Forage Rye Green Manure (also known as Hungarian Grazing Rye) can be used anywhere in crop rotation plans and is one of the best for over wintering.

It’s an excellent nitrogen lifter and it can lift and release up to 90% of nitrate to the next crop. Rye has deep penetrative roots that help to break up heavy soils and so improve soil structure. It is brilliant at suppressing weeds as it grows quickly and continues to grow in cold conditions. It suits most soils and copes especially well with heavy clay ones. It does require the correct conditions to germinate in autumn (not too much rain) and watch out for slug/snails who like its tasty leaves and birds who like to nip off the tops!

It may be fairly hard to dig in after winter especially on heavy clay soils (good exercise though!) If it is difficult either loosen roots one day and then dig in a couple of days later, or cut down foliage and cover with a light excluding mulch such as black plastic for 3 weeks and it will then be easier to dig in. The foliage can also be added to your compost. Sow August to October and dig in during early spring.

Please note that forage rye releases a chemical that inhibits the growth of small seeds (particularly carrots, parsnips & spinach) so a month should be left after digging it in and before sowing the next crop. It does not pose a problem for transplants or young seedlings.
