I recall writing in some detail about suitable times to grow various ‘green manure’ crops in the book ‘Trevor’s Kitchen Garden’ ( pp. 195 – 9). Now I realise, after working with organic guru, Jim Cronin in Co. Clare, that sowing these soil improving crops can be an almost weekly occurrence. This applies

Bowl of ‘green manure’ rye seeds ready for broadcast sowing by hand along vacant veg beds in polytunnel
especially when growing in polytunnels where soil temperatures are generally higher than outside.
Whenever Jim has cleared a patch of soil, a green manure is sown, even if the patch will be required to plant vegetable seedlings in a fortnight’s time. If one sees bare soil – scatter a few seeds of rye or phacelia or red clover. This is a good rule of thumb which lies at the heart of maintaining good microbial life in well managed soil.
