So keep him in check (Syringa)

Are there lilacs without runners?

The bad news first: there aren't any Lilac varietiesthat forego the formation of runners. However, there are ways to prevent this, for example by grafting a noble lilac variety on a base that does not sprout root shoots. This is the case, for example, with lilacs grafted on privet - these drift at most above the Refinement point, which is why it must not be in the ground - but always just barely about that. Usually, however, noble lilacs are refined to their wild forms, which in turn sprout busily.

Combat root runners effectively

In order to counteract an uncontrolled reproduction of the sprouting lilac, only two things help: the installation of an effective one Root lock already during planting and the consistent removal of runners.

Installation of a root barrier

The most effective way to prevent unpleasant mini lilacs is to bury a suitable one

Root lock already when planting the lilac. Many a gardener now comes up with the idea of ​​using pond liner for this purpose: This is not enough, as the strong lilac roots simply pierce the liner. Instead, special root barriers for bamboo have proven effective, but also the method of simply planting the lilac together with a large clay or ceramic pot without a soil. It is important that the barrier extends deep enough into the ground - many a lilac has already undergone concrete foundations 80 centimeters deep.

Consistently remove runners

It is also important to consistently remove runners. It is not enough to just cut them off on the surface or run over them with the lawnmower. The consequence of this is simply that the lilac tries to drive out even harder. Instead, you have to dig up each individual runners and cut them off right at the root neck. Also parting off with a good one spade is possible, moreover, more physically manageable.
