  • Some varieties are ‘runners’ which spread via underground rhizomes. Some varieties are ‘clumpers’ which also spread that way but much much slower. I would be wary of even planting a clumping type, because if you ever change your mind and want to remove it, it can still be challenging.

    People have great luck growing some smaller clumping varieties in containers which is probably the safest method. I’m actually trying to do that too just to jazz up an ugly concrete spot



  • This is my understanding too. After the plant dies it can release that nitrogen. While the legume grows, the benefit of nitrogen is negligible and negated by the fact that the legume is competing in the ground for water and other nutrients. The Three Sisters is a nice idea but there is a reason it’s not common practice. See also ‘companion planting’, the astrology of gardening. What plants want most is room to grow roots.

    The best thing to do with legumes is till them under before they go to seed, or add them to compost.
