Mulch is anything purposefully layered on soil to protect plants, nourish them, and decorate your garden.
Usually made with natural products, mulching is very beneficial to plants and landscaping. In addition, it helps deal with that most tedious garden chore: weeding!
More than just a decorative ornament, mulch is totally nature-friendly – and wallet-friendly!
Mulch reproduces nature’s way of working: soil should never stay bare. Always keep those vegetable and flower beds covered!
Advantages of mulching
Mulch is one of today’s most trendy products, and it isn’t only because it looks great!
Thanks to the thick opaque layer that mulch forms on the soil surface, it prohibits weed seed germination and thus indirectly avoids the use of herbicides – all of which are chemical-based.
- It is an amazing protection against winter frost spells and freezing cold!
A layer barely 1 to 2 inches (3 to 4 cm) thick is enough to protect roots from freezing, especially for potted plants.
It will keep the root system in top form to burst with life in spring.
- All plant-based mulches are a 100% natural fertilizer!
As they slowly break down, they will enrich the soil with important nutrients that will boost your plantation’s development.
- In avoiding water evaporation on hot summer days, you will save on watering and lighten the burden on the environment, which is pretty critical as regards water in the summer season.
There are 2 major types of mulch
First type: Mineral mulch
Mineral mulch makes for an orderly, controlled garden. The mulch is mineral in the sense that it comes from rocks, gravel or other hard materials. It’s easy to choose striking colors. The appearance of the garden bed or pot will stay constant as time goes by.
Second type of mulch: Plant-based mulch
This includes all types of mulch derived from plants. Abundant and renewable, these mulches always make the soil richer and plant-friendly as time passes. It must be renewed yearly or every two years, since it naturally breaks down with time. It provides nutrients and reduces the need for fertilizer.
Although not mulch in the actual sense, green manure is one way to perform the same functions as mulch, but only for a season.
- You can make these yourself with a chipper-shredder from hedge trimmings or shrub pruning waste.
To sum it up
Each type of mulch has specific advantages. Mineral mulch excels at keeping weeds away. Plant-based mulch releases nutrients as it breaks down.
Quantities differ for each as well. For example, mineral mulch will usually require only 1 to 2 inches (3 to 5 cm) of mulch to be effective, whereas for plant-based mulch, the more the merrier! It’s even possible to stack up to a foot (30 cm) of plant material if you’re starting a growing bed in poor soil!
You’ll have understood by now that mulching boasts many advantages, and is among those products that can easily replace others that don’t necessarily respect our planet.
Mulch attracts birds in your garden
Since mulch creates a favorable environment within the ecosystem, such animals as worms, larvae, and insects will be attracted to it.
Birds will then come to feed on those.
Mulching thus enriches your garden’s ecosystem, and gives our bird friends a great nutritious pantry, especially in winter.
Some plants are not comfortable with mulch
Among these mulch-rejecting plants are Mediterranean-native plants, that can benefit from some mulch during summer, but only a thin layer. Succulents or rock plants, need dry soil, sometimes even arid.
Smart tip about mulch
If you only have small batches of mulch material, you can pack it around a few plants and create a patchwork in your garden beds!
