I usually plant the big fava beans every year and they overwinter in my climate and produce flowers and fruit in the spring. If its a dry spring they suffer.
This year I'm going to try and create a grand mix of seeds.
I will add nasturtium, oats, calendula, peas,chick peas, poppies, clover and any other seeds I can get my hands on.
I am hoping that the variety of root depths will help keep them growing the spring is dry.
