If a sage presents itself with yellow discoloration instead of silvery-green leaves, various causes can be responsible. In the first step, it should be made clear that it is not a yellow species, like golden sage. If this can be ruled out, the following triggers for the damage picture come into focus:

- The sage has been watered too often
- The fertilizer was overdosed
- There is drought stress
- Pests or diseases have attacked the plant
If the leaves turn yellow, there is usually a lack of care. Only water sage abundantly as a young plant. Older specimens are content with the natural rainfall. Fertilize with compost every 2 weeks from March to August. Health problems are also expressed in yellow leaves. A whole arsenal of environmentally friendly means is available for combating fungal diseases, cicadas and aphids.
