How to change soil ph for lawn grass.
Ph for lawns.
On the other hand sheep fescue and velvet bent grass prefer ph levels between 5 0 and 6 0.
Having the perfect ph level in your soil is important for plants like your lawn to be able to absorb nutrients they need to grow.
Learn why lawn ph levels matter how to test soil ph.
Grasses like a ph between 5 5 and 7.
The ideal ph for most grass types is 6 5 to 7 0.
Turf grass prefers a ph of 6 5 7 0.
Although most turf grasses tolerate ph levels between 5 0 and 7 0 the preferred soil ph level varies with different grasses.
Why your soil ph level matters.
Ph has an effect on plant growth and important nutrients for plants tend to be available in soil when the ph is at those levels.
Note that some grass species such as centipede prefer a more acidic soil with ph levels around 5 0 5 5 considered optimum.
A ph above 8 5 is unusual and also is challenging for plant growth the ph that turfgrasses like.
The soil balance is measured on the 14 point ph scale.
This would be an optimum ph but different grass types can tolerate a range of ph levels see our grass species ph chart below.
An ideal range for bermuda grass zoysia grass and rough blue grass is 6 0 to 7 0.
The low end slightly acidic is preferred by your fine lawn grasses bents and fescues whilst your broader leaved grasses rye and meadow grasses like a more neutral ph at 6 5.
If the lawn ph is too high the plant will have trouble up taking nutrients and certain important microorganisms will be in short supply.
Most plants prefer a soil ph of 6 0 7 0 but a few like things a bit more acidic while some need a lower ph.
Plant and grass nutrients are most readily available around the neutral ph level.
Soil ph is a very important factor in plant health if the soil is too acidic or too alkaline plants will be unable to absorb nutrients and your lawn or garden won t grow.
Lawns with a low or acidic soil ph also tend to grow unwanted plants like weeds or moss.
Like other plants lawn grasses thrive best in soils with the correct balance between acid and alkaline.
