Uses & Applications:

New Garden Bed Preparation : Apply Suståne to the soil prior to tilling or incorporate into the top four inches of soil.
Vegetable Row Crops : Apply Suståne directly in the row with the seed when planting.
Transplants and Established Plants : Apply Suståne into the hole prior to planting transplants or around the base of the plant for established plants.
Soil Mixes & Potted Plants : Incorporate Suståne into the potting mix before plating or transplanting.
Trees and Shrubs : For new planting, place Suståne in hole before planting and lightly incorporate. For established trees and shrubs, broadcast Suståne at the base of the plant in the spring and again in the fall. Application rates are based on the individual plants canopy spread along with the fertilizer analysis.
Turfgrass Establishment (Seed) : Broadcast Suståne with the grass seed when plating.
Turfgrass Establishment (Sod) : Broadcast Suståne prior to laying sod. Lightly incorporate into the top 2 - 4" of soil. Reapply fertilizer 30 - 45 days after laying sod.
For best results, apply water after application. Application rates vary based on soil conditions, plant species and desired rate of growth. It is recommended to have soil tested prior to applying any fertilizers.
