Answer: Plant maturity, adequate sunshine and pruning at the right time of the year will all encourage your lilac to bloom. Some lilacs can take up to 7 years to establish and mature before they are ready to bloom. While you are waiting, withhold fertilizer (too much nitrogen can result in lots of lush green growth at the expense of flowers). Lilacs spend the summer developing flower buds for the following spring's floral display so you will want to prune it in June of each year, just as if it were flowering right on time. Prune everything back by a few inches to promote lots of new growth. With any luck, your plant will also develop flower buds - but you won't know until next spring. Best wishes with our lilac!
