The Q&A Archives: yellowing buds

Question: Buds form on the Lady Baltimore rose mallow purchased in August 2005 but then they yellow and fall off. What can I do to prevent this.


Answer: There are two potential reasons - overwatering will turn the buds yellow and they will fail to open, and bud worms can attack the buds, feed on the unopened flower and cause the sepals to yellow and die. Try picking off a few of the yellowed flower buds and breaking them open. If the bud is empty, suspect bud worms; if the bud is filled with immature petals, suspect overwatering.
