I planted a Hybiscus after Christmas. It had lots of buds which have bloomed but the leaves are all turning yellow. I am afraid that I am going to loose it. What can I do?

Hibiscus usually thrives in the desert so yours is not acting as it should! It is normal for the oldest leaves, those lower down and near the center of the plant to turn yellow and drop. These are quickly replaced by healthy new leaves. However, if all the leaves are turning yellow, it could be weather related. Our cold, wet winter might be to blame, especially if the planting site does not drain well. Soggy soils can suffocate roots. It might be that you need to dig the plant, amend the soil with organic matter to help it drain a little better, and then replant. Another problem we have here in the desert is alkaline soils. Sometimes plants need a dose of iron (such as Ironite) to help them green up. You can try some Ironite in amounts as listed on the package, which vary according to plant size, if the leaves are pale but the veins in the leaves are bright green. I hope this information helps you determine just what's causing the yellowing leaves. Best wishes with your hibiscus.
