Determining the Effect of Biodegradable and Living Mulches on Annual Weeds and and Growth of Newly-planted Blueberry

In a newly planted blueberry trial, ‘Draper’ plants were transplanted from 1-gal pots into the field in March 2015.  Greenhouse-grown living mulch plants, creeping buttercup (Ranunculus arvensis L.) and sweet woodruff (Galium odoratum (L.) Scop.), were transplanted to a density of 1 plant/ft2 at the same time as blueberry.  Other plots were treated with 5 […]

Weed management in establishing an organic wine grape vineyard

Weed management in new wine grape vineyards was identified as the primary constraint to organic production in the region. This project investigates weed management options for establishing an organic wine grape vineyard and includes 5 treatments: standard weed control of rototilling and mowing, the Wonder Weeder, and three grain/legume cover crop treatments. Local growers and […]

Organic Transition Rotations for Northwestern Washington

Two three-year rotations are being investigated for suitability for organic transition in northwestern Washington. Cover crop growth was greater and resulted in better weed suppression during 2004-05 than in 2003-04. Common chickweed was the major winter weed species, accounting for 90% of the total weed biomass during the first winter and 75% during the second. […]
