I had a bad mildew problem in my greenhouse this year :-(


Empty the GH, scrub it out, leave the door and vents wide open to
let
frost in.


I have a number of things I overwinter in there, so I don't really want to
leave it standing open. Is there another way?

Frost 'isn't' necessary, IMO. a good clean out on a dry and preferably
windy day is and DO let things dry out afterwards..


If you leave it over night (and plants out) and it looks a bit chilly
then fleece is always an option against very light frosts. You don;t
give a locaion so its hard to say if this would work.

Citrox is also suitable for use on plants (not seedlings IIRC) so you
can have no worries about accidentally spilling it whereas Jeyes will
kill plants. (Not sure of dilution of Jeyes.. Long time since I used
any!-) Prolly about 5 - 10% or something. Certainly not more.

There's some evidence that Sodium bicarb inhibhits mildew groth on
plants so might be useful for cleaning as well.
