Yellowing Leaves on Rosemary
Commonly affects: Salvia rosmarinus (Rosemary)
Needle-like leaves turn pale yellow, sometimes starting with older, lower growth. The plant may also look generally less vigorous than expected.
Potential Causes
- 1Overwatering, the most common cause of yellowing in a plant adapted to dry conditions
- 2Poor drainage keeping roots too wet for extended periods
- 3Nutrient deficiency in old, depleted potting mix
- 4Insufficient light reducing overall plant vigour
Solution Steps
- 1Check soil moisture before assuming a feeding issue � rosemary yellowing is overwhelmingly linked to overwatering rather than lack of nutrients.
- 2Allow the soil to dry out significantly between waterings going forward.
- 3Ensure the pot has good drainage and isn't sitting in standing water.
- 4If watering practice is already correct, apply a light, balanced feed and move the plant to a brighter spot.
Prevention Tip
Resist the urge to water rosemary on a fixed schedule � let the soil dry out substantially between waterings, since overwatering is far more likely to cause yellowing than underwatering.
