DIY Bloom Boosting Fertilizer Recipes

Bloom booster fertilizers are special mixes made to help plants produce more flowers. They usually have more phosphorus and potassium but less nitrogen to make sure plants get everything they need but focus on flowers instead of too many leaves.

1. Mustard Cake

Typically, mustard cake has about a 4-1.5-1 (N-P-K) ratio, making it an excellent source of nitrogen, which encourages the production of flowers. It is also great for preventing bud drop, which is a common problem faced by many gardeners.

However, moderation is the key, as too much of it can promote vegetative growth. To use it, submerge the cake in a bucket of water overnight. The next morning, dilute the solution with water in a 1:1 ratio and use it once in 6-8 weeks to water the plant.

2. Hair Clippings as a Flower Bloom Fertilizer

Hair Clippings as a Flower Bloom Fertilizer


  • Human or dog hair clippings

Preparing Process

  • Cut the hair into small pieces to mix easily into the soil. Blend the chopped hair evenly into the soil around your plants.
  • Ideal during the growing season for healthy foliage. Once every 6-8 weeks as hair releases nutrients slowly.

Benefits & Precautions

Hair clippings provide nitrogen, crucial for lush foliage and vibrant blooms. Ensure hair is free from chemicals, dyes, or treatments. Excess nitrogen can harm plant growth and the environment.

3. Fermented Fruit Juice (FFJ) Fertilizer

Fermented Fruit Juice as fertilizer


  • Apples, Strawberries, Raspberries (Or 3 fruits rich in phosphorous and potassium).
  • Equal weight of brown sugar.


  • Chop fruits into small cubes and add 4-5 teaspoons of sugar.
  • Place the solution in a container, leaving space for fermentation.
  • Cover with breathable material and store in a dark, dry area.
  • Allow fermenting for 5-10 days, depending on temperature.
  • Once fermentation completes, strain to collect the liquid.
  • Dilute FFJ in water at a 1:3 ratio. Apply as a foliar spray or soil drench weekly during flowering.

For added benefits, mix with other fertilizers at lower concentrations. Combine with equal parts vinegar to adjust acidity.


  • FFJ is cost-effective and natural.
  • It enriches plants with vital nutrients and beneficial microbes.
  • Enhances flower quantity and quality.


  • Avoid high concentrations to prevent plant damage.
  • Apply during cooler times of the day.

4. Fertilizer with Grass Clippings

Turn grass clippings into a powerful, eco-friendly fertilizer to enhance your garden’s flower blooms.


  • Grass clippings


Gather clippings after mowing your lawn. Make sure they are free from chemicals or pesticides. Spread them out to dry for a day or two, reducing moisture and preventing mold. Once dry, chop the clippings into smaller pieces for better decomposition and nutrient release.

Apply in spring or early summer during active flower growth. Spread a 2-3 inch layer around your flowers. It retains moisture and suppresses weeds. Mix clippings into the top 4-6 inches of soil around your flowers.


Supplies essential nitrogen, potassium, and phosphorus. Reduces weed growth for less competition. Keeps soil moist, cutting down on watering needs. A great way to recycle and reduce chemical fertilizer use.


Don’t use clippings from lawns treated with herbicides. Too much can hinder soil aeration and create odor. Ensure the mulch isn’t too compacted to allow water through.

5. DIY Gelatin Powder Flower Fertilizer

gelatin powder fertilizer



Combine 1 tablespoon of gelatin powder (unflavored) with 2 cups of water. This ratio ensures an ideal concentration. Stir the mixture until the gelatin powder fully dissolves. This step is crucial for making the nutrients available to your plants.

Use this mixture during your flowers’ growing season for optimal results. Gently water your flowers at their base with this mixture. This helps the roots absorb the nutrients effectively.


Gelatin is a great source of nitrogen, vital for robust foliage growth.


  • Stick to the recommended mixture ratio to avoid nutrient imbalance. Excessive application can harm your plants. It’s all about balance.
  • Watch how your flowers react to the fertilizer. Adjust your approach if you notice any signs of stress or overfertilization.

6. DIY Homemade Liquid Bloom Fertilizer

Liquid Bloom Fertilizer


  • Select fruits high in potassium and vegetables rich in beta-carotene. For North America, consider herbs or weeds like Comfrey for phosphorus. Good choices include carrots, squash, and pumpkin. In Asia, bananas, squash, pumpkin, papaya, mango, jackfruit, and pineapple are excellent.
  • Brown sugar or molasses aids fermentation.


  • Choose fruits based on regional availability and plant needs.
  • Combine fruits with an equal weight of molasses. For 1 kg of fruit, use 1 kg of molasses.
  • Place the mixture in a plastic jug, covering it loosely. Ferment for 7-10 days, adjusting for temperature.

Fermentation Tips

  • Optimal Temperature: Go for 25-30 degrees Celsius. Colder temperatures may prolong fermentation, which is acceptable.

Application Instructions

  • Dilute 1 tablespoon of fertilizer per 2 liters of water.
  • Suitable for foliar spray or soil drench during the bloom and fruiting phases.
  • Customizable for each growth stage.


Strengthens plants during flowering and fruiting. It improves fruit flavor and sweetness. Offers a 100% organic alternative to commercial formulas.


Avoid citrus fruits in the mix. Be mindful of application amounts to prevent plant damage. Store properly for longevity.

7. DIY Blackstrap Molasses

Blackstrap Molasses fertilizer


  • Blackstrap molasses & water.

Preparing the Solution

Combine 1 tablespoon of blackstrap molasses with 1 gallon of water. This ratio is important to maintain. Also, ensure the molasses completely dissolves in the water. This well-mixed solution delivers essential nutrients to your plants.

The best time to use this fertilizer is during the growing season, especially in spring and late summer. Water your flowers at their base with the molasses mixture. Be careful to avoid getting the solution on the leaves to prevent stickiness.


It is packed with vital minerals like potassium, calcium, magnesium, iron, and trace elements, all crucial for plant and flower growth. The sugars in molasses enhance microbial activity in the soil, improving its structure and nutrient availability.


  • Stick to the recommended dilution ratio and use it sparingly.

8. DIY Bloom Boosting Seaweed Fertilizer Recipe

Seaweed Fertilizer Recipe


  • Dried Seaweed


Begin by thoroughly rinsing the dried seaweed. This step removes excess salt, preventing soil salt buildup. Place the seaweed in a container, fully cover it with water, and soak it for 24-48 hours. The soaking period allows the seaweed to rehydrate and release nutrients.

Post-soaking, strain the liquid into a new container, separating the solid seaweed. This liquid is your valuable seaweed fertilizer.

Best applied from spring to late summer. Mix 1 part seaweed fertilizer with 4 parts water. Spray directly on plant leaves for foliage nutrient absorption. Combine 1 part seaweed fertilizer with 10 parts water. Use this to water plants at the base, aiding root nutrient uptake.


Seaweed fertilizer provides essential minerals like potassium, calcium, and magnesium. It contains natural hormones (cytokinins, auxins) that promote growth, flowering, and fruit development. Regular use can boost plant resilience to diseases and stress.


Adhere to recommended dilution ratios to prevent over-fertilization. Observe plants for reactions. Adjust concentration or frequency if you notice issues like leaf burn.
