I bought this lilac bush 2 years ago and it had a few blooms. To date I have not seen another bloom. The bush looks healthy and is growing - it is about 6 feet tall now. What should I be doing to receive blooms?

When is the best time to prune my Josee Lilac bushes? Is fall alright?
The best rule of thumb on pruning lilacs is to do it right after the flowers die off in the summer. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/shrubs/lilac/pruning-lilac-bushes-when-to-trim-lilac-bushes.htm
I am getting ready to move from NJ to TN around the middle of October and I need to know if I can dig up my lilacs and take them with me when I move? Will I be able to transplant them?
Yes, you can. Fall is the most ideal time for transplanting. Just be sure to get as much of the roots and surrounding soil as possible and transplant in similar growing conditions for a greater chance of success. To reduce shock, trimming may help.

Is is possible to grow lilacs from seeds?
It is possible but this method will take longer to grow the shrub and years to produce flowering. A much better and easier way of propagating lilac is through cuttings. This article will help:

In addition, lilacs are typically clump forming, producing new shoots from the base of the trunk. These shoots can be used for propagating lilac bushes as well. Dig down from the main clump, exposing the roots and cut the shoot away from the mother plant. Make sure you include roots. Then simply plant the shoot in a suitable location, watering regularly until it takes hold.

You may have caterpillars eating some of the leaves. They are usually not an issue.

I planted a lilac shoot 2 years ago. How many years does it take to flower? Should I have pruned even though no flowers appeared? I live in Topeka, KS. It's at the NE corner of my house so after reading the article here, I think I should move it to get more sun. Thank you for any advice. Martha
Depending on the variety most will bloom after 3 or 4 years and some can take 6 to 7 years.

My lilac tree has cup-like shaped leaves and I would like to know what it is. I planted this tree this past spring. I purchased 2 lilac trees and only 1 is having these leaf problems. There is nothing else on the leaves, such as mildew or spots. Can you help? Thank you.
I have heard of the variety Miss Kim is quite sensitive to water conditions.
Either to dry or soggy roots effect this variety and will have cupped leaves followed by leaf drop.
That being said, to dry or to wet could effect any plant with leaf cupping along with yellowing leaves.
Aphids are another possible cause. They can be so small you can't really see them. If you suspect insects treating with Neem Oil is a good and safe treatment.
It is safe for people, pets and bees.
