Bundle up Houston!
Here are a few examples of tender plants:
- Citrus trees & edibles
- Elephant Ear
- Palms & Tropical varieties
Bring Potted Plants Indoors:
Gather your plants that are in pots or hanging planters and bring them indoors. The soil within is not sufficint to generate enough warmth to ensure their survival during a freeze.
Wrap your citrus or other fruit bearing trees with burlap or tree wrap, and secure it with rope or bungee cords. The thinner bark of fruit bearing trees can crack when the temperatures experience extreme fluctuations. Wrapping them like this will help to prevent them from "frost crack".
Cover the root ball of your palms with mulch to provide insulation. Then wrap the center spear and the first 3-6 fronds with water pipe insulation. If you don't have any available, pool noodles left over from the summer will work. Fold over the tops of the insulation to prevent excess water from being trapped between the insulating layer and your plant. Secure your wrap with tape.
The Morning After:
Remove all coverings and wraps first thing tomorrow moring, after the remaining frost has thawed. Failing to do this early in the morning could lead to future plant damage in two ways. First, during periods of continual freezing temperatures, the buildup of condensation within the covering or wrap could freeze, causing damage to your plants. Secondly, the insulated heat during the day could cause your plants to break thier dormancy, which would trigger an out of season active growth period. This would leave them more vulnerable, as the energy they contain would be diverted from storage to growth and would leave them more susceptible to frost damage in the future.
We here at Mike Ball Irrigation hope that this will help you prepare for not only tonights freeze, but for any freezes we anticipate in the coming months. Stay warm Houston!
