Chewed or severed stems

Young stems are notched, scraped, hollowed, or cut near the soil line.

Close botanical observation of chewed or severed stems, presented as a visual symptom rather than a diagnosis.

Look before acting

A visual match narrows questions. It does not prove a diagnosis.

Compare the location, pattern, affected plant parts, recent weather, watering, and changes in care before choosing a response.

Possible causes

Keep the list open at first.

01Cutworms
02Rodents
03Slugs
04Stem borers
05Mechanical injury

Questions to answer

Look at the whole plant and root zone.

  1. Is damage at night or near soil level?
  2. Is the stem cut cleanly or hollowed?
  3. Are tracks, frass, or slime present?
  4. Are several plants affected in a row?

Low-risk actions

Change one thing at a time.

  1. Inspect after dark and around the stem base.
  2. Protect replacement seedlings with an appropriate collar where cutworms are confirmed.
  3. Remove nearby hiding debris selectively.
  4. Identify borers before cutting into a living stem.
