Now I've made the hot bed - a la Monty Donn- and am ready to plant sweet potatoes and Melons. the spuds down below and the melons up on a hill.
I have only used Hot Beds in winter and spring so I do not know a lot about summer use,but at this rate you will not be growing Sweet Potatoes you will Growing Baked Potatoes instead :shock:
that black teram will heat it up jim when the sun is on it,try folding the sides up a bit,i think you should be looking at around 30c,
What's teram? I was wondering if I could use my big rubble sack, full of fresh manure, as a hot bed next year. Is Monty Don's idea on a website somewhere?
