We have cut back this year with just 40 .. when frozen they will keep us going right through until next summer.
We are on the south coast and have an earlier start than the most of the country when it comes to planting outside (fingers crossed).
One dwarf french bean without a doubt will produce more beans than a single climber. I have had plenty space to grow them, but having grown both varieties for a number of years, I have opted for the dwarf variety due to the sheer amount they produce.
Maskotka is a small shrub type tomato suitable for outdoors that is blight resistant. We suffer with blight, as it as blight transfers across from potatoes quite readily. Every plot holder grows potatoes, so we can't avoid it.
In France surely you are way ahead of us with the growing season.
My brother in law lives near Le Mans and he sends us pictures of what he has grown and he is at least 3-4 weeks ahead of us.
If you want some large toms .. last year I grew some Cour De Bois toms, they averaged around 300gms each. The only problem was they broke the canes and string supporting them. Amazing for breakfasts and steak meals !
