How to prunePrune lightly: soft green shoot tips in spring and spent flowers soon after flowering, to keep thyme compact and bushy. Note: thyme often fails to reshoot from old woody stems, so replace old straggly plants with new ones from cuttings.

What you will see

Shiny purple-green beetles (¼–¼ in) and larvae eat leaves and flowers; leaves are reduced to short stumps.

The source says: the leaves can be damaged by rosemary beetles.

When to look

From late summer to spring

How to protect

  1. Prevention
    • Healthy plants usually tolerate it, so the beetle can be tolerated; encourage birds, frogs and ground beetles.
  2. By hand fall to springPick off beetles and larvae by hand or shake them onto newspaper.
