SUPERspore Root Dip

SUPERspore Root Dip combines our Super Gel product with endo and ecto mycorrhizae fungi. The mycorrhizae fungi colonize within the root system, and greatly increase the plant's ability to absorb water and nutrients. Higher survival rates and faster establishment in SUPERspore dipped plants is typical. 


SUPERspore Root Dip

SUPERspore is technology to the rescue. This combination of endo and ecto mycorhizal fungi and Super Gel naturally increases nutrient and water uptake. SUPERspore improves seedling and transplant survival rates. Fungi will last the life of the tree or shrub, making them drought resistant and more adaptable to tough growing situations. 3 ounces will treat approximately 100 seedlings or 50 transplants and 15 ounces will treat approximately 500 seedlings or 250 transplants.

Instructions: Mix contents of 3 oz. package with 1 gallon of water, or contents of 15 oz. package with 4-5 gallons of water and let stand for at least 5 minutes. Dip the roots into the solution and let them soak for at least 20-30 minutes (maximum of 4-6 hours). Allow the product to drain very briefly and plant your bare root plants. 

Note: When mixing the SUPERspore in water, make sure the product is poured slowly and the water is moving. The longer it is allowed to stand, the tackier it will become. It is not advisable to pour the solution down a drain.

Product Questions

Would this be helpful to use on the white pine forestry plugs?
Question by: Chris Cejka on Oct 29, 2020, 12:09 AM
The use of the SuperSpore root dip would not be recommended for the forestry plugs. You mix the root dip with water and dip bare roots in the solution before planting. If you did this you would wash off the soil off the plugs.

Once the SuperSpore is mixed, can it be reused for a second batch of shrubs or trees? Also, how does one dispose of leftover "slurry," if you recommend not pouring down drain or adding to planting hole.
Question by: Alice on May 9, 2021, 11:33 AM
SuperGel can be reused, just make sure to mix it or add some additional water. To dispose of it you can simply pour it out in your yard. It is not harmful to the outdoors.

Do you recommend using this product in combination with a starter fertilizer (such as BioTone) when planting bare-root trees, or does it render the fertilizer unnecessary/excessive?
Question by: Benjamin on Nov 25, 2021, 5:47 PM
When planting bare-root trees, fertilizer should not be used for the duration of the full planting year. Once the seedlings are into the spring of their second year, you may use fertilizer.

If I already have extremely healthy soil conditions, would it be beneficial to add the SuperSpore mycorrhizal fungi? I'm planting fruit trees/shrubs into an existing meadow that is flourishing.
Question by: Derek on Mar 10, 2022, 9:30 AM
The ecto and endo mycorrhizal fungi form a symbiotic relationship with the roots. It lasts for the lifetime of the tree, encouraging moisture retention.
Answer by: Chief River Nursery on Mar 10, 2022, 10:36 AM
I would like to purchase the superspore product but not sure on amount.
Can it be used with potted seedings/dirt bound small plants or only bare rooted products. How about vegetable seedlings? If yes then how to use?
Question by: Peter Pantano on Mar 19, 2022, 11:58 AM
You can use them in new plantings, but you need to make sure that the roots and soil make contact with the product. The ecto and endo mycorrhizal fungi form a symbiotic relationship with the roots. It is meant to be used to make root contact and soil contact. It could be added to the planting hole when planting in both open soil and containers, ensure the roots of the plant come into contact with rootgrow, backfill and water as normal. What ratio to use in the planting in the hole, I don't have information on since we use it as a root dip. I would suggest using a very minimal amount in the hole.

It can get a little complicated as to what plants to use the different ecto and endo mycorhizal fungi on. Super spore contains both ecto and endo fungi. Plants that do not respond to endo mycorrhizae include azalea, beet, blueberry, broccoli, Brussels sprouts, cabbage/kale, carnation, cauliflower, collards, cranberry, heath, huckleberry, mustard, protea, rhododendron, sedge and spinach. Most trees and shrubs like the ecto fungi.
