sowed seeds out side in to the grand about 2 weeks now but still no show how can i till wot going on

[Yorkie]

Mine have taken about 12-14 days indoors so I wouldn't be at all surprised if yours take up to 3 weeks outside given the low temperatures overnight.

You could try starting some more off now, perhaps in pots, but I'd be a bit more patient with those you're waiting for too.

The other option is that they did germinate, but got eaten by slugs / snails as soon as they got above the ground

You could try using a finger to gently move aside some of the soil covering them and with any luck you'll find a curved, pale shoot about to reach the surface, in which case all is well.

If not you could delve down a bit further and try to find a few of the seeds; they could have started to rot in which case I would also suggest sowing some more indoors (always more reliable than outside where, as Yorkie says, they are vulnerable to slugs amongst other things.)
