How to Use
- Apply granules directly into the planting hole or mix into backfill soil at transplanting.
- Place the root ball in direct contact with the treated soil so mycorrhizae can colonize immediately.
- Water in thoroughly after planting—moisture activates the fungi and drives colonization.
- For bare-root specimens, dust roots directly with granules before planting for full surface contact.
- Repeat at the start of each new growing season or whenever you add new plants.
Pro Tips
- Mycorrhizae must touch roots to colonize—place granules in direct contact with the root ball.
- Avoid high-phosphorus synthetic fertilizers at the same time—excess soluble phosphorus can suppress mycorrhizal colonization.
- Pair with a quality mulch layer to retain soil moisture and protect the fungal network.
- In compacted or depleted soils, aerate the planting zone before application to improve fungal penetration.
- Store in a cool, dry location away from direct sunlight to maintain mycorrhizal viability.
Frequently Asked Questions
What are mycorrhizae, and why do they matter?
Mycorrhizae are naturally occurring beneficial fungi that form a symbiotic relationship with plant roots, extending their effective reach by up to 700%. They dramatically improve water absorption, phosphorus uptake, and nutrient access — especially in stressed or depleted soils. The same biology used in commercial nursery and landscape production worldwide.
How is Root Booster different from a standard fertilizer?
Standard fertilizers deliver nutrients. Root Booster delivers biology plus nutrition. The Mycorrhizal fungi build a living root network that works continuously, while the 3-3-4 NPK with sulfur and iron provides the balanced nutritional foundation your plant needs at establishment — all in one application.
mycorrhizal—allHow many plants does one 8 oz. pouch treat?
At the light application rate of ¼ teaspoon per plant, one 8 oz. pouch treats up to 192 plants. The medium-to-heavy rate printed on the label delivers a more concentrated dose and treats fewer plants — recommended for larger specimens, stressed plants, or where faster establishment is the priority.
—recommendedCan I use Root Booster on established plants?
Yes. Apply as a granular top-dress or work into the soil around the drip line of established trees and shrubs to introduce Mycorrhizae into the existing root zone and reinvigorate plant health.
mycorrhizaeIs Root Booster safe for edibles and vegetables?
Yes. The formula is eco-friendly and safe for vegetables, herbs, fruit trees, and edible landscapes. Follow label directions for application rates.
How soon will I see results?
Most gardeners notice reduced wilting and faster recovery from transplant stress within 7–14 days as Mycorrhizal colonization begins. Visible new growth acceleration typically appears within 3–4 weeks as the expanded root network comes online.
mycorrhizalIs Root Booster safe around pets?
Mycorrhizae are naturally occurring soil organisms and are generally considered non-toxic. Keep pets away from treated areas until the product has been watered in and the soil has dried. Always refer to the product label and Safety Data Sheet for complete safety information.
Note: Product images represent typical specimens. Seasonal variation in size and bloom stage is normal. Plants are investments in your future garden — enjoy watching them grow.
