Before Vertimowing

What is Vertimowing?

Vertimowing is the process in which thatch is remove from lawn to allow best water absorption and light penetration to the root of a plant. This is done by a specialist mower that has vertical blades that can penetrate the thatch and break it up and lift it out from the grass.

This is also normally followed up by a horizontal mow to shorten the remain stolen and plant leaf to keep it neat tidy and short.

When is the best time to Vertimow?

Ideally is the start of spring to early summer is the peak time due to the availability of light and heat to allow maximum growth of the plant in a shortest possible time. Although we can do it all year round the results and recovery time can be greatly effected.

What is Thatch?

Thatch is the buildup of stolons and dead leaf/organic matter on top of each other over period of time, where the build up is faster than it can break down and gets to a point it is stops breaking down.

What causes Thatch?

There is a few things that cause thatch, it is a natural process however a regular well maintain lawn tends not to suffer the significant problems like those with irregular or poorly maintained lawns.


When a lawn is mowed the mower normally removes 90-95% of the leaf matter from the grass into the catcher, when blades are blunt or worn blade on rotary mowers often struggle to pick up the leaf due to the reduced vacuum the blades are designed to create.  Sometime professional mowers will leave the catcher off to allow small leaf particles to stay on the lawn to act as fertiliser/organic matter.

However when large clumps of leaf and other matter is left on the lawn the lawn gets starved of sunlight, so the lawn grows over the top of this (Stolons) to allow the leaf to get to the sunlight. Then as the clippings break down the disappear into the soil but the stolons are now sitting onto of the previous stolons. This is what causes thatch.

Vertimowing After Process

Why vertimowing benefits your lawn.

By reducing the thatch in a lawn allows better water penetration into the soil and reduces the nutrient requirements of the plant as there is less plant matter that needs feeding.

What is the process of Vertimowing?

As vertimowing is very stressful for the lawn as we are attacking the plant very harshly we need to try and get things in a good way first. As vertimowing will not bring back a dead lawn or a lawn in poor condition, and in some cases can actually kill a lawn if not done correct ie Buffalo Grass.

The first thing we need to do is ensure you have good sprinkler coverage, as part of the recover we need to get the lawn lots of water, we normally recommend applying for a watering exemption and give you details on how to water your lawn and care for it after we have finished.

Second we often need to give it some nutrients into the soil so about a week before we would like to try and apply some fertiliser to the lawn as it normally take 3-4 days for it to be absorbed into the plant.

Then we use the Vertimower to cut the lawn down step by step to the require level, with mowing in between and the removal of the debris left behind. As we get towards the end we use our mower to cut the leaf things up and get a neater finish.

Once we have finished it is basically keeping it watered and reapplying some more fertiliser and monitoring it.

Once we start getting some grown we normally give it a cut again between 2-3 weeks to get the lawn to grow at the recommended height, and the recommend setting up a regular turf maintenance program.

Just be warned the amount of debris from vertimowing can be quite extraordinary and will require a skip bin or some method of disposal, we have a large trailer which we use just for this and even then we sometime require multiple trips and this all adds to the cost of the job. In both time and tipping fees.
