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 primarily planted as a hedge. How to recognize a fungal infestation on Thuja Smaragd and how to combat it.
How do you recognize and combat fungal infestation on emerald thuja?
A fungal attack on Smaragd Thuja is shown by brown, dried shoots. To combat it, affected shoots should be generously removed, the tree thinned out and treated with fungicide. Prevention is achieved through sufficient planting distance and strengthening agents.
Identifying fungal infestation of the emerald thuja
If the shoots of the emerald thuja turn brown, dry out or even fall off, you should examine the tree of life for fungal infestation. To be sure, ask a professional for advice.
Fungal infestation is usually caused by too much moisture in the soil or on the shoots themselves. In the case of the Smaragd Thuja, the cause may be that the tree was planted too close together.
Root rot is also caused by fungi. It is caused by waterlogging and occurs on soils that are not permeable to water. Due to the standing water, the roots cannot absorb nutrients or moisture and the tree of life dies.
How to combat fungal infestation on the emerald thuja
- Cut off affected shoots generously
- dispose of in household waste or burn
- Thinning out the tree of life
- Treat emerald thuja with fungicide
Do not throw the cuttings into the compost heap, as the fungal spores will then continue to multiply.
Clean the cutting tools thoroughly after use to avoid spreading the spores to other plants.
Fungicides for fungal infestation on Smaragd Thuja are available from specialist retailers. When using it, follow the instructions on the packaging carefully to avoid putting too much strain on the environment.
Prevention of fungal infestation
Make sure the soil is permeable to water. Light 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 population of thuja is threatened. If in doubt, you should completely remove heavily infested trees and thus increase the planting distance.
Use tonics that are offered specifically for the Tree of Life. This makes the Smaragd Thuja more resistant to fungal attack.
Tip
Thuja Smaragd is particularly susceptible to fungal attack when planted as a hedge. The planting distance here is simply too small. You should rather maintain emerald thuja as a solitary plant in the garden.
