To have a healthy, thick and green lawn it is important to feed it. Just like people, the grass needs to source the right nutrients to grow and survive. Without these essential nutrients, it will be thin and turn a yellow colour. It can also become out-competed by weeds because they can grow more easily than lawns in the low nutrient conditions. Diseases start to take hold, meaning the lawn becomes a lot weaker and has more weeds. Overall, without feeding your lawn, the appearance will deteriorate even more.
What is in lawn feed which makes it so important to feed your lawn?
The nutrients in lawn feed are essential for healthy functioning of the plant. The three main nutrients which are in lawn feed are as follows:
- Nitrogen: this is an essential building block of protein. Without nitrogen the lawn doesn’t have the resources to grow well, and will turn yellow as the number of photosynthesising structures reduce
- Potassium: this helps the lawn to be more damage resistant from various conditions such as frosts and wear and tear
- Phosphorus: this helps to build a strong root structure.
But, where do the nutrients in the soil go?
The nutrients in the soil will gradually be released to the grass plants as the soil weathers. However, a large number of the nutrients in the soil can be lost. Some of the nutrients can be locked away in forms that are unavailable to plants. Some of the nutrients such as nitrogen compounds are very soluble and tend to get washed out of the soil by rainfall, meaning these nutrients are completely lost. The biggest source of loss of nutrients in lawns is through mowing. As the grass grows, it takes up the nutrients, but when we mow the lawn, we chop off a large amount of the leaves and take away the nutrients. Nutrients can be lost from the soil in many different ways, and this is why we need to feed the lawns to replenish them.
What lawn feed do I use and how often do I apply it?
When deciding which Aftercut lawn feed to use, it is important to look at the NPK
Aftercut All In One contains a large amount of nitrogen with NPK 10-2-2 as well as weed killer and moss killer, for a lovely green lawn. However, this can only be used twice a year. It also needs to be watered in within 48 hours due to the high amount of nitrogen.
However, Aftercut Ultra Green + has a lot less nitrogen in it with NPK 4-1-4. This means it can be applied every 3-4 weeks from February to September which gives a steady supply of nutrients for the lawn.
Aftercut Lawn Thickener can also be considered, as this product contains fertiliser and seed. It’s NPK is 3-1-3. Just one application every 3 to 4 weeks during the season feeds and thickens your lawn.
