Question: My hibiscus looks pretty healthy. But the healthy-looking buds keep drying up and falling off. It's got lots of buds, but no blooms. What am I supposed to do?
NICK: When you have a series of buds that don't open, the first thing I think about is to do a little investigative reporting. I want you to open up the bud, and with the magnifying glass, see what's inside, because it's probably a minute insect called a mite. Sometimes mites will make a little webbing, and with others, they don't. Now that you've identified it as a mite, you're going to have to come in there and spray this thing with a miticide that you would get at your local nursery and garden center. Then fertilize the plant, and you should be just fine.
