Why Controlled-Release?

Traditional fertilizers release nutrients quickly, often faster than plants can use them. This leads to nutrient loss through leaching, requiring multiple applications throughout the season. GrapeMax's 75% controlled-release nitrogen is coated to release gradually based on soil temperature and moisture, matching plant uptake patterns. This means more efficient nutrition, fewer applications, and better environmental stewardship.

Application Guidelines

Grapes: Apply 200-400 lbs per acre in early spring before bud break
Berries: Apply 150-300 lbs per acre at the start of the growing season
Tree Fruits: Apply 1-2 lbs per inch of trunk diameter around the drip line
Timing: Single application in early spring provides season-long nutrition

Application Tips

  • Apply in early spring as plants begin active growth
  • Broadcast evenly around the root zone or drip line
  • Water in thoroughly after application to activate controlled-release coating
  • Avoid applying before heavy rain to prevent runoff
  • Store in a cool, dry place in original packaging

Why Choose GrapeMax?

Developed specifically for grape and fruit crop production, GrapeMax delivers the high potassium levels fruit crops need for quality production, combined with controlled-release nitrogen for efficient, season-long feeding. The result is better fruit quality, reduced labor, and improved environmental performance compared to conventional fertilizers.
