greenhouse lettuce problems
« on: November 06, 2008, 20:43 »
HELP PLEASE

When i opened the g/house doors this morning i noticed patches on the lettuce. On the undersides of the leaves were patches of little white 'grains' :shock: Is this mildew or something because of damp?

I've been opening the doors everyday but this hasn't always dried off the condensation formed overnight because we've been having such damp, still weather.I've stripped off all the effected leaves is there anything else i should be doing?

The border is full of winter salad and i wouldn't want to loose the lot :cry:

It'll be some kind of mould or other.

All I'd do is to keep your doors open 24hrs a day unless there's a frost forecast to try to dry it out a bit. :?

Wouldn't that just be whitefly, casings or eggs.
