Winter Tares 'Vicia sativa', also known as 'Vetches' is a hardy annual that can be sown March-May or July-September for over-wintering. It is good at nitrogen fixing and for weed suppression on heavier soils but avoid acid or dry soils and dig in before flowering.
Winter Tares green manure is part of the legume family so grow on ground with/after legumes in a crop rotation plan. Any harmful pests & diseases will show up in the green manure rather than the more valuable veg. It helps to fix nitrogen and once dug in will fertilise the following nitrogen hungry crops like brassicas.
Protect from slugs/snails and birds especially pigeons who like to nip the tops off. Please note that Winter Tares releases a chemical that inhibits the growth of small seeds (particularly carrots, parsnips & spinach) so a month should be left after digging it in before sowing the next crop. It does not pose a problem for transplants or young seedlings.
Winter Tares (Vetches) Green Manure Seed Sowing Advice
|When to Sow:||March, April, May, July, August, September.|
|Growing period:||2-3 months.|
|Ideal Soil Type:||Heavier soils, avoid acid or dry soils.|
|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 and dig in to a depth of 2.5cm. Rake the soil and lightly firm down and water well. In dry periods you may need to water until the green manure is established. (Rows can be sown but are not as good for weed suppression).|
|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.|
