2GreenLM Berea is the grass people buy when kikuyu has failed under a tree, and it is usually the right call. It is also the grass most often laid in the wrong place, because the thing it is worst at is the thing nobody asks about at the nursery.
What it is
LM Berea is Dactyloctenium australe, an accepted botanical name with no reclassification to worry about, unlike kikuyu. LM stands for Lawn Master. It is a warm-season grass that spreads by surface runners, and it is almost always laid as instant lawn rather than seeded.
Why it wins in shade
Of the common South African lawns, LM Berea has the best shade tolerance. Roll On Lawn in Cape Town rates it highest of the grasses they sell and calls it the most sustainable of their lawns, and it is the one grass that will hold a reasonable cover under a mature oak where kikuyu goes thin and bare.
That is the entire case for it, and it is a strong one. In the older Paarl suburbs, where the oaks in Courtrai and Klein Parys throw deep summer shade, it is frequently the only real lawn that works.
The traffic problem
Here is the part the shade case tends to bury. Christians, Patton and Law, a standard turfgrass textbook, describes LM Berea as intolerant of both frost and traffic, and slow to recover from injury. Those two together are the real difficulty: a lawn that wears thin and then repairs slowly does not carry a family.
There is a botanical reason. Flora of Australia records the species as stoloniferous with rhizomes absent. It runs on the surface only, with no underground reserve to regrow from once the surface is gone. Kikuyu has both, which is exactly why kikuyu bounces back from a worn patch and LM Berea does not.
Roll On Lawn rates its traffic tolerance poor outright and says no dogs and no heavy sports. Worth noting that suppliers do not agree here: ClicknPlant describes Berea as tolerant of medium levels of traffic. We are reporting the disagreement rather than averaging it, and our own experience is closer to the cautious end.
The washing line test
If a route through the lawn gets walked every day, LM Berea will show it and will not close the gap on its own. Either put a path in, or accept a worn line. This is the single most common reason a shade lawn disappoints.
Water, roots and a dry Paarl summer
LM Berea is not a drought grass. Roll On Lawn rates its drought tolerance only fair and notes a very shallow root system, and they add a detail worth carrying: it grows well in KwaZulu-Natal because of the humidity and an annual rainfall of around 880mm.
That is a humid, summer-rainfall origin, and Paarl is neither. In a rainless Cape February a shallow-rooted grass under a tree is competing with the tree for water in the top layer of soil, and the tree wins. If you lay LM Berea here, plan the irrigation for it rather than assuming shade means less water.
When to lay it in the Cape
Spring, roughly September to November. LM Berea is warm-season and frost-sensitive, and it is slow in the cold, so it wants a full warm season in the ground before it meets a Cape winter.
This is the one place where our advice differs from what we say about kikuyu, which we would rather lay in autumn here so the winter rain establishes it. LM Berea cannot use that window, because it will sit and sulk through the cold instead of rooting. Mayford's sowing guidance draws the same line: spring and summer only where there is frost, and Paarl has frost.
Easycare Grass in Cape Town makes the same point from the other side, noting that buffalo and LM Berea are both tricky at the peak of winter because frost affects them more than kikuyu or cynodon does.
Mowing
Do not cut it short. Yates notes LM Berea will not take close mowing, and Roll On Lawn gives a blade length of 50 to 70mm. A broad-leafed surface runner mown down to kikuyu height is being scalped, and because there are no rhizomes underneath, it recovers badly. Set the mower high and leave it there.
If you are choosing between this and kikuyu, our head to head comparison sets the two against each other on shade, traffic, water and cost. If the shade is so deep that even LM Berea struggles, artificial grass is the honest answer.
Frequently asked questions
Is LM Berea good for shade?＋
It is the best of the common South African lawns for shade, and under a mature tree it is usually the only real grass that holds. Roll On Lawn in Cape Town rates it highest of the lawns they sell. In very deep shade even LM Berea thins, and at that point artificial grass or a groundcover is the more honest answer.
Can LM Berea take dogs and children?＋
Not well. A standard turfgrass textbook describes it as intolerant of traffic and slow to recover from injury, and Flora of Australia records that it has no rhizomes, so there is no underground reserve to regrow from once the surface wears. Roll On Lawn rates its traffic tolerance poor and advises no dogs or heavy sports, though ClicknPlant rates it as tolerating medium traffic. Suppliers genuinely disagree, and we would plan for the cautious view.
When should LM Berea be laid in the Western Cape?＋
Spring, roughly September to November. It is a warm-season grass, frost sensitive and slow in the cold, so it needs a full warm season to root before it meets a Cape winter. This differs from kikuyu, which we would rather lay in autumn here so the winter rain does the establishing.
How short should I mow LM Berea?＋
Long. Yates notes it will not take close mowing, and Roll On Lawn gives a blade length of 50 to 70mm. Cutting it down to kikuyu height scalps it, and with no rhizomes underneath it recovers slowly. Set the mower high and leave it there.
Does LM Berea need less water than kikuyu?＋
No. Roll On Lawn rates its drought tolerance only fair, against high for kikuyu in the University of California IPM tables, and notes a very shallow root system. They also point out it does well in KwaZulu-Natal on humidity and about 880mm of rain a year, which is a wetter, more humid climate than Paarl. Under a tree it is also competing with the tree for water in the top of the soil.
Is LM Berea the same as LM grass?＋
Yes. LM stands for Lawn Master, and LM grass, LM Berea and Berea are used interchangeably for Dactyloctenium australe in the South African trade. You will see all three on supplier price lists for the same product.
