Avoid patches in your lawn

Have you noticed brown patches appearing on your lawn after mowing? This is a result of accidental scalping.

Let’s look at why this occurs and how to avoid scalping your lawn when mowing.

Determine Why Your Lawn is Scalping

The first step is to determine why scalping is occurring. Scalping occurs when a lawn is mown too short. When too much of the leaf is removed at once, it will cause areas of the grass to look brown.

Here are some reasons why scalping might be occurring on your lawn.

1. Has the lawn been growing too long in between mows?
2. Are your lawns levels uneven? Are there high and low sections of the lawn?
3. Does your lawn have an accumulation of thatch?

How to Reset the Height of Your Lawn TO AVOID A PATCHY LAWN

If scalping occurs from your lawn growing too long in between mows or an accumulation of thatch it is best to reset the height if your grass.

REDUCE YOUR LAWN HEIGHT

To do this, give the lawn a low mow a notch or two below your normal/preferred mowing height. If your lawn has an accumulation of thatch, you may need to bring down the mower a few more notches to allow it to reach down into the thatch layer. (When lowering the mowing height on Buffalo it is best to ensure you are not mowing too low and cutting into the runner).

After you mow the lawn, it won’t look great at first, but it will be able to recover over the coming weeks. During this recovery period, it is best to ensure you keep water up to the lawn. Raise your mower back up to your preferred mowing height on your next mow. This process is best done while the lawn is actively growing throughout the warmer months and should be avoided in the cooler months while your lawn is growing at a slower rate.

MOW FREQUENTLY

After this, you will need to ensure you are frequently mowing to help avoid scalping the lawn again.

As a rule of thumb, mow your lawn frequently enough so that only one-third of the leaf is removed with each pass. This means you will need to mow more frequently in warmer months as the grass grows faster. Conversely, you won’t need to cut as often in the cooler months as the grass will grow slower.

How to Fix Your Lawns Levels To AVOID A PATCHY LAWN

If scalping occurs from mowing over high spots in your lawn, you can add soil/sand to amend the lawn levels. This process is known as top dressing. When top dressing to improve levels, we recommend using sand, such as washed river sand.

When top dressing, it is best to give the lawn a low mow beforehand to ensure the top-dressing material will reach the soil profile. It’s also best to also ensure at most 5-10 mm thickness is applied at one time. always ensure that the lawn blades are poking out so the lawn is still exposed to sunlight and other vital nutrients.

The sand should be rubbed in evenly using a lawn-leveller bar or the back of a rake to work the sand into the profile.

You can also fertilise the area prior to top dressing. The recommendation is to fertilise the lawn a week to two before applying a top dressing regardless of whether this is for nutrients or to repair holes or an uneven lawn. This boost to the lawn plant’s growth will assist the turf to push through the dressing more easily and quickly. We recommend Lawn Solutions Premium Fertiliser.
