The enjoyment of the thuja in the pot often only lasts for a short time when the needles turn brown and the tree of life is obviously ailing. Incorrect care is usually responsible for the thuja turning brown. Why is it when thuja turns brown in the pot?
If the thuja turns brown in the pot, there may be a lack or excess of water
Why does the thuja turn brown in the pot?
The following causes can be responsible for the tree of life turning brown:
- Tree of life dried up
- Waterlogging in the bottom of the pot
- sunburn
- frost damage
- pest infestation
- fungus
The most common cause of discoloration is improper water supply. The substrate was not watered often enough, so the tree of life slowly dried up. This can also happen if the pot is too small.
If the thuja has brown tips, you should examine the tree of life for the dreaded dieback.
Water the tree of life correctly in the pot
- Never let the substrate dry out completely
- Avoid waterlogging
- Do not place tubs on saucers outside
- Do not expose the pot directly to the midday sun
- Do not wet the thuja leaves
- water in the morning
Even before planting, make sure you have a good water supply. Place the tree of life in a bucket of water for about 24 hours beforehand.
Watering is also necessary in winter when it has been very dry for a long time. Watering is done on frost-free days.
Check thuja for pest infestation
A common pest found on thuja is the leaf miner. It flies in the spring and lays its eggs on the leaves. The later larvae eat into the tunnels and first kill the thuja tops and later the whole tree.
In the hedge in the field, the tree of life usually copes well with an infestation on its own. If it is grown in a bucket, you should do something right away.
Cut off the affected tips of the thuja in the pot generously. In the case of a heavy infestation, use a commercially available spray, which you apply once before the pest takes flight and once afterwards.
tips
Thuja in the pot is even more susceptible to waterlogging and over-fertilization than Thuja in the hedge or as a single tree in the garden. Also, the tree of life in the tub is not so hardy and must be wintered frost-free or provided with winter protection.
