After winter, thujas turn yellow, usually due to spring sunburn.
But there may be other reasons. We tell you why the thuja turns yellow after winter and what to do about it.
How to save a yellowed thuja
As mentioned above, the most common cause is spring sunburn.
To avoid it, you need to cover the trees. But not with film or spunbond: the material should be light, allowing air and light to pass through well.
Yellowing can also be caused by: failure to comply with planting deadlines, transplantation to a new location, chemical burn of roots due to melt water with technical salt and other reagents, diseases, etc.
If the plant's root system has not died, it can be saved.
First, you need to cut off the dried branches and cover the cuts with garden pitch.
If the yellowing is caused by spring sunburn, heavy watering will help.
If the problem is due to disease or pests, appropriate treatments are carried out on the crown of the plant.
All affected branches should be removed and burned. To disinfect the cuts, use a 5% solution of copper sulfate.
It is also necessary to disinfect all nearby growing bushes.
