The Science Behind Bigger Flowers in Plants

The size of blooms in flowering plants is influenced by various factors, including genetics, environmental conditions, and cultural practices. While genetic factors play a significant role in determining the potential size of blooms, there are certain strategies you can employ to encourage larger blooms.

It’s important to note that not all flowering plants are genetically predisposed to produce large blooms. Each plant species has its own growth habits and characteristics, so managing expectations based on the natural size of the blooms is crucial.

Additionally, while the techniques mentioned above can promote larger blooms, it’s important to strike a balance and avoid excessive intervention, as it may negatively impact plant health.

Ultimately, by providing appropriate growing conditions, nutrition, and care, you can optimize the potential for larger blooms in your flowering plants.

How to Grow Bigger Flowers in Gerbera

1. Selecting Healthy Plants

Start with healthy Gerbera plants from a reputable source. Choose plants with strong, green foliage and no signs of pests or diseases.

Healthy plants are more likely to produce bigger and better blooms.

2. Provide Adequate Light

Gerberas thrive in bright, indirect light. Place them in a location where they receive at least 6-8 hours of bright, filtered sunlight each day.

Insufficient light can result in smaller blooms and weaker growth.

3. Optimal Temperature and Humidity

Gerberas prefer moderate temperatures between 60-85°F (15-28°C). Avoid exposing them to extreme heat or cold.

Additionally, maintain a relative humidity level of around 40-60% to provide a favorable environment for flower development.

4. Pick the Right Growing Medium

To promote the growth of bigger flowers in Gerbera daisies, it’s important to provide them with a well-draining potting mix that retains some moisture while allowing excess water to drain away. Here’s a suggested potting mix recipe for Gerbera daisies:


  • 1 part peat moss
  • 1 part perlite or vermiculite
  • 1 part well-aged compost or composted cow manure
  • 1 part garden soil or loamy soil

5. Adequate Watering

Water Gerberas consistently, keeping the soil evenly moist but not overly wet. Water deeply and allow excess water to drain out from the bottom of the pot.

Avoid waterlogged conditions, as this can lead to root rot. It’s best to water the plants in the morning to allow the foliage to dry before evening.

6. Fertilization

To promote bigger blooms in Gerbera daisies, follow these steps:

  • As the Gerbera daisies start to develop flower buds, switch to a fertilizer blend that is higher in phosphorus and potassium to support bloom development. Look for a water-soluble fertilizer with an NPK ratio of 10-20-20 or similar. Apply it every 7-10 days during the blooming period, after diluting it to 1/4 of its strength. Remember, the key here is to feed the plants frequently.
  • Apply a balanced water-soluble fertilizer with an NPK ratio of 10-10-10 or 14-14-14 every 2-4 weeks during the active growing season. Follow the instructions on the fertilizer package for the proper dilution ratio and application method.
  • Water the plants before and after fertilizing to ensure the nutrients are properly distributed and to prevent any potential burn from concentrated fertilizer.

7. Deadhead Spent Blooms

Remove faded or spent flowers regularly by gently pinching them off near the base of the stem. Deadheading redirects the plant’s energy towards producing new blooms instead of seed production, resulting in a continuous flowering cycle and potentially larger flowers.

8. Pruning and Staking

Gerberas can benefit from occasional pruning to remove damaged or diseased foliage. Additionally, staking taller varieties can help support the flower stems and prevent them from flopping over, allowing the flowers to display prominently.

9. Protect from Pests and Diseases

Monitor Gerberas for pests such as aphids, spider mites, and whiteflies. Treat infestations promptly with appropriate insecticides or employ natural pest control methods.

Additionally, avoid overwatering and promote good air circulation to prevent fungal diseases.

10. Overwintering Care

In regions with cold winters, Gerberas are often grown as annuals or potted plants. If you want to overwinter them, bring the plants indoors before the first frost and place them in a cool, well-lit area.

Reduce watering and fertilization during the dormant period, allowing the plants to rest before their active growth resumes in spring.

11. Use Fulvic Acid

Fulvic acid is a naturally occurring organic material found in humus, the decayed organic matter in soil. Known for its benefits in enhancing nutrient uptake, improving soil structure, and stimulating plant growth.

Fulvic acid enhances the nutrient absorption capabilities of plants by making it easier for minerals to pass through cell membranes. This could potentially lead to larger, fuller blooms due to better nutrient uptake.

Use a fulvic acid supplement that is specifically designed for flowering plants, typically at a concentration of 0.5-1%. For best results, apply during the growing season, especially during the pre-flowering and flowering stages.

12. Use Mycorrhizal FungiBigger Flowers in Gerbera 12

Mycorrhizal fungi form a symbiotic relationship with plant roots, aiding in nutrient and water absorption. This not only enhances the overall health of the plant but also allows for optimal flower growth and size.

The best time to introduce mycorrhizal fungi is during planting or repotting, as direct contact with the roots is essential for mycorrhizal colonization. Mix 1-2 teaspoons in the growing medium per pot, water well, and wait for the results!

Observe your Gerbera plants to gauge the effectiveness of the treatment. You can adjust your care routine based on how well the plants respond to the mycorrhizal fungi.

13. Go for Boron and Molybdenum

Boron is crucial for cell division and is essential for flower and seed development. It helps in the efficient uptake of nutrients and enhances the plant’s water absorption capabilities. In the case of Gerberas, a deficiency in boron may lead to smaller, less vibrant blooms.

Molybdenum plays a role in the fixation of nitrogen from the soil, helping to enhance overall plant growth and vigor. A molybdenum-boosted plant is likely to exhibit better flower growth.

Dosage and Timing

  • Boron: A concentration of 0.2 to 1.0 ppm in the soil is generally sufficient for most plants, including Gerberas.
  • Molybdenum: A lighter touch is required, with an ideal concentration of 0.01 to 0.05 ppm in the soil.
  • Timing: Apply these micronutrients during the growing season, particularly during the pre-flowering and flowering stages.

Caution: Excessive amounts of boron or molybdenum can be toxic to plants, leading to reduced growth or even death.
