Crop Finisher™

Name: Crop Finisher™ 4-2-41 + 2% Mg
Brand: Crop Finisher™ 4-2-41 + 2% Mg

Boost fruit quality before harvest with Crop Finisher™ 4-2-41 + 2% Mg fertilizer, designed to enhance ripening, sugar accumulation, and crop strength.

Overview

To support ripening and maximize fruit quality, crops need elevated levels of potassium and magnesium during the final stages of development. Crop Finisher™ 4-2-41 + 2% Mg fertilizer delivers these nutrients in a concentrated, highly soluble form along with EDTA-chelated micronutrients. This late-season formulation helps plants channel energy into natural ripening processes, improving color, sugar accumulation, and overall harvest quality.

Compatible with most pesticides, Crop Finisher™ 4-2-41 + 2% Mg fertilizer supports fruit sizing, sugar accumulation, and color development, while complementing soil-applied fertility programs. It is an excellent choice for drip irrigation or foliar application during the final weeks of crop development.

How Does Crop Finisher™ 4-2-41 + 2% Mg Late-Season Fertilizer Work?

Potassium and magnesium are essential during the last few weeks of crop growth, when plants require high energy to complete fruit filling and ripening. Crop Finisher™ 4-2-41 + 2% Mg fertilizer delivers these nutrients in a highly available form to ensure that crops receive the support needed for finishing strong.

By promoting sugar transport, color development, and natural ripening, Crop Finisher™ 4-2-41 + 2% Mg fertilizer helps maximize quality at harvest. The inclusion of chelated micronutrients improves nutrient uptake and balance, while magnesium supports photosynthesis and energy transfer during peak demand.
