Organic Fertilizer Instructions


Using organic fertilizer is a safe, easy and inexpensive way to reap the benefits of gardening. While flowers, fruits and vegetables require varying ratios of nutrients, the needs of each can successfully be met when organic fertilizer is applied properly. Organic fertilizer, compost and mulch can also eliminate the need for multiple commercial fertilizers with unique nutrient ratios. Remember that organic fertilizer is typically slow release and results are achieved over time and are more abundant than chemically prepared, rapid-release fertilizers.

Step 1

Determine the size of your garden area. Measure the width of the garden in feet and record on paper. Then measure the length of the same area. Multiply the width by the length using a calculator or pencil and paper. This will give you the square footage of your garden. A garden measuring 20 feet wide by 40 feet long equals 800 square feet of garden space.

Step 2

Purchase organic fertilizer from a garden supply store. Organic fertilizers are slow-release fertilizers available in varying ratios of nitrogen, phosphorus and potassium. Obtain one that will meet the nutrient needs of your soil. If you're not sure what those needs are, perform a simple soil sample pH test, also available at stores that sell garden supplies.

Step 3

Apply 1.5 gallons organic fertilizer uniformly over each 100 square feet of garden area prior to planting crops. Record each organic fertilizer application on a calendar for quick, easy reference.

Step 4

Using your hand, sprinkle organic fertilizer around plants one to two weeks after growth appears. Once again, record the application on the calendar.

Step 5

Re-apply organic fertilizer every three or four weeks for flowers, fruits and vegetables requiring high levels of fertilizer by sprinkling around each plant.

Step 6

Use your calendar to track growth and fertilizing dates. This will save from over-using fertilizer and help document growing progress.
