Eucalyptus mulch is one of the most popular choices for Victorian gardens, it looks great, smells fresh and does wonders for moisture retention and weed control. If you’re creating a new garden or topping up existing beds, eucalyptus mulch is the perfect way to give your outdoor spaces a natural finish while improving soil health.
At Bittern Garden Supplies, we’ve helped countless locals choose and maintain the right mulch, so here’s our top tips on storage and upkeep.
Why Choose Eucalyptus Mulch?
Eucalyptus mulch offers a balance of practical and aesthetic benefits. Its natural oils deter pests, making it an eco-friendly way to protect your plants. The fine texture helps it knit together once laid, reducing movement in windy weather and its earthy tones bring a uniform, stylish finish to garden beds.
As it breaks down slowly, eucalyptus mulch enriches the soil over time without needing constant top-ups. No wonder it’s a favourite across the Mornington Peninsula for gardeners looking for a combination of functionality and beauty.
Storing Eucalyptus Mulch the Right Way
If you’re buying in bulk, proper storage is essential to keep your mulch fresh and usable until you’re ready to spread it.
Moisture is the enemy of stored mulch. If your eucalyptus mulch sits wet for long periods before use, it can start to decompose prematurely or grow mould. Always store mulch in a dry location, ideally under a tarp or in a shed.
Covering your mulch pile is important but avoid sealing it too tightly. Trapped moisture and lack of ventilation can lead to sour mulch a condition where the mulch starts to ferment and release harmful acids. Instead, loosely cover the pile so air can circulate while still protecting it from rain.
Never dump your mulch directly on soil or lawn. It can absorb ground moisture and start breaking down before you’ve even laid it. Instead, use a tarp, timber pallets or concrete as a base.
While eucalyptus mulch stores better than some finer mulches, it’s still best to use it within a few weeks or months. Buying only what you need for the season is the simplest way to keep it fresh.
How to Maintain Mulch in Your Garden
Once you’ve laid down your mulch, maintenance is straightforward but essential if you want to enjoy the full benefits.
Keep mulch at the right depth
Aim for a layer about 5–7cm thick. Too thin, and weeds will creep through. Too thick, and your soil may struggle to breathe, which can suffocate plant roots.
Avoid piling mulch against stems
Leave a small gap around the base of trees, shrubs, and plants to prevent rot. Mulch should protect, not smother.
Top up as needed
Over time, your mulch will slowly break down and settle. Add a fresh layer once or twice a year to maintain an even look and consistent performance.
Stir it up
Every few months, give your mulch a light rake to loosen compacted sections, this keeps airflow moving and ensures water can filter through to the soil below.
