Growing Manual for Gerbera

Growing Manual for Gerbera

Gerbera (Gerbera jamesonii) is a popular flowering plant known for its vibrant and daisy-like blooms. This growing manual is tailored to provide comprehensive guidance for the successful commercial production of high-quality Gerbera plants.

  1. Variety Selection

    • Choose Gerbera varieties based on market demand, color preferences, disease resistance, and growth habits.

  2. Optimal Growing Conditions

    • Light: Provide Gerberas with bright, indirect light. Supplemental lighting may be needed in low light conditions.
    • Temperature: Maintain temperatures between 60-75°F (15-24°C) during the day and above 50°F (10°C) at night.
    • Humidity: Maintain moderate humidity levels, ideally between 50-70%.

  3. Growing Media

    • Organic Media: Well-aerated potting mix containing cocopeat or coir, peatmoss, perlite, and coarse sand.
    • Water Holding Capacity: Around 45-55% by volume.
    • Cation Exchange Capacity (CEC): 8-12 meq/100g.
    • Air Porosity: 20-30%.Use a well-draining, soilless mix with good aeration and water-holding capacity. Consider a blend of cocopeat, peat moss, perlite, and composted organic matter.

  4. Propagation

    • Propagate Gerberas from seeds, divisions, or tissue culture. Seeds are typically started in a controlled environment.

  5. Transplanting and Planting

    • Transplant Gerbera seedlings or rooted cuttings with care, ensuring proper spacing for mature size and growth habit.
    • Plant at the same depth as in the original container and water thoroughly after planting.

  6. Irrigation Management

    • Employ an efficient irrigation system (drip, soaker hoses) to deliver consistent moisture to the root zone while minimizing leaf wetness.
    • Monitor soil moisture levels and adjust watering schedules based on plant needs and weather conditions.

  7. Nutrient Management

    • Develop a balanced fertilization plan based on regular soil or tissue testing. Adjust nutrient levels according to growth stage.
    • Apply a controlled-release or water-soluble fertilizer with emphasis on balanced micronutrient content.

  8. Lighting and Photoperiod

    • Provide supplemental lighting during short days to ensure plants receive the necessary light intensity for healthy growth and flowering.

  9. Temperature and Humidity

    • Maintain consistent temperatures and humidity levels to prevent stress and encourage uniform growth.
    • Avoid temperature extremes and cold drafts, which can lead to leaf damage.

  10. Pruning and Deadheading

    • Regularly remove spent blooms and dead or yellowing leaves to encourage continuous flowering.
    • Trim back overgrown or leggy stems to maintain a compact, bushy habit.

  11. Pest and Disease Management

    • Implement an integrated pest management (IPM) program to monitor and manage pests such as aphids, spider mites, and powdery mildew.
    • Use natural predators, insecticidal soaps, and horticultural oils for pest control. Apply fungicides when necessary.

  12. Staking and Support

    • Provide stakes or trellises for tall or heavy-stemmed Gerbera varieties to prevent stem breakage and promote upright growth.

  13. Harvesting and Post-Harvest Handling

    • Harvest Gerbera blooms when they reach a desirable size and color. Use clean, sharp shears to make a clean cut just above the crown.
    • Handle blooms gently to prevent bruising and damage, and place in water immediately.

  14. Quality Control and Record-Keeping

    • Establish quality control standards for bloom size, color, form, and overall plant health.
    • Keep detailed records of propagation, cultural practices, pest management, and harvest data.

  15. Troubleshooting and Problem-Solving

    • Regularly inspect plants for signs of stress, disease, or pest damage. Address issues promptly using appropriate measures.

  16. Sustainability and Environmental Considerations

    • Implement sustainable practices such as recycling pots and trays, conserving water, and utilizing organic pest control methods.

This professional growing manual provides a comprehensive framework for successful Gerbera production. Continuous monitoring, adjustment of practices, and attention to quality are essential for consistent high-quality yields.
