Blueberries are sensitive to excess levels of fertilizer. Do not go over the recommended amount.

Year of Planting: Apply fertilizer according to soil test and work into the soil before planting.  Every six weeks thereafter apply a high nitrogen fertilizer such as a 27-3-3, 29-5-4, 30-3-3 or something similar. Though recommended for lawns, these fertilizers will also work well for blueberries as long as they do not contain weed killers or crabgrass preventers. Apply 1 teaspoon per plant within a circle within

12 inches of the plant. Do not apply fertilizer past August 15. Urea

(46-0-0) may be substituted for the fertilizer recommended above but cut the amount to a rounded ½ teaspoon per plant.

Second Year: Double the rates recommended above and increase the area treated to within 18 inches of the plant. Apply the first application when the new growth appears in the spring and continue every six weeks but not after August 15.

Third Year and Following:

– Apply 1/3 cup of the fertilizer recommended above within three feet of each plant when growth begins in the spring. Bushes should produce 6 to

12 inches of new growth each year. If less than this is produced or if you wish larger plants, apply 1/4 cup of fertilizer every 6 weeks. Do not apply fertilizer after August 15. (Ward Upham)
