Description
Stark® Blueberry Special Fertilizer is formulated specifically for blueberries, which have more demanding and specific nutritional requirements than most fruiting plants. Standard balanced fertilizers miss two things that blueberries need: acid-forming nitrogen to support their preference for acidic soil, and sulfur and magnesium to maintain the pH range and fruit quality that blueberries require. The 12-12-12 formula with added sulfur and magnesium addresses all of it, supporting strong root systems, healthy foliage, and high fruit yields from plants that will reward the right nutrition for decades. A Stark Bro’s exclusive.
Why Blueberries Need a Specialized Fertilizer
Blueberries are acid-loving plants that thrive in soil with a pH of 4.2-5.0 — significantly more acidic than most garden plants prefer. Standard fertilizers formulated for a broad pH range can actually work against blueberry health by pushing soil pH in the wrong direction. Blueberry Special’s acid-forming formula supports the acidic soil conditions that allow blueberries to absorb nutrients effectively, while the added sulfur helps maintain that pH over time and the magnesium supports the chlorophyll production that drives healthy, productive growth.
Application Rates by Plant Age
Blueberries are sensitive to over-fertilization — always apply at the correct rate for the plant’s age and water thoroughly between applications.
First-Year Plants: Begin fertilizing after leaves reach full size. Apply 1 tablespoon in a 1-foot circle around the plant. Repeat every 6 weeks until midsummer.
Second-Year Plants: Increase to 2 tablespoons in a circle 1.5 feet from the plant. Apply when new growth begins in spring.
Mature, Bearing Plants: Apply 1 cup when new growth appears in early spring.
Check soil pH regularly and mulch plants to improve moisture retention and root health. Always water thoroughly between applications.
