2GreenKikuyu is the default South African lawn, and most of what is written about it is written to sell it. This is the version with the disadvantages left in: what it is genuinely good at, the way it spreads, the one legal detail almost nobody mentions, and why laying it in Paarl works best at the opposite end of the year to the advice you will read from Gauteng.
Two names, and why both still matter
The accepted botanical name is Cenchrus clandestinus. World Flora Online resolves the older Pennisetum clandestinum, and Kikuyuochloa clandestina, as synonyms of it.
You will still see the old name everywhere, and that is not sloppiness. South African law uses it: the 2020 invasive species list gazettes kikuyu as Pennisetum clandestinum. Cape growers use it too. So both names are current in practice, and a supplier writing Pennisetum on an invoice is not out of date.
Is kikuyu legal to plant in South Africa?
Yes, in an ordinary garden. This comes up because kikuyu does appear on the national invasive species list, and half-remembered versions of that fact circulate without the part that matters.
Entry 262 of the National List of Invasive Terrestrial and Fresh-water Plant Species, published as Notice 1003 in Government Gazette 43726 on 18 September 2020, lists kikuyu as Category 1b in Protected Areas and in wetlands where it does not already occur, and then says: not listed elsewhere. The notices took effect thirty days after publication.
So for a garden in Paarl, laying a kikuyu lawn is not a restricted activity. The listing bites inside protected areas and wetlands, and the limb worth knowing about is the prohibition on allowing the spread. If your property runs down to a river course or a wetland, that is the one to take seriously, and along the Berg River it is not hypothetical.
A neat detail in the gazette
The notice states that where a scientific name changes or is misspelt, the common name decides whether a species is listed. So the move from Pennisetum to Cenchrus changes nothing: the listing is anchored on the words kikuyu grass.
What kikuyu is actually good at
Two things, and it is genuinely the best common lawn at both.
- โWear and recovery. The University of California IPM turf tables rate kikuyu high for wear tolerance. It takes dogs, cricket and a path to the washing line, and it repairs itself faster than anything else on the list because it runs on both surface stolons and underground rhizomes.
- โDrought. The same tables rate kikuyu high for drought tolerance, above St Augustine, which is what South Africa sells as buffalo. This is the opposite of how the two are usually sold here. Kikuyu browns off and comes back rather than staying green, which reads as failure and is not.
Where kikuyu fails: six hours of sun
Kikuyu wants a minimum of six hours of direct sun a day. Evergreen Turf, Kikuyu Guru and Cape Contours all publish that same floor, and below it kikuyu thins, goes patchy and eventually gives up. UC IPM rates its shade tolerance moderate, which is more generous than the trade, but that is about light shade, not the deep shade under a mature Paarl oak.
The trap is that shade arrives slowly. Lawn Solutions Australia makes the point well: a new garden often has plenty of sun, and then the trees you planted grow. A kikuyu lawn laid in an open new-build can be in trouble in eight years without anything having gone wrong.
If the spot has less than six hours, the honest answer is a different grass. Our lawn grass comparison sets out the alternatives, and under real shade it is LM Berea.
The spreading nobody warns you about
Kikuyu is aggressive, and the numbers are worth seeing. UC IPM records an uncontested patch expanding by about 0.37 square metres a month, shoots growing more than 25mm a day, and rhizomes running 25 to 100mm underground. It notes that kikuyu invades ground covers and flower beds and often chokes them out entirely.
The detail that catches people is this: a chopped section of stem can root. So hoeing along a bed edge does not contain kikuyu, it propagates it. What contains kikuyu is a physical edge, and a bed that is dug rather than chopped.
Thatch is the other tax
UC IPM lists heavy thatch, scalping and invasiveness as kikuyu's special problems, and notes the coarse blade makes it harder to mow cleanly. Thatch is why an annual top-dressing and a scarify matter more on kikuyu than on any other lawn here.
When to lay kikuyu in the Cape
This is where most advice you will find is wrong for Paarl, because it was written for Gauteng.
The Highveld gets its heat and its rain at the same time, so the Gauteng rule is to lay in spring, September to November, into the coming summer rains. Paarl inverts that. Rain falls May to August, and the heat arrives with a long rainless stretch. Laying in spring here drops a new lawn into the dry season and puts it entirely on your irrigation.
Lawn Care Plus, a Johannesburg firm, splits its own advice on exactly that line and puts the Western Cape at autumn, March to early May, with the soil still warm from summer and the rains about to start. Lay-A-Lawn in Kuilsrivier makes the water case plainly: plant in the colder months and the lawn grows slowly, but the rainy season does the watering, and by the time the heat arrives it is established.
The Cape rule of thumb
Autumn, March to early May, is the cheapest time to lay kikuyu in Paarl, because the winter rain establishes it for free. Spring works, but you pay for it in irrigation through the first summer.
Lay-A-Lawn also notes that kikuyu does not go fully dormant through a Cape winter, so instant lawn can go down year round here. That is a real difference from the Highveld, where a frosted lawn is genuinely asleep.
Living with it: water, mowing and winter
Kikuyu grows fast, so it is mown often, and it is the one lawn where a missed fortnight shows. Feed it and it grows faster, which is not always what you want. Our patchy lawn rescue plan sets out the order to work in if it has gone backwards, and the short version is that feeding is near the end of that list, not the start.
In winter kikuyu browns off in the cold and after frost, then greens up in spring. UC IPM rates its cold tolerance low, so a Paarl frost pocket will brown earlier and harder than a sheltered garden two streets away. It is dormancy, not death. Our Western Cape garden calendar puts the spring recovery jobs in order.
If you want it laid rather than lived with, our instant lawn service supplies and lays kikuyu across Paarl and the Winelands, and the instant lawn calculator works out the square metres and the dressing you need.
Frequently asked questions
What are the disadvantages of kikuyu grass?๏ผ
It spreads into beds and chokes ground covers, and University of California IPM measures an uncontested patch expanding about 0.37 square metres a month with shoots over 25mm a day. A chopped stem section can root, so hoeing an edge spreads it. It builds heavy thatch, needs frequent mowing, browns off in cold and frost, and it needs at least six hours of direct sun, so it fails under mature trees.
What is kikuyu grass good for?๏ผ
Full-sun lawns that take real use. University of California IPM rates it high for both wear tolerance and drought tolerance, and it repairs faster than the other common lawns because it runs on surface stolons and underground rhizomes. If you have children, dogs or a route people actually walk, and six hours of sun, kikuyu is the sensible choice.
When should I plant kikuyu in South Africa?๏ผ
It depends where you are, and most advice online is written for the summer-rainfall Highveld. In Gauteng, spring, September to November, lines up with the summer rains. In the winter-rainfall Western Cape it is the opposite: autumn, March to early May, lets the winter rain establish the lawn for you instead of your irrigation doing it through a dry summer.
Is kikuyu grass illegal in South Africa?๏ผ
No, not in an ordinary garden. Kikuyu is listed as Category 1b in the 2020 national invasive species list, but only in Protected Areas and in wetlands where it does not already occur, and the entry says it is not listed elsewhere. Laying a kikuyu lawn in a Paarl garden is not a restricted activity. The part to take seriously is the prohibition on allowing it to spread, which matters if your property runs down to a river or a wetland.
Why does my kikuyu lawn go brown in winter?๏ผ
It is dormancy. University of California IPM rates kikuyu low for cold tolerance, so it browns off in cold weather and after frost, then greens up again in spring. A frost pocket browns earlier and harder than a sheltered garden nearby. A light top-dressing and a feed in early spring speeds the recovery.
Does kikuyu need a lot of water?๏ผ
Less than it is given credit for. University of California IPM rates its drought tolerance high, above St Augustine, which is what South Africa sells as buffalo. The confusion is that kikuyu goes brown under drought rather than staying green, so it looks worse while actually surviving better. Feedipedia notes it does best where annual rainfall is above 800mm, which puts Paarl at the lower edge of comfortable.
How do I stop kikuyu spreading into my beds?๏ผ
A physical edge, and do not hoe it. University of California IPM notes that a chopped stem section can root, so chopping along a bed edge propagates kikuyu rather than containing it. Dig the runners out with the crown attached, and put in a proper edge, whether that is a mowing strip, steel edging or a paved band.
