If the Hibiscus and the Turk's Cap are hit by a good freeze (which pretty much everyone had last year) the vegetative growth will die back to the roots and re-sprout the following spring. If that happens everything gets cut back to the ground during a pleasant winter day. Both show up later than most plants in the spring so they need some time. If you have a deciduous Yaupon Holly it is normal for them to lose their foliage during the winter. Typically Yaupons are lifted to show off their multi-trunks

Here's a good one.

I have a question about pruning tomatos: I want to save one healthy tomato plant in a container for a fall crip. The plant is about 4 ft. tall right now. Where do I trim it?

You just may want to cut off the tops and re-plant them deep after pulling off most of its leaves. The tops seems to do better than trying to save the parent plant.

Thanks, Wally. That's exactly what I needed to know.
