“Timely Viticulture” Balanced Pruning 2 dealt with the timing of pruning relative to dormancy, deacclimation, and bud break. The best thing to do is to try to delay pruning as long as practically possible. If you could accomplish all of your pruning in the last two weeks of March that would probably be best, although that is typically not enough time do to the size and labor limitations of most commercial vineyards.
If the vineyard is cordon/spur prune, one technique you can utilize to save you time and money is to “pre-prune,” “double prune,” or “rough prune” before you “finish” pruning down to your 2-3 bud spurs.
Double pruning vines is desirable for varieties that are susceptible to winter injury and/or prone to early frost damage.
As much as possible, prioritize your pruning schedule according to the relative susceptibility to winter injury of each variety.
