Can I Fertilize My Lawn Every 2 Weeks?
No, fertilizing every 2 weeks is too frequent for most products and can cause fertilizer burn, excessive growth, thatch buildup, and environmental pollution from nutrient runoff. Most lawn fertilizers are designed for 6-8 week intervals. The exception is Milorganite (organic, cannot burn) which some enthusiasts apply monthly. Liquid fertilizers at half-rate can be applied every 2-3 weeks safely.
