A colorful mixture of cherry tomato varieties is a popular item at farmers markets, farm stands, and supermarkets. Creating a rainbow mix elevates the humble cherry tomato to gourmet status and calls out for a taste comparison. Customers who buy a cherry tomato mix once will be back for more because these varieties really do offer different flavors as well as colors, and all of them are delicious.
At Johnny's research farm, we grew a mix of cherry tomato varieties that are all about the same size and ready to harvest simultaneously. The varieties we chose for our suggested mix are 'Black Cherry', 'White Cherry', 'Favorita', 'Sun Cherry', and 'Sun Gold'. All are indeterminate varieties and range 58 to 65 days to first harvest. All the fruits are about 1 1/4" in diameter, however, any selection of cherry or grape tomato varieties can be put in a mix.
The tomatoes were grown in a high tunnel with drip irrigation underneath ground cloth to eliminate weeds. Plants were spaced 12"to 14" in the row and pruned to create two vines. Suckers were pruned off the plants as they grew. String was tied to the high-tunnel purlins, and the vines were trained onto the string utilizing tomato clips. If you plan to keep any indeterminate tomatoes all season in a high tunnel, you should leave extra string after attaching it to the purlin. Tomato plants can get so tall you will need to let the strings down late in the season to harvest the fruits - unless you want to pick from a ladder.
In the Johnny's trial, the high tunnel tomatoes had few pest or disease problems. Nor was pollination an issue; just walking through the high tunnel vibrates the plants enough for them to pollinate themselves. The variety 'Sun Gold' is prone to cracking if it gets too much moisture, so we put a valve on the drip line to those plants and reduced the amount of water they received relative to the other varieties.
Labor is the biggest issue with cherry tomatoes. They need to be picked every day or two for maximum yield, which makes them time-consuming, pound for pound, compared to regular tomatoes. But, they are certainly an eye-catching produce item that pulls in customers.
