We just bought a home that has about 12 Hibiscus plants. They were very healthy when we moved in August. Now one plant has died and the others are looking very sickly, leaves turning yellow and deteriorating quickly. There are some holes in some of the leaves like something is eating on them but never see anything on them. Any idea on what is causing this and what I should do to correct the issue before they all die?

There may be a pest problem. Check the plants closely as some pests can be small. Treating them wtih neem oil often helps. It's safe for eliminating most insect pests and is a great fungicide as well.
