Making your own organic fertilizer is inexpensive and simple. You can purchase bulk components and mix them or gather the necessary components from around your home. Fertilizers should contain macro nutrients such as nitrogen, phosphorous and potassium. Micro nutrients should include sulfur, copper, selenium and magnesium. Individual components are mixed together in specific ratios so that all nutrients are balanced. Certain plants require higher ratios of nutrients than others. You can make your own organic fertilizer specifically for these plants.
Make your own organic fertilizer from purchased bulk components
Purchase seed meal, dolomite lime, bone meal, kelp and Epsom salt in bulk quantities. All the ingredients can be purchased through your local garden center.
Use a large scoop to measure quantities of the components. The ratio by volume is four parts (scoops) seed meal, one part dolomite lime, one part Epsom salt, one quarter part bone meal, one quarter part kelp meal. Put components into the bucket.
Put on rubber gloves and mix components together thoroughly. Store unused components in a cool, dry place. Close the bucket tightly with a lid.
Make your own organic fertilizer from common items
Place ground egg shells, coffee grounds, grass clippings, newspaper, leaves, kitchen scraps and rabbit manure into a worm compost bin as worm food.
Collect worm casings. Mix three parts worm casings with one part Epsom salt into large bucket.
Store the bucket in a cool, dry place when not using. Continue to add worm casing, Epsom salt mixture to the bucket.
The worm casing Epsom salt mixture can be liquefied before using. Fish emulsion also works well as a liquefied fertilizer.
