In order to produce a fruitful and organic vegetable garden, you need to use organic fertilizers. These materials will help your vegetable plants as well as your household plants mature gracefully without those harmful chemicals.

Organic fertilizers should be made of natural decomposition, because these materials are easier for the plant to digest. As you will see from the list below, organic fertilizers are simple and natural ingredients. However, they contain essential macro- and micronutrients such as nitrogen, calcium, phosphorus, potassium, magnesium, iron, organic matter and trace minerals.

Here are some organic fertilizers that you might want to try:

  • Alfalfa meal
  • Bat and bird guano
  • Bloodmeal
  • Bonemeal
  • Chicken manure
  • Cottonseed meal
  • Epsom salts
  • Feather meal
  • Fish emulsion
  • Fish meal
  • Greensand
  • Humic acids
  • Kelp meal
  • Oyster shells
  • Seaweed (liquid)
  • Soft Rock Phosphate
  • Worm castings/Vermicompost

When you’re reading the labels on fertilizers, look for the basic elements that you learned from the periodic table. For example, avoid super triple phosphate, because this is a manmade form of phosphorous. If you’re not sure where to start, begin with the basics. Liquid seaweed is a supplement that provides trace elements. Also, adding humic acid can improve the soil health. Another option is organic root biostimulants, which can sometimes contain seaweed, humic acids and vitamin B1. Although this is a short list of ingredients, they all help with soil fertility, root development and healthy foliage.

Humic acid also makes a great addition to a compost tea. In order to create the tea, mix a gallon of compost with three gallons of water. After it sits for one night, a brown tea or liquid will form on the top. Scoop this out and use it on your plants as a fertilizer. If you have new or shell-shocked plants, make sure to strain the tea before application and use a good spray of seaweed.

These fertilizers are great for indoor and outdoor plants. However, you might not want to use the manures indoors due to the odor. Now that the season is changing, your focus might be directed toward your houseplants, and it’s beneficial to keep these thriving so you have color in your home as well as a natural air purifier.
