    I trim out the branches that are weak, and old, and then this makes room for the new shoots, or sprouts in the spring. Also, in the fall I trim my Rose of Sharon, and this helps a great deal in the spring, for more growth, and a thicker growth. Take care, J.

    Only clip out about a third of the bush a year or you could put it in shock.

    Also, if you are pruning out a lot of really old wood, be prepared to do lots of tool sharpening. Lilac wood is very hard!

    As a trained master gardener, always cut off at the ground the LARGEST of the "trunks". I take mine out about every other year or three. Also it is much better if you take the time and WORK to cut off all the old blooms shortly after they die and dry up. I NEVER "prune" the other main trunks. Just take out the largest. I use a chain saw, right at the ground. or if it is really crowded, I have a saber saw but it is MUCH slower.

    cut out the thick branches and leave the rest.
