Tomatoes thrive in high tunnels

Proper Spacing and Training • Makes for healthier,
more productive plants• Greater yield• More efficient work

It is easy for things to get out of hand

We have learned a lot about training and pruning slicing tomatoes
![Page 6: Pruning for Productivity - Cornell University Tomato Prunin… · Pruning for Productivity High Tunnel Cherry Tomato Trial 2016 Cornell Willsboro Research Farm. Amy Ivy, Eastern NY](https://reader033.fdocuments.in/reader033/viewer/2022050218/5f63a5a9de30185548444e3d/html5/thumbnails/6.jpg)
Cherry Tomatoes are challenging to train
![Page 7: Pruning for Productivity - Cornell University Tomato Prunin… · Pruning for Productivity High Tunnel Cherry Tomato Trial 2016 Cornell Willsboro Research Farm. Amy Ivy, Eastern NY](https://reader033.fdocuments.in/reader033/viewer/2022050218/5f63a5a9de30185548444e3d/html5/thumbnails/7.jpg)
Cherry tomatoes are the first to ripen for earliest sales.
