1. Weeds Are Taking Over
One of the primary benefits of mulch is weed suppression. If you notice weeds sprouting through your mulch, it’s a sign that the layer has thinned out or decomposed. A fresh layer of mulch helps block sunlight from reaching weed seeds, preventing them from germinating.
What to do:
Add a fresh 5–7 cm (2–3 inch) layer to smother weeds and protect your soil.
2. The Soil Is Drying Out Quickly
Mulch retains moisture by reducing evaporation and keeping the soil cool. If your garden soil is drying out faster than usual, even with regular watering, your mulch may no longer be doing its job. Adding a fresh layer will help maintain consistent moisture levels.
What to do:
Top it up to help your soil hold moisture longer and reduce watering needs.
3. Mulch Has Thinned or Washed Away
Over time, mulch naturally decomposes or gets displaced by wind and rain. If you notice bare patches or a significantly thinner layer, it’s time for a mulch refresh. Maintaining a 5-7 cm (2-3 inch) layer ensures proper insulation and soil protection.
What to do:
Keep mulch at 5–7 cm thick for best results. Thin layers won’t insulate or protect the soil properly.
4. Soil Compaction Affects Plant Growth
Compacted soil restricts water, air, and nutrient movement, making it harder for plant roots to thrive. Mulch helps prevent soil compaction by creating a protective buffer. If your soil feels hard and compacted, adding a fresh layer of mulch can improve its structure and aeration.
What to do:
Add mulch to reduce compaction and improve airflow and water movement in the soil.
5. Mulch Looks Faded and Decomposed
Organic mulch breaks down over time, enriching the soil with nutrients. However, once it loses its rich colour and starts to crumble, it’s time to refresh it. Fresh mulch not only boosts soil health but also enhances your garden’s appearance.
What to do:
Remove any crusted or decomposed mulch, then apply a fresh new layer. Your garden will look better and grow stronger.
How to Refresh Your Mulch the Right Way
- Remove any matted or decomposed mulch – This prevents mould and pests.
- Replenish with a new 5-7 cm (2-3 inch) layer. Too much mulch can suffocate plants.
- Keep mulch away from plant stems – This reduces the risk of rot and pest infestations.
- Choose high-quality mulch – Using premium mulch ensures longer-lasting benefits.
