Premier PRO-MIX Premium Potting Mix with MYCOACTIVE | 16qt - Loose Fill

Slow-Release Fertilizer Potting Mix with Water-Saving Gel, 16qt

Container plants that get fed and watered on a fixed schedule can still struggle if the potting mix itself dries out fast or runs out of nutrition between feedings. Premier PRO-MIX Premium Potting Mix with MYCOACTIVE is built around a water-saving gel that holds extra moisture between waterings and a slow-release fertilizer that feeds for up to nine months, blended with Canadian sphagnum peat moss, perlite, limestone, and Mycorrhizae from Premier Tech.

This 16qt loose fill bag is a mid-size format for growers potting and repotting a moderate number of containers without buying a full 1cu ft or 2cu ft bag.

About Premier PRO-MIX

PRO-MIX comes from Premier Tech, which has sold peat substrate since 1923 and introduced the PRO-MIX brand in 1968. Premium Potting Mix draws on the company's own peat supply and its biotechnology lab, which produces the mycorrhizal inoculant blended into the formula.

Frequently Asked Questions

What is this mix used for?

It's built for seed starting as well as potting and repotting plants in containers. The slow-release fertilizer and water-saving gel are formulated for that container-growing use case rather than in-ground planting.

How long does the fertilizer last?

It contains a slow-release fertilizer that feeds for up to nine months from potting, which reduces how often a separate feeding schedule is needed. Growers with plants staying in containers longer than that should plan to resume feeding after the nine-month window.

What does the water-saving gel do?

The gel holds extra water within the mix so containers dry out more slowly between waterings. That adds a buffer for growers who can't water on a strict schedule, though it doesn't replace regular watering entirely.

Does it include mycorrhizae?

Yes, Mycorrhizae from Premier Tech is blended into the mix to support root development as the plant establishes. No separate inoculation step is needed at potting.

What sizes does this mix come in?

It's available in multiple package sizes, including 1cu ft and 2cu ft loose fill bags and a 16qt bag. Growers can match the size to a single container or a full potting run.
