Pruning Time is Here

My husband and I wanted to get a head start on pruning this year. March has been a brutal month with major snow, wind and rain every week, but this week temperatures are in the 40's so we began our pruning on Saturday, March 24.
This year, we have 6,000 or so plants to prune so it will take a while. This got me to thinking about when we pruned in previous years and how long it took us:

Year	Month/Dates
2014	April 17, 18, 20, 21, 22, 24, 28
2015	April 12
2016	March 1-3, 6, 8, 11, 16, 17
2017	April 10-13, 15, 16, 19, 23

During 2015, we only had approximately 600 young plants to prune so it didn't take us too long. During 2016 and 2017 we replanted nearly 6000 vines. The plants that we planted in 2016 are now in their 3rd leaf so there are many plants that have canes that we can lay down.
We began our pruning duties on Saturday. Here is the task we have ahead of us:
