The flower buds on my hibiscus and gardenia plant drop before they open. What could the problem be?
Bud drop is often a problem with both of these plants and can indicate an insect problem, cultural/environmental problem, or a characteristic of that variety. Insects called thrips can damage the unopened bud. These may go undetected until considerable damage has occurred and the buds drop. See Insect Management Suggestions. Too much or too little fertilizer and/or water can stress the plant resulting in bud drop. Nematodes can attack the root system reducing the plant’s ability to take up water and nutrients. 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.
