To keep your lilacs looking their best, they need to be pruned, fertilized and shaped almost every year, soon after they are done blooming in the late spring.
In streamside or riparian areas, choosing the right plants and where to plant them depends on location in relation to the streambed. There are three zones that dictate the kinds of plants that can be grown.
Q: I have a California lilac tree in my back yard. A thick root is underneath the pavers and lifting them up. Will I kill the tree if I cut out that root? I sure don’t want to kill it!
