Hibiscus Problem

Question

I am in charge of landscaping at my condo, which has a large brick plaza. We have many large pots with tree form hibiscus and potato vines. The hibiscus in one row of pots are struggling. . .the leaves are small and some are yellow and shedding. The others seem to be thriving. They are watered daily. Any ideas?

Answer 1

How often are they fertilized? If they are not fertilized at least once a month, this is most likely the issue. The other issue may be a pest problem. Check the plants closely as some pests can be small. This article may help: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/answers-to-what-causes-hibiscus-leaves-turning-yellow.htm
