![]() ![]() Summer planting: Overhead irrigate to soften the soil, amend the soil, shape beds, lay drip tape and plastic, and plant. Typical planting systems in Oregon and Washington Refer to the results of your soil analysis (see below) for the required addition of other nutrients prior to planting. Preplant nutrient applications enable better plant establishment. Preplant soil testing indicates nutrient status and soil pH (see “Soil testing” below) and what should be corrected before bed shaping and planting. Effective soil preparation improves drainage, root growth, and nutrient uptake throughout the life of the planting. Break up hardpan by ripping or subsoiling from 12 to 24 inches deep, depending on the soil type, followed by surface tillage and proper bed shaping (see Figure 2, page 3, and Figure 4). To evaluate your soil, dig pits to locate soil compaction or hardpan problems and evaluate soil quality and drainage needs. Strawberries need well-drained soil and are often grown on raised beds to improve drainage. Refer to local publications or resources for a full strawberry production guide. Although some guidance is provided here, this publication is not an all-inclusive crop management guide. ![]() Fertilizer programs do not correct for poor drainage, soil-borne disease, nematodes, insect pests, and weed competition. Sufficient strawberry plant growth and ideal nutrient uptake requires growers adjust soil properties, increase the level of organic matter, adjust soil pH if needed, and assess the potential for pest problems. The Oregon State University Extension Service agent or Washington State University Extension educator in your county can help you with any further questions, including additional resources. Finally, it explains each nutrient in detail for both June-bearing and day-neutral types of strawberries. Using soil and tissue testing and basic fertility recommendations, it identifies how much of each nutrient should be applied. This publication explains how producers can prepare a site and lay the groundwork for optimum nutrient management during the life of the strawberry field. Which application method is called for?.What source or material is best to apply?.Since this publication focuses on production west of the Cascades, any recommendations for fertility management on the east side are based on research done in other locations with short growing seasons.Īny nutrient management plan must address four key questions: In Oregon and Washington, June-bearing strawberries (see Figures 1 and 2, page 3) are typically grown in a perennial, matted-row system with overhead sprinklers and granular fertilizers, while day-neutral cultivars (see Figure 3, page 4) are typically grown in a perennial, raised-bed, plasticulture system with drip irrigation and fertigation (application of fertilizers through the irrigation system). A good nutrient management program ensures sufficient nutrients are available when the plants need them. Optimum nutrient management will not compensate for poor management practices or fix problems unrelated to fertility. The use of well-adapted cultivars and disease-free plants.Our management recommendations for conventional or organic production in strawberry fields west of the Cascades assume: Some organic growers may opt to grow day-neutral plants for one season to reduce the buildup of disease and pests and incorporate them into their annual rotations, usually with season-extension methods to increase profitability. Preplant considerations are as important for day-neutral strawberries as they are in June-bearing types. In Oregon and Washington, day-neutral types are usually grown as semiperennials (two to three growing seasons), while farmers in California, Florida, and North Carolina usually grow them as annuals. Day-neutral strawberry plants flower and fruit throughout the growing season, providing a steady supply of berries that makes them ideal for the fresh market grower. We’ll refer to this type of strawberry as “June-bearers.”įarmers in Oregon and Washington are increasingly planting day-neutral strawberries. This type of strawberry is harvested over a three- to four-week season from mid- to late-May through June. This guide explains nutrient management for June-bearing and day-neutral cultivars - the two types of strawberries typically grown in the Pacific Northwest.įarmers traditionally raise June-bearing (or short day) cultivars for the processed market. Strawberry growers in Oregon and Washington raise fruit for both the processed and fresh markets, using both conventional and certified organic systems.
