Wall garden with jars
By You do not need anything more than a piece of flat wood, metal clamps and jars. Tighten the clamps on the wood and put them in jars and tighten not fall. Put in the soil and plant flowers, ornamental plants, or the kitchen, plants needed for cooking.
How well do the plants grow without drainage? Did you notice any mold growth in the soil? That always seems to be my downfall in planters without drainage.
