All wrapped up...........hopefully!!!!!!!

[Snadger]

I have had my toms,peppers,cukes and sweetcorn in the cold greenhouse for the last couple of weeks. It has got down to freezing point but luckily they have survived and appear to be thriving.

I know of one person on our plots who has lost all there toms to frost!

The forecast is now for frost and SNOW!

Wrapped my 'softies' up in the polystyrene stuff you put under laminate flooring and have them high on the greenhouse shelf (Groundfrost protection?) and hope they survive!

We shall see!

Oh snadge, I'll be watching this with great interest. I have more plants than I have room for in the conservatory but am afraid to put them int the greenhouse.
Wish I had your belief that they're going t be OK.

How are they this-morning?

How are they this-morning?

Don't know..........I can't see any white frost or snow out of the window and I ain't been to the allotment yet?

I always presumed that in greenhouses the floor was the warmest place at night and nearer the top, the warmest during the day.

After potting on my toms, I had a couple spare, so I have planted them outside and covering them up in different ways, just to experiment with what survives.

I've lost some before in my greenhouse and I am in the belief that it is either a micro fraction of a degree which makes the difference, or how long the cold goes on for.

If you've got a min max thermometer, that would be interesting to know.

I assumed 'ground frost' was so named because it hugged the ground?

I have one max/min thermometer but to try out your theory I would need two!

I always put the most delicate plants on shelves that go across the end of the GH at about head height. They seem to be better protected but perhaps it's just my imagination. I've had melons and courgettes there for weeks now.

Well my theory was, that it's the ground that stores most of the heat from the day, so I presumed that was where most of the heat was.
Looks like I may be very wrong from patchninjas post
I suspect it depends on many things, how well the greenhouse is insulated, what the base is made out of and what weather was had during the day.

Mind you, what I've done in the past, was fill the floor with rocks and then drape fleece over the whole lot, rocks and plants in the border. The floor is definitely the warmest place then. But you have to be there in the morning to remove it.

I put 4 courgettes into my cold GH 1 month ago at waist height, as I was told I had planted them a month early. Due to lack of windowsill I had nothing to lose. They seem to be doing well, although it is my first attempt. All 4 plants appear to be growing flowers. Just in case I have sown some more today in the window.
Again due to lack of space because every tomato seed I planted came up (32 in total) I shoved some out of the way about a week ago on the greenhouse floor, again they appear ok ( if not looking stronger than the ones in my window )
My Min Max thermometer has shown up to 30 and down to 3, How are these plants surviving?

-2 in my greenhouse last night, how are yours Snadger?


The tom I had in a plastic bottle cloche, with a cardboard box over the top survived, the other ones with nothing and just a cloche, died.
