1. Assess and Clean Up
Begin by assessing your garden. Remove any annual plants that have completed their life cycle and clear away dead foliage and weeds, which can harbour pests and diseases. This is also a great time to collect, and compost leaves to create a nutrient-rich soil conditioner. With the change in the season, even the weeds take a break by shedding all their seeds, so now is the time to weed weed weed!
2. Prune and Divide
Late autumn is ideal for pruning many shrubs and trees, as it helps prevent the spread of disease and encourages root growth. However, be cautious with spring-flowering shrubs, as pruning them now could remove their spring blooms. It’s also an opportune time to divide perennials. Dividing helps to control the size of your plants, encourages healthy growth, and increases the number of your plants.
3. Plant Spring Bulbs
For a vibrant spring display, autumn is the time to plant your bulbs. Johannesburg gardeners should consider planting daffodils, tulips, and hyacinths before the first frost. Planting now allows the bulbs to establish roots and ensures a burst of colour in the spring.

4. Mulch for Protection
Applying a layer of mulch around your plants can provide protection from the cold and help retain soil moisture. Organic mulches like straw, bark, or compost protect and enrich the soil as it decomposes.
5. Lawn Care
Rake any leaves off the lawn to prevent mould and diseases. Autumn is also a good time to aerate your lawn, allowing oxygen, water, and nutrients to penetrate the soil more easily. Set your mower down a notch for a close crop, encouraging root growth for a lush lawn later in the year. Consider applying a high-potassium fertiliser to strengthen the grass ahead of winter.
6. Protect Sensitive Plants
Identify plants that are sensitive to frost and consider moving potted ones to a more sheltered spot. Cover those in the ground with frost cloth or straw to provide extra warmth.
7. Harvest and Plant Vegetables
Harvest any remaining summer crops and clear out spent vegetable plants. Plant cold-hardy vegetables like kale, spinach, and broad beans, which can grow during Johannesburg’s mild winter. Nothing beats making a winter soup from your own veggie patch, both in taste and bragging rights.
8. Water Wisely
Although Johannesburg’s winter is dry, overwatering can still be problematic, especially as plants require less water during the cooler months. Adjust your watering accordingly, focusing on early morning watering to prevent evaporation loss.

9. Prepare Garden Tools and Infrastructure
Clean,sharpen, and oil your gardening tools so they’re ready for spring. It’s also a great time to repair damaged fences, trellises, or paths. This preparation can make spring gardening much smoother.
10. Plan for Next Season
Finally, autumn is a great time to reflect on what worked in your garden and what didn’t. Start planning for the next growing season, considering crop rotation and new plants to introduce. By following these autumn gardening tips, Johannesburg gardeners can ensure their gardens are well-prepared for the winter, paving the way for a lush and healthy garden come spring. Happy gardening!
