A friend filled me in on Earth Buckets last weekend at our “South Bay” cocktail party. Essentially two nested plastic containers, garden-sized. The top container is filled with a potting mix and fertilizer, the bottom-nested container will hold water that enters via a pipe. The water wicks up as needed into the upper soil chamber, where any type of small plant you wish to try can grow.
I see they have them at our nursery in the ‘Stro – Hortica, pre-made. I’ll have to give one a try – since its time to play “kill the tomatoes” again.
