Cold protection of tropical container plants
Q: I am long time customer of yours, I live in San Diego California and while the summer and Fall temperatures are warm to mild, the winter temperatures dip to a point where some tropicals die off. We are experimenting with different variations of way to heat and insulate the pots we have the tropicals planted in as a way to keep them alive during the colder winter months. I was wondering if you knew of the ideal soil temperature for these tropical in order to look their best year round. All of the heaters we have installed have thermostats and temperature adjustments so we can now keep the soil anywhere between a range of between 65-75 degrees. Any advise you can provide would be greatly appreciated.
A: This is a very interesting concept you are working with.
Indeed, keeping pots/roots warm, may help a lot! We've been experimenting with
cold protection for a long time - for the above-ground plant parts. For sure
keeping roots protected (even with a thick layer of mulch) will benefit tropical
plants during winter. In case with container plants, this may help
dramatically.
The guideline is, tropical plants slow down or stop their metabolism at
65F. As long as you can keep soil above that temperature - this should work
great. Of course, the higher the better.
Optimum temperature for growing tropical plants in general - 70-85F.
Above 90F, metabolism stops too, unless it's a heat tolerant, desert
plant.

Ghost Cold Protection
Q: Has anyone ever tried using heat packs under frost blankets to protect tropical plants from frost?
A: The reality is, the heat packs used for shipping do not have enough heat capacity to create efficient warming effect. From our own experience, the best way is to use small 25W incandescent bulbs which produce lots of heat (considering observing all safety precautions and fire safety). Some gardeners use Christmas lights. See picture of our plants in the ground during a cold night. We called them Ghost Cold Protection! ;)

Fast-fruiting trees
Q: It would be easier for us buyers, if we could search for plants that produce fruit in 2 years or less... I don't have the patience to wait longer than that for fruit. I'm trying to buy for a fairly good sized garden but want some fast growers and fruit produced in 2 yrs. Can you help me out?
A: Fruiting time depends on many factors (growing conditions,
fertilizing, and even specific variety), this is why we can not just put a
simple icon "will fruit within 2 years".
However, most grafted and air-layered fruit trees, including all Mango, Avocado, Loquat, Sapote, Sapodilla, Longan, Peaches and Nectarines - will fruit right away.
If you see in our store "grafted" or "air-layered" in plant description
- these trees will fruit soon. Some of them are already flowering and
fruiting!
Some non-grafted trees will fruit within a couple of years or even sooner (those from cuttings, root division or even seedlings) - such as: Annona, Artocarpus (Jackfruit), Eugenia, Guava, Banana, Dragon fruit, Mulberry, Blackberry/Raspberry. Banana, Mulberry, Dragon fruit, Blackberry-Raspberry - usually fruit within a year. You may refer to our store directory page for fruit specials.
Also, all spice trees like Bay Leaf, Bay Rum, Allspice and many more - will produce spice for you right away, so you don't need to wait at all!

Dwarf and Condo mangoes - easy mangoes
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.
The best dwarf and semi-dwarf varieties are: Carrie, Cogshall, Cushman, Fairchild, Graham, Ice Cream, Julie, Mallika, Nam Doc Mai, Pickering, Irwin, Jahangir, Juliette, Lancetilla, Little Gem, Manilita, Sia Tong, Torbert, Pim Seng Mun, Super Julie.
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).

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.
