Nutritious pasture plants such as alfalfa, clover and trefoil aren’t all that easy to grow. I know because I’ve been planting them for years. Normally you need to buy expensive seed, plant these seeds in good soil free of weeds, then hope for favourable growing conditions while the seedlings get started.

These plants are thriving in nothing more than a 4-foot depth of rock crushing waste with no tillage, tending or care. Click above to see what I mean.
