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.

☘️ What plants are easy to ship in Winter?

Ordering plants in winter is often easier than people expect - and for many plants, it is actually better. Lush foliage plants like philodendrons and medinilla, fine-leaved trees such as moringa, jacaranda, and poinciana, and even sensitive fruit trees like papaya, jackfruit or starfruit ship more safely in cool weather without overheating stress.

Winter is also ideal for subtropical and cold-tolerant plants, dormant or deciduous plants like plumeria and adenium, orchids - including ground orchids and vanilla orchids, and winter bloomers that flower their best right now. Winter care is simple: water less, use gentle liquid amino-acid fertilizers like Sunshine Boosters, and monitor insects.

In mild climates, many tropicals can be planted anytime, while extra-tender plants can stay potted until spring. Winter is a perfect time to bring tropical warmth indoors and enjoy greenery when you need it most.

🍲 Where the Garden Becomes the Kitchen

Biquinho pepper loaded with fruit - small, beak-shaped peppers ripen from green to bright red, offering intense fruity habanero flavor with little to no heat on a compact, heavy-producing plant.

A lot of plants that thrive in Florida heat have deep roots in Mexico, and not just as ornamentals. Think coral vine or flame vine climbing a fence in summer, or bird of paradise sitting at the edge of a patio like it owns the place. These are not plants that need coaxing. They grow fast, full, and unapologetically. Then there are the plants you actually eat: peppers, prickly pear , sweetleaf, and fruit trees like avocado, guava, and sapodilla. They do not just decorate the yard. They change how the yard works, and how the kitchen feels all year.

That is the part that sneaks up on you. Gardening stops being about having a pretty yard and starts becoming a way of living. Mango tacos taste different when you picked the mango yourself. Everything does.

🍀Mexican Plants That Thrive With Minimal Effort

by Tatiana Anderson, Top Tropicals Garden Expert

Lippia dulcis - Aztec Sweet Herb in bloom - a low-growing Mexican herb with tiny white flowers and remarkably sweet leaves that can be eaten fresh or added to fruit dishes, traditionally used since Aztec times for coughs and colds.

These Mexican plants are surprisingly easy to grow if you give them what they expect: sun, heat, and good drainage. Most of them are built for tough conditions and will grow fast with minimal care once established.

The one rule that matters: fill the planting hole with water. If it does not drain in 5-10 seconds, plant on a mound or use a container.

Flowering vines will take off quickly, edibles like peppers and sweetleaf lippia are very forgiving, and cactus types prefer to be left alone rather than overwatered.
