Are San Marzano tomatoes hard to grow, what is the best way to grow them in a big pot?
Full Sun: Like all other tomato plants, the San Marzano variety will need at least 6–8 hours of daily direct sunlight. While they will grow in slightly less, the yields and fruits themselves will be smaller.
Fertile, Well-Draining Soil: These plants are heavy feeders and will require the in-ground gardener to amend existing soil with plenty of compost or aged manure.
Novice gardeners will have no problem growing San Marzano tomatoes. Other than being a bit bushier then most other indeterminate tomato varieties, they will require the same basic care.
Hi, I'm growing San Marzano tomatoes (from garden nursery plants) for the first time. The plants are healthy and loaded with large fruit that is just starting to ripen. I picked the first one a few days ago and when I cut it open it was kind of hollow and dry inside. I picked a green one and it was the same - not much meat to it. Is this how they are supposed to be? Thanks.
