The Saturday forecast is rough in Tampa and likely elsewhere in central Florida where we push the limits of tropicals growing a bit too far near the freeze lines.
The bleakness is here:
It’s not going to frost because it’s going to be windy. Winds are 15-20mph with, holy crap, 40mph gusts. This complicates the “covering your plants” issue. Why? If the complete covering to the ground cover blows off, you are screwed. Thankfully, it’s not going to rain. Whew!
Here’s the salient point. If the *duration* of freezing hours passes four hours straight, tropical plants will suffer or die if that cover is not tight and complete in which to trap in the earth’s radiant heat. Light bulb (incandescent ones) under the cover help a lot: but don’t be sloppy and start a fire if the wind blows your cover all over the place.
Bring all potted tropicals inside. Any potted tropical is in a pot and not in the ground, and those roots are exposed to freezing air. The potted tropicals are far more vulnerable.
If you have one or two hours of predicted freeze hours, then you might luck out. But if your area is gonna have more than four consecutive hours of freezing temperatures, we’ll then. Get ready and prepare now.
Some say, “Holy crap, my tropical plant has grown too big to cover.” Well, you might consider cutting it way back so you can cover it well. But do this too. Shove a light bulb in there too. Why? You cut back the plant: it doesn’t have outgassing leaves to help create heat. It’s only relying on the earth’s heat rising. But please be careful. Windy weather tears apart the tents we make easily.
Get out your thermal blankets, old comforters, old duvets and multiple layered sheets. Have plenty of clothes pins, clamps, stakes and rocks to create a good ground to ground cover.
Plastic? Maybe.
Only plastic as the outer layer of cloth material. The plastic should not touch the plant.
I hate cold weather because I get dozens of last minute calls as to: “Will this freeze, Brian? What do I do? How do I protect them?
Best wishes to all.
