SuperThrive claims to enhance plant growth and vigor. This concentrated, nontoxic liquid multivitamin solution for trees and garden plants isn’t a standard pesticide, so it can be used in addition to your usual fertilizer. SuperThrive was designed in 1939 and has sold continuously since then. For trees, it is advertised as a treatment for transplant shock when trees have been moved to a different place and also a tree health tonic.
Mix SuperThrive focus at a rate of 1 tsp of concentrate per gallon of water for transplanting bare-root trees. Set the tree in the planting hole and fill the hole using the SuperThrive solution. Soak the roots for 15 minutes or until the water stops bubbling, whichever comes last, then fill in the planting hole with soil. Water well with more SuperThrive solution. Do not water again for 24 hours. If your tree includes a wrapped root ball, then go to Step 2.
Set the wrapped root ball of the tree into a solution of 6 teaspoons SuperThrive to 5 gallons of water in a bucket until the ball is well nourished. Move the moist root ball into the planting hole. Remove wrapping if necessary and fill in the hole with soil. Water well with more SuperThrive solution. Do not water again for 24 hours. If yours is an already-established tree, go to Step 3.
Feed established trees using SuperThrive weekly to monthly. Feed trees throughout the origins using a SuperThrive solution made up of 1 teaspoon of SuperThrive per gallon of water. Mix enough solution to guarantee the soil around the tree is well-watered. Use the solution the exact same day you mix it. Supplement groundwater feeding using foliar feeding, which can be feeding trees during their leaves. For foliar feeding, mixture SuperThrive at a rate of 3 ounces per 100 gallons of water. Using a garden sprayer, spray the solution on the tops and undersides of the leaves, wetting them thoroughly.
