Lilacs bloom on the tips of the branches, and develop flower buds the summer prior to blooming. Be careful not to prune too late in the season or you might accidentally prune off the flower buds. Lilacs (except for the Descanso hybrids) require a pronounced winter chill to put on the most spectacular display. Make sure you lilac is one bred especially for your mild winter climate. Most lilacs do not need feeding. In fact, too much nitrogen fertilizer will result in lush green growth at the expense of flowers. Water as usual but don't feed or prune your lilac. If it is growing in a full sun site it should bloom for you next spring. Enjoy!
