If the tips of the thuja turn yellow, you should definitely look into the causes. Yellow tips are almost always an indication that the thuja hedge is lacking something. What do you have to pay attention to when the tree of life turns yellow?
Why does thuja turn yellow and what can you do about it?
If the thuja turns yellow, there may be causes such as a location that is too moist or dry, a lack of nutrients, overfertilization, pest infestation or fungal diseases. This can be helped by watering more often, improving soil drainage or fertilizing with Epsom s alt if there is a magnesium deficiency.
Why does thuja turn yellow?
There are a number of causes that cause the tree of life to turn yellow or have yellow tips.
- Location too wet / too dry
- Nutrient Deficiency
- Overfertilization
- Pest Infestation
- Fungal diseases
The tree of life is very robust, so diseases and pests occur less frequently. Care errors or location errors are usually responsible for the yellow discoloration of the needles.
Incorrect care of thuja
Thuja likes soil that is always slightly moist and not waterlogged. If the soil dries out, the tips first turn yellow and then brown. More frequent watering helps here. If there is waterlogging, you must ensure that the soil is better drained.
The gardener often means too much when it comes to fertilizing. This is a real problem, especially with mineral fertilizers. Over-fertilization is just as harmful to the Thuja hedge as too few nutrients.
It is better to rely on organic fertilizers such as compost, horn shavings and manure. Mulches made from bark mulch are also good for providing nutrients.
Yellow tips due to magnesium deficiency
The tree of life is not very demanding. However, if there is a lack of magnesium, it causes the tree to turn yellow. Fertilizing with Epsom s alt can help. However, you should first take a soil sample and have it examined in the laboratory.
If there is a magnesium deficiency, fertilize the hedge with Epsom s alt. You must follow the dosage instructions exactly. Over-fertilization with Epsom s alt leads to acidification of the soil, which further weakens the thuja.
Epsom s alt can either be sprayed in liquid form or sprinkled on the ground in solid form. The tops and bottoms of the leaves are sprayed. Do not spray directly on the trunk. You must also not fertilize on a very sunny day.
Tip
You can easily chop up Thuja cuttings and add them to the compost. There is no risk of poisoning. However, the cuttings should be free of diseases and pests.
