Organic gardening is really fun because you can produce delicious veggies naturally right from your garden. The most common source of organic matter is compost. But there are times that you can't make your own compost and there are times when you don't have enough organic matter to fertilize your garden. There are liquid fertilizers available in garden stores. These can be a substitute to regular application of compost, but organic liquid fertilizer is quite expensive, especially if you have plenty of plants to fertilize.


  1. Example: 1 kg. plant materials, 1 kg. brown sugar, 1 gallon (3.8 L) water. This can be reduced, just remember the ratio.
  2. Mix the materials together until the sugar is dissolved in water.

  4. Make sure the container won't be disturbed.[2]
  5. Do not disturb or move it as much as possible.[3]
    • A week later, you will notice molds growing on the surface. The liquid will have a sweet-sour smell. It may be disturbing but its worth it. It is a sign that beneficial bacteria has inhabited the liquid.
  6. Leave enough space for the bacteria to breathe. The solid materials can be placed into the compost pile, if you have. Otherwise, throw it in the trash.[4]

  8. Mix 1 cup of the liquid to 1 gallon (3.8 L) of chemical-free water. It is best applied early in the morning or late afternoon. Use the diluted liquid to water the plants at their bases.
    • For most plants, apply the diluted FPJ at least once a week.

  • Question
    Can I use white sugar? And what are plant materials?
    Top Answerer
    You can use white sugar, but brown or crude sugar is better because it gives elements to bacteria that help them to grow. Concerning the plants, you must use Nitrogen-rich parts like stems and leaves of pea, bean, lentil, soya or peanuts.

    Light, air, and heat are the enemy of nutrients. Store your juice in a cold dark area in an airtight container.

    You can, but it won't give you the same osmotic pressure as granular sugar.
