Royal Gold® Special Reserve Premium All Purpose Potting Mix — 1.5 cu ft Bag

Pre-Charged All-Purpose Potting Mix for Vigorous Container Growth, 1.5 cu ft Bag

Building a reliable all-purpose potting mix from raw peat, coco, and amendments takes time and consistency that not every grower wants to manage batch after batch. Royal Gold's Special Reserve does that work in advance, blending coco fiber, aged forest products, peat moss, and perlite into a single substrate that's already charged with fertilizer and ready to plant into.

This 1.5 cu ft bag suits home gardeners and small-scale growers filling a handful of containers, delivering the same balanced drainage and sustained nutrition as the larger tote size in a manageable, easy-to-store package.

Key Features & Benefits

• Coco fiber, aged forest products, peat moss & perlite blend — combines moisture retention with structural drainage support for healthy root development from day one.
• Pre-charged with fertilizer — delivers immediate and sustained nutrition right out of the bag without additional amending before planting.
• Ready-to-use formula — skips the time and guesswork of building a custom all-purpose mix from raw components.
• 1.5 cu ft bag size — sized for home gardeners and small-scale growers filling a handful of containers.
• Balanced drainage and structure — supports a wide range of container plants rather than one specific crop type.

Who Should Use This

Home gardeners and commercial growers who want a ready-to-use, pre-charged potting mix for a wide range of container plants benefit from Special Reserve's built-in nutrient charge and balanced drainage structure. It suits both first-time container gardeners and experienced growers who'd rather skip building a custom mix from raw components.

About Royal Gold

Royal Gold started nearly two decades ago as a small family operation in Humboldt County, California, and has since expanded its mixing, testing, and packaging operations to Upstate South Carolina. The company markets itself as the first nationally distributed coco-fiber-based potting soil company, and Special Reserve reflects that same small-batch, quality-first approach.

Frequently Asked Questions

What is Special Reserve made from?

Special Reserve combines coco fiber, aged forest products, peat moss, and perlite into a single blended substrate. Coco fiber and peat moss hold moisture while aged forest products and perlite provide structural drainage support.

Do I need to add fertilizer before planting?

No, Special Reserve is pre-charged with fertilizer, so it delivers nutrition right out of the bag or tote without additional amending before the first planting. You'll still want to follow a regular feeding schedule as the crop grows and the initial charge is used up.

What kinds of plants is this mix suited for?

Special Reserve is formulated as an all-purpose potting mix, so it works across a wide range of container plants rather than one specific crop type. Its balanced drainage and moisture retention suit both fast- and slow-draining preferences reasonably well.

How should I store an opened bag or tote of this mix?

Keep it in a dry, covered area out of direct sun to preserve moisture content and prevent the pre-charged nutrients from breaking down prematurely. Reseal partially used bags tightly between uses.
