With the tease of Spring for a couple weeks in early February, it’s not difficult to think Winter is over and done.  But God has a way of letting us know he is still in charge.

April 1, 2010. Snow Cap on Mt. St. Helena.

Snow in San Francisco!! Perhaps on Friday or Saturday that could happen.  I am expecting to see snow ringing the Napa Valley by the weekend, but that is still only the end of February.  In 2010 we had a snow cap on Mt.  St. Helena on April 1st, and it wasn’t an April Fools joke.

The good news for now, is that the vines are still dormant, although it won’t take more than a couple of days at 75 degrees to see buds start to pop into this years new growth.

You may have seen a lot of  vines in the Valley this year with “long haircuts”.  Our Cabernet was “long” pruned a month ago, leaving canes 12 to 14 inches long.  Just as we see signs of bud swell this spring, we will go back into the vineyard and “finish” prune the vines, selecting the spurs to remain for this year’s crop.

Wicker Vineyards Cabernet Vines Waiting For Final Pruning Cuts

This buys us a couple of benefits.

First, it allows us to make the finish cuts just as the shoots start to grow.  Without all the long brush to pull from the canopy, there is no danger of breaking off the tender new buds.  This gains us as much as a week or ten days of frost protection by delaying the bud break.

Secondly, this practice helps us control Eutypa fungus infections.  The free fungus spores are released by rainfall, and infect the vine through the fresh pruning cuts.  When we make the final cuts, any early, wet season infection by Eutypa spores is trimmed off before it has a chance to work its way into the main structure of the vine.  This is a great example sustainable practice farming, preserving vine health without the use of chemicals.
