BUSH OR CORDON?
All San Marzano tomatoes are best grown as cordon type tomatoes. When growing them outdoors we would recommend limiting them to 3 or at the most 4 trusses depending on how much sun you get in your area of the UK.
APPEARANCE AND TASTE OF SAN MARZANO TOMATO
San Marzano Tomatoes from our allotment
San Marzano are without doubt the best tomatoes for sauces, their combination of flavour, meaty texture and very small amount of seeds makes them stand out above all the other varieties. As you can see from the picture below, these tomatoes do vary in size and texture.
You may think with all that going for them that they won’t do well outdoors in the UK but the opposite is true, they do very well. We recommend the variety San Marzano Redorta because it does better than other similar types in the UK.
This is a vigorous grower and will most definitely need support. Limit the plant to 3 or 4 trusses when grown outside and remove foliage which cover any of them to give maximum exposure to the sunshine.

Tomato Question and Answer
SAN MARZANO TOMATOES
By David Marks
There are several slightly different varieties of San Marzano tomatoes and there’s not much difference between them. Our recommendation though is for San Marzano Redorta. It’s just that little bit earlier and has slightly larger tomatoes compared to the other varieties.
This is primarily a cooking variety, superb for recipes which require passata or any type of tomato sauce. It’s a meaty tomato with lots of body and has excellent taste as an eater. It’s well suited to growing outdoors in the UK and also in greenhouses.
