Pest identification
What's eating my purple sage?
Spittlebugs / froghoppers
Signs: White frothy masses on stems in spring; nymphs suck sap; some distortion but usually recovers well.
Control: Blast off firmly with a garden hose; no pesticide needed for healthy established plants.
Aphids
Signs: Soft colonies on shoot tips; leaves distort; sticky honeydew dulls the ornamental purple foliage.
Control: Water jet; insecticidal soap or neem oil; cut back and remove heavily infested stems.
Slugs & snails
Signs: Irregular holes in young leaves and shoots; worse in wet springs; slime trails on soil.
Control: Iron phosphate pellets; hand-pick at night; mulch away from stems.
Sage leafhopper (Eupteryx melissae)
Signs: Pale white stippling dots across leaves from sap feeding; adults jump quickly when disturbed.
Control: Insecticidal soap or pyrethrin spray; remove weeds nearby; reflective ground cover to disorient adults.

Purple Sage pests — FAQ
What is eating my purple sage?
Purple Sage faces the same pest pressures as culinary sage: spittlebugs are extremely common on the woody stems in spring, aphids attack soft new growth, and slugs target young shoots. Sage leafhoppers cause pale mottling on the purple leaves. The ornamental value means pest damage to foliage is especially visible and worth acting on promptly.
