Dwarf Frenchies!

[smallblueplanet]

French bush beans, what sort of temperature range do they prefer?

I've sowed some seeds in rootrainers and they've come thru, I was thinking they'd be okay in the unheated greenhouse until the get planted up into containers and put outside. But its been somewhat colder at night than I'd thought it would be

What sort of minimum temps will they be happy with?

[Flummery]

I always thought they were like climbing frenchies and runners in that they were allergic to frost (aren't we all?). I sowed my first lot yesterday and they're in an unheated but double glazed and well insulated garden room. Don't expect to see them for another week or so. I think frost would get them, but having said that, I sowed some achocha - vine swap - which are tender and I left one in the cold greenhouse as an experiment (too many germinated - like ALL of them!). It's still going strong.

So, not a useful answer!

Similar to tomatoes - they are quite tender and like the warmth.

Normally you wouldn't risk less than about 10 degrees at the start.

Once they get older and tougher they can take a bit more cold, but they are really warm lovers.

They like to get into a warm bed. If sowing in pots, I only water them in when sowing and never again till they are up.

They certainly dislike frost but I find a cold wind is the thing that really yellows them. Cloches or a wind break really helpful.

These days I grow them in an unheated house and find that is great in spring. either 3 to a two litre pot or in the boarder. I don't really bother moving the operation outside till June.

I usually stake them(put a cork on top so you don't poke your eye out) in groups of three per stake. or stretch a wire up the row. Further i use some small scissors to snip them off as I find they are quite easy plants to tear when harvesting
