A miss Kim lilac tree was staked and I never loosened the tie which caused a lump under the lower branches. What harm has it caused as I notice many dead branches.As it is one of pair (4 ft tall) I am concerned I can find one of a similar size. Live in bucks county Pa.Tony DiMinno adm@comcast.net
If the tie has bee removed and they is new growth above the pinch point, there is a good chance it will recover. You can increase the chances of recovery but diluting some soluble food like Miracle-Gro in a watering can and washing it down over the leaves and stems of the lilac. Soluble food can be absorbed directly into the plant as an emergence feeding. Do this every week or so but stop when temperature starst getting above 75° F
