URBAN TROPICAL GARDENING:
10 secrets of successful Container Mango growing on a
balcony.
Q: I live in Miami in apartment on a second floor, and I have a balcony with SE exposure. I wonder if I can grow a mango tree in a pot? Will it fruit for me? I recently moved to South Florida and I don't know much about tropical plants; but I tasted real fiberless mangos from someone's garden - it was so delicious and different from those in the grocery store. I wonder if I can have a fruiting tree on my balcony? And if yes, how do I plant and take care of it?
A:
Yes, you can! Here is what you need to do:
1) Temperature. You are lucky to live in Tropics,
keep it on a balcony year round.
2) Light. Position the pot in a spot with the most
sun exposure. Mango trees can take filtered light too, but
the less sun, the less fruit you will get.
3) Soil and Container. Use only
well drained potting mix. Step up the purchased
plant into next size container (3 gal into 7 gal, 7 gal
into 15 gal). When transplanting, make sure to keep growth
point (where roots meet the trunk) just at the top of the
soil. Covering base of the trunk with soil may kill the
plant.
4) Water. Water daily during hot season, but only
if top of soil gets dry. If it still moist, skip that day.
Mangoes (unlike
Avocados!) prefer to stay on a dry side.
5) Fertilizer. Use
balanced fertilizer once a month, 1 tsp per 1 gal of
soil. Do not fertilize during fruiting - this may cause
fruit cracks.
6) Microelements. Apply
SUNSHINE-Superfood once a month. This will help your
mango healthy, vigorous, and resistant to diseases. Use SUNSHINE-Honey to make your
fruit sweeter.
7) Insect control. Watch for scales and mealybugs,
clean with solution of soapy water + vegetable oil (may
need to repeat 2-3 times with 10 days interval), or with
systemic insecticide like imidacloprid only as needed (if
non-harsh treatment didn't help). Most Flea shampoo for
dogs contain that chemical, you may try that shampoo
solution.
8) Trimming. Once potted, do not remove leaves
that are discolored or have spots until new growth
appears. Dark dots on mango leaves, especially in humid
climate like Florida, may be signs of fungus. Treat with
fungicide according to label, and remove only badly
damaged leaves. Trim crown as needed after flowering and
fruiting (by Fall). Train into a small tree, and you may
remove some lower branches eventually.
9) Flower and fruit. Mangoes are winter bloomers
with bunches of tiny flowers coming in thousands. Many of
them set fruit (if pollinating insects present). Keep in
mind that young trees can only bare a few fruit. Normally
a tree will drop excessive fruit and keep only a few that
it can manage. To save the young tree some energy, remove
fruit if too many and leave only 2-3 for the first year.
It will pay you next year with more abundant crop.
10) Variety. Last but not least: Choose the right
variety for container culture! Pick from "condo" dwarf
varieties such as Icecream, Nam Doc Mai, Carrie, Cogshall, Julie, Fairchild, Pickering, Graham, Mallika, and a few others -

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!

Condo Mango
Q: I was curious about indoor fruiting mango trees. I live in upstate New York and was thinking about trying to grow an indoor tree for fruit. I have a small heated greenhouse. Is there a variety that can be grown from seed that would suit my purposes and if not what is the most economical way I could obtain a cutting or small grafted plant? I keep my greenhouse around 60F in the winter and have no supplemental lighting. Are there any varieties that may work in a sunroom or other well lit indoor location?
A:
There are many dwarf varieties of mango suitable for container culture. They
are called "condo mangoes".
The most popular condo varieties are: Carrie, Cogshall, Cushman, Fairchild,
Graham, Ice Cream, Julie
, Mallika, Nam Doc Mai,
Pickering. You may read more about them in our online
catalog. You may also look into variety
Lancetilla which is also a compact tree, and produces one of the biggest size
fruit, up to 5 pounds. If you want some rare variety that hardly anyone else has -
try Baptiste, an exotic Haitian dessert
mango.
Your greenhouse should work for the winter time. Mango trees can take
as low as mid 40s during winter and even lower as long as that cold is
occasional. If you keep the temperature around 60, this should work well for over
wintering. Just make sure to reduce watering to a minimum, because cool
temperatures, low light and wet soil - is a bad combination for tropical plants,
especially for mango trees which prefer to be kept on a dry side.
Many indoor gardeners have fruiting mango trees in their collection. However,
keep in mind that the most important requirement for a mango is full sun.
While you may over winter the plant for a few months in a low light conditions,
in order for it to flower and produce fruit it needs lots of light. If moving
the tree into full sun your yard during the summer is possible, this would
be the best solution.
We always recommend
SUNSHINE boosters for both over wintering tropical plants in colder
climates, and for indoor gardening. SUNSHINE applications will help your tree to
cope with cool temperatures and low light conditions. This will also
dramatically increase flowering and fruiting performance. Another important factor for
keeping your container plant healthy is quality of your potting soil. We
offer a special
professional mix that contains lots of good stuff: coconut fiber, peat moss, pine
bark, and perlite. Fertilizing potted plants
is also very important during the warm season, because this is the only way
for them to get nutrients (which in the ground can be reached by spreading
root system).
As far as seedlings vs. grafting - the only way to
have a nicely fruiting mango tree is to plant a grafted variety. Seedlings start
producing only after 8-15 years, and the quality of such fruit may be
questionable. Only grafted plants can guarantee the desired taste of a variety.
Besides, grafted mangoes start producing immediately - you may see fruit forming
on plants as small as 3 ft, in 3 gal containers. However, during the first
1-2 years you will need to remove extra fruit and leave only 1-2 fruit so the
plant doesn't get exhausted and has enough energy to establish strong root
system.

Growing tropical fruit trees in containers in winter
Q: Please give me your advice. The winter is here. I bought mango tree, jackfruit tree, sugar apple tree and planned them for spring. What can I do to keep them no frost bite? My home in Bonifay FL.
A: In
subtropical areas with occasional hard freeze in
winter, we recommend you to keep tropical plants in
pots. The plants you purchase are tender to frost. For
cold protection, container growing has several
advantages:
1) easy to move into wind-protected and sun-exposed
locations as needed: for example, on a different side
of the house. In many areas, seasonal prevailing winds
have opposite directions in Summer and Winter.
2) easy to cover with frost cloth, sheets, or blankets
in case of immediate cold spells. Container plants'
growth is easier to control and trim, and those plants
naturally stay more compact.
3) easy to move indoors, inside garage, or in covered
lanai/patio.
We also recommend to keep these trees in their
original pots until Spring, in containers size of the
rootball. Step them up in Spring, when plants start
active growth of root system. This will help you to
avoid root rot due to possible overwatering in Winter.
Reduce watering in any case, and keep your plants in
bright, wind-protected spot. Do not fertilize until
Spring. Protect from cold when night temperature drops
below 35-40F.
Use SUNSHINE plant boosters
to provide additional cold tolerance.
Cold protection is a lengthy subject. You may also use
propane heaters during cold nights.
Here is some more information on cold
protection.

Taking care of Guanabana (Soursop) after shipping
Q: Since I have never grown a soursop tree before I need some pro help. My tree was delivered absolutely beautiful, leaves were a pretty green. I potted it and gave it a good drink of water and put it in a shaded area outside. Then the weather here became cool so I brought it in for a few days until the weather warmed, and it lost all the leaves. Is it in shock and will come around eventually? Will I be able to grow this tree indoors during winter?
A: Soursop - Annona muricata trees are very sensitive to temperature drops. This always causes leaf loss. You seem to be doing everything right. Do not water until soil gets slightly dry; keep it in bright shade. The weather should be good now with high temperatures and humidity rising. No fertilizer until the plant shows active new growth. Be patient with your plant, it should recover soon.
Soursop is an ultra-tropical tree and doesn't take any freeze. If you live in cooler climate, keep the plant in a pot (the good news is,
Annonas in general have compact nature and are perfect for container culture). Bring the tree indoors during cold period,
providing bright light.
Remember that grafted trees start flowering and producing fruit right away, unlike seedlings of Soursop that may take a few years till
fruiting.
We have very interesting article about growing and fruiting Soursop in apartment. Check out Tropical Treasures Magazine #7.

Happy Holiday Season!
WINTER COMING TIPS. As the weather gets cooler, many of you move your potted tropical plants indoors. Please remember:
1. Lower air humidity, lower light and short day may cause some LEAF DROP. This is normal for seasonal environment change.
2. REDICE WATERING as winter coming. Under lower light and in cooler temperature, plants won't need much water; some plants go dormant and only need minimum water. Excess water may damage roots and kill a plant in winter.
3. NO FERTILIZER in winter. Active growth stops. Let the plant to go into dormancy or simply have a rest.
4. Watch for INSECTS by inspecting leaves regularly. They may attack plants more likely in the indoor conditions.
5. Apply SUNSHINE boosters to protect your plants from cold by boosting their immune system, vogor and cold tolerance.

Overwintering Adeniums outside of tropics
Q: We bought several adenium plants from you. We are moving to the Denver area of Colorado. How can we make sure the plants survive? Should we use a green house?
A: Adeniums are perfect container plants, and house plants. They can be easily grown outside of tropical climate. During winter, Adeniums drop leaves and go into dormancy which makes it easy to keep these plants in a dormant stage in a warm location of your house, or possibly even in well-lit spot of garage (with a window), with temperatures above 50-60F.
Here in South Florida, during time of cold, when chances of freeze are high, we move our own Adenium collection into lanai, with plastic sheet protection around lanai.
In colder climates, Adeniums can be kept indoors as house plants during winter. There are some requirements/tips for you:
- Temperature. Move Adeniums indoors when temperature starts dropping below 45F.
- SUNSHINE. Use SUNSHINE boosters to improve cold resistance of Adeniums, and essure healthy plant throughout winter. SUNSHINE-BC formula is specifically designed for plants with caudex, and bonsai.
- Water. Reduce watering to minimum, especially when plants drop leaves - this means they went into dormancy. Once a week light watering is enough. Water very carefully during cooler months. When it is hot (85-100F), excessive water usually won't harm adeniums: it will be partially used by a plant, and partially will evaporate. Especially be careful with water when temperatures drop below 65F - then tropical plants simply stop growing process and go dormant. Once adeniums start losing leaves, this is a sign to reduce watering to once a week to once a month, and in very small quantity (couple tablespoons per pot).
- Light. Bright light is not necessary, but do not keep them in dark either, even if all leaves dropped. Good light is necessary to maintain healthy stems and caudex. Keep in mind, the less light, the less watering too. Ideal spot is a windowsill, however if your space is limited and all windows occupied by other "leafy" plants, location close to window will be enough as long as watering is reduced, to avoid rot. We keep our big collection specimens on a roofed porch during winter, where level of light is very low. Last winter we haven't lost a single plant due to low light. They take shade pretty well considering minimum or no water. However bright light is always better - it creates healthier environment for a plant. We all know about space limitations for our large collections, especially in winter. So if you can afford a bright spot for adenium during winter - the plant will be lucky!
- Soil. Use only well drained mix with much higher content of perlite than you would use for most tropical plants. For adeniums, we use mix with 30-40% of perlite in it, while regular mix has 10-15%. Adeniums like alkaline soil, unlike most of tropical plants (hard to say what else likes alkaline... Ficus for sure!). This means, regular mix with high content of peat moss may cause root rot. To increase alkalinity, you may add dolomite. Here in Florida where we have natural supply of shell rock handy, it is easy to add some shell to a potting mix (shell sand, rather than quartz sand). We always add a few large shells on top of a pots with a big specimen. Besides increasing soil pH (making it more alkaline), shells look very decorative.
- Fertilizer. No fertilizer until Spring when plants start showing new growth and new leaves.
- Move your Adeniums outside in Spring, when chances of freeze are zero. More sunlight and air circulation is beneficial for breaking the dormancy and providing plants with a quick growth start.

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...
