A vertical planter with a worm tower in the center. You add kitchen scraps into the center tower which creates a compost tea that drips out the bottom, then you add it back into the plants. Each hole can grow a different plant. 50 plants in 4 sq.
Reuse an old tree to make a log pathway in your garden. Good use of "yard" trees and other wood that can't be milled; works much better in climates without termites. Good drainage under the log rounds will make the path last longer.
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!
