There are a few things to consider before laying a new lawn. Area preparation is the most important step in ensuring your lawn will look its absolute best!
Where to start?
Successful establishment of all lawn varieties relies on proper soil preparation.
By following this list of tips and tricks for preparing the soil, you will encourage a happy and healthy lawn.
NOTE: Preparation for establishing a lawn usually begins after construction activities have finished, or before topsoil has been introduced.
1. ASSESS Your Soil
Without preparing your soil properly, your lawn can suffer from poor soil drainage, compaction, pH or fertility problems that could have otherwise been simply prevented.
- Keep drainage and the grade of your lawn area in mind as it should slope enough to allow surface water to drain away from your house, yet be gradual enough to allow for easy maintenance and outdoor activities.
- Where steep slopes exist (over 40%) or grades change drastically, consider installing retaining walls or other surface plantings in these areas as mowing and other maintenance may become difficult after you’ve finished.
- Consider installing an irrigation system.
2. CLear your soil
- Removing weeds and debris is important when preparing your soil. One of the best methods for eliminating weeds is using an environmentally-friendly herbicide, such as a non-residual glyphosate herbicide like Roundup. This should be followed by their removal.
- A second dose of ‘Roundup’ may be required as a soil turnover can ‘wake-up’ any dormant or hidden weeds lurking deep within your soil. This ensures complete eradication of any existing weeds and reducing the chance of them appearing in your new lawn.
- Allow 2 weeks after the application of ‘Roundup’ before proceeding with topsoil.
- Once all lawn and weeds have been removed rotary hoe your soil. It is recommended to strip the top layer of your soil by roughly 150mm. This will also ensure the removal of any debris, clay or poor growing medium.
- If you find your existing soil is compacted with heavy clay soils, it is recommended to applied Gypsum. Gypsum has been used to reduce soil compaction, improve soil structure, increase air movement, and prevent reduce water run-off.
3. Test you SOil
- Test and adjust soil pH levels. The ideal pH range for your lawn is somewhere between 6.5 and 7.4.
4. Prepare your TOPSOIL
- A topsoil mix of 80% sand to 20% soil of 150mm in depth is advised for most turf varieties (Sir Walter Buffalo, TifTuf Bermuda & Eureka Kikuyu). * This free draining environment creates an ideal growth space for the root system, encouraging nutrients to freely flow deep into the soil.
2. Your soil should sit approximately 35mm lower than your paths, driveways, etc. This will allow for the turf to sit flush with your paths or paving. Once the topsoil is levelled, you are almost ready to lay your new turf
5. THE final touches- Time for turf!
- From here we recommend using a starter fertiliser called Lawn Launcher. This is a mix between granular slow-release fertiliser and water crystals, or moisture magnets that assist with establishment and water retention. When wet, they will swell dramatically to become super absorbent. The collected water is then released to your lawn when it needs it. This product should be applied to your topsoil prior to laying new turf
- You’re all set. All that’s left to do is laying your new lawn.
