Ultimately, the choice between liquid and granular fertilizers depends on your specific needs and preferences.
Application and Timing
To apply high nitrogen fertilizers effectively, it's crucial to accurately measure the area of your lawn. This ensures you don't over or under-apply the fertilizer, which can lead to nutrient imbalance or lack of growth.
Timing matters, as high nitrogen fertilizers should be applied during periods when plants are actively growing, typically during spring or early summer seasons. This leads to maximum use of nutrients by the grass.
Water should be applied generously on the grass after application to help the fertilizer sink into the soil and start functioning effectively. Avoid applying fertilizers immediately before a heavy downpour so that there is no leaching away (run off) and loss.
The most effective time for adding nitrogen fertilizers to lawns is when they are actively growing, which corresponds to spring and early summer months. Soil temperatures between 55°F-65°F are ideal for nitrogen uptake.
