1 teaspoon of dish soap and 2
tablespoons of any cooking oil (if you have Neem oil or Horticultural oil - even
better, but prepare, they are pretty stinky). Spray the leaves with this
solution to a dripping point. Repeat in a few days if needed. This simple remedy
will take care of the aphids.
Daily water may be ok for the plant during hot weather, as long as the
soil is not constantly moist. Let the surface of the soil get a little dry
between waterings.

seeds
Q: I planted an avocado seed and it sprouted quickly, it has been
only a couple months and I already have a small plant. How soon will it
produce fruit? Can I grow other tropical fruit from seed?
A: Unfortunately, some fruit trees, including varieties of
avocado, mango, lychee, as well as apples and peaches - must be either grafted or
air-layered in order to produce, for 2 main reasons:
- seedlings may take a very long time until fruiting, up to 10-15 years
- seedling gives no guarantee on the quality of the fruit or variety
These fruit trees should be propagated as "clones" - both grafted
material or cuttings are actually copies of the mother plant and will keep the
same fruit qualities. Grafted trees usually start producing immediately.
However there is a number of fruit trees that come true from seed, and
take a very short time to start flowering. Jackfruit, Annonas (Sugar Apple, Guanabana, etc), Papaya, Icecream Bean, Eugenias start producing at a young age (3-4 years from seed).
Q: Can tropical fruit trees (Soursop, Mango, Star fruit, etc) be
given plant food any time of year? Also can they be trimmed this time of
year/summer?
A: True tropical plants (including fruit trees) need plant food
most of the year in real Tropics, where temperatures have very little
fluctuations, and active growth season is close to 12 months a year. In subtropical
areas when temperatures in winter drop below 65F, plant metabolism slows down,
so it is recommended to fertilize only during the warmest period (March
through November). So yes, Summer is the perfect time for fertilizing your trees;
their metabolism is at the highest point and they can use more food!
Trim your fruit trees right after harvesting. Obviously, you don't want
to prune branches before or during flowering or fruiting. The specific time
of the year for pruning depends on the plant - every tree has its own
flowering/fruiting season. However, avoid pruning right before winter: young shoots
promoted by pruning are tender and can be cold damaged.
Q: On the website, it says that the pua keni keni tree is toxic.
Do you know how toxic? Is it mild irritation or can someone die from
ingesting any part of the plant?
A:Pua Keni Keni, Fagraea - seeds (and especially flesh of the fruit) are
toxic, so we recommend to always wash your hands after handling them.
Obviously, nobody in our team ever tried to eat them to check how toxic
they are and if they are deadly.
In general, one must be careful when using plants for purposes other
than ornamental growing, especially for consumption. While some obvious edibles
(cultivated fruit, vegetables, herbs) are generally safe, but some
individuals may have severe reactions - for example, many people are allergic to
mangoes; other people may be sensitive to only mango leaves.
A number of plants that have parts commonly consumed for food, have
other parts toxic or poisonous. Example: Potato - Solanum tuberosum - has edible
tubers feeding the whole planet population, but this plant's fruit is highly
toxic and even deadly if eaten. Fruit from a Potato plant look like tiny
little green tomatoes since Potato belongs to the same family as Tomato -
Nightshade, but it is super poisonous, while Tomato fruit is perfectly edible. So
one must watch out and especially educate little children about not tasting
anything directly from the garden.
As far as animals concern, in Nature they know what is poisonous and
what is edible. Have you ever seen dead birds around a tree with poisonous
fruit/seeds? Animals have their own sense for it. So if your concern is for pets,
it is normally safe to have pets around plants with irritating or even
poisonous parts. However, if your dog has a bad habit of chewing on stuff, you may
use extra caution there.
Q: Is it possible to grow soursop in a large pot for life?
A: Soursop, or Guanabana - Annona muricata - is actually one of those tropicals fruit trees that
can be easily cultivated in a container. Most plants of genus Annona have compact nature, and these fruit trees usually start
production at a young age, as early as 3 years from seed. Annona muricata
seedlings take a little longer to fruit, this is why we offer grafted trees, which can start producing right away.
We have a very interesting article about growing Soursop in an
apartment. The article was written by an indoor gardener who lives in a very small
apartment in Moscow, Russia. He grew this tree from seed and after years of
cultivation fun, he finally got several large delicious fruit! It is an amazing
story. We have it published in our Tropical Treasures magazine, download the whole issue #7, get a hard copy, or you may download PDF file of the single article.
Q: We leave in zone 6a, could you tell us what is the list of
different types of mango plants that could be planted indoor and that they can
bear fruits?
A:There is a large group of mangoes called "Condo Mango" - they
literally can be grown in your apartment! Those are dwarf varieties that can
remain compact in containers with minimal pruning and successfully bear fruit
providing bright light and proper care, including plant food.
They produce juicy, fiberless sweet fruit. Julie is also a very popular
dwarf variety, however, it is very cold sensitive and not the easiest to
grow. If you get a 3 gal size mango, step it up to 7 gal when the plant reaches 4
ft; you may use a bigger container as the root system grows, up to 15 gal or
even 25 gal, space permitting. Trim the tree under 6-8 ft after production
season is over (summer-fall).
