Foothill grape growers are invited to a Grape Pruning Field Day on Feb. 13, at 1:00 p.m., at the Sobon Estate Vineyards, 14430 Shenandoah Road, Plymouth, Calif.

The guest speaker is Dr. Andy Walker, professor, University of California viticulture and enology department. Dr. Walker will demonstrate pruning in spur pruned bilateral cordon trained vines and spur pruned head trained vines of several varieties.

How pruning affects “vine balance” will be discussed, plus the impact of last year’s spring freeze.

If it rains on the scheduled field day, the event will be postponed to Feb. 27.
