when can I start hardening off my geraniums/pelargoniums, which I have grown from seed?

[parakeet]

The subject heading just about sums it up really. The seedlings are currently in my shed, which is my pseudo-greenhouse. Can I start hardening them off yet? (I live in the south east.)

I would, with caution.

Just keep an eye on the forecast.

Mmm - they were warning on GQT about this. I'm putting some tender things outside during the day on sunny days, but firmly putting them back in in the evening. GQT warned against fertilising plants and encouraging them to put on lots of soft growth.

Thanks!
