I think germination times have gone out of the window this year...
I sowed three packets of 'Shirley' toms, and they've taken a month to germinate, which is unheard of these days, so I guess you might want to wait a while longer!
Some cheapo freebie 'Roma' from last year just romped away though!
Keep this thread going though, as the 'Shirley' were in pretty old compost which actually ponged a bit, and I got a refund , (or three new packets from our fave GC, who got the Unwins rep to refund them, so all was not lost), and to compensate, I bought a brand-new bag of peat-free compost with John Innes, with which another customer had claimed 100% germination, so we'll see what happens!
Phew...
