MYCOACTIVE®: Growth Enhancer

MycoActive® is MYCORRHIZAE™ PREMIER TECH, a natural biological plant stimulant. Microscopic organisms attach to plant roots and form an extensive secondary network that dramatically increases the root system's reach. This allows plants to absorb more water and nutrients from the soil, leading to stronger, healthier growth.

Only MycoActive® delivers the combination of an Organic Growth Enhancer with precisely selected ingredients, giving plants an all-natural boost while increasing their resistance to environmental stresses such as drought and temperature extremes.

More Vegetables, Stronger Roots, Bigger Blooms

🌿

Doubles Yield

MycoActive® extends the root network, enabling plants to take in more nutrients and water — resulting in significantly higher yields for vegetables, herbs, and flowering plants.

💧

Stress Resistance

Plants fortified with MycoActive® are better equipped to survive extreme conditions, including drought and heat, reducing the need for constant maintenance.

🌸

Vibrant Blooms

Expect more luscious, vibrant, and healthier flowers. The organic growth enhancer supports robust blooming and richer foliage across all plant types.

How It Works

MycoActive® contains beneficial mycorrhizal fungi that colonize plant roots. Once established, these microscopic organisms form a vast filament network that acts like a secondary root system, reaching far beyond what the plant's own roots could access alone.

This symbiotic relationship means plants draw in more water and dissolved nutrients while the fungi receive carbohydrates from the plant. The result is a natural, self-sustaining growth partnership.

Every Pro-Mix growing mix contains MycoActive®, so you get this benefit automatically — no extra steps required.

Built Into Every Bag

You don't need to add anything extra. All Pro-Mix growing media — from Potting Mix and Garden Mix to specialty blends like Orchid Mix and Cactus Mix — are formulated with MycoActive®. Whether you're starting seeds, repotting houseplants, or planting a vegetable garden, your plants get the growth-enhancing advantage from day one.

MycoActive represents a breakthrough in natural plant care, harnessing the power of beneficial microorganisms that form a symbiotic relationship with plant roots. These microscopic organisms attach themselves to the root system and create an extensive secondary network underground, dramatically expanding the area from which plants can draw water and essential nutrients. This biological process mimics what happens in nature's most fertile soils, where thriving plant communities depend on these underground partnerships. For gardeners who want to reduce their reliance on synthetic inputs while still achieving vigorous growth, MycoActive offers a science-backed approach that works with the plant's own biology rather than overriding it.

The benefits of MycoActive extend far beyond simple nutrition. By increasing the root system's effective reach, plants become more resilient against common environmental stresses such as drought, temperature fluctuations, and transplant shock. When roots can access moisture and nutrients from a larger volume of soil, plants are better equipped to withstand periods of dry weather without wilting or suffering permanent damage. This natural stress tolerance means less hands-on intervention from the gardener and more consistent results across changing conditions. Whether you are growing vegetables in raised beds or tending container plants on a patio, the enhanced root development leads to sturdier stems and more abundant blooms.

MycoActive is particularly valuable for organic gardeners who want to maximize the potential of their soil without using chemical stimulants. As an OMRI-listed product, it meets the rigorous standards required for certified organic production, giving growers confidence that they are making an environmentally responsible choice. The carefully selected ingredients work in harmony with compost, aged manure, and other organic amendments commonly used in sustainable gardening. By improving the efficiency of nutrient uptake, MycoActive helps reduce fertilizer runoff and ensures that the amendments you apply go further, feeding both the plant and the beneficial soil life that supports long-term garden health.

Integrating MycoActive into your regular gardening routine is straightforward and rewarding. Simply apply it to the root zone at planting time or mix it into your potting medium for container gardens, and the microorganisms will begin colonizing the roots within days. For established plants, it can be worked gently into the soil around the base or applied as a drench during regular watering. The effects compound over time as the fungal network expands season after season, creating a living infrastructure beneath your garden that continuously supports plant health. Gardeners who use MycoActive often notice improved vigor in their vegetables, herbs, and flowers, with plants that are more productive and better able to handle the challenges of the growing season.
