Zoysia Lawn Care: How to Look After Empire Zoysia & Zoysia tenuifolia Year-Round
Zoysia lawns are low-growing, dense and slow to spread, which makes them excellent for low-maintenance, premium-looking turf. Good zoysia grass care focuses on the basics: the right mowing height, deep but infrequent watering, light but consistent feeding, and a simple zoysia care calendar that protects colour and density through winter. Empire zoysia prefers full sun with occasional shade, while Zoysia tenuifolia suits decorative, mounded areas that are not heavily trafficked.
This guide covers caring for zoysia grass, including Empire zoysia lawn care, zoysia tenuifolia care, mowing, watering, soil preparation and zoysia winter care, so you can keep your lawn thick, soft and weed-resistant all year.

Zoysia Lawn Basics: Growth Habit, Texture & Traffic Tolerance
Zoysia is a warm-season turf grass known for its dense mat, fine-to-medium leaf and naturally low growth habit. Compared with more aggressive grasses, it:
- Grows more slowly, so mowing frequency is lower once established.
- Forms a thick carpet that resists weeds when properly maintained.
- Handles heat and moderate drought reasonably well when roots are deep.
- Recovers from damage, but not as rapidly as couch or kikuyu, so heavy-wear spots may need extra care.
Within the zoysia group, different varieties have slightly different personalities:
- Empire zoysia: A popular, fine-leaf, dense variety that suits full sun and lightโmoderate traffic.
- Zoysia tenuifolia: Extremely fine-leaf, naturally mounding and best for ornamental or low-traffic areas.
Understanding this growth habit is the foundation of good zoysia grass care and maintenance: you are encouraging a dense, low-growing mat rather than forcing tall, lush leaf growth.
Core Zoysia Care: Mowing Height, Watering & Soil Preparation
Recommended Mowing Height for Zoysia Lawns
A key part of zoysia lawn care is keeping the mowing height in the โsweet spotโ for density and colour. As a guide:
- Empire zoysia: Around 25โ40 mm for most home lawns; slightly higher in shade or heat.
- Zoysia tenuifolia: Often kept a bit higher and shaped carefully over mounds and contours.
Follow the โone-third ruleโ: never remove more than a third of the leaf blade in a single mow. Cutting zoysia too short (โscalpingโ) exposes stems, thins the canopy and creates bare, straw-coloured patches that take time to recover.
Watering Zoysia Grass: Deep, Infrequent is Best
Zoysia prefers deep, less frequent watering over daily light sprinkles. Your goal is to train roots deeper, not keep the top centimetre constantly wet.
- Water only when needed โ when the lawn loses some spring underfoot and colour starts to dull.
- When you do water, aim for moisture to reach 100โ150 mm into the soil profile.
- Water early in the morning so leaves have time to dry, reducing disease risk.
Overwatering zoysia encourages thatch, shallow roots and disease; underwatering over a long period leads to patchy dormancy and thin coverage. Consistent, deep watering is one of the biggest levers in zoysia grass care.
Soil, Compaction & Thatch Management
Because zoysia is dense and slow-growing, soil structure and thatch control matter more than people expect.
- Soil prep: A well-prepared base of sandy loam or loam with good drainage sets the lawn up for life.
- Compaction: High-traffic areas can compress, restricting roots. Core-aerate these zones once every 1โ2 years.
- Thatch: Zoysia can build a spongy layer of thatch over time. Light de-thatching in active growth periods helps keep it in check.
Good soil structure, combined with correct mowing and watering, is the backbone of reliable zoysia lawn care and maintenance.
Zoysia Care Calendar: Seasonal Maintenance & Winter Care
A simple zoysia care calendar makes it much easier to keep the lawn looking consistent, instead of guessing each month. Adjust the exact timing to your climate, but the pattern stays similar:
- Late Winter โ Early Spring:
Gradually lower mowing height from winter setting, lightly tidy any thatch, and start deep watering as growth resumes. - MidโLate Spring:
Mow regularly at your target height. Check for weeds, lightly feed according to your fertiliser plan, and fix any compacted patches with spot aeration. - Summer:
Maintain mowing height (or raise slightly in extreme heat), water deeply but less often, and avoid heavy traffic on stressed areas. - EarlyโMid Autumn:
Keep mowing consistent, lightly top-dress low spots if needed, and carry out any core aeration while the lawn is still actively growing. - Late Autumn โ Winter:
Growth slows. Raise mowing height a notch, reduce watering frequency, and avoid aggressive de-thatching or renovation until warmth returns.
This pattern gives you a clear, repeatable framework for zoysia grass care and maintenance each year. Your fertiliser plan can then be layered on top of this calendar.
Empire Zoysia Lawn Care: Sun, Shade & Everyday Use
Empire zoysia care is all about balancing its dense, slow-growing habit with the amount of sun, water and foot traffic it receives.
For most home lawns:
- Light: Empire zoysia prefers full sun but can handle some lightโmoderate shade.
- Mowing: Aim for around 25โ40 mm, raising a little in shade or during hot, dry spells.
- Traffic: Regular family use is fine; very high wear zones may need extra aeration and care.
- Water: Deep, occasional watering to maintain root health, rather than shallow daily watering.
Consistent mowing and a seasonal care pattern do more for Empire zoysia lawn care than constant tinkering.
Keep it dense, not tall and straggly, and it will naturally resist many weeds and surface problems.
Zoysia tenuifolia Care: Mounded, Ornamental & Low-Traffic Lawns
Zoysia tenuifolia care is slightly different to Empire because this variety is often used as a
feature turf for contours, mounds and decorative spaces rather than a high-wear sports lawn.
- Use: Best suited to low-traffic areas, garden features and slopes where its natural mounding look can shine.
- Mowing: Often kept a little higher, with careful trimming to preserve the โbillowyโ appearance.
- Water: Similar deep, occasional watering to other zoysias, being mindful of runoff on steeper mounds.
- Weeds: Because leaves are so fine, keeping the canopy dense and healthy is your best weed defence.
The core principles of caring for Zoysia tenuifolia are the same: protect soil structure, avoid scalping,
water sensibly and carry out light, timely maintenance rather than heavy renovation.
Zoysia Grass Winter Care: Colour, Scalping & Recovery
Zoysia winter care is mostly about doing less, but doing it thoughtfully.
Being a warm-season grass, zoysia naturally slows down and may partially lose colour in colder months.
- Raise mowing height slightly to protect the crown and avoid exposing stems.
- Avoid aggressive de-thatching or renovation when growth is slow.
- Reduce watering in line with lower evapotranspiration โ donโt keep the soil soggy.
- Plan ahead: Any major correction work is better timed for late spring to early summer when recovery is faster.
With the right zoysia grass winter care, the lawn will come into spring ready to thicken and green up quickly,
rather than struggling to recover from winter damage.
Zoysia Lawn Care FAQ
Is zoysia easy to care for?
Once established, zoysia is generally considered low-maintenance compared with many other lawns.
It needs less frequent mowing, moderate feeding and a basic seasonal care routine to stay dense and tidy.
How often should I mow zoysia grass?
In active growth periods, aim to mow often enough that you never remove more than one-third of the blade at once.
Because zoysia is slower growing, this is usually less often than couch or kikuyu at the same height.
Does zoysia need a lot of water?
No. Zoysia prefers deep, occasional watering over constant light watering.
Once roots are established, it can tolerate short dry periods better than many cool-season grasses.
What is the difference between Empire zoysia and Zoysia tenuifolia?
Empire is a fine-leaf, dense lawn suited to regular use, while Zoysia tenuifolia is ultra-fine, naturally mounded
and best for ornamental, low-traffic lawns or design features.
How do I stop zoysia lawns getting thatchy and spongy?
Avoid over-fertilising, keep watering sensible instead of constant, and carry out light de-thatching or core aeration
during strong growth periods when the lawn can recover quickly.
What is the most important part of zoysia care?
Getting the basics right: correct mowing height, deep but sensible watering, good soil structure
and a simple seasonal calendar. Once those pieces are in place, zoysiaโs natural density does much of the work for you.
Use this guide as your base for zoysia care, then pair it with a dedicated fertiliser plan and a problems guide
to keep your Empire zoysia or Zoysia tenuifolia lawn consistently thick, soft and easy to live with year after year.
