Thanks for contacting us about growing tomatoes. Any disease resistant tomato can be grown in Weld County, and do well, provided they have the correct growing conditions. There are many to choose from, and new ones are constantly introduced, so I encourage you to shop at a good, local nursery and choose from their selection. Flavors vary; some are sweeter, some more acidic. When they become ripe varies; look at ‘days to maturity’. Size varies; do you want big slicers? They take longer, so you may want to add a smaller, early variety to have fresh salad tomatoes before then. All tomatoes range widely in size, shape, flavor and color. Again, just about any can do well here with the right care. Are you growing them in containers? There are now many hybrids that have been developed for compact spaces. A few general recommendations are listed below.

You are wanting disease resistant varieties. Heirloom tomatoes are not disease resistant; you may want to avoid them. So, that means choosing hybrids that have been bred for resistance, and that is indicated by the “funny” letters after the tomato name (like V,F,N, TSWV). So, look for hybrid and VF (at least) on the labels.

Some recommendations that are easy to find (these are all red tomatoes):

1. Cherry. Sweet 100, SuperSweet 100
2. Paste. Some Roma varieties (an heirloom that does well here is Amish paste – might be worth a try!).
3. Slicers. Celebrity (my personal favorite), Big Boy, Early Girl, Big Beef.
