Garlic Chives problems — and how to fix them
Garlic Chives (Allium tuberosum) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Aggressive self-seeding
Left to flower, garlic chives drop abundant seed and can spread into a weed. Deadhead spent flower heads before seed sets to keep clumps contained.
Allium rust
Bright orange pustules on the leaves in damp seasons. Improve spacing and airflow, remove affected leaves, and avoid overhead watering to slow spread.
Crowded, congested clumps
Old clumps become dense and less productive over a few years. Lift and divide every 2-3 years in spring to rejuvenate vigor and leaf quality.
Onion thrips
Silvery streaking and distorted leaves signal thrips, worse in hot, dry spells. Hose off, encourage predatory insects, and keep plants well watered.
