Troubleshooting
Tat Soi 'Yukina Savoy' problems — and how to fix them
Tat Soi 'Yukina Savoy' (Brassica rapa var. narinosa 'Yukina Savoy') 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 and long days push it to flower; the savoy type resists this better than flat tatsoi but still bolts in late-spring heat. Sow in cool windows and harvest young.
Flea beetles
Shotgun-hole pitting in leaves, worst on seedlings. Cover with fine insect mesh from sowing and keep plants growing quickly.
Cabbage caterpillars / aphids
Caterpillars chew foliage and aphids cluster in leaf crevices. Inspect undersides; use mesh, hand-pick, or a soft soap spray.
Downy / club root
Crowded, wet rosettes invite downy mildew; acidic or waterlogged ground risks clubroot. Space plants, water at the base, and rotate brassicas on a 3-4 year cycle.
