What is the lifespan of a Japanese lilac tree?
The Japanese Tree Lilac, a native to Northern Japan, is larger than the traditional lilacs and is the only Lilac that grows a tree-like form and size as it grows up to 30′ tall with a 20′ – 25′ spread. Its lifespan is about 40-50 years which may not seem longlived in the world of trees. Lilacs should be pruned yearly to develop a good framework of stems and promote vigorous growth that enhances flowering. Yearly pruning consists of cutting diseased, misshapen, and unproductive stems to the ground.Lilac problems Suckers may spring from the base of the plant. If you don’t want to propagate from them, tear or wrench (rather than cut) the shoots away. This can be done from midsummer onwards and will help to prevent them regrowing.Fertilize in spring with a general-purpose organic or conventional fertilizer, and thin overhead tree branches to ensure plenty of sunlight — a key factor for healthy lilac blooms. To keep lilacs looking their best, prune, fertilize and shape them almost every year — soon after they finish blooming in late spring.How To Plant And Care For Lilacs. Lilacs grow best in full sun and well-drained soil. Lilacs grown in partial sun or shade will not flower well.

Where not to plant lilacs?
Though lilacs are very cold tolerant, they do not do well in hot areas. Even if the plant itself survives, it will bloom little if at all, because the plant needs exposure to cold temperatures, called “chilling,” in order to develop its flower buds. Lilac plants do not need a lot of fertilizer. We recommend fertilizing your plant after the second year of planting. To promote blooming, fertilize your plant in the early spring with a general purpose 10-10-10 fertilizer.Another trick to speed up flowering is using Epsom salt once per month on your lilac plant. Fill a bucket with a gallon of water, and stir in two ounces of Epsom salts. Pour this solution onto the plants.

The next best time to plant is in early spring after the ground thaws.Best Plants To Grow With Lilac Underplanting lilacs with spring and early summer bulbs is an effective way to create a colorful display to begin the growing season.

Are lilacs high maintenance?
Once established, lilacs are fairly drought tolerant and require minimal care. Plant them in a place where you can enjoy the fragrant spring blossoms. Lilacs bloom on the previous season’s growth and develop next year’s buds shortly after blooming in the spring. Pruning needs to be done at the same time that the spent flowers are removed within a couple of weeks after the plant blooms so that next year’s buds are not removed.Lilac flowers last for about two weeks once they bloom. However, the plants themselves are quite long-lived, with some lilac shrubs living for over 100 years. Regular pruning helps extend the lifespan and improve the health of these plants.Some people believe that deadheading lilac will lead to better blooming the following year, but this is simply not the case. Whether you deadhead or not, flowering the following year will not be affected, so deadheading is usually for your own benefit, rather than for the plant.As a general rule for all lilacs, they should be pruned immediately after they’re done flowering in the spring. Since lilacs set next year’s flower buds right after the current year’s flowers have faded, pruning later in the summer or fall will result in cutting off many or all of next year’s flowers.If you plant a sucker from another lilac tree, it takes 8 years to flower. A nursery plant will flower in a year. It certainly does not look like it is old enough to produce buds. Other reasons for not flowering include too little sun-they need full sun to bloom well.
