Something is eating the leaves of 4 of my outside hibiscus plants. What should I do?
It is possible that it is slugs. They will climb small trees at night to eat the first foliage they come across. You may want to try Diatomaceous Earth around the base of the tree. It will kill any bugs or slugs that crawl across it. This article will also helpwith slug control:

Have a Hibiscus plant outside that has been great and producing good orange flowers until recently. Fertilize it monthly with Miracle Grow. Noticed a white power substance on flowers and branches. Flowers are small. Blasted off white power with hose. Flowers look better but white powder re-occurs. What is white powder? And what should I do?
The white powder you mention sounds like powdery mildew. Neem oil can help with this fungal issue. Here are some articles that you may find helpful: https://www.gardeningknowhow.com/plant-problems/disease/powdery-mildew-homemade-and-organic-remedies.htm

Why are the leaves on my hibiscus tree turning yellow? My hibiscus doesn't appear to have an insect problem, and I have not yet fertilized it, so over fertilization isn't the problem. It receives full sun and adequate water. I live in the Upper Peninsula of Michigan and for the most part, we have been having very warm weather (80's-90's) during the day and cool evenings. Is it possible that spraying the leaves and watering with cold hose water could be the cause of yellowing leaves? GardeningVixen
