Autumn Gardening

We're a couple of weeks into autumn and, while the air hasn't cooled much during the day yet, it soon will. And with that usually comes the temptation to retreat indoors, which means the garden could slip down your priority list.

By stepping back now could cost you later. Autumn provides a critical window for setting your garden up to thrive in summer. This is when the groundwork is laid, and a well-timed clean-up, smarter watering and starting your compost heap now will make a real difference come summer.

Five common mistakes that are easy to make in autumn but quietly come back to bite when it matters most:

1. Letting leaves pile up In many parts of South Africa, particularly the Highveld, Cape Winelands and KZN Midlands, autumn leaf drop is significant. Allowing leaves to build up can suffocate your lawn and create the perfect conditions for pests and disease, blocking sunlight, trapping moisture, and weakening grass before winter dormancy even begins.

What to do instead: Clear leaves regularly using a rake or tools like the Gardena Leaf and Lawn Collector, then repurpose them as mulch or add them to your compost heap rather than throwing them away.

2. Getting composting wrong Autumn through early spring (April–September) is prime composting season, but many gardeners get the balance wrong when building a compost pile. Heaps made of mostly dry leaves without enough green material slow decomposition, while skipping composting altogether means missing out on organic matter that enriches garden soil before planting season.

What to do instead: Mix dry leaves with green garden waste or kitchen scraps, and turn your compost regularly. Gardena tools like the NatureLine Spade or Spading Fork to help make the job easier.

3. Overwatering Many gardeners keep watering out of habit, while others cut back too sharply, leaving plants struggling. In South Africa, where water conservation is a priority and rainfall can be unpredictable, getting that balance right matters. Too much water in autumn can lead to root rot, fungal issues and unnecessary waste, while too little can leave plants stressed and unable to build strength ahead of winter.

What to do instead: Scale back gradually rather than stopping suddenly, and always check soil moisture first. Tools like Gardena Water Controls, sprinklers or a Micro Drip System can help you water more precisely and avoid overdoing it.

4. Neglecting your tools Autumn is a demanding season for garden tools; pruning, cutting back, and clearing all need doing. It’s also when they’re often neglected. Dirty or blunt tools don’t just make the job harder. They can damage plants, spread disease and set back growth in spring.

What to do instead: Use the correct pruning tool from the Gardena secateur, lopper and hedge clipper range. Secateurs to be used for young green shoots, loppers for thicker dry wood and hedge clippers for overgrown and unruly hedges. After use ensure your tools are clean, keep blades sharp and store them properly. 

5. Neglecting your autumn clean-up Perhaps the biggest mistake is doing nothing at all. An autumn clean-up isn’t about perfection. It’s about preparation. Removing dead material, cutting back, and tidying beds help prevent pests, support healthy regrowth and set your garden up for spring.

What to do instead: Don't try to tackle it all at once; little and often is the key. Clear leaves, remove debris and cut back where needed as you go. Gardena tools like the secateurs and combisystem range will help to get the job done. 

A well-prepared autumn garden largely takes care of itself through winter and thrives come summer. It's just about doing the right work at the right time. Get these five things in place now, and winter becomes the easy season it's supposed to be.

South African summers are made for outdoor living, a garden worth showing off starts with what you do this autumn.
