- Plant on beds raised 8 to 10 inches to improve drainage, or use drain furrows.
- In home gardens or small plantings, raise the bed 15 inches.
- Preplant soil solarization has been helpful in reducing populations of certain soilborne pathogens and weeds in western Oregon.
- Place clear plastic (preferably anti-condensation film) directly on smooth, rototilled ground, which has been irrigated to field capacity and then allowed to drain for 1-2 days.
