Persimmons (tomatoes) grown in greenhouses generally use herringbone frames, which have good stability and are easy to manage.
How to build a frame:
Use thicker, harder bamboo poles to build a herringbone frame.
The herringbone and the ground form a triangle, which is stable and can be tied with eight vines.
Another type of shelf is a herringbone shelf at both ends of a row of tomatoes.
Use a thicker bamboo pole or steel pipe to set up a horizontal bar in the middle. One end of the rope is tied to the horizontal bar, and the other end is used to hang the tomatoes to grow.
