San marzano tomatoes

I was blown away by the quality and carcareful packaging. Opening that box and smelling that fresh tomato plant sweet smell was amazing!! These plants were fresh, the soil was still moist, so carefully packages! I am smitten with growjoy!!!

San Marzano Tomoto

I purchased tomato plants last year and loved them. The plants are packed well and the plants are healthy upon arrival. I got a great harvest last year and by the looks of the plants, I should get another one this year. Order early, they sell out fast.
