Just to revive this thread. I looked to see if it was ok to feed raddishes and the leaves. I planted some raddish seeds (about 25) in a tray, put them outside and they have grown really well into thin raddishes with loads of leaves in the tray in about 4 weeks. If anyone wants to have a go they are so easy. This will not quite give my lot 2 each! so will be planting more later. There are loads of seeds in the packet, and very cheap to buy. x
