Growing flower bulbs with optimal plant nutrition

Flower bulb cultivation requires a precise balance between growth, flower quality and bulb development. Crops such as tulips and dahlias must experience strong leaf and stem growth in a relatively short period, followed by good flower formation and the development of healthy bulbs. A balanced nutrient supply plays an important role in this.

Proper plant nutrition not only supports crop growth, but also contributes to strong plants, uniform flowers and proper bulb development. In addition, optimal nutrition helps the plant better cope with stress factors such as temperature fluctuations, soil conditions and varying moisture availability.

Biota Nutri develops high-quality plant nutrition, micronutrients and biostimulants that support growers in healthy and efficient flower bulb production. Our solutions are suitable for both organic growers and conventional growers and are compatible with various growing systems.

Plant food for tulips and dahlias

Tulips and dahlias need a balanced supply of macro- and micronutrients as they grow. Elements such as nitrogen, phosphorus and potassium are important for basic plant growth, while trace elements contribute to enzymatic processes and efficient metabolism.

In addition to basic fertilization, supplemental plant nutrition can contribute to better crop development. In flower bulb cultivation, leaf fertilizers and biostimulants are therefore increasingly used to support nutrient uptake.

With the right combination of nutrients and biostimulants, growers can optimally support the growth, flower quality and bulb development of their crops. Below is a selection of our solutions:

Biota Iron Powder


Biota Iron Powder is an organic iron fertilizer in powder form with a high concentration of iron. The product is designed to quickly and efficiently supplement iron deficiencies in crops and supports chlorophyll production. Its good solubility makes it suitable for application via irrigation and foliar feeding.

  • It prevents and restores iron deficiency (chlorosis) in the crop
  • It stimulates the production of chlorophyll and a deep green leaf color
  • It is well soluble and easy to apply in different cultivation systems

Biota Amino Complex Foliar


Biota Amino Complex Foliar is a liquid foliar fertilizer based on plant amino acids. The product supports the plant during stress moments and stimulates metabolism, allowing nutrients to be absorbed and utilized more efficiently. This makes it very suitable for intensive crops and critical growth stages.

  • It helps plants recover and perform better under stress
  • It improves nutrient uptake and utilization
  • It stimulates active metabolism and crop growth

Additional nutrient elements for growing flower bulbs

The exact nutrient requirements can vary from one crop to another. Factors such as crop type, soil structure, cultivation system and plant growth stage play an important role in this.

For example, the nutrition for tulip bulbs may be different from the nutrition for dahlia bulbs, and the time when bulbs are planted or harvested may also affect the nutrient requirements of the crop.

That’s why we like to work with growers to look at the specific situation within their farm. Based on growing conditions, soil analysis and growing goals, we can create a nutrition strategy that meets the needs of your crop.

Challenges in flower bulb production

Growing flower bulbs, such as tulip bulbs and dahlia bulbs, has several challenges. Growers strive for uniform growth and high flower quality, while conditions can vary widely throughout the growing season.

Common challenges in flower bulb production are:

  • high demands on flower quality, uniformity and color development
  • susceptibility to stress due to temperature, soil structure or moisture conditions
  • efficient uptake and utilization of nutrients by the plant

In addition, flower bulbs go through several important growth stages. After planting the bulbs, root development begins and vegetative growth begins. During this phase, proper nutrient uptake is essential for strong plants and healthy leaves. Next, flower formation takes place, focusing on flower quality and uniformity. Finally, bulb development plays an important role, because in this phase reserves are stored for the next cultivation cycle.

A well-tuned plant food helps to provide optimal support for these growth stages.

How Biota Nutri supports growers

Biota Nutri develops circular, plant-based and fully soluble fertilizers that are well suited to modern flower bulb crops. Our products are derived from waste streams from the food industry and contain no sodium or chlorides. This makes them suitable for a variety of growing systems, including open cultivation, substrate cultivation and specialty nurseries.

Our approach aligns perfectly with growers who strive for:

  • strong and resilient plants in flower bulb cultivation
  • efficient utilization of nutrients
  • support of the crop during moments of stress
  • uniform growth and consistent flower quality
  • stable yields and healthy bulb development

Our approach is supported by practical results at home and abroad. Feel free to ask about our experience with similar crops.

    How do I care for my tulip bulbs?
    Tulip care begins with planting healthy tulip bulbs in well-drained soil. During growth, it is important that the plant can absorb sufficient nutrients. A balanced plant nutrition supports strong leaf development and contributes to good flower quality.

    What nutrition should I give to my flower bulbs?
    Flower bulbs need a balanced supply of macro- and micronutrients. In addition to basic fertilization, supplemental plant nutrients can help support growth and flower formation. Biostimulants can additionally contribute to more efficient nutrient utilization and improved crop resilience.

    My dahlias are not growing well, what nutrition can I give?
    When dahlias do not grow as well, it can have several causes, such as nutrient deficiency or stress due to soil or weather conditions. Providing the plant with proper nutrition and additional biostimulants can help support growth and help the plant recover.
