You can sweeten your tomatoes on the vine by using a little less than 1/4 cup of baking soda and sprinkling it around your tomato plant.
- Test your soil first – if it’s already alkaline (a pH above 7.0), this could harm your plant.
- Test on one plant first – give the test plant about two weeks and note any differences. If it’s doing well, proceed to do this to the rest of the plants
- a little less than 1/4 cup about 2″ away from the stem when you’ve transplanted the plant
- once again when the plant is about 1/2 grown
This neutralizes the acids in the soil, bringing the pH higher. This also works when you’re canning the tomatoes, sweetening the tomatoes without adding extra calories (use 1 tsp per 20 tomatoes). Too much baking soda will alter the flavor. Also, skim any foam that rises to the top.
