I am planning to build mini-green houses for my pumpkins this year. I plan to a 4'x4' square out of 1"x3" lumber and use fiberglass rods to flex a canope over my plants. I live on the Cumberland Plateau in East Tennessee and we have some possible late frosts in early May. Last year I lost a couple of plants because of this. I also want to use this method along with Sevin to prevent cucumber beetles. Do you think I'm wasting my time on these structures? Mark (mherndon@InfoAve.Net)
