As an evergreen plant, the Australian chestnut should never be left without leaves. It is not related to the native chestnut, which becomes bare in autumn. Therefore, leaf loss and regrowth are roughly balanced.
Why is my Australian chestnut losing leaves?
If an Australian chestnut tree loses leaves, this can be caused by too little or too much water, a lack of potassium, too little light or a location that is too cold. To prevent this, the plant should be watered regularly, fertilized and placed in a bright, warm location.
However, if your Australian chestnut develops brown tips or excessive leaves fall off, then the plant is not doing well and you should investigate the cause. Although the Australian chestnut is considered to be quite robust, it still has some needs. Therefore, errors in care could be the reason for the plant's illness.
Causes of brown leaves and leaf loss:
- watering too sparingly
- too moist or wet soil
- Potassium deficiency
- too little light
- too cold location
How can I help my Australian chestnut?
If your Australian chestnut tree is clearly not doing well, check the plant's substrate. If it is noticeably dry, then watering is probably necessary. If your Australian chestnut recovers afterwards, make sure to water it regularly in the future. However, if there is a potassium deficiency, the substrate is inconspicuous, as is the case if the plant is in an unsuitable location.
Rather moist substrate could indicate root rot. Expose the root ball of your Australian chestnut. He althy roots are firm and white. Soft and/or brownish roots, on the other hand, are not he althy. In this case, you should completely replace the old soil. Also cut off any diseased parts of the root ball. Then water the Australian chestnut sparingly for the next few weeks.
How can I prevent leaf loss in the future?
The best way to keep your Australian chestnut he althy is to take good care of it. It needs a relatively large amount of water, at least in the growth phase. Fertilizer is needed approximately every two to three weeks. If it contains little potassium, a deficiency can occur. Then switch to a different fertilizer. The location of the Australian chestnut should be warm and bright, but not in direct sunlight. You should accustom the plant to direct sunlight relatively slowly.
Tip
Appropriate care and location will keep your Australian chestnut he althy. This way there should be no loss of leaves.
