Make good use of your gardening area! I know your think how, so am I. Here is a great way to do it.
Plant kohlrabi in the bed first. Then after it is harvest, plant green beans. After you harvest that plant your winter cold crop lettuce or kohlrabi again.
By doing that you have used your 1 spot and grow 3 different things.
I have not done it yet, I'm going to give it a try this year though!
Do you plant more then one thing in you boxes a year? If not what do you grow?
