Growing a healthy organic garden requires supplying your plants with adequate nutrients. While compost can improve the nutrient level of your garden soil, your plants will benefit from applications of a rich, homemade organic fertilizer. Your handmade fertilizer can be tweaked to help different varieties of plants and made in large batches for storage and use later on. Purchase the ingredients in bulk at your local garden store for the best deal.
Mix 3 parts seed or fish meal, 3 parts bone meal, 1 part kelp meal and 1 part dolomite lime in a large wheelbarrow.
Substitute blood meal for the seed or fish meal and add 2 parts cottonseed meal to provide extra nitrogen for leafy vegetables.
Reduce the bone meal to 1 part and add 1 part fish meal and 1 part soft phosphate for fruiting plants.
Combine the mixture thoroughly with a shovel and incorporate into the soil at planting time. Place a handful of your fertilizer mix in your transplanting hole or sprinkle it over the soil to act as a slow release fertilizer throughout the growing season.
