Japanese Lilac Tree

How do I get a Japanese Lilac tree to bloom? I live in Zone 5-6. It’s been at least 5 years since I planted the tree. It was a small fingerling from a catalog.

Here are various reasons why lilacs won't bloom, which may help, though the likely cause is a lack of phosphorus in the soil: https://www.gardeningknowhow.com/ornamental/shrubs/lilac/lilac-bush-not-blooming.htm

Need Info on Japanese Lilac Tree

Does this tree have large roots that are drawn to water, how far from house foundation should it be planted, and is it messy in the fall as leaves fall?

You will need to give this tree plenty of room as it will grow large.

Japanese Lilac Tree Flowering

Not turning white but stays green and falls off. Multiple flowers not becoming a tree flower. 15 years old and flowered last year.

Make sure your Lilac is receiving adequate water.
Water stresses can cause leaves and flowers to drop.
Pruning can rejuvenate a lilac and stimulate flowering the next spring.

Beautiful Japanese Lilac

I have a beautiful Japanese lilac. Do I have to cut the dead flowers after they are done blooming? My tree is very healthy. Last year I hardly got any blooms on it. Was wondering if it was because I didn’t trim the dead flowers. However, this year I have lots of blooms on it.

ANSWERS

Yes you can prune off the spent blossoms as needed.
Usually pruning can be done after the the plant is done blooming so if you don't dead head, this would take care of the old flowers.

Two Trunk Japanese Lilac

On a 2-trunk 3-year-old Japanese lilac tree, does it matter which one is cut to make a single trunk? I planted two mail order root Japanese lilac trees. Two years later one has a single trunk the other 2 trunks. Does it matter which trunk is pruned (equal diameter) and how close to ground?

ANSWERS

I would wait until the tree is dormant to prune.
I would leave 1 to 2 inches of trunk. You may have sucker growth in the spring and would want to trim those away as soon as they grow.

How Fast Does Japanese Lilac Tree Grow?

I would like to plant a Japanese lilac tree for privacy in a neighboring garden. Soil is light and I live the northern Minneapolis suburb in Minnesota. I think that my zone is 3.

ANSWERS

The Japanese Lilac is hardy down to zone 3. It has a medium growth rate. This is a great tree to enjoy in the spring when nothing else is blooming in our gardens.
I also garden in MN and you are zone 4a or 4b.

Here is a great link.
