Here is a quick look back at the backyard table grapes project so far...
2008 - Planting grapevines. We planted Black Monukka variety.
2009 - Grapevines began to grow up on the wires. After waiting for the other two vines to grow, we replaced them with some Jumbo table grapes that due to poor reading comprehension, were seeded table grapes.
2010 - The grapevines grew up to the wires and began to get trained down the wires. Wasn't too familiar with trimming the lower growth. There were a few clusters of grapes this year.
2011 - With trimming the lower growth, and the vines being up on the wires, this season was the first with real fruiting. We got something like 58 clusters of grapes!
2012 - The trellis was looking pretty sad. As well, I massively pruned the trunks, down from two to one on the original plantings. Also, I removed the Jumbo seeded grapes, and replaced them with Concord. I LOVE the smell of Concord grapevines.
This is the new trellis. In construction in the photo above, and after being painted/stained in the photos below.
