I have three Hibiscus plants that were beautiful when I got them, but now the leaves are turning yellow. Am I watering them too much? Every day I break off yellow leaves some days as much as 12 leaves. Thank you.
The soil should be moist, but never soggy. When the top inch or so of soil dries out, then watering again--throughly.
Make sure you water so the entire root ball is watered and excess water drains from the container.
On warm dry days, you may need to water twice a day.
Yellowing leaves can be caused by a few other things, so the article below will help you.
