Step-by-Step Guide: Applying Organic Fertilizer

Applying organic fertilizer correctly ensures effective nutrient delivery to your plants. Follow these steps for optimal results:

Granular Fertilizer Application

1. Determine the appropriate amount based on the product instructions and your soil test results.
2. Evenly distribute the fertilizer around the base of the plants, avoiding direct contact with stems.
3. Gently work the fertilizer into the top layer of soil.
4. Water thoroughly to help activate the nutrients.

Liquid Fertilizer Application

1. Mix the liquid fertilizer with water according to the manufacturer’s instructions.
2. Apply the solution directly to the soil around the plants.
3. Water the plants lightly afterward to prevent any potential burns.

Slow-Release Fertilizer Application

1. Follow the recommended dosage on the product label.
2. Spread the fertilizer evenly around the plants.
3. Water the area to initiate the slow release of nutrients.
