Plants in greenhouse - killed by cold?

[colonel]

Hi there,

I have just been in to my greenhouse and noticed that quite a few of my young plants in there; aubergines, courgettes, squash, cucumbers are all limp and look in quite a bad way.

Now I think the temperature must have dropped quite a bit last night so I think it must have been the cold that has affected them like this.

Will they revive? Is there anything I can do to give them a boost/ helping hand to bring them back or are they goners?

Any advice about this would be welcome. I am quite new to growing veg or anything else for that matter so am at a bit of a loss as to what to0 do with these plants. Should I just sow some new seed and cut my losses with the others?

Thanks in advance for any help.

Stay safe and happy growing

I've no idea what your overnight temps are but I don't leave tender plants in the GH overnight if its forecast much below 10C. Last night the forecast was 8C so I covered the big pots with bubble wrap and brought the seedlings indoors.
Yours may recover ...........or may not? Still time to sow more.

I'd start again, they don't usually recover
They like the temp to stay at 10C or above before they can be permanently in the greenhouse. A lot of us, that can't heat their g/house, put things out during the day and bring them in again every night if the forecast shows temps under 10C.
Just as an example - I can't usually leave stuff in my g/house 24/7 until the end of April, beginning of May here in the SE corner.

It went down to 6c last night, a few of my small butternut squash were looking a bit limp first thing. I gave them a bit of warm water and put the heater on low and they have picked up already, so it’s worth trying. I have 4 pumpkin in the poly tunnel with 3 or 4 fruit already forming, they also survived with a net curtain draped over them. So fingers crossed.

Yes the cold will have killed some of them, it's possible a few may revive.

Main advice is to bring the rest in to the house this afternoon as the forecast is for frost tonight. A lot of plants can stand cold weather but there are many that can't - if you are unsure which ones can't, then either google them or ask on here.

Learning by experience can be a costly business, but we've all done it - happy gardening :-)

I think it was really quite cold last night, though I haven't got any idea how cold. But I can tell some things were a bit limp outside in the garden. Luckily I haven't got anything out there that tender.

Ghexton, did you see this? I know you're keen to get things out lol

Sorry to hear that colonel, I have been having this very thought the last few weeks and aired in the side of caution.

Check your forecast for tonight - mine is down to 2C so I'll be bringing in/wrapping up. just in case.

I've had my tomatoes in the greenhouse for a week. They were fine last night (5c). They are inside a blowaway in the greenhouse for tonight which are wrapped in fleece. It's forecast for 0 degrees here. Very risky so fingers crossed. I don't have room to bring them in really. Might go over and light a few candles later on. I wouldn't be risking my chillis, peppers and aubergines tho.

My forecast says 1c for the early hours of Tuesday nothing tender left in the GH.

I've just bottled it and took my van to the allotmemt and got all my toms. I'll probably sleep better tonight haha.

I would rather have leggy plants than dead plants, so they will stay on the windowsill for the time being.

I brought everything back in last night as the forecast was 5 and the little blow-away doesn't give much protection - I assume it could be 2 degrees lower than predicted.
So of course it only fell to 9 degrees, but better to be safe if you can.

[nickdub]

I left mine in the PT but put them all together on the bench covered up with a thick blanket - ground frost here last night - will be off to see how things got on and check my max/min thermometer.

[PyreneesPlot]

I use my little blow-away as a halfway house between indoors (start of April) and the final planting in open ground (start of May) but having put a thermometer in there last night I see that it was only two degrees warmer than outside.
But I guess it gives protection from the wind and rain, and a more gentle introduction to the slug, snail & vole population.
