I don,t think you have much choice really, other than to ask your neighbour to keep an eye on them for you, explain that you don,t want to hold them responsible if they should die off, after all it,s only a matter of keeping them moist and warm, Derek.

I guess you might stand them on capillary matting - you could cut a strand of it off and trail it from a water container under the lid of the propagator and into contact with the matting there.

I don't like to put the extra responsibility of plants on my neighbour, the cats are enough (anyway, I wouldn't trust her with anything so important as plants!). Before we go away I give pot plants an overdose water and place them in the shade. Does the electric propagator need to be switched on for the ten days that you are away - it's not very long?

I agree with Bulba..I wouldn't leave your propagator switched on..and a good watering and shade is best..To be honest,I put mine in the bottom of the shower ,with the tray or propagator on an old towel...at least it's a warmer environment than outside..nights coming cooler now..

Thank you everyone. I'm probably nattering over nothing.
Bloomer/Bulba; I agree it would be a bit daft to leave its switch on.
Steragram; That sounds like a good idea.

Perhaps in the semi-shade with the capilliary watering should do the trick, fingers crossed.

Thanks!
