Topic: Mildew On Top Of The Soil ?

[George]

Hello All
One or two of my pots in the greenhouse have a patch of a powdery substance on the soil, when I water it puffs up like a whiff of smoke.
the plants in the greenhouse seem not to be affected by anything.
Do I need to sort it
regards George

Yes. Empty the greenhouse, burn every plant, sterilise the g/house with pure bleach. Grow nothing in it for 5 years.!

Hmmm, on the other hand it could be just a collection of salts from where you have been watering with tap water and nothing to worry about............

Blimey Palustris , that sounds a bit excessive, are you winding me up?

I think you may find that its the salts and minerals coming to the surface of your compost. its more common in cheap compost but nothing to worry about

Now would I do that?

It's just a fungi ;D No harm to anything, probably.

Sounds like a fungus but I`ve no idea which. It wouldn`t do any harm to water all the affected pots with Cheshunt Compound, just in case.
