Allotments 4 All

Running out of heated space and am wondering when it is safe to sow seeds in an unheated greenhouse.  Alternatively, if seeds are germinated in a propogator, when can they be placed in the unheated greenhouse?Thinking specifically about Marigolds, Cosmea, Dahlia, Butternut Squash, Dwarf Beans,  ???

I still reckon it's too early for Squash & Beans. But you should be able to sow anything in a cold 'house. I'm risking some outdoors now that the soil is at 42F

Flowers?  Don't do flowers!

our marigolds are in the unheated greenhouse, the dwarf beans are in the poly border, covered with fleece  ;D

What about moving tomato plants (about 4" tall) out to a cold greenhouse. Still too soon?

we've put ours in trays with a plastic cover (69p from homebase) , covered with fleece and put in the greenhose as well, they don't seem too bad, we just uncover them during the day  :)  sorry, the cover's 69p  ;D

Don't quote me,  but my toms go into the cold 'house at the end of May.

I take toms out every day to the cols g/house and bring them in every night, forget some recently and they survived. If the temp does not drop too much I am sure they would probably be okay

I have a frost free greenhouse. I start most of my seeds off in the house, next to the patio windows. Once they have germinated, they are moved to the greenhouse - they all seem perfectly happy there!

Yes - all is possible. However, I lost a row of toms in the cold 'house in June!!

And things like Cucumbers "do NOT like it below 50F".

My green house is not frost free, but Marigolds are fine there, I moved them in January, Cosmos was moved about 3 weeks ago, they are also fine. Tomatoes, peppers and eggplants are in Wilko polytunnel inside the green house, so good so far, some of them were there since February. The conditions are still not quite good and last week I forgot to move some tomatoes into the polytunnel, left them just in the greenhouse, so 3 out of 4 got frost bite, but I can't keep plants at home, my husband goes mad at me, he can't stand soil in the house.

Have found this thread really useful thanks.  I think that I keep my toms on the back bedroom window sill too long and am going to try risking a few in the greenhouse... :)

Hi all,  :)

I have to make the best of what I have, That means everything in pots
and trays will be started in the unheated greenhouse. I put some new dahlia tubers in some boxes of leafmould to store and they have started to grow.
I have squash and toms in covered trays and there is germination going on.
(I didn`t examine each tray).

My greenhouse should be undisturbed all week
so the heat stays in. (The door was open yesterday I don`t know if I left it open all week or if someone is poking around, the dalhia shoots survived).

I will be doing a lot of planting over easter because thats when I have the time.
If seeds grow and survive I`ll be off to a good start and if not I`ll just start over.

Best of luck to us all, Col

We're away for a week over Easter so think I'll wait until we get back to move stuff out, just in case we get a frost.

Again I think it depends largely on what you plan on sowing, let the packet be your guide! at least for temperatures rather than say the sowing times!

Generally;I would say that any seed that can be sown directly into the ground would be suited to cold greenhouse germination.

If a minimum temperature is stated on the packet then it is wiser to follow these temperature guides.

hello
We have allsorts growing in our unheated greenhouse
sprouts, cauliflower, cabbage, lettuce,onions, leeks, peas, beetroot,
sweet peas and marigolds. All are doing great. ;D
The only heat in there is the sun
Hope this helps. We are in yorkshire by the way :D

Not far from me, then, debbie- that's encouraging!

I have germinated  broad beans , sprouts ,cabbage , leeks and caulies  in my cold house ...
I would say its too early yet for tomatoes ,cucmbers etc ..,,
Cheers, Jim

Hi Manic, did you germinate your marigolds in the cold GH or indoors?

inside, just until they were showing then straight out to the greenhouse  :)

thanks - will try the same
