Tomatoes for north-facing garden

This is my first ever post...
I am a keen but inexperienced gardener, dividing my time between London (small north-facing plot, mostly used as a football pitch) and Dorset, where I have a couple of acres.
Unfortunately most of my time is spent in London.
I am starting to think about tomatoes, which will be grown in grobags against railings beside the house, facing north, with quite a lot of light but not much sun - we get some from the side in the morning and evening.
The challenge is getting them to ripen before blight sets in.
What varieties should I choose? And when should I sow? I plan to start them indoors and then move to a large cold frame until frosts are over.
Hugely grateful for suggestions and advice.

 

Welcome to the forum! I have totally different growing conditions and I am a perennial novice. Pretty much useless but

@Zigs wakey wakey. A neighbour needs some help please!!

 

There is a variety called Sub Arctic Plenty that is quick maturing and cope with cooler conditions.
It is also a bush type so you don't need to pinch out the side shoots.

 

Sub-Arctic Plenty certainly sounds like the biz. Thank you for the suggestion!
Any other ideas? I'd like to combine tomatoes that look like tomatoes with some that definitely don't.

 

Welcome to Gardeners Corner

There's a 42 day tomato available here

I've grown other varieties from their selection, there's a 58 day one, but i've forgotten the name, maybe @Vince or @JWK will remember.

 

All the prices are in dollars. Is that cos it's an American site?

 

Yep, it's in someplace called WI according to the packet

 

Don't you have to pay import duties on stuff from the US? My mate bought a leather wallet from a US based online shop. He bought it because it was cheap. But then he got a demand for some disproportionate sum, for import duty.

 

Not sure about seeds, @Vince bought em and sent them on to me

 

They don't ship to the UK. I recall Vince having a contact in the USA who bought tomato seeds and then personally sent them to him in the UK.

This UK based supplier sells 42 day tomato seeds TOMATO 42 DAYS SEEDS | New & Featured Vegetables

Some info 42 Days - Tatiana's TOMATOBase



P.S. I'm not entirely convinced that 'low temperature' or 'fast maturing' tomatoes are necessarily going to perform well in shady conditions. I thought the rule of thumb was an absolute minimum of 6 hours sunshine but ideally 8 hours sunshine per day.

 

JWK it is very interesting to hear you say that. This will be my third year of tomatoes in that location.
The first year I grew Sungold and Black Krim. Blight hit before ripening, though I managed to salvage enough for a few jars of green chutney.
Last year it was Sungold, Black Krim, Costoluto Fiorentino, Gardeners Delight and Red Alert.
Sungold ripened ok but not brilliantly, likewise Gardeners Delight. Got a few Red Alert. The other two were disappointing.
However, the weather was cold until mid-August and I was a bit haphazard with my pruning regime. Hoping to be better on top of things this year!
Thank you for the Bordeaux Mixture recommendation!

 

So grateful for the warm welcome and all the helpful suggestions!
Bombproof is probably the way to go.
