I just ordered ten of these bags. The netting they have here for potted plants its excellent. They have ‘thermal’ for winter, and anti-insect for summer. The photo has a large tropical tree behind it so the shot isn’t clear. these would not be hard to make!
The fabric is a supple, yet sturdy fine mesh. If you take care of killing the eggs with appropriate sprays your trees will not need individual bagging. Let me know. The source is Amazon France. They will be here next week. I will let you know. Mrs. G
They are made especially for potted dwarf fruiting trees like mine.
