How to Choose Lawn Seed
Find the grass type that grows best in your location and climate. Grasses fall into two general categories: cool season and warm season. Warm season grasses are summer hardy, very wear resistant, tougher, are more able to be mowed lower and include couch grass and kikuyu grass. Cool season grasses are comfortable underfoot and often have a brilliant green colour. If watered during warm seasons they’ll maintain this colour all year round. These include ryegrasses, fescues, bluegrasses and bentgrasses.
Pure Live Seed Tip
SEED TIP: Pure Live Seed (PLS) is a measure used by the seed industry to describe the percentage of a quantity of seed that will germinate. To calculate the PLS, the percentage of pure seed listed on the seed certificate is multiplied by the percentage germination, and then divided by 100. e.g. 98% seed purity x 90% seed germination/100 = 88.2%. To work out how much seed to plant, divide 100 by the percentage PLS. e.g. 100/88.2 = 1.13.
Thus 1.13kgs of seed with a purity of 98% and germination of 90% would be needed for each kg specified. This is a good way to determine if what you’re purchasing is a good buy.
What is a Sowing Rate?
‘Sowing Rate’ is the total amount of seed you need to effectively cover the area of lawn that you’re creating. This basically tells you how much grass seed per m2 you need. Different lawn seeds have slightly different sowing rates.
For new lawns, couch seed has roughly a 1kg per 100 square metre sowing rate while finer varieties like fescues have a higher rate, around 4 or 5kg per 100 square metre.
Lawns that are constantly growing and being mowed are prone to losing nutrients. A simple and quick fertilise will replenish what a lawn needs to survive and thrive and should be part of regular lawn maintenance. A complete fertiliser contains all three of the major nutrient elements nitrogen (N), phosphorus (P), and potassium (K). Nitrogen helps to produce the green leaves in the plant, phosphorus and potassium give the lawn good root development, strength and disease resistance.
Bentgrass Conversion and How It Can Work
Bentgrass conversion can refer to changing from one bentgrass cultivar to another, or converting from Poa annua or perennial ryegrass to bentgrass. All of these can be done on greens, tees and fairways but the success rate depends on many factors. These factors include the climate zone of the course, the acceptable amount of disruption of the playing surface, timing of conversion and amount of perseverance.

Classifications of Bentgrass Cultivars
When looking to overseed, renovate or for new sports turf constructions, there are more choices with regards to new creeping bentgrasses coming onto the market. These new cultivars are the result of many years of work to improve the performance of creeping bentgrass. With improved characteristics including disease resistance, higher density at low mowing heights, i higher stress tolerance and more. Click here to view the Article from SRO Seed.
Fine Fescue Low Maintenance Grass
In the United States, the use of lower maintenance turfgrasses is increasing. There are lots of reasons for this trend. Ranging from restrictions on water use, lower budgets, environmental concerns, and pesticide regulations. Take a look at the reasons to consider using low maintenance grasses.
