5 Lawn care tips for a healthier lawn
Regular scarifying or raking program
The task of scarifying in lawn care is also known as commonly known as dethatching or raking,
all three are basically the same operation. Scarifying is carried out by a powered machine that has
a series of vertical blades or tines mounted on a rotating shaft.
These tines or blades rotate at great speed, and in doing so they slash/cut into the base of the
lawn removing unwanted thatch and moss. This operation should be carried out at least once a year,
preferably twice a year, during the spring and autumn.
If it is only done yearly then autumn is the best time for scarifying, however is moss is a
problem in the springtime, it will need doing again.
The main aim of lawn scarifying is to remove thatch from the lawn. Thatch is the build up of
organic matter, caused by dead leaves, stems, roots of the grass plant. A little thatch is
desirable for the lawn as it helps add wear tolerance and resilience to the lawn.
However when it becomes too excessive it causes problems. These problems include poor rooting,
resulting in weed grasses susceptible to drought conditions, poor drainage and an increase in weeds
The end result is a weak lawn open to a host of lawn care problems.
Like people, lawns require air to breathe and remain in a healthy condition. If aeration is
neglected then it is likely the soil will become compacted, with the air being squeezed from the
soil resulting in poor growing conditions. This results in:
Shallow rooted grasses that suffer in drought conditions.
Poor drainage that encourages disease, moss, weeds etc.
A lack of soil organisms and micro organisms. These organisms (which require air to survive) are
important to the health of the soil as they break down organic matter, thus controlling the thatch
layer in the lawn.
Lawn aeration should be carried out, at least once a year during the autumn. It is often
included in the autumn lawn care renovation program, which also includes scarification, overseeding
and top dressing.
In severe cases of compaction it can also be carried out during the spring time too. Lawn
aeration can be undertaken with either a powered machine or a simple hand fork. The size of your
lawn and your budget will determine which type you choose.
A choice of tines are available for this task, including solid, slit and hollow tines, with each
having their own benefits.
Correct use of fertilizer
It is true that grass requires nutrients to maintain optimum health. However it is important
that it receives the correct amount and the right types of nutrients at certain times of the
There a 3 key nutrients, nitrogen which encourages growth, phosphorous which encourages a strong
root system and potassium which helps harden the plant against disease and other problems.
Nitrogen is applied during the growing season, never during the winter. Phosphorous and
Potassium can be applied at any time, but are especially important during the winter months.
Almost all lawns will have different fertilizer requirements, due to different soil types,
different climates and other influences. What is important is the lawn receives just enough to
maintain healthy and consistent growth.
Too much fertilizer, especially nitrogen can cause unwanted problems with thatch build up and
The correct use of water or irrigation
Another important factor in lawn care is the correct use of water during hot and dry weather
conditions. Too many people rush out with the sprinklers as soon as it turns dry and this can do
more harm than good.
Keeping the lawn constantly soaked restricts soil air and encourages the build up of thatch, due
to the lack of micro organisms. Most lawns will tolerate a certain amount of drought stress and in
fact it will benefit the lawn if the soil is allowed to dry out somewhat.
Therefore water the lawn heavily and then let the soil dry out before applying more water. This
practice encourages deeper rooting. If the lawn is watered every day the soil stays constantly wet,
this creates shallow roots, disease problems and as previously mentioned the build up of
Another tip is to water during the coolest parts of the day, preferably early morning, prior to
the hottest part of the day. Watering during the evening is also OK, but this can increase the risk
of some lawn diseases, therefore morning is the preferred time.
Correct mowing regime
Another overlooked factor is the most common and simple task in lawn care, that of mowing the
lawn. If done correctly it can make a difference to the lawn.
Starting with mower, it is important that the mower is sharp and cutting correctly. If the mower
is blunt then it can tear and damage the grass. Another important aspect of mowing is the cutting
The shorter you mow the lawn the more stress is placed upon it. Although there isn't anything
wrong with mowing your lawn short, be aware that it will require more maintenance to keep it in tip
top conditions. Therefore in most cases it is important to adopt a sensible cutting height that
will reduce the stress to the grass plant.
During the autumn lifting the height of cut on the mower will also help it during the winter
