Cultivation and Care
Zoysia grass requires specific care practices to thrive in your lawn. Proper planting, watering, feeding, and mowing techniques are essential for maintaining a healthy and attractive zoysia turf.
Planting Guidelines
To establish a zoysia lawn, you have two options: seeding or planting plugs. Seeding is best done in spring or summer when soil temperatures are warm. Spread the seeds evenly and lightly rake them into the soil. Water thoroughly after seeding.
For plugs, space them 15-30 cm apart in well-prepared soil. Ensure good soil contact and water regularly until established. Zoysia prefers full sun but can tolerate partial shade.
Choose a site with well-draining soil and a pH between 6.0 and 7.0 for optimal growth. Prepare the area by removing weeds and debris before planting.
Watering and Feeding
Zoysia grass is known for its drought tolerance, but proper watering is still crucial for a healthy lawn. Water deeply but infrequently, allowing the soil to dry between waterings. This encourages deep root growth.
During establishment, water more frequently to keep the soil consistently moist. Once established, zoysia typically needs about 2.5 cm of water per week, including rainfall.
Fertilise your zoysia lawn every 6-8 weeks during the growing season. Use a low-nitrogen fertiliser to promote steady growth without excessive thatch build-up. Apply fertiliser when the grass is actively growing, usually from spring to early autumn.
Mowing and Thatch Control
Maintain your zoysia grass at a height of 2.5-5 cm. Mow regularly during the growing season, removing no more than one-third of the blade length at a time. This promotes a dense, attractive turf.
Begin mowing in spring when the grass turns green, typically a week or two after the last frost. Adjust your mowing frequency based on growth rate, which may increase during warmer months.
Zoysia can develop thatch, a layer of dead grass between the soil and living blades. To prevent excessive thatch build-up:
- Avoid over-fertilising
- Mow regularly
- Water deeply but infrequently
- Dethatch if the layer exceeds 1.3 cm
Regular maintenance helps keep your zoysia lawn healthy and attractive throughout the growing season.
Seasonal Considerations
Zoysia grass requires different care throughout the year to maintain its health and appearance. Adapting your lawn maintenance routine to the changing seasons is crucial for a thriving zoysia lawn.
Summer Care
During summer, your zoysia grass thrives in the warm weather. Mow your lawn to a height of 1 to 2 inches to promote lateral growth and prevent thatch buildup. Water deeply but infrequently, allowing the soil to dry between waterings. This encourages deep root growth and drought tolerance.
Apply a nitrogen-rich fertiliser every 6-8 weeks to support healthy growth. Be mindful of pests like grubs, which can damage your lawn. Use targeted treatments if you notice any signs of infestation.
Keep an eye out for weeds and remove them promptly. Consider using a pre-emergent herbicide at the start of the growing season to prevent weed establishment.
Winter Dormancy
As temperatures drop, your zoysia grass will enter dormancy and turn brown. This is a natural process, so don’t be alarmed. Reduce mowing frequency and raise the cutting height slightly to protect the grass from cold damage.
Limit watering during winter, as the grass requires less moisture when dormant. Avoid walking on frosted grass to prevent damage to the blades.
Before winter sets in, consider aerating and dethatching your lawn if necessary. This helps improve soil health and prepares the grass for the upcoming growing season.
Perform a soil test every few years to check nutrient levels and pH. Aim for a slightly acidic soil pH of 6.0-6.5 for optimal zoysia growth.
Common Challenges
Zoysia grass faces several hurdles that can impact its health and appearance. These issues require attention and proper management to maintain a lush, thriving lawn.
Shade Tolerance
While zoysia is known for its shade tolerance, it still needs a fair amount of sunlight to thrive. You might notice your zoysia struggling in heavily shaded areas.
To combat this:
- Trim overhanging branches to allow more light
- Consider planting shade-tolerant varieties like Sir Grange
- Reduce traffic in shaded areas to minimise stress
If shade persists, you may need to overseed with more shade-tolerant grass species or create mulched areas under trees.
Soil Compaction
Zoysia grass can suffer when soil becomes too compacted. This restricts root growth and water penetration.
To address soil compaction:
- Aerate your lawn annually, preferably in spring
- Reduce foot traffic, especially when the soil is wet
- Add organic matter to improve soil structure
Consider using a core aerator for best results. This removes small plugs of soil, allowing air, water, and nutrients to penetrate deeper.
Invasive Nature
Zoysia’s vigorous growth can be a double-edged sword. While it creates a dense, weed-resistant turf, it can also invade other areas of your garden.
To manage its spread:
