I'm growing Sweet Million tomato plant in my background. On the instructions it says "The plant has a strong central stem that should be tied to a stout cane as they grow. Pinch out all side shoots when they reach 2.5cm in length."
Does this mean remove every shoot off the main stem, or just slice it off at the end when it is 2.5cm? Do you pinch out the side shoots which come off the side shoots?
Sorry for the basic questions, and many thanks in advance for your help.
