As temperatures begin to rise and the ground firms up, many homeowners look out at their lawn and think the same thing: it’s time to mow.
The grass is starting to grow. The surface feels dry enough to walk on. The mower is waiting in the shed.
That instinct is right. But the first cut of the year is not just another routine mow. It is one of the most influential cuts you will make all season.
Why the First Cut Matters
During winter, grass growth slows dramatically. The plant conserves energy and root development reduces. As soil temperatures begin to increase in early spring, the lawn moves out of this semi-dormant phase and begins rebuilding.
At this stage, the plant is actively producing new leaf growth, but root systems are still catching up. Cutting too much, too soon, can temporarily weaken the plant and slow recovery.
A careful first cut, on the other hand, stimulates lateral growth. Grass thickens through a process known as tillering, where each plant produces side shoots. Light, regular mowing encourages this behaviour. Heavy cutting suppresses it.
Step 1: Check Your Equipment
Before mowing, inspect your mower blades. Blunt blades tear the grass leaf rather than slicing it cleanly. This causes frayed tips that turn brown and increase moisture loss from the plant.
Sharpening your blades ensures a clean cut and a healthier looking lawn almost immediately.
Step 2: Raise the Cutting Height
The biggest mistake in early spring is cutting too short. Avoid removing more than one third of the grass height in a single cut.
In practical terms, if your lawn is 6 cm high, you should not cut it below 4 cm on that first mow. Keeping the lawn slightly higher protects the crown of the plant and allows the root system to strengthen.
Early spring is about trimming and tidying, not scalping.
Step 3: Expect a Change in Appearance
After the first cut, the lawn may look slightly paler. You may also notice small thinning areas that were hidden by longer winter growth.
This is normal. You are revealing the true condition of the lawn after winter. With consistent mowing and feeding, colour and density will improve steadily over the following weeks.
Step 4: Mow Little and Often
In March, mowing frequency depends on growth rate. In mild conditions, cutting every two weeks may be appropriate. In warmer spells, growth can accelerate quickly.
As growth strengthens into April and May, move to weekly mowing. Each cut should remove only a small amount. This consistent light trimming encourages denser turf and reduces stress.
Step 5: Support Growth with Spring Fertiliser
Applying a balanced spring fertiliser provides the nutrients required for healthy leaf and root development. Nitrogen supports green growth, while other nutrients strengthen root structure and improve resilience.
Feeding at this stage supports the recovery process and accelerates thickening.
The Bigger Picture
The first cut of the year is not about achieving a short, striped finish. It is about establishing the right pattern of growth.
A lawn treated carefully in early spring will:
• Develop stronger roots
• Thicken more evenly
• Resist weeds and moss more effectively
• Maintain better colour through summer
In short, it is easier to maintain and more resilient.
Before you do that first cut, take a moment to approach it strategically. A measured start now will pay dividends throughout the entire growing season.
Spring rewards patience.
And lawns remember how you treat them in March.
