As of right now, NOAA (our preferred source for weather forecasts) shows cold weather starting Sunday night (1/14) through Wednesday morning (1/17), with temperatures dipping below freezing Monday and Tuesday nights. That means we’re busy preparing to protect plants here at Gill’s! We want you to be prepared too – here’s how.
1. Water all plants well. It sounds counterintuitive, but watering will help keep the ground temperature warmer by filling tiny air pockets in the soil.
2. Cover cold-sensitive/tropical plants (like Dracenas, Ti plants, Crown of Thorns, Schefflera, Ixora) and tender new plants. Cold-tolerant plants that were recently planted in the ground (like trees, Boxwoods, Hawthorns, etc.) do not need to be covered, just watered well.
- Gather supplies now, but wait until Sunday afternoon/evening to cover your plants. Keep your eye on the weather – it could change!
- We have pre-cut frost blankets and frost protection cloth that can be cut to your desired shape, or you can use quilts, bedsheets, towels, etc.
- Make a tent to capture ground warmth. Wrapping plants like a lollipop will not be effective. Make your tent and use whatever you have to weigh down the edges, like anchor pins, bricks, firewood, garden hoses, rocks, etc. Remember – the most important thing is to capture ground warmth. The ground temperature will remain warmer than the air. Watch Wyatt’s demo video below!
- Consider cutting back tall shrubs. If you have taller shrubs like Esperanza that would be difficult or impossible to cover, consider cutting it back to a few feet tall so you can cover it.
3. Bring in potted plants. Since potted plants don’t have the advantage of retaining ground warmth, they are more susceptible to cold temps. Bring them into the house or garage if you can. If they are too big or heavy, water them well, lay them over on the ground, and cover the whole plant (pot and all) with the tent method.
We can’t cover all of the information about freeze protection here, but you can give us a call or stop by if you have questions. Follow us on Facebook and Instagram where we’ll continue to post how-to’s and updates.

How do you protect your bananas on a tall banana tree?
Jesse Jenkins says
Hi Betty – it would be very difficult to protect a tall banana tree unless you could build a tent over it. Go ahead and pick the bananas now. The good news is that the foliage may get knocked back by the freeze, but will grow back quickly.
Francy Miller says
I have about 10/12 Monarch caterpillars that I have been nurturing for about 10 days. They should be forming their chrysalis any time now. Question #1. They have just about exhausted the leaves on the plants provided for them. What short term recommendations do you have for feeding them. Question #2. I’m at Port A and what shall I do to prepare them for the cold coming in. # of the plants they are feeding on are in pots. I was going to cover them with a sheet and put a small string of Christmas lights under the cover to give them warmth.
Jesse Jenkins says
Hi Francy – bring the potted plants inside the house or garage. You can use zucchini spears to feed the butterflies short term.
