Soils lacking balanced nutrients such as nitrogen, phosphorus, and potassium affect bloom for most flowering plants, including Gerberas. In addition, Gerbera Daisies also require extra magnesium and iron to provide a continuous bloom. Using NPK fertilizers, including at least one of two trace minerals iron and magnesium is best. Unless you are using controlled-release fertilizer, which lasts longer feed the soil in which your Gerberas are growing once a month.

Nutrients needed for Gerbera to grow and bloom

  • Nitrogen – It helps in root and steam growth and provides a strong foundation for the plant. 
  • Phosphorus – It helps the roots to absorb nutrients better. 
  • Potassium – It protects the Gerbera from diseases and helps in Gerbera color.
  • Magnesium – Helps plants to process sunlight better. 
  • Sulfur – Provides Gerbera with extra protein, which is essential for a strong life.
  • Iron – Helps to have a strong foundation of Gerbera.
  • Manganese – Helps in the Gerbera growth and process of sunlight.

So, to provide an ideal homemade fertilizer is to buy the nutrients of these commercial plants and then mix them based on the objectives that they have to offer once in use. Nitrogen generally helps enrich plant leaves, phosphorus promotes the growth of flowers and fruits, while potassium improves plant trunks and roots.


Vermicompost is a nutritious organic fertilizer and soil conditioner which is relatively easy to absorb for plants. worm castings are sometimes used as organic fertilizer.

Organic and liquid fertilizers for Gerbera Daisy 

Fish emulsion or seaweed mixture

Provide your Gerbera Daisies with a high-quality micronutrient-rich liquid plant fertilizer. Both fish emulsion and seaweed are well-advised.

Compost tea

Compost tea reduces nutrients, making it easier for plants to use faster. It also helps the soil to maintain water, reduces fertilizer use and attendant salt accumulation, and improves soil pH to levels that encourage nutrient and moisture use by plants.

Alfalfa meal

Alfalfa meal act as a slow-release fertilizer, a great source of nitrogen. It is beneficial for adding nitrogen, phosphorus, and potassium as well as tracking minerals and contains triacontanol which is a natural growth stimulant. Microorganisms present in soil take advantage of this and also benefit from plants and create more underground activity by providing food for them.  

Kelp Meal

The use of kelp meal for plants is not only a good idea as it is a natural fertilizer, thus nourishing the plant, but it also encourages your plants to extract nutrients more effectively from the soil in general. 

Bone meal fertilizer

Bone meal fertilizer makes your plants a fantastic organic compost to supply vital nutrients like calcium and phosphorus, promoting strong, healthy plants and production. Soil testing is essential before fertilizing bone meal in your garden. This will help you determine whether this is the right choice for your soil.

Commercial fertilizers for Gerbera Daisy 

NPK ratio 

Gerbera should be fed with a fertilizer based on nitrate and not ammonium. While ammonium-based fertilizer promotes large leaves and more shading. The first fertilizer application should be applied about 10-14 days after germination using formulas like about 75-100 ppm nitrogen 15-5-15. Avoid applying fertilizer directly to the leaves if the leaves are soft.

Otherwise, wash Leaves with fresh water after each fertilizer is used. Formulations that provide excess potassium, such as 15-3-20, forms strong plants with a total count of high flowers. Feed plants every two weeks with water-solving fertilizers, such as a 24-8-16 formula.

Soil pH above 6.2 can cause micronutrients like iron to be unavailable for Gerbera. Iron chlorosis often results when this happens. The main symptom is the gradual yellowing of young leaves of plants, which does not change the green veins. Spray Gerbera leaves with chelated iron and switch to more acidic fertilizer, such as 20-10-20. 

Calcium and manganese

If soil pH is less than 5.5 it can be problematic for Gerbera, as it often causes calcium and magnesium to be tied to the soil. Calcium deficiency causes blossom end rot and distorts the growth of new leaves. Spread calcium nitrate on Gerbera in small doses until you start seeing improvement in plant condition.  


You don’t need a test to see if your plants need magnesium. Lack of magnesium causes the leaves of the old Gerbera to turn yellow around the edges, leaving the green center of the arrow-shaped. This can also be treated. Mix about 28 grams of Epsom salt in 5 gallons of water. Apply this solution weekly to your Gerbera bed.

Gerbera Daisy fertilizer schedule

  • When you should fertilize Gerbera, it depends on the Gerbera (annuals or perennials), when Gerbera blooms, and the fertilizer you use. After planting, start showing fertilized garden Gerbera Daisies or once perennial plants new growth in spring. Apply slow-release, low phosphorus fertilizer, such as 15-5-15, at the rate recommended on the package for your bed size.
  • Water the plants immediately after fertilizing, rinse the leaves with water. The leaves are easily burnt by contact with fertilizer.
  • Fertilize for the second time two months after the first application. Apply for a third application two months after the second application.
  • Spray the Gerbera Daisies with iron foliar spray in the middle of summer if the leaves start to yellow. Gerbera Daisies is iron deficient. Follow the instructions on the spray label for proper application procedure and amount.
  • Gerberas may suffer from iron and manganese deficiencies, especially in potting soil; therefore, use a granular fertilizer or foliar manure spray to contain these micronutrients.

How to fertilize Gerberas in pots

Gerberas should be planted in a well-draining potting mix that includes part perlite and part coarse sand. They may suffer from root rot and will not survive in soggy conditions. Feeding plants once a month with high potassium fertilizer will encourage plentiful blooms. You can use a mixture of potting soil regularly, but we recommend making it a little sandy. This will maintain more moisture and ensure a humid environment where Gerbera Daisy can thrive. 

Gerbera Daisies benefit greatly indoors from monthly feeding with fertilizer for houseplants or blooming plants during warm months. Do not compost during winter or fall, as your Daisy will be inactive and won’t help. Garber Daisies benefit from monthly doses using regular fertilizer for household plants or blooming plants during spring and summer.

For indoor plants, it is better to use a fertilizer that is formulated for blooming parts. Follow the package instructions on how much fertilizer to use based on the size of your container. Fertilize your Gerbera during the growing season (mid-spring to early summer) but avoid doing so.

Frequently asked questions about fertilizers for Gerbera Daisy (FAQ)

Can I use Miracle-Gro on the Gerbera Daisies?

An all-purpose fertilizer, such as Miracle-Gro water-soluble all-purpose plant food, will be well suited to your Gerbera Daisies.

How do you make Gerbera Daisies bloom more?

Compost with a water-soluble fertilizer every two weeks with a small quantity of phosphorus (e.g., 15-7-15 or 12-2-12). This will help in blooming and not in the growth of leaves. Gerberas will not bloom continuously. They bloom, then take a break of about two weeks to refuel then bloom again.

Why are my Gerbera leaves turning yellow?

Gerbera Daisy leaves can be yellow due to excessive water or too much water in the soil. Too much water can result in root rot, and nutrients will not be absorbed from the soil. This can weaken plants and result in yellow, brown, or red leaves.

Why are my Gerberas have short stems?

Like most annuals, Gerbera Daisies are heavy feeders, make sure to fertilize regularly. Cold temperatures, dry conditions, or high salt intake can also cause flower stems to shorten.
