Right Care for thuja hedges

  • up to three cuts per year
  • possible from spring to late summer

Frequently asked questions


Why is work clothing important when trimming the hedge?


The entire tree of life is poisonous. This can cause health problems not only when eating the green leaves. The sap that comes out can cause dermatological irritation. Consequently, work clothes are the way to go.

How to winter the hedge?


The evergreen foliage makes thuja hedges a popular planting in the home garden. Some varieties are hardy down to -30 degrees. It is important that the plants have enough liquid in the winter. Then wintering will not be a problem.

Why is wet weather bad for pruning?


You should not prune thuja on wet autumn days. Intersections are ideal for pathogens. In bad weather, the trees of life can not quickly close the injuries. In addition, the plant sap leaks out. However, this is vital for the thuja hedge.

What do I do in case of bare spots?


When pruning goes wrong, bare spots are commonplace. Often young shoots forgive the human error. In addition, it is possible to pull neighboring branches into the hole and fix them there. After a short time the hedge closes again.
