Digging in Green Manure ?

never used it  but ive seen plotholders an they dig it all in

I grow quite a bit of grazing rye every winter, sometimes mixed with winter tares / vetch. I have 25 poles altogether, so usually have about 10 poles of grazing rye. Because I have back and joint problems I can't do much digging, so tend to either strim the rye, or use a hover mower, around late February to early March. Then I rotovate it in. Sometimes it takes 2 rotovating sessions to get it all neatly covered, including the roots. Then you must leave it a few weeks before sowing small seeds, as the rye gives off a germination inhibiting chemical for a while  -  though you can plant sizable seedings, like pumpkins...
And I always leave an uncut fringe of rye around the edge of the plot. it will grow to about 6 feet tall, and provide some wind protection and privacy. It gives seed heads as long as your finger, which you can sow again in autumn....

Depends on the green manure.  Ideally dig it in, but mustard or phacelia is much easier to just pull up in handfuls and put in the compost bin. I have usually just emptied the bin of last year's rotted stuff, so I have space available.

I tried grazing rye once.  Never again.  It's too tough to dig in and too hard to pull up. I don't have a rotavator.....or even a great big tractor and plough.

Oh! Dont say that! I've grown rye this year as green manure. I have a rotavator, so was just going to go over it with that a few times.  Wasn't going to trim or anything as it is only around 15 cms at the minute.  I have quite soft sandy soil, so hoping it will just get churned up in the blades.

I like phacelia as a green manure - if you let it flower you get all sorts of lovely pollinators visit the plot. Red clover is good for that as well. But then I like a few flowers round the place - as there are hay fever sufferers in the family it's no use doing cut flowers. I do borage as well for the same reason (on compost heap, flowers are edible).

Fenugreek needs keeping an eye on as it can get away with itself if you don't get it dug in fast enough. But as you can plant that in August you can let it go and dig it in end of September or in October and it doesn't matter if there's quite a bit of it as it has winter to do its own thing in the ground.

The one that really needs to be cut back before flowering is buckwheat. That's a glorious self seeder - beats Icelandic poppies but quite some.
