Hi All

My brassica seedlings are all dying, and I'm not sure what I've done
wrong. If anyone has any suggestions, they'd be gratefully received.

Here are the details: I sowed some seeds of cabbages, broccoli, and
cauliflower in seed trays in my greenhouse about a month ago. They all
germinated nicely and looked very healthy at first, but most of them
have since died. They are in 40-compartment module trays, 1 or 2 seeds
per compartment, so I don't think they can be too crowded. I've watered
them once or twice a week, when they have started to look dry. The
greenhouse isn't heated.

Any ideas? Too cold? Too hot? Too much water? Not enough water? Anything
else I might have done wrong?

Many thanks
Adam

Provided it's not an especially cold part of the UK I would always grow on,
even germinate, seedlings of Brassicas outside, but watch the pigeons.
Probably too extreme temperatures in the greenhouse recently with the spring
sun and cold nights.

Compost contains herbicide?

The compost is straight out of a bag of general purpose potting compost
from a garden centre. Surely they wouldn't put herbicides in, would they?

Thanks. That makes sense. It probably has been getting quite warm during
the day lately. I'll take the surviving ones outside and hope they
cheer up a bit.

No need to watch the pigeons: the cats do an excellent job of that all
by themselves!

If it's the GCs own brand it could well be the problem. Worth paying for a
quality product like Levingtons IMO.
