The Q&A Archives: Lilac Bushes

Question: I recently relocated from the SF Bay Area, CA to Las Vegas, NV. I have two potted 6ft. plus lilac bushes. Only one has flowered this spring and last spring. I would love to have full, healthy, lush bushes. At this point my plants are very leggy and sparse. Any suggestions from you would be greatly appreciated. Thanks very much.

Kind regards,

Susan DeKoster

Answer: Lilacs can become leggy if they aren't regularly pruned. Wait until after they have finished flowering and then reduce the size of each shrub by about one-third. This will promote lots of new growth to help them fill out and should provide healthy new stems on which flower buds can develop for next year's flower display.
