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.

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! ;)
