As the weather gets cooler, many of you move your potted
tropical plants indoors.
Please
remember: 1. Leaf drop. Lower air humidity, lower light and
short day may cause some leaf drop. This is normal for
seasonal environment change. Learn more about leaf drop
and deciduous plants from this info sheet
(PDF). 2. Reduce 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 go into dormancy or simply have a rest. 4. Insects. Watch for insects by inspecting leaves
regularly. They may attack plants more likely in the
indoor conditions.
STAY WARM!

How much water?
Q:
I have purchased many tropical plants from you throughout
the summer and now I need to think about how not to kill
them overwintering in my NY apartment. I was told that
overwatering can be a big problem for house plants in
winter. How much should I water, and how many times per
week?
A:
Overwatering in the number one cause of the houseplant
death. But be sure not to underwater, either. - Don't water on the fixed schedule, get to know
your plant's needs instead. Most plants only need watering
when the top 1/2"of potting mix is try. gently poke your
finger into the soil to test it. Some experience gardeners
go by weight of the pot - a very light pot will have a dry
mix. - Aim to make the potting mix moist, but not wet.
Most plants hate sitting in soggy potting mix, so always
let excess water drain away. - Potting mix in terra cotta pots dries out more
quickly than that in plastic or ceramic pots,
because terra cotta is a porous material. - Most plants need less water in winter because
they are not actively growing and need this period of
winter rest. However some plants are winter bloomers and they may
need regular watering providing bright light to produce
flowers, for example clerodendrums.

Cassia vs Bauhinia: which is better as an everblooming container tree?
Cassia vs Bauhinia: which is better as an everblooming container tree?
🌈 Cassia vs Bauhinia: which is better as an everblooming container tree?
🌸 Cassia (Senna) trees are very popular flowering trees - fast growing, free-flowering, relatively cold hardy, and they love the summer heat. Cassias come in several colors: yellow, orange, pink, red, and rainbow. Rainbow varieties (which are hybrids between yellow and pink cassias) are the most popular thanks to their multicolor blooms with swirls of yellow, pink, red, and orange. But while Rainbow Cassia is a spectacular flowering tree for southern gardens, is it a good choice for a container when you want color on your patio or pool deck?
🌸 Some yellow-flowering cassias make attractive bushes that bloom most of the year and stay compact, so they can be grown as container specimens: Cassia didymobotrya- Popcorn Cassia Senna alata- Empress Candles Cassia fistula- Golden Shower (a compact size winter blooming tree)
🌸 When it comes to Rainbow or pink cassias such as Cassia javanica - Apple Blossom Tree or Cassia grandis- Red Cassia and other species and hybrids (Cassia marginata - Rainbow Shower Tree, Cassia roxburghii - Ceylon Senna, Cassia x nodosa - Pink Shower), these are usually more vigorous trees that may take several years to bloom. Their flowering season lasts from a few weeks to a couple of months. These trees grow moderately fast but typically need to reach about 10 feet before they start flowering.
🌸 So, the answer is: if you want rich, deep color year-round from a container tree, go with Bauhinias - Orchid Trees. Most varieties grow well in pots, stay compact, and reach blooming maturity within just one season. The following varieties are everblooming and can produce flowers for up to 10 months of the year:
Bauhinia madagascariensis - Red Dwarf Orchid Tree. Blooms from winter through fall, up to 10 months a year. The most cold-hardy of all. Bauhinia blakeana - Hong Kong Orchid Tree. A large tree in the ground, but compact in pots if trimmed. Grafted trees flower right away. Winter bloomer, cold hardy to light frost. Bauhinia tomentosa - Yellow Orchid Tree. Flowers from Winter through Summer, cold hardy to light frost. Bauhiniamonandra - Napoleon's Plume Orchid Tree. Almost everblooming with the longest flowering period (less cold hardy than the first three). Bauhinia acuminata - Dwarf White Orchid Tree. Blooms from summer through winter (also less cold hardy than the first three).

3D garden ideas. Q: Can you make my yard bigger and prevent it from freezing?
A:Yes, we can make your backyard bigger by adding a 3rd dimension - trees as a upper level, shrubs as a second level, vines in between, low growing perennials below them. Add ground covers and potted plants as separate specimens in between in-ground planted trees and shrubs. One more separate dimension is orchids and other epiphytes that happily grow on the trees. This multi-level structure will allow you not only collect so many plants, but also maintain them in a natural environment, similar to how they grow in a wild.
As far as preventing from freezing - it depends. You can use greenhouse, cover plants, create microclimate under large canopies, etc. Some tropical plants are tolerant to light frost, once established. If it gets below freezing in your area for more than a few hours, and especially if you have numerous nights with frost throughout winter, we recommend to keep plants in pots (BTW, this way you save space and can collect even more!). Pots can be moved to protected area during cold nights. The more established the tree, the more chances to survive colder temperatures. You may also use propane heaters during cold nights.
We also use plant booster SUNSHINE boosters to increase plants cold tolerance.
Cold protection is a lengthy subject. Here is some more information on cold protection.
Also, we recommend to check out our magazine Tropical Treasures (about pushing the limits of tropical gardening) for a detailed article on cold protection.

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.
