I've noticed it says some plants need hardening off after potting (I think) and before planting out in the garden. Sorry if I sound thick, but what exactly does it mean? What do I do when I get to this bit?
Thinking of growing tomato plants and stuff and want to get to grips with terminology.
Hardening off is when you take young plants from a warm glasshouse and transfer to a covered cold frame,aired during the day & covered at night,with fleece if frosty,this prepares the plant so isn't in shock when eventually placed outside,it's mainly done with bedding plants.
TBH most peeps do without them,I'm taking it you've got a glass house ?,has it got heat ? You can use it to do much the same job by venting. & heating off,fleece off etc.But if your really serious then go for one,although I would rather a poly tunnel any day. My local DIY store used to sell aluminum frames,quite small,so they are about.
This sort of thing might suit you,but if your handy with a hammer & saw,I bet you could knock one out in an afternoon. http://www.all4gardening.co.uk/ScProductDetail/_Cold-Frames/Complete-Triple-Wooden-Cold-Frame-Planter_1820.aspx
