How to Make Simple Liquid Organic Fertilizer for Vegetable Gardens


Most vegetables require high soil fertility in order to produce an abundant harvest. Organic fertilizers may be expensive or hard to find, so creating your own liquid solution can be both a money and a time saver. Vegetables require nitrogen, phosphorus and potassium for healthy growth. The nitrogen encourages foliage development, while phosphorus aids in flowering. Potassium and other trace minerals encourage overall plant health. Homemade organic fertilizer solutions must provide all these required nutrients.

Step 1

Fill a burlap sack with aged manure from an herbivore or with fish guts and discarded parts. Place the sack in a bucket, and add two parts water to one part manure or fish parts. Leave the manure or fish to steep in the water for one to two weeks.

Step 2

Remove the burlap sack from the water, and use the remaining liquid for fertilizing. Combine the liquid with equal parts water.

Step 3

Add 3 lbs. animal bone ash and 5 lbs. wood ash to every 3 gallons of the manure or fish liquid. Stir to combine.

Step 4

Apply 3 to 4 gallons of the liquid fertilizer per every 100 square feet of bed. Stir often while fertilizing, as the ash tends to settle to the bottom of the solution. Alternately, water container grown vegetables every two weeks with the fertilizer solution.

Tips and Warnings

  • Uncomposted manure may burn vegetables. Use only manure that is already composted.
