FAQ
The basics
What are mycorrhizae?
Mycorrhizae (say it: my-co-RYE-zee) are helpful fungi that team up with plant roots. They grow thin threads out into the soil, like an extension of the root, and reach water and nutrients the root can't reach alone.
In return, the plant shares some of the sugar it makes from sunlight. Most plants on Earth work with these fungi.
What are beneficial bacteria?
Tiny living things that are a normal part of healthy soil. They help break down organic matter and recycle nutrients into forms roots can take up.
Why so many kinds in one product?
Different plants and soils pair with different fungi, so a mix gives your plants more partners to work with.
Plant Success has 19 kinds of mycorrhizal fungi: 9 that work with most garden plants and 10 that work with trees like pines and oaks. It also has 12 kinds of beneficial bacteria.
Which plants work with mycorrhizae?
Most of them: vegetables, flowers, herbs, lawns, shrubs, fruit trees and shade trees.
A few plants use other kinds of fungi or none at all, such as the cabbage family (broccoli, kale, cabbage) and the heath family (blueberries, azaleas, rhododendrons).
Is it organic?
Yes. Both products are OMRI Listed for organic use. The certificates are linked on each product page.
Using it
Granular or Soluble: which do I need?
Granular goes in at planting time, right next to the roots, and includes an organic 3-1-2 plant food.
Soluble mixes with water for plants that are already growing, including pots and houseplants. Plenty of gardeners use Granular when they plant and Soluble after that.
How do I use it?
The fungi have to touch the roots to team up with them.
- Granular: sprinkle it in the planting hole, right where the roots will sit, then plant and water.
- Soluble: mix 1 teaspoon per gallon of water and pour it at the base of the plant so it soaks down to the roots.
The label and each product page show how much to use.
When should I use it?
As early in the plant's life as you can. Planting or transplanting is the best time. Soluble can go on any time of year.
Does it work on trees?
Yes. Plant Success has both kinds of mycorrhizae that trees use: 10 kinds for trees like pines, oaks and birch, and 9 kinds for fruit trees, maples and shrubs.
Use Granular in the hole when you plant a tree, or water in Soluble around trees already in the ground.
Does it work on houseplants?
Yes. Mix Soluble with water and pour it on the soil, or add Granular to the new pot when you repot.
Can I use too much?
You don't need more than the label rate. The rates are set so a little goes a long way.
Do I need to feed the microbes?
Organic matter helps. Compost, kelp, fish and humic products give soil life something to eat. Granular already includes organic plant food, and Soluble includes seaweed extract and humic acids.
