1. Lilac Transplanting

Asked by Anonymous - November 7, 2010

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?

2. 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?

3. Lilac Tree Roots

Asked by Anonymous - January 25, 2011

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?

Answers
  • 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.

4. Trimming of Lilac

Asked by Anonymous - January 26, 2011

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.

Answers
  • 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.

5. White Substance on Branches of Lilac Bush

Asked by flowergarden - March 3, 2011

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.
