90 Days. Michael’s Portuguese Monster tomato is one of the most consistently huge tomato that we have ever grown. So many of them approach the 2 pound mark, even when the season is winding down. Pink slicers are on the sweet side, delicious and full flavored. Vines are thick. tall, vibrant and sprawling. if you like huge tomatoes, put this one on your list. A good selection for Market sales too!
