why dont my lilac tree flower ive had it 5 years nothing?

Answer 1

Lack of sunlight is a common problem. A minimum of six hours of direct sun is best for Lilac bloom production.

Too much nitrogen can create a problem. Often lilacs are planted in the lawn and fertilizers used to green up lawns are too high in nitrogen.

No bloom after the first year is another common problem. Lilacs purchased as bareroot or ball and burlapped plants need time (up to 3-5 years) to re-establish a complete root system. During this period the shrubs energy is directed to root development, not bloom production. Newly planted shrubs can bloom the 1st. year because the flower buds were formed before the shrub was harvested and placed in the garden center for sale. Containerized plants reflower quicker following transplanting.

Pruning at the wrong time often is another problem. Lilacs should be pruned after flowers have faded.

Finally, Lilacs are plants for colder climates and must have a dormancy period in order for them to flower. In warmer climates you can activate the equivalent dormancy by depriving the lilacs of water thus forcing them into dormancy. Once water is reintroduced a few weeks later new growth will begin and stimulate the flower buds to flower.

You can sometimes force a Lilac to set blooms. Use a square shovel to prune the roots in six locations out at the edge of the drip line. This creates a mild shock to the plant & can stimulate flower bud development.

Here are some tips about lilacs:

1- They need a good amount of sun, but they can withstand a little shade;

2 - They like a slightly basic soil (alkaline or high pH number), though mine flower pretty well in New England acid soil;

3 - They are really happy with not much fertilizer; A good 10-10-10 right after flowering is enough.

4 - They should not be pruned in the laste summer after next year's flower and leaf buds form! Flowers for spring, 2008 have already been formed by now in 2007 flower buds. (Isuspect pruningtoo late in the growing season is probably your problem.)

5 - They are actually pretty winter-hardy

6 - Lilacs actually seem to thrive on neglect. Deadheading old flowers isn'tactually really necessary, it just makes the plant look neater and more tidy, and will probably result in a more even bloom if you do this regularly over the years.

Answer 3

The only thing I can think of is that it is not getting enough sun. Lilac are full sun plants and if in the shade or not getting enough sun then they will not bloom. Also, another thing to remember is that if you let your lilac seed then it will not produce many blooms next season so you need to dead head the spent blooms to promote a larger bloom later. However, not dead heading would not cause it to not bloom at all.

Answer 4

My Dad had one in his garden which didn't flower and my Gran (his Mum) advised him to put used tea leaves round the base every time he made a pot of tea. He did this, and the following year and every year after he got loads of beautiful flowers. I don't know the technical name is for what the soil was lacking, or why this worked, but thought I'd suggest it because it certainly worked for Dad.
