February Special! $5 off the 45g size. Was $19, now $14, while supplies last. Better if used by June, but still 90% effective after (see below).
Endo/Ecto - Root Rescue, a concentrated wettable powder containing nine different species each of endo- and ectomycorrhizal fungi (Glomus, Gigaspora, Paraglomus, Rhizopogon, Pisolithus, Laccaria, and Suillus; 18 species in total). Used for propagating, planting, or transplanting those woody plants that benefit from ectomycorrhizal fungi (or take both endo and ecto), such as: most conifers including hedge cedars, Douglas Fir, true fir, hemlock, larch, pine, and spruce; as well as alder, arbutus, beech, birch, chestnut, eucalyptus, filbert/hazelnut, hickory, linden, oak, pecan, poplar, and willow.
This finely powdered, dark coloured endo-ecto product is used much like the other one, and best mixed with water, except the dosage is a bit different. If the amounts of water recommended by the manufacturer seem high, this is because you should saturate the rootball and also drench the soil used for backfilling the planting hole.
How much do you need? Generally, use 4.5g (1 teaspoon) of powder in 7.5L (2 gallons, the volume of a standard watering can) of water. The 45g package makes 75 liters (20 gallons) and can treat 40 one-gallon plants or two 60mm trees, the 90g package yields 150 liters (40 gallons) of solution and can treat 80 one-gallon plants or four 60mm trees.
Applying the liquid:
How long does it keep? Store tightly sealed, dry, cool and dark. After the best before date, Root Rescue is still 90% viable for another full year if stored correctly, so just use 10% more for normal effectiveness. Mix and use only what you want to apply the same day. Diluted mixed product does not keep long.
