Why Mulch Matters in Every Garden

Mulch is one of the most effective and low-effort ways to improve the health, look, and performance of your garden - helping plants thrive while reducing the time and effort you spend maintaining them. Whether you’re landscaping a coastal property, managing exposed soils, or simply trying to get more out of your garden - mulch works hard behind the scenes to protect, support, and elevate your space.

For us at Rochford, mulch is a core part of creating landscapes that not only look good but thrive long-term.

What Is Mulch?

Mulch is any material spread across the surface of your soil to protect and improve it. It can be organic - like bark, pea straw, or compost - or inorganic, like gravel or stone. The type you choose depends on your plants, soil type, climate, and aesthetic.

The Benefits of Mulching

1. Retains Moisture
Mulch helps your soil hold onto water. This reduces the frequency of irrigation and helps your plants survive hot, dry spells.

2. Suppresses Weeds
By blocking sunlight from the soil, mulch reduces weed germination - meaning less competition for your plants and less time spent weeding.

3. Improves Soil Health
Organic mulch breaks down over time, enriching the soil with nutrients and improving its structure for stronger, more resilient plant growth.

4. Regulates Soil Temperature
Mulch acts as insulation - keeping soil cooler in summer and warmer in winter. This helps protect roots and support steady growth year-round.

5. Lifts the Overall Finish
A fresh layer of mulch gives garden beds a tidy, resolved look. It defines spaces and highlights your plants, helping the whole landscape feel more intentional.

Choosing the Right Mulch for Your Landscape

Here are some of the mulches we most often recommend:

• Forest Floor Mulch – is made from NZ forestry byproducts and has a rich brown tone that sets off planting beautifully. Its mix of fine and coarse particles helps lock in moisture, control weeds, and stay in place, even on slopes or natural pathways. Great for home gardens, re-veg work, or adding structure to larger spaces.

• Bark mulch or wood chips – Long-lasting and great around shrubs, trees, or ornamental beds.

• Pea straw or lucerne – Ideal for edible gardens; breaks down quickly and feeds the soil.

• Compost mulch – Rich in nutrients, good for flower beds, though it needs topping up more often.

• Arborist Mulch – Aged, chipped mulch sourced from local arborists. Natural in appearance and ideal for garden beds or revegetation zones. It helps suppress weeds, retain moisture, and blend seamlessly into planted areas. Tip: apply sheep pellets around desirable plants before laying this mulch - it offsets nitrogen drawdown as the mulch breaks down and gives plants an early nutrient boost.

• Gravel or stone – Great for dry zones, modern garden styles, or low-maintenance areas.

We choose mulch based on the conditions of each site - whether it's sandy, clay-based, newly planted, or part of a mature landscape.

Why We Use Mulch in Our Projects

We include mulch in almost every planting plan because it delivers results - quickly and over time. It supports healthy planting, improves soil, and finishes a space with clarity.

Mulching is a low-effort, high-reward habit that every gardener should embrace. Whether you're after stronger growth, less maintenance, or a sharper finish - it’s one of the easiest ways to lift your landscape.
