Swiss Chard 'Yellow Ribbon' problems — and how to fix them
Swiss Chard 'Yellow Ribbon' (Beta vulgaris subsp. cicla 'Yellow Ribbon') 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 in heat
Sustained heat or a cold spell pushes plants to seed; sow in succession and provide light afternoon shade through midsummer.
Beet leaf miner
Larvae tunnel pale blisters inside the leaves; remove affected leaves and exclude the flies with fine insect mesh.
Downy mildew and leaf spot
Cool, damp, crowded conditions cause yellowing or spotting; space for airflow, avoid overhead watering and clear plant debris.
Slugs and snails
Young leaves are grazed heavily at night; use barriers, traps or evening hand-picking, particularly on seedlings.
