Aphids on Rosemary New Growth
Commonly affects: Salvia rosmarinus (Rosemary)
Small clusters of soft-bodied insects gather on tender new shoot tips, sometimes leaving sticky honeydew residue behind. Affected new growth may look slightly distorted.
Potential Causes
- 1Warm weather and fresh, tender new growth attracting aphid colonisation
- 2Ants farming and protecting aphid colonies for honeydew
- 3Nearby infested plants seeding new colonies onto rosemary
Solution Steps
- 1Rinse affected shoot tips with a strong jet of water to dislodge colonies.
- 2Apply insecticidal soap to remaining aphids, focusing on new growth.
- 3Encourage ladybugs and other natural predators in outdoor plantings.
- 4Rinse harvested sprigs thoroughly before culinary use, regardless of treatment.
Prevention Tip
Check new growth tips periodically during warm weather, since aphids specifically target rosemary's soft, tender new shoots rather than the tougher established foliage.
