The Q&A Archives: Buds That Dry Up And Not Bloom On An Hisbiscus

Question: I baby all my hibiscus but one is still not blooming. It will bud but then turn light green and fall off the bush. It was on a south wall and I have moved it to a north wall and the same thing is happening. The others are doing well even though they face in different directions.

Many thanks,


Answer: Hibiscus have a reputation of being somewhat finicky. If you over-fertilize they won?t flower, and if pruned they may take months to bloom again. If you are doing everything right and the buds just keep dropping it may not be the hibiscus?s fault. Insects called thrips can damage the unopened buds. These pests may go undetected until considerable damage has occurred and the buds drop. Bud drop could also be caused by sudden fluctuations in temperature or allowing them to dry out too much. Nematodes can attack the root system reducing the plant's ability to take up water and nutrients. Finally, some varieties of hibiscus, especially doubles, are characterized by premature bud drop. Some varieties bloom well during one period of the year and consistently drop their buds at all other times. Now that you've moved your plant, give it some time to recover and become established. Given the same care as your other plants, it should perform as expected. Enjoy!
