As usual when you put in some work, you get results. I have new growth on several of my plants, my avocado and jades seem to have especially appreciated last week's attention. When a jade has nice plump leaves, you can take one off and use it to propogate a new plant. I'll take pictures and show the how-to in a later post.
A quick way to spruce up a plant with long, thin leaves uses regular house scissors. I cut off the brown edges and tips, cutting on an angle. With a palm, for instance, I hold the leaf and cut the tips off one whole side at a time. This keeps the line of the leaf correct, and makes it look better instantly.
