|When is the best time to prune my lilac? In early spring? thanks - you guys are terrific!
|Lilacs bloom in the spring so wait until after your lilac has finished blooming and then prune it back. If you prune it in early spring, you'll be pruning off the flower buds before they have a chance to open. Lilacs develop flower buds for the following year's flower production during the summer months. These flower buds remain undeveloped until the springtime. Prune immediately after flowering has finished and your lilac bush will have all summer to develop flower buds for next spring's floral display. Hope this clarifies things for you - and thanks for the compliment!
