9. n iastate edu Wine Resources marketing htm Weed Control Options in the Vineyard Poor weed control is the number one reason people fail to maintain or establish productive vineyards in Iowa I have heard this same remark from many vineyard professionals I also agree with them Weeds are very competitive There are all kinds of weeds that compete with crops Most research has shown that the typical summer annual weed that germinates in the spring will consume water and nutrients 3 4 times faster than the crop they are competing with Another weed many vineyard operators fail to control is grass sod Deep rooting grasses like smooth bromegrass tall fescue and orchardgrass have no place in a vineyard I always recommend that people kill these grasses completely before establishing a vineyard My standard recommendation for seeding the aisles is to broadcast approximately 50lbs acre of common bluegrass for vineyards in Iowa and keep a strip approximately 3 feet wide under the trellis wire free of any plant growth I like bluegrass because it is shallow rooted less competitive will provide a good winter hardy sod between the trellis rows and goes dormant in July amp August when water use becomes critical for the grapes Yes but why do some productive vineyards have sod growing right up the grape plants This is a common question I often hear There are instances not very many where grass sod is sometimes used to hold back the vigor of mature very

13. vigorous established vineyards Here are some common options used for weed control in vineyards Organic Mulch works well for annual weed control if applied prior to germination The most common organic mulch products being used in Iowa would include small grain straw wood chips and old hay Re application each year is the norm and typically a 3 inch or greater thickness is needed to provide weed control Clearing the mulch away from the base of the plants each winter is often advised to keep rodents from setting up house and girdling the plants These materials should not be incorporated into the soil because of the nitrogen deficit that would occur as the micro organisms take nitrogen out of the soil to breakdown the high carbon mulch materials Synthetic Mulches made of a plastic fabric are sometimes used in vineyards Typically they are installed during the establishment and then taken out later after they start to degrade from ultraviolet light and mechanical damage Most maybe all of the vineyards I have visited that started out with synthetic mulch advised against it Spending an hour or more removing the fabric out of the underside of a mower deck has been a common story theme Cover Crops can be used to reduced weed growth reduce soil erosion and help the grape plants to harden off early in the fall I normally recommend oats spring barley spring rye or spring wheat be planted in mid August These spring crops will help suck up excess m
