Forcing Rhubarb
Just a week ago I found a discarded black plastic dustbin in a skip. I had been looking for something to completely exclude all light from my rhubarb crowns.
This patch of 'Timperley Early' is nearly 4 years old, so the plant is strong enough to withstand forcing. Just by excluding all light during the first few months of growing produces much sweeter and more tender sticks of rhubarb at the beginning of the season. This does put somewhat of a strain on the plant, but this is a patch of rhubarb which I am going to move, dig up or give away next year.
Many more of my first set of early tomato seedlings have germinated in my heated propagator. Once again the variety I have named Great Wall of China is well ahead, all 7 of the seeds planted are up. 100% germination rate in 7 days!
