Clear the soil's surface of leaves, twigs and debris in your existing vegetable or flower beds. Pull any weeds and loosen the surface of the soil using a rake.
Spread Ultragreen 15-30-15 fertilizer at a rate of 1 1/3 cups per 50 square feet evenly over the soil of your vegetable garden or flower beds. Spread the fertilizer in a wide band around trees or shrubs, keeping it at least 6 inches away from their trunks or stems. Position the ring of fertilizer under the outer edges of their canopies.
Mix the fertilizer into the soil with a rake or shovel to a depth of 4 to 6 inches. Water the area thoroughly with a garden hose to activate the fertilizer.
Add 1 1/2 teaspoons of Ultragreen to the bottom of the hole when transplanting annuals or perennial bedding plants, bulbs or roses. Mix the fertilizer into the soil. Add 1 inch of soil into the hole over the fertilizer before setting the plant's roots inside. Bury the plant's roots or bulb in the hole and water around it thoroughly with a watering can.
