Question lilacs


I moved in to my house with a large lilac bush 2 year ago. I trimmed (after it had flowered). But, the flowers haven't returned for the 2nd spring now. I have another large flowering bush which I trimmed at the same time and it has returned to flowering greatly this spring. I don't know the exact name of the one that IS flowering except the flowers are like big snowballs.
Any ideas on why the lilac isn't flowering yet?

The best way to prune a lilac is to cut the oldest stems to the ground if it needs refreshing. It can take the new shoots 3 to 5 years to bloom. Another way to 'trim' is to cut off the spent blooms.

Often lilacs won't bloom because they like a more alkaline soil. Sprinkle lime around the base of the shrub now and next spring. Then do it every couple of years. Get your nose ready!!
