Is is okay to grow outdoor toms in an unheated greenhouse?

[mew]

Hi
I have some tom seeds (cant remember the variety - not at home to double check) but I know they are an outdoor variety. Just wondered if its okay to try some in the greenhouse or am i best sticking to outside?

I attempted growing alicante last year in the green - total failure. They leaves became very diseased and im not 100% sure was it was. Stonehead I think found the problem to be bacterial leaf spot and Im not sure how it happened or how to avoid it this time albeit im going to try them outdoors, but I just wondered how folks faired at growing outdoor varieties inside too?

Thanks

most people I know got blight on their tomatoes - it could still have been that.

yes I grow gardeners delight in a greenhouse, yet often said to be outdoor type.

Since no tomatoes would grow outdoors up here - every tomato is an indoor variety!

yes in the greenhouse would be perfect, but saying that , as ina says, unless to get a fantastic yr then there isnt much chance of much of a crop up here from any tomatoes

You can be fairly sure that the disease is still lurking in your greenhouse if you haven't treated it.

Every year I wash out the greenhouse and polytunnel with a bought soluition that kills bacteria and disease. There's an organic version too. Costs abot £7.99 a bottle but will last for years and many applications. I apply it with a sponge mop to the glass surfaces.

I would definitely recommend this prior to growing toms in there again.

what is it called, the organic one as well if you can recall, ?

I didn't buy the organic one because the other one had been recommended and my greenhouse has no open soil in it so it couldn't contaminate the plants/soil etc. I will check the name on the bottle when I am next at the allotment. Also I will have a look at the organic one when I am next at the garden centre. It may have been a "growing success" one.
I've noticed that Jeyes do a greenhouse cleaner for less than £4. It's insecticidal and fungicidal but not organic.

A tip for everyone who grows tomatoes in a greenhouse or polytunnel. If you water them with rainwater, be very careful not to get any on the leaves or stems. Blight is spread through air-borne spores and during the blight season these will be present in rainwater. If you then get this water on the leaves you will get blight for sure.

Oh, that's a great tip. Thanks Marc

The organic cleanser is called Citrox - I use it every year to clean my greenhouse and polytunnel and to wash out my pots, trays etc. It inactivates most fungal spores (including blight).
