Cape Town’s summers are famous for their beauty, but also for their intense heat and recurring water restrictions. For property owners, businesses, and homeowners alike, managing gardens and trees in a sustainable, water-conscious way is essential. By adopting water-wise landscaping practices, you not only protect your outdoor spaces but also contribute to conserving one of South Africa’s most precious resources.
Why Water-Wise Landscaping Matters
Cape Town has faced severe droughts in the past, and water management continues to be a priority for residents and businesses. Water-wise gardening reduces consumption while still maintaining healthy, attractive landscapes. According to the Department of Water and Sanitation, outdoor irrigation accounts for a significant portion of household water use, making smarter garden practices critical.
Key Water-Wise Practices for Trees and Gardens
- Mulching – Applying a thick layer of organic mulch around trees and garden beds reduces evaporation, regulates soil temperature, and prevents weed growth. It’s one of the simplest, most effective water-saving techniques.
- Choose Indigenous and Drought-Resistant Trees – Species like the Wild Olive (Olea europaea subsp. africana) or Cape Ash (Ekebergia capensis) are naturally adapted to Cape Town’s climate. They thrive with minimal water compared to exotic species.
- Irrigate Smartly – Water deeply but infrequently. Early morning or late evening irrigation reduces evaporation. Drip irrigation systems are especially efficient for trees and shrubs.
- Group Plants by Water Needs – Planting trees and shrubs with similar requirements together makes irrigation more efficient and avoids unnecessary water use.
- Prune to Reduce Stress – Regular pruning removes weak or overcrowded branches, helping trees use water more effectively by directing resources where they are needed most.

- Lower water bills
- Healthier, more resilient trees
- Compliance with municipal water restrictions
