What a cute and clever idea! Clear around the planting area, for productive growth of the beans. Greate hideaway for kids in the yard, leave the grass in the center.c- I might do this even if i hate beans!
Making a cutting of a Split Leaf Philodendron (Monstera deliciosa). Clip so you get a little air-root. Put your cutting directly into the ground or in water, either works well. Cut away the little bit that remained on the mother plant.
