If the newly planted Thuja hedge suddenly develops brown tips, this is not always a cause for concern. Where does the discoloration come from and what can you do to prevent brown tips?
Why does my thuja have brown tips and how can I prevent them?
Brown tips on a Thuja hedge can be caused by stress-related discoloration, pest infestation, sunburn or lack of care. To solve the problem, make sure you have enough water, protection from the sun and road s alt, and be careful when cutting.
Causes of brown tips of thuja
- Thuja hedge freshly planted
- Sunburn (cutting, location)
- watered too little
- Sprinkling s alt
- Pest Infestation
The brown tips often appear when you have just planted the hedge. The reason for the discoloration is that the tree initially puts all its energy into root formation and neglects to supply the shoot tips.
Give some organic plant help (€11.00 on Amazon), which you can get from gardening stores. It strengthens the tree of life so that it has more strength to form new shoots.
Be sure to avoid over-fertilization, as this is very harmful to the tree of life.
Brown tips due to pest infestation
Occasionally the leaf miner appears, causing brown tips on the thuja hedge. An infestation can be recognized by feeding passages in the shoots and fecal deposits on the leaves.
Treatment is only necessary if the infestation is very severe.
Remove brown tips
You can simply cut off the brown tips. Be careful not to cut too much, especially not into old wood.
Do not prune when the sun is shining strongly or the tree of life is very wet.
How to prevent brown tips on the tree of life
Make sure you have a good water supply. The soil must always be slightly moist, but waterlogging must be avoided at all costs.
Sprinkling s alt doesn't benefit the tree of life. Therefore, do not plant the hedge or tree too close to paths and roads that are sprinkled with road s alt in winter.
Very young thujas in particular suffer from strong sunlight. It can be helpful to give them some shade in the midday sun. This is especially true during winter.
Brown buds on the thuja
Brown buds are not a real problem. These are dried seed heads. You can simply break or cut these off.
Tip
If the thuja hedge turns brown on the inside, it is almost always a completely natural process. You usually don't have to do anything. Treatment is only necessary if care errors, diseases or pests are responsible.
