is it too late to sew tomato seeds in the green house ?

i dont think it is too late as mine are just coming through , good luck

I'm no expert, but surely it's not too late. Give it a go!

At the worst, they wont have time to ripen properly so you can learn how to make green chutney! lol. Give it a go.

the dropped fruits from last year are germinating in the soil as we speak. they should be fine.

And if all else fails......go out and buy some tomato plants ;-)
