Hi, I'm Stan DeFreitas, Mr. Green Thumb for On Gardening. When we talk about flowering plants, often we have some problems. This is a beautiful hibiscus of course, but hibiscus have occasionally some bad leaves. And you can see the contrast we have here where you've got some good leaves and bad leaves. See those nice, beautiful dark green foliage, well underneath there we've got some bad leaves and we might just call it senility in the leaf. And that just means old leaves drop, new leaves come on. Now occasionally you may have some aphids or you may have some mites that are causing trouble, the first rule of thumb is to go in here on the plant and just kind of trim out the bad looking leaf. Grab the leaf, take it back down near the pedial, and just sort of cut it off and make it come along. Take that leave, take it off of there, and that's the easiest thing to do to get rid of the bad looking leaf. Now if you're seeing a lot of aphids on here, you might try something like neme oil or maybe some soaps. If you have to spray, be careful with hibiscus. Many of our plants get into phytotoxicity. Big word means burn your plant. So use something that's safe, something organic if you can, and you should have good results. For On Gardening, I'm Stan DeFreitas, Mr. Green Thumb.
