Fertilizing
Strawberry plants that have sufficient nutrients are growing well and have healthy green — not pale green or yellow — leaves. Your strawberry plants will need fertilizer in the planting and establishment years.
There are many types of solid (granular) and liquid inorganic and organic fertilizers available. Most all-purpose garden fertilizers or organic products contain phosphate (P source) and potash (K source) as well as nitrogen (N). Some, such as feather meal, also contain calcium (Ca). Fertilizer sources range considerably in their nutrient content. For example, common inorganic fertilizers available for the home garden include 16-16-16 (16% each of N, phosphate and potash), 20-20-20 and various slow-release sulfur coated urea products.

Organic sources include cattle manure (0.6-0.4-0.5) and horse manure (0.7-0.25-0.6), yard-debris compost (1-0.2-0.6), cottonseed meal (6-7-2), feather meal (12-0-0), bone meal (2-15-0), and fish emulsion (3-1-1). Avoid using fresh manure products after planting, as this may be a food safety risk.
The main nutrient needed by strawberry plants after planting in all home garden soils is N. Depending on the type of fertilizer product, there are different application methods to ensure maximum availability of N to the plants. Inorganic granular fertilizers are often applied in equal portions, or splits, throughout the spring and summer to ensure maximum efficiency of plant uptake and minimize the risk of salt stress to the strawberry plants. Granular organic fertilizers such as feather, soybean or cottonseed meals require longer periods of time for N to be available. Therefore, it’s best to apply granular organic fertilizers about a month before inorganic fertilizers would be applied.

Liquid inorganic and organic fertilizers are available relatively quickly to plants but may also move out of the root zone quickly. So, for liquid fertilizers, divide the total amount of N into smaller, more frequent applications, such as weekly (see below).
Fertilizer recommendations for N are given in weight of actual N per length of row for the year. The amount of fertilizer to apply depends on the percentage of N in the product. To calculate how much N to apply during the year, divide the amount of N you need by the percentage of N in the fertilizer (Figure 16). For example, if the recommendation is to apply 2 ounces of N and you are using 16-16-16 fertilizer (16% each of N, phosphate, and potash), the calculation would be 2 ounces ÷ 0.16 (the decimal equivalent of 16%), or 12.5 ounces of the fertilizer product. In another example, if you wanted to use soybean meal (6-2-1) you would need about 33 ounces, or 2.1 pounds of product (2 ounces ÷ 0.06).
