Spring
As early as you can planet – mustard or other Asian Green of your choice in the center. Bush snap peas inset a little from the rim of the pot. Plant pansies in between.
Summer
Cut off peas at ground level. Remove remnants. In late May, transplant a tomato plant into the center and stake it. Around August, direct sow kale under the tomato, removing lower leaves as needed. Thin to six inches apart.
Fall
Cut tomato off at ground level when it fades, so as not to dislodge the kale. Clean up as needed, and plant (yellow) tulips where there is available space.
