There are several reasons for moss growing on the trunk:
- Environment: Dense planting of fruit trees, heavy shading of branches and leaves, prolonged high humidity in the orchard, poor ventilation, and insufficient light transmission in the orchard; excessive soil moisture.
- Excessive use of foliar fertilizers, especially those with heavy acidity, can cause moss to grow on tree branches and spread to leaves and fruits.
- Tree vigor: Weak tree vigor and old age can cause the plant’s root system to age and reduce its resistance.
To alleviate this:
- Prune smaller, severely affected branches, leaving most of the thicker branches intact.
- Purchase an iron brush from a gardening or hardware store. Use it to scrub the moss off the thicker branches.
- Apply Mr Ganick Bamboosa Extract or Mr Ganick Cuka Kayu Concentrate (for smaller gardens), diluted with 50ml + 1L of water, sprayed on the moss-covered tree stems. **Note: Only spray on the stems, do not spray on leaves or young branches.
- Apply once a week, repeating this treatment at least 3 times. If it rains within 3 hours after spraying, repeat the treatment. Apply during the daytime.
- Improvement should be observed after about 3 treatments. The moss will gradually fade and lighten during these 3 treatments.
