I have a packet of Cucumber seeds. It suggests using garden netting to ensure more slender and smooth fruit. What is Garden Netting and how does it help?

Cucumbers can be grown on trellises, netting or other types of supports. The thought is that the fruit will develop better if it's hanging vertically, and the plants won't take up as much room if the growth develops up instead of down. Garden netting is a mesh fabric that is used for growing sweet peas or any other vining type of plant on. It's available in different sizes and with different sizes of openings, depending on what you're using it for.
