Nutritional Requirements
See
Getting Started for soil testing procedures prior to planting. If the soil is prepared properly before planting, only nitrogen is routinely necessary on an annual basis. The soil should be tested every 3 to 4 years after planting to determine the need for other nutrients. Apply no more than 5 pounds of 10-10-10 per 100 linear feet of row in the first year and no more than 10 pounds in subsequent years.
Do not overfertilize. If plants appear to be overly vigorous, reduce the amount of fertilization. Brambles benefit from irrigation, especially during fruit swell, which occurs during the week prior to ripening. Trickle irrigation is preferred for brambles because wetting the fruit with overhead irrigation can increase the incidence of disease. Plants generally require 2 inches of water per week, up to 4 inches during harvest.
