At Gammans, we believe that choosing the right potting mix really does matter – and in this article we’ll explain why. We’ve been in the industry for over 60 years, and we can tell you from experience and results that the soil makes all the difference. Over that time, we’ve perfected over 200 custom potting mix recipes for everything from roses to citrus to native plants.
Whether you’re after premium potting soil for your home garden or a tailored blend for a commercial nursery, we can create the right mix for the job.
Different Plants = Different Needs
Citrus trees, for example, are heavy feeders that demand nutrients year-round. In our blends, we use a temperature controlled release fertiliser that releases nutrients when the plants require it, giving citrus a steady feed through every season.
Roses, on the other hand, love a well drained but moist media. That’s why our rose mix is enriched with extra Hauraki peat to hold water exactly where their roots need it most.
And for acid-loving plants like azaleas and blueberries, we adjust the pH of the potting soil in a peat/bark pumice media that promotes an ideal growing environment.
Why Choose a Custom Blend Potting Soil?
A custom potting mix makes all the difference. It ensures:
- The right nutrients are available when your plants need them.
- Less waste, since nutrients aren’t lost through leaching.
- Healthier, longer-lasting plants with stronger root systems.
For example, some trees and shrubs are only active in the warmer months. In those custom blends, we include temperature controlled release fertiliser that releases nutrients in spring and summer, then slows down in winter – so you don’t end up with nutrients leaching away (and money down the drain!)
