How do I protect my Hybiscus plants from frost?

Emily, would not let the plant get down if possible to the frost temps. If the plant is potted bring it inside out of the cold. https://plantcaretoday.com/how-to-care-for-a-potted-hibiscus-tree.html

First off are they tropical hibiscus or perennial ? What is your location?

You can also use saren wrap to cover them when it's not so cold, it lets light in but protects them from the cold.

I am in North Carolina, Region 7. If it is a perennial as mine is, I cut it all the way down to about 4-5 inches from the ground and VOILA! it blooms well every year. As a matter of fact more and more white blooms every year! I had a tropical one but it did not last through the winter so . . . Abundant blessings on your gardening attempts . . . Merry Christmas!

Thank you!

Do not wrap in plastic, it will cause rot from the moisture it holds in. Use cloth only.

A part of my back yard there is English Ivy growing . It is climbing the trees and killing them, I need to know how I kill it. I mow as much as I can and try to cover it with recycled mulch but it keeps coming back. Please help.

I have had luck painting on the Roundup instead of spraying for more control, especially if other plants are in the area.
