Homemade Organic Fertilizer


Applying fertilizer to the lawn or garden is essential to good growth. As plants grow, they use up nutrients that exist in the soil. As nutrients are depleted from the soil, the plants begin to weaken. An application of fertilizer replenishes the soil and aids growth and healthy development of the plant. Making your own organic fertilizer at home is less expensive than buying brand-name fertilizer and ensures you know what you are putting into your garden.

Step 1

Buy seed meal from a local farm and ranch store. This is the easiest place to find seed meal, as it is used to feed livestock, says Steve Solomon at Mother Earth News. Most local garden centers should carry the rest of the ingredients. Check the seed meal packaging to ensure the meal comes from an organic source.

Step 2

Mix four parts seed meal, one-quarter part agricultural lime, one-quarter part gypsum and one-half part dolomitic lime in a large plastic bucket. Add 1 part bone meal, and one-half part to one part kelp meal to the mixture for added fertilizer power, according to motherearthnews.com. Use the same scoop for all of the different components, with one scoop acting as one part, half a scoop as one-half part, and so on. Bone meal provides phosphorous to the soil, while gypsum and lime control soil alkalinity, balancing the pH and improving the soil structure.

Step 3

Apply the fertilizer once a year, usually in the spring for best results. Apply 4 to 6 quarts of fertilizer per 100 square feet of space, suggests Solomon. Sprinkle small amounts of fertilizer around high-demand plants every three to four weeks.
