Spring Summer 20-10-10 Blend Fertiliser 20kg

GT Spring Summer 20-10-10 Blend Fertiliser 20kg is a professional-grade granular fertiliser developed to promote rapid lawn greening, vigorous grass growth, and improved turf strength during the active spring and summer months.

Formulated with a balanced 20-10-10 NPK ratio, this high-nitrogen fertiliser delivers the essential nutrients lawns need for healthy leaf growth, strong root development, and improved resilience against wear, drought, and seasonal stress. The nitrogen content stimulates rapid green-up and dense turf coverage, while phosphate supports root establishment and potassium strengthens plant health and turf durability.

Ideal for use on domestic lawns, landscaped gardens, parks, sports fields, commercial green spaces, and paddocks, this versatile fertiliser provides consistent nutrition and reliable results throughout the growing season. The granular formulation ensures even distribution and controlled nutrient release, helping maintain lush, healthy grass across large areas.

Supplied in a 20kg professional bag, this fertiliser provides excellent coverage and is suitable for both homeowners and landscaping professionals looking to revitalise tired lawns or maintain high-quality turf through the warmer months.
