Hey Peter,This is Debbie from mercy Cares For Kids (you were out here several years ago to teach the children about composting. This year we are looking for a vine that will grow and spread fast to cover an old swing set frame to make a shady play area for the children. We saw the large bottle gourds and thought that would be a great learning project as well as providing shade. The children would be able to watch it go from vine to producing flowers and then the gourds. Once they could be harvested , the children could make bird houses or use them for decorations at their family harvest luncheon in November. Do you think the vines would grow fast enough to provide shade? (We were thinking of using either string, wire or netting for it to climb on. Any helpful suggestions?
