Thuja Brabant is a particularly robust and disease-resistant variety of arborvitae that is preferably planted as a hedge. Diseases occur only rarely. Most of the time these are care errors. What diseases do you need to pay attention to?
What diseases can affect Thuja Brabant?
Thuja Brabant Diseases are rare because this arborvitae variety is very robust. Possible problems such as brown needles often arise from care errors such as root rot, too little light, over-fertilization or fungal infestation. Pests such as leaf miners can also occur.
Thuja Brabant is resistant to diseases
Thuja Brabant is a very robust tree of life. Diseases almost never occur. If the thuja suffers from needle discoloration, dead shoots or weak growth, care errors are usually responsible.
Thuja Brabant turns brown
If Thuja Brabant turns brown, there may be different reasons for this:
- Root rot
- too little light
- Burns from the sun
- Overfertilization
- Pest Infestation
- Fungal diseases
The most common cause of problems with the Thuja Brabant are errors in the care of the hedge. Root rot caused by waterlogging is particularly dangerous.
Brown needles can be caused by a location that is too shady, but also by burns in direct midday sun.
Overfertilization is also a problem that can lead to brown and dry needles. If the needles turn yellow, the soil should be checked for a magnesium deficiency.
Pests and fungal infestation
Apart from the leaf miner, there are no pests that cause diseases of Thuja Brabant. Fungal infestation occurs when the plants in the hedge are too dense and are not occasionally thinned out.
Avoid care mistakes for Thuja Brabant
- Watering in dry times
- Avoid waterlogging
- occasionally thin out
- never over-fertilize
Thuja Brabant likes a slightly moist location without waterlogging. Only plant the tree of life in a well-prepared place with permeable soil. In dry times, water regularly, even in winter.
Avoid wetting the leaves, especially in the evening. The moisture can then no longer evaporate and thus offers fungal spores a good opportunity to nest.
Many gardeners overdo it when fertilizing. Thuja Brabant must not be fertilized too heavily or too often, as this will burn the roots. You will then no longer be able to absorb nutrients and fluids.
Tip
Occasionally the leaf miner attacks Thuja Brabant. If the infestation is only mild, it's not that bad. Only a severe pest infestation can severely weaken the tree of life.
