Just got these in early March. One bloomed right away, but now something looks like it's been eating the plant and it's dying. The other five are doing fine. What could be happening?
It is likely slugs. This article will help:
In last winter's snow, many of our fruit trees and an abutilon had bark nibbled off by hungry animals. In most cases this barking girdled the trees. Usually there was protection around the trees up to a height of about 15 inches: the barking was above this height and continued upwards for up to a foot, much more in the case of the abutilon. The abutilon looks sick but not dead. It has produced some new leaves. The fruit trees are astonishing, a mass of blossoms and looking very healthy. Are they really dying? If not, is there something I should do (eg. paint their barkless bits with Arbrex or such)?
There is a chance that the animals did not chew all the way through the cambium. If the cambium is intact, the trees have a chance and judging from you description, I would say at least with the fruit trees this may be the case. i would cover the wounds with a paper wrap protection (sold at nurseries) or something else temporary. Do not cover it with a permanent tar or other permanent substance as this can trap disease against the wound and hurt the tree.

I live in Vancouver, WA, and the temp is supposed to drop below freezing in the next 2 days. I have two 8 ft. Abutilon that I'd like to winter over in the garage. Will they go dormant without light, or do they have to come in the house by windows?
If you have room inside, they'll probably do better indoors in some light. They will do well in a cool place protected from freezing temps, but you should add some extra light. You'll probably want to cut them back some; however, if you cut too much, you'll lose some flowers next spring.

I have a salmon variegated abutilon that is so badly shaped I'm hoping I can get a do-over by pollarding it. I realize there are no guarantees, but do you think this action will kill it? Should I root some cuttings first, as insurance?
Abutilon do have a tendency to become leggy and regular pruning can help maintain a nicer shade.
Pruning should be done in late winter or early spring.
You can remove or cut back up to 1/3 of each branch, or the plant overall.
Make the cuts just above a node.
You can tip prune the branches when they have at least 6 leaves appear.
You can propagate these tip cuttings.

I live in zone 9 Central Florida. My flowering maple is planted outdoors, was a small specimen but is now about 7' tall. Should I wait until spring to cut it back or is it OK to do it now? Please send care instructions. . . Thanks!
Maintain the plants shape with pinch pruning, do this to maintain shape.
Overly pruning the plant can reduce flowering.
Do not shear the plant like a hedge.
