Benefits of mulching
Which mulch types are best to use
Mulches can be organic or inorganic. What is the difference? Organic mulch is made from compostable materials like straw, cane sugar, barks, composted organic matter, etc. These materials break down after time and provide the soil with extra nutrients to aid plant health and growth. Wood chips such as pine bark and cypress mulch are larger in size and are ideal to let the water penetrate through to the underneath soil. They also take longer to break down and generally easier to spread due to their lightweight properties. Inorganic mulches are generally made from rock and pebbles. Popular rocks used are, river stones, white quartz, gravel and scoria. They don’t breakdown and are more suitable for front entrance gardens, small gardens around patios and pot plants to add some design highlights.
How thick do I mulch?
It depends on the material used. If you are using mulch from packaging, good suppliers will state on the back of the packaging the rate of application. Be careful not to mulch too thickly, the water needs to soak through to the underneath soil. Mulch that is applied too thick will act as a water barrier, water will soak into the mulch and not reach the soil and roots.
Mulch not to use
Lawn clippings are unpredictable. They can contain grass seed heads and weed seeds. Don’t risk it.
