Indian Mustard 'Tendergreen' problems — and how to fix them
Indian Mustard 'Tendergreen' (Brassica juncea 'Tendergreen') 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.
Flea beetles
Pinhole damage on leaves is common in warm, dry spring weather. Cover seedlings with insect mesh and keep them growing fast with steady water.
Bolting in long heat
More bolt-resistant than typical mustards, but prolonged heat and long days still trigger flowering. Sow in spring and autumn and harvest young.
Downy mildew
Pale upper-leaf patches with grey furry undersides in cool, damp conditions. Improve airflow, avoid overhead watering, and remove affected leaves.
Slug damage on seedlings
Tender young leaves attract slugs and snails. Protect early growth and clear damp hiding places near the bed.
