Other Names - Sinapis Alba…

White mustard prefers to grow in the cooler months and is promptly killed by frosts. This makes it an ideal green manure for people who prefer not to do too much digging as the dead autumn leaves can simply be left on the surface as a mulch and during the cold winter months the valuable organic matter will gradually be incorporated into the soil with the help of worms and other bugs.

  • Excellent for improving soil structure.
  • Fast growing.
  • Minimal digging required.

Suitable For - Green manure in vegetable and fruit gardens, groundcover, weed suppressant

Sowing Months - March - September

Sowing Guide

Scatter the seeds as evenly as possible on the surface of the prepared seed bed.
Lightly rake the surface to cover the seeds.
Water the newly sown seeds well.


Growing On

Water the young seedlings well until established.
Established plants need regular watering especially in dry periods.
The plants are frost tender and will be killed by the first autumn frosts.


Digging In

The plants can be cut down using a garden spade or shears, 7 - 8 weeks after sowing or just before flowering.
Leave to wilt on the surface of the soil for a few days before digging in.
Dig the plants into the soil at the depth of 20 - 25 cm with a sharp spade or rotovator.
If killed naturally by autumn frosts, dig in as normal or if preferred simply leave the organic matter on the surface to decay over the winter months. During this time the plant material will gradually be incorporated into the soil with the help of bugs and worms. In spring dig in any remaining organic matter.
Avoid growing any vegetables in the soil for at least 3 - 4 weeks after digging in so that the green manure has time to decompose.

TIP

White mustard belongs to the brassica family and therefore should not be followed by any brassica vegetables such as cabbage, sprouts, cauliflower, radish, broccoli etc. as this can lead to a build up of brassica pests and diseases.
