Monster lilac - retaining wall problem
Comments (4)I don't know if it's the lilac impacting your retaining wall - looks like failure due to the ground heaving, shifting, and settling. Not a mason, but would think freezing and thawing (or a bad mortar mix) could cause mortar to pop. And now that it's underway, it'll continue with or without the lilac. The root system is probably fairly extensive if you're getting suckers ten feet away. If you want to get rid of it, dig around it in a circle, chopping off the roots as you go. Labor intensive, but doable. Then paint the fresh root cuts with a non-selective herbicide like RoundUp or some other stump killer type product. Or, have it it professionally taken out and the stump ground. You might still get a sucker or two, but since they'd no longer be attached to the parent, mowing over or ripping them out should take care of them. I have many, many, many feet of old and huge common lilacs -and I've never seen a sucker more than 6" from the parent plant. But I concede different varieties do different things. And I kind of welcome the close in suckering since it replenishes any old wood I might lose. There are wall and tree/shrub experts on the forum; hopefully they'll chime in....See MoreHelp Pruning an Older Lilac Bush into a Lilac Tree

Comments (7)Syringa reticulata and Syringa pekinensis have both been available in the United States since the late 1800s. I have personally managed individuals from the turn of the century (early 1900s). These plants can be grown as multi-stemmed or single-stemmed small trees. That is a choice made by nurserymen growing the plant originally, and afterward by the party responsible for the landscape in which the tree is planted. There are a number of narrow selections of Syringa reticulata - 'Ivory Silk' is a popular and very common one. 'Ivory Tower' is another. These will have smoother gray bark. Syringa pekinensis is more variable in bark and form. A selection named 'China Snow' has fabulously exfoliating/peeling bark, competing with some of the ornamental cherries. It doesn't seem to have as heavy a flower display as many of the Japanese Tree Lilac clones. Bernheim has a collection of old specimens dating to the 1960s here in KY. These are durable plants, and ought to be used more widely....See MoreCOLLECTION: Japanese Lilac - Foxglove Tree - Tulip Tree
