Hi, I have got 10 Geranium seedlings in a propagator in the back bedroom, they were sown 7 days ago and are now all up and at the two leaf stage.

I need the space in the propagator and want to put the geraniums into an unheated G/house.  Can this be done early in their growth? How hardy are they to cold but no frost?

Thanks FB

Are they pelargoniums or hardy geraniums?  Pelargoniums are not hardy and I wouldn't risk them in an unheated greenhouse as frosts are still likely for a couple of months.  I'm not sure about hardy geranium seedling hardiness.

Either way, as a general principle, don't take them straight from a heated propagator to an unheated greenhouse.  They need hardening off first or the shock will certainly do them no good.

Hi Yorkie,
Thanks for the reply.
I have checked the seed packet and they are 'Geranium Vista, Pelargonium  Half hardy perennial.'

[Yorkie]

Then I think it's a risk putting them out, even after being acclimatised.  What does the seed packet say about sowing / planting out dates and ongoing cultivation before planting out?

I composed a reply, which I've lost as I stopped went to check what you'd posted in the interim.

Essence - I don't think they will like an unheated greenhouse in February. I've just moved mine from the house to the heated one, but wound the temp up from "frost free".

Okay, I will keep them in the house for a while longer.

Thanks for the replies and advice they have been useful

Get some foil behing them, though!
