You no longer have to run around the area with a shovel.
Every summer resident whose plot allows it grows raspberries, because it is a healthy berry.
But there is one downside. Raspberries do not like to stay within the boundaries of the plot allocated to them by the gardener.
The plant regularly produces young shoots, which may end up in a tomato bed if they grow 1-2 m from the raspberry patch.
This is a labor-intensive process. But it will allow you to close this issue once and for all. Sheets of slate or metal will stop young shoots forever.
They need to be dug in around the raspberry patch to a depth of 50-70 cm. This should be enough to prevent the roots from growing beyond the designated area.
There is an easier way, but it will have to be repeated year after year. Along the raspberry patch, you can plant plants that will prevent the bushes from growing.
For example, summer residents plant sorrel, beans, garlic. A narrow bed along the plants is enough so that the shoots do not go beyond the allocated area.
