Emergency beans

I seem to be having my usual bean disaster: my sown in situ ones haven't appeared again (this happened last year too) . There are signs of stems so I think they've fattened up the local snails. Good job I sowed emergency ones in pots about two weeks ago. Just hardening them off ready for planting this weekend. Snail patrol will have to be daily once they're in. Got to guard my precious ones. These are climbing French beans, by the way.
