The lawn acts as a huge air conditioner that cools your home. It releases lots of oxygen and absorbs tons of dirt and dust to keep you and your family healthy.
1. For cold climate grass, use a 3 cm cutting height the first time to mow dead grass and bring more sun to the top of the herbaceous plants. Raise the blade at least 5 cm during the summer heat. Then lower the blade to 3 cm for the last cup of the year. For hot grass, these heights are approximately 1.5 cm Low.
When adjusting the blade height, measure from a hard surface to the bottom of the cutting deck, then add 1cm. Most of the blades are 1cm above the bottom of the platform.
2. Deep irrigation helps develop deep roots that open up the groundwater supply. Light watering only moistens grass and soil surface, promotes surface root growth, and increases the need for additional watering. Lawns generally require 2-4cm of water per week from you or Mother Nature, applied at three to four-day intervals.
However, this varies considerably depending on the temperature, the type of grass, and the soil conditions. Lawns on sandy soils may need twice as much water as they drain quickly. Lawns in slowly draining clay soils may only need half.
3. The top third of a blade of grass is thin and “leafy,” breaks down quickly when cut, and can provide up to a third of the nitrogen your lawn needs. During decomposition, this light layer of clippings also slows the evaporation of water and prevents weeds from germinating.
But the bottom two-thirds of a blade of grass is hard, “stalked” and decomposes slowly, adding to the straw. If the straw is thick enough, it prevents the sun, air, water, and nutrients from entering the soil. If you cut more than the top third, it will also shake the grassroots and expose the stems that tend to burn in direct sunlight.
4. A well-maintained, sharp, and balanced blade cuts the grass cleanly and evenly. A boring one tears the grass instead of cutting it clean. Damaged grass turns yellow, requires more water and nutrients to recover, and is more susceptible to disease. An unbalanced knife exacerbates the problem and can damage your mower’s bearings. Sharpening and balancing a blade three times a year is usually enough to get a good edge unless it hits a lot of stones. Here we show you how to sharpen a lawnmower knife.
