They come from giving the right nutrients at the right time. Before you start with fertilizing your lawn, you need to always do a quick soil test and create a plan that matches your grass type and the current season.

Understanding Lawn Fertilization: The Basics Get comfortable with the basics so that your grass gets what it needs. There are some basics you need to know about lawn fertilization before you get started. Fertilizing a lawn is all about feeding the turf with the right blend of nutrients necessary for optimal growth. It’s also important that you know about NPK fertilizer. This refers to nitrogen (N), phosphorus (P), and potassium (K), which are the big three that play different roles in ensuring that you have a healthy turf. A number of factors influence the nutrient needs of your lawn. The grass type is one. Cool and warm season grasses usually have different nutritional needs. Also, the soil type matters. Sandy soils usually require more frequent applications of fertilizer as compared to clay soil. The climate also has a big role to play in determining the nutrient needs of your lawn.

How to Determine Your Lawn’s Nutritional Needs You need to know exactly what nutrients your grass needs before you go ahead and choose a fertilizer. Start by taking a portion of your soil and sending it for a lab test which will show what nutrients are present and what nutrients are missing. You can also make use of a pH test on your lawn to check if there’s any acidity that is currently limiting nutrient availability.

Best Time to Fertilize Your Lawn: Seasonal Insights Over time, it has been discovered that cool season lawns tend to respond best to late summer into fall feeding, which is why creating an appropriate schedule for your fertilization during fall is a lot more important than any single spring pass. You can fertilize your lawn during spring sparingly for green-up and then allow the cooler weather to carry deeper rooting. Keep in mind that the local climate and rain patterns actually decide when you should fertilize your lawn. Avoid any applications before a downpour and water-in just after light showers. As previously mentioned, cool season and warm season grasses usually have different requirements. For example, warm season grasses tend to prefer nutrients in late spring and throughout summer warmth.

Once you are done, get your hose, turn it on, and then water your lawn so that the granules are able to dissolve into the soil rather than just sitting on top of it. Common Mistakes to Avoid When Fertilizing There are a number of mistakes you should try your best to avoid when fertilizing your lawn. The first one is feeding ahead of a downpour which risks runoff, wasted money, and a stressed yard. It’s best to hold off on drought-tired turf since salt can linger on blades and lead to burning of the grass when fertilizer is applied. A number of signs usually show up when you over-fertilize your lawn. These include streaks, yellowing, and brittle leaf tips. After you have performed a soil test, build a plan around it, and then use the product label for rates, spreader settings, and watering instructions so that your fertilizer application remains as safe as possible for your lawn. Post-Fertilization Care: What to Do Next Your job does not end the moment you finish applying the fertilizer. Grass that has just been fed usually likes gentle moisture, because it helps to activate nutrients without causing runoff. So it’s important that you plan your watering schedule properly after fertilizing. A little water after feeding helps your lawn soak in the goodness Another way you can maintain your lawn health after fertilizing is by keeping feet, pets, and equipment off the yard until the granules are able to settle. This will help prevent stripes and hot spots from forming. You should hold off on mowing so that the application can absorb cleanly. Also, save core work for later because fertilization usually works best when aeration is done beforehand. Finish up your lawn care after fertilizing by mulch-mowing, as clippings help to return nutrients back to the soil. Lawn Fertilization Myths Debunked There are a number of myths about lawn fertilization, and it’s important that we set the records straight and clarify them. First, more fertilizer does not always mean better results. In fact, excess granules can scorch your turf and then wash into drains after the rain. Another common lawn misconception is that any fertilizer can work on any grass. This is also not true, as different grasses usually have different needs. And if you’re wondering if organic fertilizer is always better and can’t harm the environment, then that isn’t true, because over-application of these fertilizers can still pollute water with nitrogen and phosphorus.

The pros of organic fertilizers are usually seen in better soil life and crumbly structure. However, these results tend to appear gradually. To care for your lawn in the most eco-friendly way possible, match the nutrients to the results from a soil test. Make use of synthetics to quickly correct any visible deficiencies and rely on slow-release lawn food to maintain even feeding all through the season.
