The previous gardening thread got me thinking. One thing I've been mulling over is building a polytunnel in my yard to plant some veg and herbs. I have a black thumb and have had (no lie) zero success growing veg and herbs from either seeds or small plants. I think the two major problems have been cold springs and an overly shaded yard. Anyone have a polytunnel? Had a polytunnel? I must admit I am a huge River Cottage fan and got the idea from H F-W. Haha.
