Who Should Use This

Royal Gold® Special Reserve is designed for container gardeners, indoor cultivation operations, greenhouse producers, and home growers who want a dependable, high-performance all-purpose potting mix that works right out of the bag. Its pre-charged nutrient profile and balanced drainage make it suitable for a wide range of flowering, fruiting, vegetable, and ornamental crops in pots, planters, fabric containers, and raised beds across indoor, greenhouse, and outdoor growing environments.

Compatibility

Works with most supplemental liquid and granular fertiliser programs. The built-in nutrient charge reduces the need for early-cycle feeding, but the mix is fully compatible with standard nutrient schedules as crops mature. Suitable for use in plastic pots, fabric grow bags, wooden planters, smart pots, and hanging baskets. The drainage and structure profile is well-matched to drip, hand-watering, and overhead irrigation systems.

Frequently Asked Questions

Does Royal Gold® Special Reserve need to be amended before use?

No. Special Reserve is formulated as a ready-to-use, pre-charged potting mix that requires no additional amendments, fertilisers, or pH adjustments before planting. Simply fill your container and transplant or seed directly into the mix for immediate results.

What crops is Royal Gold® Special Reserve best suited for?

Special Reserve’s all-purpose formulation makes it suitable for a wide range of container crops including ornamentals, herbs, vegetables, fruiting plants, flowering annuals and perennials, and tropical houseplants. Its balanced drainage and nutrient profile adapts to diverse crop requirements across indoor and outdoor growing environments.

How does the pre-charged fertiliser in Special Reserve work?

The pre-charged nutrient package is incorporated directly into the mix during production, distributing essential macro and micronutrients evenly throughout the substrate. When watered, these nutrients become available to plant roots immediately, supporting establishment without requiring the grower to apply starter fertiliser at transplanting. The charge is designed to support early growth, after which a standard supplemental nutrition program should be implemented.

How does Special Reserve compare to other Royal Gold® mixes like Planting Mix or Potting & Propagation Mix?

Special Reserve is an all-purpose potting mix that includes perlite and is pre-charged with fertiliser, making it a more complete, ready-to-use solution for general container gardening. Royal Gold® Planting Mix is perlite-free and formulated for raised beds and in-ground use, while Potting & Propagation Mix is a peat-free, finely textured medium optimised specifically for propagation and seed starting. Special Reserve sits between these as an all-rounder designed for general container production.

Is Royal Gold® Special Reserve suitable for outdoor use?

Yes. Special Reserve is suitable for indoor, greenhouse, and outdoor container growing. Its coco fiber and peat base retain moisture effectively in outdoor environments subject to variable watering frequency, and the perlite component supports drainage during periods of heavy rainfall or frequent irrigation.
