When it comes to growing healthy plants – whether you’re running a nursery, landscaping a subdivision, or planting out a motorway, success always starts with the soil. At Gammans, we specialise in bulk potting mix, bulk compost delivery, and custom potting mix blends. They’re made onsite, right here in Tauranga, and we’ve been doing so for over 50yrs!
Across New Zealand, demand for large-scale planting is growing. It’s about soil stabilisation, protecting waterways, preventing erosion, and boosting biodiversity. Projects like this, highlight how vital the right soil and mulch are, and why reliable bulk buy compost and potting mix suppliers are essential.
Supplying Commercial Nurseries and Big Landscapes
For commercial nurseries, consistency is everything. Our custom potting mixes are tailored to suit plant needs at every stage, ensuring strong growth and reliable results. Being able to order bulk potting mix directly from us saves time and money while guaranteeing a steady supply year-round.
On the larger scale, landscape companies, developers, and councils rely on bulk compost delivery and mulch to meet planting and rehabilitation requirements. From soil stabilisation on highways such as the Takitimu North Link, to regeneration projects and backyard landscaping jobs, having access to locally blended mixes ensures both quality and cost-effectiveness.

Why Natives Need a Different Approach
Native plants don’t thrive in overly rich soils. They’re not heavy feeders, so a specialised long term native potting mix is not only better for the plants but also more cost-effective for big projects.
Combined with mulch, a native-specific potting mix supports healthy roots, retains moisture, and helps ensure survival rates long after planting. For landscapers and contractors, choosing the right bulk buy compost and soil blend can mean long-term savings and stronger results.
