Alternatively, apply fertilizers or mulches that are rich in nitrogen to support your grass's healthy growth. Nitrogen is the nutrient responsible for growth and coloring, which makes it vital for grass. In other plants, a large dose of nitrogen can cause rapid, leggy growth. Leaving grass clippings on the lawn recycles the nitrogen, but the process of absorption is too slow for clippings alone to meet all of a lawn's nitrogen needs.
Mulch can help your lawn retain moisture, regulate the soil's temperature and prevent weeds from germinating. If you choose to mulch, a nitrogen-rich mulch has the added benefit of gradually releasing small amounts of nitrogen into the soil. Applying a high rate of nitrogen after the middle of September for the more moderate warm-season areas will increase the shoot and leaf growth while the plant is slowing its growth.
If pushed to grow, the tender new growth is more susceptible to freeze damage. These succulent shoots are prone to being attacked by a common cool-season disease called Large Patch. Another problem with fertilizing later in the fall is that it may increase the number of cool-season weeds that germinate. The three numbers on a bag of fertilizer indicate the percentage by weight of nitrogen, phosphorus and potassium in the bag. The number one nutrient needed by turf is nitrogen.
Here is a chart that provides the amount of nitrogen each turf type needs for the entire growing season. Here are his nine simple-to-follow rules for fertilizing lawns. Or, buy a soil thermometer and check the temperature at any time. In most parts of the country that means the first application of lawn fertilizer should take place by about mid-April.
So, if you haven't started yet, mark that date. When shopping for fertilizer, you'll find three numbers printed on the label. These numbers represent the percentage of nitrogen, phosphate, and potassium, respectively, which are the primary nutrients needed to feed your lawn. So, a bag will have 20 percent nitrogen, 5 percent phosphate, and 10 percent potassium.
The rest of the bag usually contains filler material that helps ensure an even application of the fertilizer. By the way, a lawn fertilizer is a good basic mix to use in spring.
Slow-release lawn fertilizers break down their nutrients over a longer period of time, so you can wait longer between applications. That saves you both time and money.
He recommends a slow-release that contains nitrogen, but not too much. The grass can't get any greener than that. If you use more, you're only going to make the grass grow faster so you have to mow more often," Turnbull explains. So, over four weeks, that's a quarter pound of nitrogen per week, which is way too much," Turnbull says.
When professional landscapers apply fertilizer, they often drive up in a tanker truck and spray your entire lawn in a remarkably short amount of time. But pros do this every day, so they know how to factor in for the wind and make sure the yard gets even coverage. And they have the proper equipment to get the job done right.
The best way to apply Nitrogen to your lawn is by applying a well-balanced lawn fertiliser. Lawn fertilisers are formulated to consider these requirements and will have an appropriate mix of your NPK ingredients macronutrients , micronutrients and trace elements. There are a host of products on the market, all with different attributes and nutrient combinations.
Some turf varieties will need more of some nutrients than others so this can form part of the consideration process. If you are unsure what you need, reach out to your local Lawn Solutions Australia turf supplier who can provide some specific advice for your variety and climate.
But when it rains, the rain forces the nitrogen to the ground. Microorganisms then take over, converting the nitrogen in the soil into ammonia or nitrates that are absorbed by the grass. Not sure whether a liquid or granular lawn fertiliser is needed? We have some more information here.
This Nitrogen is slowly released to your lawn over a few months and is ideal for all lawn varieties.
