Spring Lawn Mowing Guide: Perfect Cutting Height Tips

Spring is here, and for anyone passionate about a healthy, green lawn, that means it’s time to start thinking about lawn mowing. After months of winter dormancy, your lawn is waking up, and getting the cutting height right now can make all the difference. In this guide, I’ll share expert tips from over a decade of experience in New Zealand’s lawn care industry, including practical advice that homeowners can implement immediately.

Whether you’re a busy professional, a new homeowner, or someone who enjoys getting hands-on with their garden, these tips will help you achieve a lush, well-manicured lawn this spring.
 

Why Spring Lawn Mowing Matters in Central Auckland

Spring lawn mowing is more than just keeping your grass at a neat height. It sets the stage for healthy growth throughout the season. After winter, grass can become patchy or uneven, and mowing correctly can:

• Encourage stronger root development
   
• Improve air circulation to the soil
   
• Reduce pests and diseases
   

From my experience, lawns that get proper spring care often require less maintenance later in the year. I remember one client in Auckland whose lawn looked tired and patchy in early September. After adjusting the cutting height and regular mowing every 7–10 days, by November, it was thick, green, and almost weed-free.
 

Understanding the Right Cutting Height

One of the most common mistakes I see homeowners make is mowing too short. It’s tempting to cut the grass low for a neat look, but in spring, keeping it slightly longer protects your lawn from stress.

Recommended cutting heights for New Zealand lawns:
 

• Buffalo grass: 50–60mm
   
• Kikuyu: 30–50mm
   
• Fescue or Ryegrass: 25–40mm

Why this matters: Longer blades capture more sunlight for photosynthesis, helping the grass recover quickly from winter. In my experience, raising your mower by even 10mm can dramatically reduce browning and stress.
 

Choosing the Right Mowing Frequency

Mowing frequency depends on your grass type, soil conditions, and how quickly your lawn grows in spring. For most lawns in New Zealand:
 

• Once a week: Ideal for busy homeowners and those with slow-growing lawns
   
• Every 5–7 days: Perfect for lawns growing rapidly after rainfall
   
• Avoid cutting more than 1/3 of the blade: This prevents shock and promotes healthy growth

I often tell clients: it’s better to mow more frequently at a slightly higher setting than to let the grass grow long and then cut it too short in one go. The lawn recovers faster, and you’ll notice a more even, greener appearance.
 

Mower Maintenance for Optimal Cuts

Even the best techniques can fail if your mower isn’t in top condition. Dull blades tear grass instead of cutting it cleanly, which can lead to brown tips and disease.

Tips from the field:
 

• Sharpen mower blades at least once a season
   
• Check tire pressure for even cutting
   
• Clean the deck to avoid clumps of grass that block airflow

I remember servicing a client in Wellington whose mower was cutting unevenly. After sharpening the blades and raising the height slightly, the lawn looked smoother in just two weeks.
 

Practical Cutting Techniques
 

Getting the right height is just part of the process. How you mow also matters:
 

1. Alternate your mowing pattern: Changing direction prevents soil compaction and encourages upright growth.
    
2. Mow when the grass is dry: Wet grass clumps and can damage the mower deck.
    
3. Edge carefully: Use trimmers or edging tools to maintain neat borders without cutting too deeply.

By combining the right height with proper technique, your lawn will look consistent, healthy, and professional—even without hiring a landscaper.
 

Seasonal Adjustments for Spring Lawn Health
 

Spring is a transition period for lawns. Aside from mowing, consider these adjustments:
 

• Fertilize lightly: A balanced spring fertilizer gives the lawn nutrients it needs for strong growth.
   
• Aerate compacted areas: Spring rains can compact soil; aeration improves water and nutrient absorption.
   
• Monitor for weeds: Early spotting of weeds makes removal easier and prevents them from taking over.
   

A local example: In Hamilton, a client’s Kikuyu lawn was thin and patchy in early spring. After proper mowing, fertilizing, and a light aeration, the lawn doubled in density within six weeks.

 

Common Lawn Mowing Mistakes to Avoid
 

Even experienced homeowners can make mistakes. Here’s what to watch for:
 

• Cutting too short: Weakens the lawn and exposes soil
   
• Mowing wet grass: Leads to uneven cuts and disease
   
• Ignoring mower maintenance: Dull blades create torn, brown tips
   
• Skipping mowing during growth spurts: Grass can get too long and stress when cut short
   

Sticking to these guidelines ensures your lawn remains healthy, dense, and green throughout spring and summer.

FAQs

1. How to mow your lawn in spring?
In spring, mow your lawn when the grass is dry and has grown about 3–4 inches tall. Set your mower to a higher setting and trim only the top one-third of the grass. This helps promote strong roots and keeps your lawn healthy.

 

2. What is the ideal height for spring lawn mowing?
The 1/3 rule means you should never cut more than one-third of the grass blade’s height at a time.Cutting too much stresses the grass and weakens the lawn.

 

3. What length should I mow my lawn in spring?
In spring, keep your lawn about 2.5 to 3.5 inches tall. Mowing at this height encourages deeper roots, helps retain moisture, and keeps weeds from taking over.

4 Is it bad to cut grass too early in spring?
Yes, mowing too early can stress the grass. Wait until it’s grown to about 3–4 inches and the soil is firm. Cutting too soon may damage new growth and weaken the lawn.
