Maybe it’s too late to implement some of these tips this season, but there are a few tips that you can do now to increase the productivity of your tomato plants. As far as the other points you can keep them in mind for next season. For next season, you can ask a local farmer or expert about the best tomatoes to grow in your area, he might even give you a tip or two from his local experience. Other pieces of advice include
- Erect a cage around each individual plant.
- Protect the tomatoes from the wind by covering the cages with floating row cover.
