A healthy lawn can withstand numerous environmental pressures that grass plants encounter on a regular basis, such as drought, insects, diseases and weeds. Proper and consistent maintenance practices such as watering and mowing help maintain the basic foundation for a healthy lawn. An even more important lawn care practice is satisfying your lawn’s hunger. Delivering the right nutrients, in the right amounts, at the right time helps homeowners achieve a lush, thick, healthy lawn. Lawns need numerous elements to grow strong and healthy. Each nutrient has a purpose and is required in different amounts. If there is a deficiency of any one element, the grass plants’ growth can become limited. Fortunately, many elements are supplied to the plants as a result of natural processes occurring in the soil. There are three primary nutrients in a lawn fertilizer, which are nitrogen, phosphorus and potassium. Nitrogen promotes growth, and the desirable green colour that we all want for our lawns. Too much or too little nitrogen can cause problems that can be difficult to fix. Too little nitrogen can cause your lawn to grow slowly, become yellow in colour, and become more susceptible to lawn diseases, insects and weeds. Too much nitrogen can lead to excessive top growth, reduced root growth, and creates a poor tolerance to environmental pressures which can lead to disease issues. Phosphorus is important in stimulating early root growth and promoting early health and strength in plants. Phosphorus moves very little in the soil, but it can move out of the soil via surface water that leads to erosion. Phosphorus run-off has been linked to the degradation of fresh bodies of water. Thankfully, most soils are naturally high in phosphorus, and are able to supply enough to grass plants to enable vigorous growth for many years, without having to supplement naturally occurring phosphorus via inclusion in lawn fertilizer. For this reason, Weed Man’s primary fertilizer blends are phosphorus-free. Potassium plays an important role in the synthesis of some plant components, and plant health. It helps plants absorb and use the other elements more efficiently, such as nitrogen. A deficiency in potassium lowers your lawn’s tolerance against a myriad of environmental pressures and stresses, which can lead to turf diseases. Fertilizers are available with one, or a blend, of the above primary nutrients. On every bag of fertilizer you will notice three bold numbers on the label. These numbers represent the quantities of nitrogen, phosphorus and potassium. Your lawn’s required maintenance and treatments depend on several factors, including where you live, the amount of sun exposure, the condition of your lawn, etc. Take advantage of a free healthy lawn analysis from your local Weed Man professional.
