What's eating my broad-leaved thyme?

Spittlebugs (Froghoppers)

Signs: White frothy blobs around stems in May to June; enclosed nymphs suck sap and distort soft shoot tips

Control: Remove by hand or blast off with water; plants recover readily; no chemical treatment is normally required

Aphids

Signs: Colonies of small green or greyish insects on young shoot tips; honeydew deposits and occasional leaf curl

Control: Use insecticidal soap spray; attract hoverflies and parasitic wasps with companion planting of umbellifers nearby

Slugs and Snails

Signs: Irregular holes and ragged margins on leaves, particularly on young plants in cool damp weather

Control: Scatter iron phosphate pellets or use copper tape around container plants; improve drainage to make soil less hospitable

What is eating my broad-leaved thyme?

Broad-leaved thyme (Thymus pulegioides) is a low-maintenance herb whose pungent oils deter most pests. Spittlebugs are the most likely visitor in early summer, and aphids occasionally colonise tender new growth. In damp gardens, slugs may nibble young shoots.
