This 40 lb bag of GroundWork 13-13-13 provides moderate and balanced nutrition. The ratio of equal parts nitrogen, phosphorus, and potassium is helpful for maintaining overall plant health rather than pushing one growth phase. It’s less aggressive than high-nitrogen or high-phosphorus fertilizers, which lowers risk of leaf burn or excessive vegetative growth. Good choice when you want to maintain a healthy garden or landscape. Best applied before or during growing season; watering after application improves nutrient uptake.
