Recipe for Growing Beautiful Flowers

Compost tea is a multipurpose liquid fertilizer and is not only suitable for flowering plants but all plants and vegetables in general. Besides providing nutrients, compost tea has other benefits as well. The study published in NIH proves the positive effects of compost tea on plants.

You’ll Need

  • Bucket (5 Gallons Capacity)
  • Quality Compost
  • Aerator pump
  • Filter Cloth

Step 1: Place the aerator pump at the bottom of the bucket. Fill the bucket one third to half with quality compost. Ensure that compost is well-aged and free from any pathogens.

Step 2: Fill the bucket with water but not up to the brim. Leave 3-5 inches of space to provide some stirring room.

Step 3: Add an ounce of molasses to this mix. It will act as food for bacteria, which are beneficial for the soil. Check that molasses should be free from any sulfur content.

Step 4: Mix all the ingredients using a spatula. Continue stirring till you obtain a uniform paste.

Step 5: Switch on the pump as it will aerate the compost tea by providing a continuous flow of oxygen and circulation while the tea brews. Make sure that the pump is powerful enough to move the tea.

Step 6: Let the tea brew for 2-3 days. Stir occasionally around one or two times a day. It is to ensure that no material is left sitting at the bottom during brewing.

Step 7: The Compost tea will be ready within three days. Turn off the pump when tea starts to give a sweet and earthy smell. Strain into another bucket using a filter like a muslin cloth, burlap sack, or cheesecloth.

Step 8: Your compost tea is ready for use. As it starts to lose its potency with time, it is better to use it as soon as possible. It will not be of much use after three days.

You can apply it directly to the soil or use it as a foliar spray. The choice is yours!


  • It helps in the suppression of foliar diseases when you use it as a foliar spray.
  • Plants absorb the nutrients quickly via roots as it is a liquid fertilizer.
  • Immunity against diseases is developed because of beneficial microorganisms.
  • The productivity of plants increases, i.e., better-tasting vegetables, bigger flowers, and greener leaves.

Now put this tray in the oven while cooking something else owing to the fact that it will save electricity.

Let the leaves cool off and crush them manually, or you can obtain a powdered form by using a blender. Sprinkle the dehydrated banana peels around the houseplants or use it for side dressing your plants.

Add one tablespoon of powdered banana peel to the planting hole. Make sure to add a layer of soil over it before planting.


  • Banana peels are about 42% potassium. The movement of nutrients and water between plant cells is enhanced because of the high potassium content.
  • It also discourages floppy growth in plants by strengthening the stems.

5. Fish Emulsion

Recipe for Growing Beautiful Flowers 5

Treating garden soil with fish emulsion might feel like a bizarre way to boost blooms, but it is not! It has been around for a while and is a great alternative to harmful chemical fertilizers. Moreover, the NPK ratio of fish emulsion is 4:1:1, which makes it great for plants with a nitrogen deficiency. It is one of the best Recipes for Growing Beautiful Vegetables and Flowers.

You’ll Need

  • Fish Scraps or Whole Fish

  • Molasses
  • Organic Matter
  • Water

Step 1: Collect fish scraps and put them in a bucket up to one-third of its height. You can also use a whole tilapia fish.

Step 2: Add organic matter like sawdust or leaf litter to the bucket in equal parts to that of fish scraps.

Step 3: Add molasses to this mix, as it provides a food source to the helpful bacteria, which are beneficial for the soil. Use unsulfured molasses for this.

Step 4: Fill the remaining space available in the bucket with water. Cover the bucket and keep it in a shady spot.

Step 5: Stir the contents of the bucket 2-3 times a week. Strain the contents into another container after a week. The solution obtained is called the fish emulsion.

Step 6: Before using the fish emulsion, dilute it by adding a gallon of water to one cup of fish emulsion. Apply this directly to the soil or on the foliage of plants.

For a more nutrient-rich solution, you can also add seaweed with organic matter.


  • The NPK ratio of fish emulsion ranges from 5:2:2 to 5:1:1, which is pretty high considering it’s homemade.
  • It uses parts of the fish, which you would have dumped in the trash otherwise.
  • It is an all-purpose fertilizer and can be used for fruiting, flowering, or showy plants.

6. Seaweed Fertilizer

Seaweed is used to prepare a liquid fertilizer rich in trace elements that are absent from most fertilizers. Kelp is the most commonly used seaweed, although other seaweeds can also be used.
