A friend of mine is using an old microwave to sterilise soil before
using for cuttings/seeds etc. in his greenhouse.


Is it worth doing?
Will it kill off "good things" as well as bad?



I used to work in a chrysanthemum nursery and the soil was steamed for some
considerable time before new plants were put in, didn't seem to kill
anything they needed. Microwave will heat the soil to the same sort of temp
as steam.
