Black Forrest® spreading throughout New Zealand

Following a soft launch last spring, Wholesale Landscapes has seen extreme growth in demand for a product which delivers a sophisticated visual appeal combined with all the garden-health benefits of a mulch. The ground-breaking and innovative Black Forrest® was exclusively developed by Wholesale Landscapes, the Nelson-based company which is the South Island’s largest manufacturer of landscaping products. Now, Black Forrest® is trending as the ‘must-have wow factor’ for garden groundcover.


Several years ago when one of Wholesale Landscapes’ products achieved triple the demand over supply, the Wholesale Landscapes team had to go back to the drawing board. Wholesale Landscapes’ bark product Chocolate Mini Chip, a fine dark-coloured bark medium derived mainly from radiata pine, was used all over the South Island for a range of uses, from potting mix recipes to the final finishing touches in landscaping new homes. Local increases in construction and the growth of horticulture saw demand for Chocolate Mini Chip outstrip supply.


Wholesale Landscapes undertook vigorous market research into the features consumers liked about Chocolate Mini Chip. Then Wholesale Landscapes set itself a challenge – to fulfil customers’ requirements with an alternative product, providing better value and improved features, whilst being produced in a more sustainable way.


Ben Homan, National Sales Manager at Wholesale Landscapes, explains it this way:

“Our market research indicated that customers liked the mulching, colour, and durability properties of the Chocolate Mini Chip, so it was on these three features that Wholesale Landscapes focussed. We knew we had to look at sources other than bark, which had varying supply throughout the year. It was at this stage that testing on a variety of wood products took place, with the aim of alleviating the pressure of demand on decorative barks.”


The question this raised was – how do you go about making a wood-based product black, while retaining all the other features customers valued? Wholesale Landscapes discovered the solution lay in an all-natural, carbon-based, durable jet-black colourant being applied, through a computer-monitored process, to a small pine flake, sustainably-sourced from forestry waste. Following a further nine months of research and development to tweak it to perfection, Black Forrest® was market-ready.


After local councils, landscapers and lifestyle gardeners began using the product, feedback was very positive, resulting in a powerful word-of mouth marketing response which saw Wholesale Landscapes having to ramp-up production. 

Black Forrest® is a premium, purpose-built, decorative mulch with jet-black colour, derived from a safe, toxin-free, environmentally-friendly, water-based colourant. It provides the key to a fashionable modern-style ground covering with the corollary benefits of weed suppression and moisture retention. This mulch also improves soil structure and plant health by adding beneficial organic material to gardens.


Rated “Industry Best” for light and weather fastness, Black Forrest® will not leach colour when dry and its computer-monitored colour intensity stands up well to sun and frost. Aesthetically, laying Black Forrest® will make garden flowers, plants and furnishings pop dramatically, contrasted against its clean, black background.


Improve the impact and effect of your landscaping project, incorporate Black Forrest® into your design and achieve the ‘wow factor’.

Product Volume Calculator

*We will quote to the nearest cubic meter.

Recommended depths

Typically you need a finishing layer of screened soil of 100mm when working with an uneven surface. 100mm of soil will allow to even out any hollows and give enough depth to create a flat surface

A general rule for compost is to allow for the depth of the current root structure of your plants with an additional 30-50% to mix in with the base. If you’re planting into holes or filling up a vege garden  you will need to accommodate for this prior to filling up

We recommend 100mm (10cm) deep for new bark gardens and planting into bare areas. For existing gardens with some cover, we recommend 75mm-100mm (7.5cm-10cm)

Note: Barked areas for playground impact protection need to meet NZS5828:2015 standards and is calculated on the fall areas and the height of the playground. Please contact us to discuss your barked playground areas

For paths and driveways which are often exposed to car and foot traffic, we recommend 100mm-125mm (10cm-12.5cm) on newly prepared areas due to settling of product.

This excludes preparation, compaction or drainage gravel underneath. For existing areas 75mm thickness is recommended for areas needing a small top-up.
