Homemade fertilizers for Eggplant 

Neem Cake

It also acts as a bio-fertilizer by providing the required nutrients, nitrogen, and phosphorus required for the growth of Eggplant. Its use ensures higher crop production.

Wood ash

Wood ash is an easily available source of potassium, calcium, and magnesium which is essential for plant health. Take 1/2 kg vermicompost, 1/2 kg neem cake, 1/2 kg wood ash, 1/2 kg cattle compost all in a bowl and mix everything well.

Liquid fertilizers for Eggplant  

  • Manure tea Cow manure influences the number of fruits per plant, length of fruits, the diameter of fruits, and weight of fruits per plant. When you add cow manure to the growing area of your Eggplant, it helps the plant by holding water to the soil needed by the plants, and it also gives the soil a good structure, resulting in light, bloated soil that is not compacted. Heavy soil can benefit a lot when you add cow manure. Eggplants need well-drained soil that is full of nutrients, and that’s what cow manure provides.
  • When the first flower appears, spray the plants with a seaweed extract, with a teaspoon of Epsom salt per gallon dissolved. This solution improves the fruit set.

Commercial fertilizers for Eggplant 

Fertilizers can be chemically produced or come from natural sources such as plant matter, animal fertilizer, or minerals found in rock. Powder, palette, or granules can be applied between rows or as side-dressing in soil based on Eggplant. Fertilizers applied in this way should work in the dirt to prevent heavy rain from spraying fertilizer on the plant.  Since plants can absorb nutrients through their leaves, foliar feeding is an alternative way to the Eggplant. 

Use commercial liquid fertilizer designed for foliar feeding or make your own with thin manure tea. Apply this liquid as a fine spray, early in the morning when the temperature around is cool. Finally, gardeners cannot go wrong when choosing quality tomato manure when there is doubt about composting the Eggplant. Like tomatoes, Eggplants are members of the nightshade family and have similar nutritional needs.

NPK ratio 

Although Eggplant is a relatively simple plant to grow, they are heavy feeders. The plant can be improved with the addition of fertilizer. Before planting outside, add 2 to 3 inches of well rotten manure in the soil. If manure is not available, select 10-10-10 fertilizer instead. Once the fruit starts appearing on the Eggplant, you can use 10-20-20 fertilizer or 10-30-10 fertilizer. 

Eggplant fertilizer schedule

  • Mix manure or 10-10-10 fertilizer in the ground at least 6 inches to provide increasing fertilization to the roots of the Eggplants.
  • Mix manure or fertilizer with a shovel in soil. As much as possible, work together to 6 inches deep or more so that the feed is available as the Eggplant roots are long. Plant  Eggplant seeds or transplant seeding into the ground.
  • Look at the Eggplant first to make flowers and wait for the shape of the growing little fruit. Spread around plants a circle of 6 to 8 inches wide 10-20-20 or 10-30-10 manure, called side-dressing, using a total of 450 to 680 grams for a 100-square-foot area. Add feed at a depth of 3 to 4 inches. When you mix fertilizer, be careful not to dig too close to the Eggplant otherwise you will disturb or rip the roots.
  • Harvest your first crop of Eggplant and reapply 10-20-20 or 10-30-10 fertilizer side dressing. Since Eggplant production will continue, more fertilizer uses can be added every two weeks if desired.

How to fertilize Eggplant in pots 

When it comes to fertilizers in pots, Eggplant plants are heavy feeders and need the right amount of fertilizer. Prepare a soil mixture with 1/4 compost and equally rotten cow manure or chicken manure. Add this fertilizer during the growing season as well. Eggplants are heavy feeders, but avoid adding high levels of nitrogen fertilizer as this will result in more green leaves than fruit. Once the first one starts to bloom on the plant, you can fertilize the plants with liquid fertilizers. There are great liquid fertilizer options to choose from seaweed, fish emulations.
