I grow my Tomatoes using a technique called Ring Culture, and you can see our expensive watering aids that have been added this week.
Top of the line, no money spared here folks...
Yup, exactly as it looks. Old milk cartons with the bottoms cut off and planted beside each plant. This allows for the watering to be better targeted to the plants. Also, tomato plants are shallow rooted so if you water them every day on the soil you was a lot of nutrients away from the roots, so in turn you have to feed them more. This technique with the milk cartons allows for the water to be slowly fed to the roots in a more controlled manner....
Our companion plants are Marigolds and are planted inbetween each tomato plant.
