Broad bean ignoramus

[Two_Sheds]

a human fed on organic food who [does] not ... carry parasites can actually improve the soil and ecosystem

... as in the Hunza people, who apparently have very little disease and use their own manure to grow their food

The book explains how intestinal worms & other bugs are killed in a properly constructed compost heap: it's a combination of heat & time (high heat or long time).

I keep banging on about this book, but it is awesome

Back to your question, Kathyd, they do not need to be in the gh/polytunnel. Try re-sowing in Feb-March, outdoors.
