Troubleshooting
Garland Chrysanthemum 'Shungiku' problems — and how to fix them
Garland Chrysanthemum 'Shungiku' (Glebionis coronaria 'Shungiku') 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.
Fast bolting
Warm weather and long days quickly push it to flower, intensifying flavour and ending leaf production. Sow in cool windows and harvest tips often.
Overly bitter leaves
Mature and drought-stressed foliage becomes harshly bitter. Cut only young shoots and keep watering consistent for the mildest taste.
Aphids on shoot tips
Soft new growth attracts aphid colonies. Check tips regularly and remove with water or a soft soap spray rather than chemicals on edible leaves.
Slugs and damping-off
Slugs devour seedlings and damp, crowded sowings damp-off. Sow thinly with good airflow and protect young plants from slugs.
