What Does Phosphorus Do To My Lawn?

Phosphorus is an essential nutrient that plays an important role in the growth and development of a healthy lawn. It helps to promote root growth, increase disease resistance and help the lawn to recover from stress. However, like any other nutrient, it’s important to use it correctly to avoid any adverse effects on your lawn.


One of the pros of using phosphorus fertilizer is that it can help to promote root growth. A healthy root system is essential for a strong and resilient lawn. It can also help to increase disease resistance, which can protect your lawn from various fungal and bacterial diseases. Additionally, phosphorus can help your lawn recover from stress, such as drought or foot traffic.

However, there are also some cons to using phosphorus fertilizer. One of the main cons is that if too much phosphorus is applied, it can cause an overgrowth of weeds and unwanted plants. Additionally, too much phosphorus can cause an imbalance in the soil’s pH level and can lead to a decrease in the availability of other nutrients such as iron and zinc.


The best time to use phosphorus fertilizer on your lawn is typically in the spring when the lawn is actively growing. It’s important to follow the instructions on the fertilizer package and apply it at the appropriate time. It’s also important to apply the right amount of phosphorus fertilizer. A general rule of thumb is to apply 500g of phosphorus per 100 square meters of lawn.
