Spring Mix Green Manure Seeds
Green Manure Seeds from Sow Seeds Ltd
Our Spring mix includes Mustard, Tares and Italian Ryegrass which make an excellent combination to grow especially in early spring as they germinate at low temperatures.
Mustard is quick growing and can be sown from March - September for a period of 2-4 months. It suits most soils and produces lots of leafy growth - excellent for soils lacking organic matter. The bulky foliage helps to improve soil texture and moisture retention once incorporated. It is part of the brassica family.
Produces lots of bulky foliage that improves the soils fertility by adding organic matter when dug in; improves the texture of the soil and also suppresses weeds. Tares is also good at fixing nitrogen in the soil, which is good for the following crop as nitrogen helps to promote healthy leaf and stem growth. It is part of the legume family.
A good at suppressing weeds and fits anywhere into crop rotation plans. It is not as invasive as perennial ryegrass and has the ability to lift nitrogen from the soil and once dug in slowly release it to the following crop.

How to Sow: | Prepare the soil by roughly digging it over and removing any weeds. Lightly tread the soil, and then sow the seeds by broadcast sowing (i.e. scattering evenly) for good coverage. Rows can be sown but are not as good for weed suppression. Rake the soil and water well. In dry periods you may need to water until the green manure is established. | |||||||||||||||||
Care: | The green manure should be cut down before flowering when the stems are nice and soft as they decompose quicker, retain more beneficial nutrients and are easier to incorporate into the soil. They can be dug into the soil by turning over into the top 15cms or left on the top as a mulch, the worms will drag down the organic matter and help to aerate the soil. | |||||||||||||||||
