WHAT'S HAPPENING IN MY LANDSCAPE?
Just as we close one year and start the next, the temperature outdoors nose dives into the mid- thirties in New Orleans. You might start asking yourself, are you suppose to cover your plants? Will my citrus survive? What should I do once it warms up?
Here is where you start.
Protecting Plants
When the local weather forecaster instructs everyone to protect their plants, exactly what are you suppose to do? What gets covered and what is the best way to do so?
Covering plants for frost truly requires a 2 layer system. A fleece/cloth type fabric needs to be placed over the entire plant and secure the cloth/fleece with twine or cord. Then place an outer layer of thick plastic and secure with twine or cord. This method will make sure that the outer layer of plastic does not touch the foliage directly.
If you use a single layer of plastic, the plastic rest directly on the foliage causing the foliage to wilt. In addition to the foliage wilting, often a single layer of protection doesn't provide a "greenhouse effect" and the plant materials dies.
