Fertilizer for flowers
I have two potted hibiscus that have bloomed beautifully the past number of months. They are getting kind of of skimpy or thin, and I'm thinking they need fertilizer. What kind should I use?

If your hibiscus are kept indoors year-round or are outdoors now, you can fertilize based on these guidelines for tropical hibiscus:
If your hibiscus plants are indoors for the winter and they are usually outdoor plants, it's best not to fertilize now. The issue in this case is usually the lower light levels, so giving them more light, such as with a grow light, should help them fill out. Wait until spring, then fertilize.
