Thuja Smaragd is a somewhat sensitive variety of the tree of life. It suffers from fungal attack more quickly than, for example, Thuja Brabant, which is mainly planted as a hedge. How to recognize a fungal attack on Thuja Smaragd and how to fight it.

Recognize fungal infestation of the Smaragd Thuja

If the shoots of the emerald thuja turn brown, dry up or even fall off, you should check the tree of life for fungal infestation. To be absolutely sure, ask a professional for advice.

In most cases, fungal infestation is caused by too much moisture in the soil or on the shoots themselves. In the case of the Smaragd Thuja, the cause can be that the tree was planted too densely.

Root rot is also caused by fungi. It is triggered by waterlogging and occurs on soil that is not sufficiently permeable to water. Because of the standing water, the roots can absorb neither nutrients nor moisture and the tree of life dies.

How to fight a fungal attack on the emerald thuja

  • Cut off affected shoots generously
  • dispose of with household waste or incinerate
  • Thin out the tree of life
  • Treat emerald thuja with fungicide

Never throw the cuttings on the compost heap, as the fungal spores will then continue to multiply.

Thoroughly clean the cutting tools after use to avoid spreading the spores to other plants.

You can get fungicides for fungal attack on Smaragd Thuja in specialist shops. When using, follow the instructions on the packaging carefully so as not to pollute the environment too much.

Prevention of fungal attack

Make sure the floor is permeable to water. Thin out the tree of life more often so that the air can circulate better.

If the emerald thuja is too close to other plants, for example in the hedge, the entire thuja stock is threatened. If in doubt, you should completely remove heavily infested trees and thus increase the planting distance.

Use tonics sold specifically for the Tree of Life. This makes the Smaragd Thuja more resistant to fungal attack.

tips

Thuja Smaragd is particularly susceptible to fungal attack when planted as a hedge. The planting distance is simply too small here. Smaragd Thuja should rather be cared for as a solitaire in the garden.
