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.

Cold protection - winter action for your plant collection
A note from our customer: Last winter was very cold here in Arizona, lower 30's. I used white synthetic sheets (called frost cloth, it is very light and yet effective) to cover my fruit trees, and kept simple light garlands on for the whole night. Sending you couple photos so you can share with others. It worked pretty well for my plants and no cold damage!
With winter approaching, it is time to take some actions to protect your rare plants from cold stress and damage.
If you live in a mild climate, you still need to get ready for the cold nights. When expecting a cold night, individual plants and trees can be wrapped with sheets, or blankets, to protect them from the wind chill. Christmas lights is a good idea for an additional warm up.
For large collections of tropical plants, temporary winter greenhouse doesn't have to be expensive. An easy-assembly mobile carport from a hardware store covered with a plastic or fabric will cost you $100-200. It can fit a hundred plants or more!
If you live in area with a hard freeze, Southern exposure windowsill will work for most of the compact tropicals providing proper care. Larger collections may also move into your garage for a few cold nights, or for longer periods if the garage has a bright light source.
Factors affecting tropical plant winter survival:
1. Duration of cold period. Tropical plants can't stand long periods of cold. A few days of even upper 30's may kill a tropical plant. A few hours of frost may cause leaf drop but the plant will recover.
2. Minimum temperature - of course, the warmer the better. But see 1) - if cold is not for too long, it may be OK.
3. Wind-chill can be more dangerous than low temperatures.
4. Exposure. Southern slopes get warm during daytime and stay warm longer.
5. Protection with a house, fence, larger trees - where a "pocket" of warm air forms and stays - is beneficial.
6. Humidity. A lake or a river nearby (especially ocean) will mild the micro-climate.
7. Individual species hardiness. Don't try to grow Orchid Tree outdoors in New York.
8. Plant maturity and health. A well-established plant with developed root system has more chances to survive cold. If a plant had a good change to develop during warm season (bright light, enough water, fertilizer), it will be more cold hardy. Healthy plant can withstand lower temperature, so proper nutrition is important, including micro-element applications. Large specimens, even ultra-tropical, may survive cooler winter than they normally do in their natural habitat. The Nature provided plants with better hardiness level than it is normally used. To boost plant immune system and improve cold tolerance even more, use SUNSHINE plant boosters. SUNSHINE-T

Guava is one of the most popular and well-known tropical fruit because
it is so tasty, sweet, juicy and flavorful! Many people are familiar with it
because of the large number of products made from this aromatic fruit. But
very few people know that Guava tree culture is very easy and this plant can
fruit in a pot right away. Guava tree start blooming and producing fruit as
small as 1 gal pot size. It can be kept in compact shape, responds well to pruning, stays bushy and grows very fast. It
is a perfect container fruit tree or a specimen for a tropical garden of any
size.
Upon ripening, the fruit becomes soft and juicy. It may be eaten fresh,
made into a juice or nectar contain fruit pulp, or made into preserves, jam,
jelly, or paste. A distinctive, savory-fresh aroma of fruit is thermo-stable,
thus survives processing. The guava is an excellent source of vitamins C and
A.
The plant is relatively cold hardy. Our young trees, 3 months after being
planted in the ground were exposed to a short period of freeze last winter
(mid-20's) but they grew back without significant damage. Try to keep Guava
cold-protected for the first winter, then it will be much hardier once
established.
Guavas are fast growers and heavy feeders, and benefit from regular
applications of fertilizer. Make sure to get some Sunshine Boosters fertilizer: Sunshine
C-Cibus - Crop Booster, and feed them your round.
