Grass Cutting Tips

Saturday, June 3, 2023 - Maintaining a well-manicured lawn is a goal for many Winnipeggers. A critical aspect of lawn care is determining the ideal length for your grass. While personal preferences and local climate conditions play a role, several factors must be considered when determining the best grass length for your lawn. This article aims to guide you through finding the optimal length that promotes healthy growth, enhances the appearance of your lawn, and minimizes potential issues.

Different grass species have varying growth habits and recommended cutting heights. Common grass types include Bermuda grass, Kentucky bluegrass, Zoysia grass, and fescue. Research the specific characteristics of your grass type to determine the recommended length range for optimal health and appearance.

Generally, most grass types thrive when kept within a specific length range, often called the "Goldilocks" zone. This range typically falls between 2.5 to 4 inches (6 to 10 cm) in height. Maintaining grass within this range provides several benefits:

  • Enhanced Root Development: Longer grass blades promote deeper root growth, allowing grass to withstand drought and stress better.

  • Weed Suppression: Taller grass shades the soil, preventing weed seeds from germinating and competing with the grass.

  • Disease Prevention: Longer grass helps create an environment that discourages the development of certain diseases, as good airflow and sunlight penetration are maintained.

Grass growth patterns vary throughout the year, so it's essential to adapt your mowing routine accordingly. Spring and Fall allow grass grows slightly longer during these seasons, typically around the upper end of the recommended range. This supports root development and helps the grass better withstand temperature fluctuations.

In summer, as temperatures rise, it is generally recommended to maintain the grass at the lower end of the recommended range. This helps to reduce water loss through evaporation and promotes a healthier, drought-tolerant lawn.

In Manitoba, it's advisable to gradually reduce the grass length before winter sets in. Trimming the grass slightly shorter (around 2 inches or 5 cm) helps prevent matting and allows for more manageable spring growth.

There are a few simple rules to follow that will help you maintain the desired grass length include.

  1. Never remove more than one-third of the grass height in a single mowing session, as it can stress the grass and inhibit its growth.

  2. Dull mower blades tear grass, leading to ragged edges and increased vulnerability to disease. Keep your mower blades sharp for a clean, healthy cut.

  3. Mow the grass when dry to prevent clumping and achieve a more even cut. Wet grass can clog the mower and result in an uneven appearance.

Finding the best grass length for your lawn involves understanding your grass type and seasonal variations and following good mowing practices.

You can achieve a healthy and visually appealing lawn by maintaining the grass within the recommended height range and adapting to the changing seasons.

Regular mowing and proper care will keep your grass thriving, contributing to the overall beauty of your outdoor space.
