Swiss Chard 'Peppermint' problems — and how to fix them
Swiss Chard 'Peppermint' (Beta vulgaris subsp. cicla 'Peppermint') 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.
Bolting
Heat or an early cold check pushes plants to flower; sow in succession, water steadily and give light afternoon shade in hot spells.
Beet leaf miner
Larvae mine pale blisters within the leaves; pick off affected leaves promptly and cover plants with fine insect mesh.
Faded stem colour
Insufficient light or over-mature leaves dull the pink striping; grow in full sun and harvest young for the brightest stems.
Slugs and snails
Seedlings and young leaves are heavily grazed overnight; protect with barriers, traps or evening hand-picking.
