Question From: C. Thompson - Louisville, Kentucky, United States
Q: My knockout roses bloomed heavily, then I trimmed off old blooms, then noticed the new bloom shoots were falling off the plant before it bloomed the second time. There is no bugs noticable, no disease symtoms that I can find. The new shoot with the tiny rose bud just are falling off the stems. Do you have any ideas?
Could be bud worms. If you cut the buds open you may find a tiny worm inside. Thrips also cause bud drop. Best And Happy Yardening, Nancy
