Soil solarization is a pre-planting practice to reduce weed pressure by trapping solar energy using a transparent polyethylene film to heat soil. Soil solarization has been successfully used in regions with high solar radiation. The purpose of this research was to determine if soil solarization under Pacific Northwest conditions could...
Weeds reduce the value of nursery crops. They compete with crops for nutrients, light, and water. Some vine weeds climb nursery crops, requiring excessive labor for hand removal. Most serious are perennial weeds, which can be harvested with nursery crops and infest the field or landscape where they are subsequently...
Experiments were conducted to determine the influence of cultural management practices on weed growth in nursery containers. Experiments 1 and 2 evaluated the effects of dolomitic lime rate and application method on substrate pH, creeping woodsorrel (Oxalis corniculata L.) establishment in containers, and growth of azalea (Rhododendron ‘Rosebud’) and pieris...
