At present date, we are not able to be a presence at the farm everyday and the wildlife knows it. in southern maryland, a vine's most feared predators are the deer and small critter, looking for tasty tendrils and succulent young vines to strip down to nubbins. later in the year, we will worry about birds picking at the grape clusters. don't even think of the september drunken hornets!
all vineyards seem to have a common critter problem. a few have dogs patroling the vineyard fields, and others employ noise canisters to scare birds. some try bad smells for the furry critters and deers (home gardeners will know what i'm talking about--irish spring soap, blood meal sprinkles, rotten eggs and peppers sprays). others will invest in electric fences--the very same that takes care of the common suburban canine.
