Sow and Plant
In areas with cooler summers, mustard can be sown almost all year round, except for the coldest mid winter months. In areas with hot summers, avoid sowing in the hot mid summer months. Sow in late summer to use mustard as a short-term autumn green manure. Broadcast seed into cultivated soil so that the seeds are about 5 cm apart and 1 cm deep. Thin to 15 cm apart in all directions.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.
Use young leaves in salads and older ones for cooking. Mustard residue suppresses soil-borne nematodes, so it is an excellent green manure to grow before potatoes.
Chop down the green foliage with a hoe and turn it under before it starts to flower.
Irrigation is often needed to get a good stand if autumn is dry.
