Lilac Transplanting

I bought a yellow lilac bush this past spring and since it arrived early and I didn’t know where to put it, I planted it into a large pot on my patio. It’s done pretty well and is showing new buds as we speak (November). I live on Long Island, NY and it’s getting cold out. Since I’m still unsure where to plant it and didn’t think fall was a good time anyway, what should I do so that it survives the winter? Wrap it? Put it in the unheated garage? Bring it indoors? Leave it be?

Your unheated garage would be good, or near the foundation of the house with the pot buried in mulch. If you do put it in your garage, make sure to water it once a month or so to keep it alive.

Pruning Lilacs

When is the best time to prune a lilac bush? I planted a bush last spring that is about 2 feet tall. Should I prune it back some now (Nov in SC) to encourage blooms?

ANSWERS

You want to wait until right after it blooms to prune. Pruning now will cut away some of the growth that the blooms will flower on, which means that there will be fewer flowers.

Lilac Tree Roots

I have a lilac tree. It’s about 9-feet high.  I have it planted 6 feet from my neighbor’s wall.  They are worried the roots will damage their foundation. Can you tell me if this will do that?

It is highly unlikely that the lilac will cause damage to a foundation. They have very non-aggressive root systems and this is why you often see them used as foundation plants. The only way that it could be a threat (and even then, the plant would probably die before it did damage) would be if the roots were restricted tightly, as in there were only a few feet for the roots to grow in. That does not sound like the case where you are, so the lilac is not a threat.

Trimming of Lilac

My question is I have lilacs that are about 10 feet tall and I’m looking to cut about two feet off the tops. Can I do it now or even early spring? I live in NY and the temps are in the 30’s and 40’s when I’m looking to cut them.

Pruning them in early spring will not hurt the plant, but it will greatly reduce the amount of blooms you get this year. If this is not a concern, you can prune in early spring. Otherwise, wait until right after they bloom to prune them.

White Substance on Branches of Lilac Bush

What is the white substance (looks like a white power) on the bottom going toward the to of the branch.  Will it kill the lilac? What, if anything, can be done? Thanks for any help.

When is the best time to transplant a lilac bush?

ANSWERS

If you can transplant at any time, spring and early fall are the best times. To reduce shock, trimming may help. Dpending on its size, you can cut it back by 1/3 to help it recover from the move better, but if you remove all of the branches, the plant will take several years to bloom. This article will help when you transplant it: http://www.gardeningknowhow.com/plant-problems/enviromental/learn-how-to-avoid-and-repair-transplant-shock-in-plants.htm

Are lilac bushes/trees deer resistant? Are butterfly bushes deer resistant?

ANSWERS

For the most part, they are deer resistant. That being said, no matter what the plant, if a deer is very hungry, it will eat almost anything. This is why they say deer resistant rather than deer proof. Here is a link to a site with a list of deer resistant plants: http://www.humeseeds.com/deer.htm
