Question
I have cuttings from a lilic bush my mom had in Whittier, CA (L.A. area) I live in north eastern Colorado now & want to pot the cuttings if I can - to transplant into my yard in the spring. What should I do so the cuttings will root successfully? Thank you for your time & your help!  

Answer
Sorry to see this question so late, Dana, but I am just learning about the "experts pool" here.

Lilac cuttings are VERY hard to do successfully -- but it is still possible.  If you are able to bottom warm the rooting container, you increase your chances.  The stem must be cut at a slant, and the cutting must not be woody -- newer growth is easier.  Next autumn would be a good time to learn layering of wood perennials to product another specimen -- you cut, cover all winter with peat moss, then in the spring you have roots for a baby Lilac.

I hope your cutting(s) went well this winter.  If not, keep in touch and I'll describe the layering technique.  Meantime, let me know if you have any questions.
