Some plants grow so much that the question arises as to how to get rid of the growth.
There are several methods that will certainly appeal to site owners.
How to get rid of undergrowth
Some herbaceous plants can grow as well as the ubiquitous weeds.

In such cases, artificially defining the borders of the flowerbed helps. For example, before planting cereals with strongly growing roots, they are planted in containers and dug in.
As for ornamental shrubs like lilacs and rose hips, you need to think in advance about root limiters, which need to be dug into the ground to a depth of at least half a meter.
Slate or some other durable material would be best.
As for raspberries and blackberries, the constantly growing shoots thicken the bushes and weaken the main plant. Therefore, it is recommended to take care of this during the planting process and make barriers with a diameter of 40-50 cm and a depth of 35-45 cm.
