Great seeds so far

I was using cowpeas for a summer cover crop, and they didn't germinate consistently, so I replaced them with this sunn hemp. In about a week, all my beds are popping up in new crotolaria, so I'm very happy so far.

good product

lots of seeds in order, germinated well. Good for goat forage. My goats have cleaned my pasture of all the nasty things they like to eat and are not happy eating grass and clover. This will help repopulate my pasture with forage. I am growing a patch that they cannot get to for seed and seeding the rest as I rotate pasture.
