After the generous rains of December 2024, which gave our gardens a well-deserved soaking, January 2025 has brought back the heat and drier conditions. This transition from high rainfall to drier spells is typical of late summer in Gauteng, making it a critical time for landscapers and homeowners to adjust their garden care strategies. Whether you’re managing a residential oasis or a large-scale landscape, taking the right steps now will ensure a resilient, waterwise, and beautiful garden moving into autumn.
Focus on Soil Health
With the summer rains behind us, soil structure may be compacted or leached of nutrients. Now is the time to:
Mulch Heavily: Apply a thick layer of mulch around plants to retain moisture, regulate soil temperature, and suppress weeds. Indigenous mulch materials such as bark chips, dried leaves, or straw work best.
Replenish Nutrients: Use organic compost or slow-release fertilizers to restore lost nutrients. A light application of organic fertilizer, such as a kelp-based product, can boost plant resilience.
Adjust Watering Schedules
The shift from wet to dry conditions means watering habits need to change:
Deep, Less Frequent Watering: Water early in the morning to reduce evaporation and encourage deep root growth.
Check for Drainage Issues: Heavy rains may have compacted some areas, leading to water runoff rather than absorption. Loosen the soil where necessary.
Irrigation System Check: Ensure your irrigation system is set to meet the changing water needs, focusing on efficient drip irrigation rather than overhead sprinklers.
Late Summer Pruning & Maintenance
As plants move toward autumn growth patterns, pruning and shaping become essential:
Trim Back Overgrown Indigenous Shrubs: Species such as Aptenia cordifolia (Pink Carpet) and Leonotis leonurus (Wild Dagga) benefit from a light trim to encourage compact, healthy growth.
Deadheading & Thinning: Remove spent flowers from Agapanthus, Bulbine frutescens, and other summer bloomers to promote a longer flowering season.
Weeding & Pest Control: Late summer is notorious for weeds and pests. Hand weeding and eco-friendly pest control methods (such as neem oil sprays) help keep your garden in balance.
Refreshing Indigenous Flower Displays
Many indigenous plants are still in full bloom, but some may need extra care:
Encourage Flowering Perennials: Gazania rigens and Scabiosa africana can be lightly fed and deadheaded for extended blooming.
Prepare for Autumn Planting: Start planning for indigenous bulbs such as Crinum macowanii (River Lily), which thrive when planted in late summer for autumn growth.
Lawns: Maintain, but Don’t Overdo It
Gauteng’s summer grass, such as Cynodon dactylon (Kweekgras), has enjoyed the rains but now needs careful management:
Mow Less Frequently: Keep lawns slightly longer to retain moisture and reduce stress.
Aerate Compact Soil: This allows water to penetrate more effectively and prevents surface runoff.
Minimal Fertilizing: Avoid over-fertilizing now, as excessive nitrogen can encourage weak, thirsty growth in the dry months ahead.
Encourage Biodiversity & Habitat Gardening
Now is an excellent time to support wildlife in your garden:
Bird-Friendly Water Features: A small birdbath or shallow water source will help wildlife through the drier spell.
Indigenous Shrubs for Pollinators: Tecoma capensis (Cape Honeysuckle) and Halleria lucida (Tree Fuchsia) provide nectar for birds and insects.
Habitat Piles & Rockeries: Leaving a section of garden untamed with logs and rocks provides shelter for beneficial insects and small reptiles.
Final Thought: Sustainability & Smart Landscaping
As we move from a wet December to a drier late summer, embracing waterwise landscaping is key. A well-mulched, indigenous, and carefully managed garden will not only survive but thrive in the months ahead.
