Common Kikuyu Grass Problems and How to Fix Them

Common Kikuyu Grass Problems and How to Fix Them

Even the toughest lawn can develop problems. Here are the most common Kikuyu grass problems in Cape Town and how to fix them.

Bare Patches

Bare patches are usually caused by heavy foot traffic, pet damage, disease or poor soil. To fix bare patches, loosen the soil in the affected area, add some compost and topsoil, and either lay new Kikuyu rolls or encourage the surrounding grass to spread by keeping the area moist and fertilised.

Yellowing Grass

Yellow Kikuyu grass is usually a sign of nitrogen deficiency, over-watering, poor drainage or iron deficiency. Apply a balanced lawn fertiliser with iron, improve drainage if necessary, and adjust your watering schedule. If the yellowing is widespread, a soil test can help identify the specific deficiency.

Thatch Build-Up

Thatch is a layer of dead grass stems and roots that builds up between the soil surface and the green grass blades. A thin layer of thatch is normal, but thick thatch can prevent water and nutrients from reaching the roots. Dethatch your lawn in spring using a scarifier or by vigorous raking.

Fungal Disease

Kikuyu can be affected by various fungal diseases, particularly in warm, humid conditions or when over-watered. Signs include brown or grey patches, a powdery coating on the grass blades, or a ring pattern in the lawn. Treat with a fungicide and improve air circulation and drainage.

Invasive Spreading

Kikuyu's vigorous spreading habit is a benefit in the lawn but a problem in garden beds. Edge your lawn regularly and use physical barriers such as lawn edging strips to contain the grass.

Slow Winter Growth

Kikuyu naturally slows down and may go semi-dormant in winter. This is normal and not a problem. Reduce mowing and watering and the lawn will recover fully in spring.
