Pests
Aphids on Lavender
Commonly affects: Lavandula angustifolia / L. x intermedia (Lavender)
Small soft-bodied insects cluster on new growth and flower spikes, sometimes causing distorted growth and sticky honeydew residue.
Potential Causes
- 1Aphids attracted to the soft, tender tissue of new growth and developing flower spikes
- 2Introduction from a nearby infested plant
- 3Ants farming aphid colonies for honeydew
Solution Steps
- 1Rinse affected growth gently with water to dislodge light infestations
- 2Apply insecticidal soap for more established infestations
- 3Control ant activity nearby, since ants protect and spread aphid colonies
- 4Encourage natural predators like ladybirds, which are effective against aphids in outdoor plantings
Prevention Tip
Lavender is generally quite pest-resistant thanks to its aromatic oils, but new tender growth can still attract aphids â check flower spikes as they develop.
