Growing beefsteak tomatoes in pots

Due to a late start and also to try and protect against blight I’ve decided to grow some tomatoes in pots in my back yard. It gets a good amount of sun. I already do that with cherry tomatoes, but will give costoluto Florentino a go as well. I’m going to try and get as big a pot as possible. I also have some good quality horse manure but other than that is there anything I should do? Thanks for any tips!

Exactly the same as News!

I've for many years grown my Marmande large tomatoes in 9 inch diameter pots (1 plant per pot) with about 6 inches deep of compost that was a mix of Verve multi purpose compost and my homemade bin compost.

That area got good sun and I kept them watered well with a weekly tomarite feed and a fortnightly top up of my homemade seaweed feed during flowering and tomato growth.
I have though this year made a permanent raised bed for them, so hope they grow as big and as well as they have done in the previous years pots.

I'm growing San Marzano again, and while they're not a beefsteak, they get pretty big by the end of the season.

I put two plants in a 10" pot, in a water tray, (so it's eight plants per tray), and while they may look crowded, the yield is pretty good for the outlay - and of course the space! They also tend to slow their ripening as the leaves do hide quite a lot of the plant at the rear of the pot, so the season goes on a little longer, which is great for an Autumn crop!

Feeding and watering is a 'must' though!
