Chrysanthemum Greens problems — and how to fix them
Chrysanthemum Greens (Glebionis coronaria) 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.
Rapid bolting
Heat and long days send it quickly to flower, turning leaves strong and resinous. Sow in cool seasons and harvest tips continuously to delay flowering.
Bitter, tough leaves
Older foliage and water-stressed plants taste harshly bitter. Pick only young shoots and keep moisture steady for the mildest flavour.
Aphids
Cluster on tender new growth and flower buds. Inspect shoot tips and rinse off or use a soft soap spray; avoid pesticides on edible leaves.
Leaf miners / slugs
Leaf miners trail through foliage and slugs shred seedlings in damp weather. Remove mined leaves and protect young plants with barriers.
