The Q&A Archives: Lilac bush

Question: Hi,I have a lilac bush for many years and it had only one flower 2 years ago.I got excited thinking this is the start.This year again nothing.What could be the problem?

Answer: Lilacs do best in full sun with an average to rich soil. The most common reasons for lack of bloom are insufficient sunlight and pruning at the wrong time of year. Lilacs bloom on wood that grew the year before, so do not prune them except in late spring right after the bloom period in your area. To encourage good growth you could apply compost and/or a complete granular fertilizer such as 10-10-10 in spring per the label instructions. Hope this information helps!
