Any recommended (organic?) mold killers for greehouse soil??

[nomis]

The tomatoes we started early in the house managed to get a bit of mold in their soil - from the condensation on the windows they were next to I assume.

Anyway, I stupidly managed to transfer this into their new composted ground in the big poly greenhouse. So now there is mold in there, on the soil near all 20 toms

Is there any way to kill the mold without damaging the plants?

Thanks

Sounds like everything is too wet?

[nomis]

Possibly

But the mold was definitely transferred from the house, its the same stuff I get on my windows some times.

Need to get rid of it...

What sort of mould? Have you got a photo?

Is the mould affecting the tomatoes? I have mould in the beds in my greenhouse and so far (touch wood) had no problems.
Try turning the soil over with a hand fork to get a bit of air into it and improve the drainage.

Open the door an let some air in there. You only really need to have the door shut at night now. Good ventilation is the best cure for mold.

The greenhouse has 6 (mosquito-netted) vents on the sides, I cant really go twice a day to open and close them. Maye I shall try leaving 2 of them open 24/7 though.

I can get a pic of the mold tomorrow. Its pure white.

Thanks!

Well, hate to admit it but I agree with Zazen....too wet.... with often an element of over feeding the soil.

Ventilation will make a difference with botrytis etc... but not algae growing on the soil surface.

Its not relly a big deal just scratch up soil surface regularly.

Try a little thin layer of sand on top. Better drainage: it dries out quicker.

But that's what you have to do with greenhouses? If it's warm you can leave them open, but leaving them shut all the time surely can't work very well?

Buy self opening vents:: make a tremendous difference.

I agree. Greenhouses don't look after themselves. If you let it get too hot, you run the risk of losing plants too. It's as bad as getting too cold.
