Sleeves around new vines are held in place by thin metal stakes in the ground that hook over the lower support wires.
The new vines have what looks like a red waxy coating on them which dissolves away as the vine grows. I should have taken a photo of that, but I didn't. To protect the new vines from hungry animals and cold weather, they are planted inside a foot-high sleeve. The sleeves will stay on for a year or so. Next spring, as the vines start to leaf out and produce tendrils, they'll poke above the sleeves, reaching for light. I'm happy to see growers investing in their vineyards, especially the ones around us.
