Unheated greenhouse

**Containergardener** · 15-04-2016, 11:28 AM

Ive only salads in mine , I've sown leeks, onions but I'm not sure if it is too cold for them. I have to keep everything in the house until frosts have gone.
Perhaps you could make bubble wrap or fleece tents over them if they need some more warmth?

Leeks go straight in the greenhouse once they're up, they love it.

I've got leeks, onions, peas & beans in mine - really low temps predicted for next week so nothing tender is going out there.

On the allotment I have a grow house (blow-a-way) inside the greenhouse and the two layers of protection help, the problem is getting down there to keep an eye on everything, as above Frost Warnings for Saturday Night / Sunday Morning in the South East of UK

I'd put these in the greenhouse:
Celery
Leeks
Sunflowers
Dahlia
Carnations (still very small)
Lobelia (still very small)

My leeks have been in there from day one. I've also dahlias and lobelia in mine too. Worth keeping fleece to hand too.

My tomatoes are ready for potting on this weekend so I'm going to have to decide what to do with them as my south facing window sill options are limited this year.

Sorry to hijack your post Natalie - but I have a similar question.

I've just bought a blowaway, now I know the forecast temps here are terrible for the next few weeks so my tomatoes and chillies will be staying indoors, or at least they will at night.

BUT can my borlotti beans go in the blowaway - and if I harden them sufficiently can they stay out there? They're getting far too big for my windowsill!

**NatalieCooke** · 15-04-2016, 05:06 PM

I'll stick the leeks in the greenhouse this evening then and most of the flowers. Looks like I'll still be making trips to and from the greenhouse.
Thanks everyone!

I've got a similar problem with limited indoor sunny windowsill space, and have already put some tomato seedlings out in an unheated greenhouse.

No doubt others might say it's too early, but so far mine have been ok.

Tomatoes will tolerate cooler nights than chillies or peppers, so when I needed to make room, the tomatoes went in the greenhouse first.

An unheated greenhouse with doors closed overnight will give protection of about 5*C compared to outdoors.

I have plenty of room in the house just worried if one night I forget them. I've got a paraffin heater but it might take a lot to keep it at a constant temperature is due to the size.

**jackarmy** · 15-04-2016, 08:42 PM

My toms are just about out full time now but will be back in the bossom of the home over the weekend

**Chris11** · 15-04-2016, 08:44 PM

Natalie, if you've got room in the house, might as well keep things indoors overnight, especially with cold nights forecast this weekend.

Beans are really tender and really need to be sown much later. I have done an early crop of dwarf french beans for growing on in the GH, they are wrapped up overnight but it's with overnight temps getting really low I'm not holding my breath. If you can keep them indoors, I would.

Its a debate I have with myself every year. The forecasts here are for low temperatures, but not below freezing. I have a blow away inside my greenhouse and I cover the tomatoes inside with a fleece. So I'll be leaving them outside (I think

).

**Bacchus** · 16-04-2016, 08:19 AM

Slight frost here last night so still far too early to be leaving the chilies out over night - even the tomatoes I still bring in during the evening. It will probably be another month before I'm tempted to leave stuff overnight
