I have decided to use my ten foot square dog pen around my compost pile. That will mean a LOT of nutrients around the perimeter going into the ground and a desire to cover the pen while hiding the compost pile. In the past I have tried half runners, but somehow they changed half way throught the season and were stringy. Could you experts in vertical gardening give me some ideas of what vegetables and sweetest/most productive verieties I should consider. No need for dried beans as the arthritis just wouldn't allow such lengthy shelling...and I can buy them so cheaply. THANK YOU!
