Okay, so I live in South Western Ontario, and it's not really the may long weekend yet and I decided to grow a bunch of plants in these seed starter kits with the plastic cover to give a "greenhouse" effect for the growing environment. Out of all my seeds, the green string beans grew the fastest! They are about 6" tall now and they aren't standing up tall! They're just bending to the side now :( I don't know what to do? I can't put them outside because they will die from the frost! What can I do? I feel like they need support though, but I don't know if they are climbing types? I just don't want to have to put them outside and let them die :( Please help!
