Abimars Thicker Garden Insect Mesh Netting, 2 x 10m Ultra Fine Plant Mesh Cover, Durable Barrier for Insect & Bird Protection – 30% Shade Net for Veg Patch

In the heat of the summer, This super fine black mesh netting provide 30% shade Sunblock which helps keep them cooler, preventing bolting and drying, and UV-resistant, and giving the extra advantage of helping to reduce heat on strong sun, hot days, to reduce watering frequency.

The fibers of this mesh do not move around(Each wire is fixed), It will not get holes if you pull or poke it, The cross threads are attached so if it is cut to another size, the cut is clean and it is regular and not frayed, the edges will not unravel, You can cut it freely into the size and shape you want.

You can water the plants without having to remove the netting, which is also convenient. I would recommend using some sort of support system for the netting (like a trestle or support stakes, etc.), that way the netting is not laying directly on the plants(the netting is super lightweight - 45g/m², but still could cause plants to bend and break their stems).
