Optimal Grass Length: Finding the Ideal Grass Height for Mowing

18 Jul Optimal Grass Length: Finding the Ideal Grass Height for Mowing

Achieving the perfect lawn requires more than just watering and fertilisation; Mowing your grass is a crucial way of keeping your lawn looking fresh, luscious and healthy.

Although all grasses should be cut regularly in order to keep them healthy, the ideal height for your grass depends on a number of factors. These factors include what type of grass you have and what season it is. In this guide, we’ll explore different kinds of grass and their optimal cutting lengths.

Why Cutting Length Matters For Your Grass

Like all plants, different types of grass have different needs. Keeping your grass at its optimal height is important for several reasons. Not only does it help keep your lawn looking fresh and healthy, it also has a number of other benefits, such as helping the roots develop. Furthermore, your grass’ optimal height helps improve drought resistance, manage the growth of weeds, and helps prevent disease.

Grass Types and Their Different Optimal Lengths

Grasses are generally catergorised into two main types: cool season and warm season grasses. Warm-season grasses prefer warmer climates, which means they grow best during the summer months. Cool season grassess, on the other hand, grow best during spring and autumn. Here is a short overview of the different kinds and their optimal length:

Warm Season Grasses

• Kikuyu Grass: The optimal height for Kikuyu Grass is between 25mm and 40mm.
• Matilda Buffalo: Matilda Buffalo Grass is best cut between 35mm to 45mm in full sun. However, if it’s in the shade, cut anywhere between 50mm to 60mm.
• Santa Ana Couch Grass: The optimal height for Santa Ana Couch Grass mowing is anywhere between height 8mm to 15mm.

Cool Season Grasses

• Fescue: If you have Tall Fescue Grass on your lawn, try to cut at a height of 40mm. This will keep this grass looking fresh and at it’s healthiest.
• Bentgrass: Bentgrass requires consistent mowing to maintain their desired height. Cut by 15mm to 25mm each time to keep it looking fresh.

Common Mistakes to Avoid when Mowing Your Grass

• Cutting too short: scalping your lawn weakens the grass and makes it more susceptible to weeds, disease and drought.
• Irregular Mowing: Each type of grass has their own needs. Ignoring the optimal mowing height of your grass can be harmful in the long run. Letting your grass grow above the optimal height can increase the chance of unwanted scalping.

By understanding the different types of grass and their optimal lengths, you can ensure that your lawn will be looking perfect all year round. For more information, contact us at Australian Seed and Turf for expert advice on all your lawn and turf questions!
