Mustard Greens in Barnhill

Sow small batches around 23rd March - 13th September, setting seed about 1 cm deep in prepared soil or compost. Sow a fresh batch every 21 days for a steady supply of young leaves rather than one glut.

When seedlings are large enough to handle from 28th June, thin them to their final spacing so they do not crowd each other. Keep the strongest plants and snip extras at soil level to avoid disturbing the roots.

From 25th June, check plants often and protect them from slugs and snails, which can strip young leaves overnight. Use pellets only if needed and follow the label, or add barriers and hand-pick after rain.

From 2nd July until 20th November, keep the soil evenly moist, especially in warm spells and under cover. Water at the base of the plants so growth stays steady and the leaves stay tender.

Start picking from 18th July once plants are well developed. Cut outer leaves little and often for a cut-and-come-again crop, or lift whole plants if you want them young and mild.
