Didn't they use to recommend dilute Jeyes Fluid? It always puzzled
me, as I couldn't see how it could avoid killing off the
beneficial
organisms along with the harmful ones.

That would apply to any form of sterilisation, wouldn't it?

I've always thought it must, yes; which is why I'd tend to say
replace the soil if possible. But I've never run a greenhouse, so I'm
being theoretical.
