Study Notes
Module 3: Production and Management of Bedding Plants
- Lesson Objectives: Discuss bedding plant production management and determine water, light, temperature, and soil requirements.
- Timeframe: 4 hours
- Introduction: Focuses on the importance of selected bedding plants and factors affecting their growth and development. Includes cultural management practices like nutrition, growing media, water, light, and favorable environment.
- Activity (Let's Check!): List five common bedding plants in your local area.
- Analysis: Describe important features of bedding plants.
Bedding Plant Production
- Introduction to Bedding Plants: Mostly fast-growing annuals, typically propagated from seeds. Started in sheltered conditions, then moved to larger containers or beds.
- Seed Procurement & Storage: Select high-quality seeds with good germination rates. Store seeds at low temperatures (0°C to 5°C) and low humidity to maintain viability and vigor.
- Germination Media: Sanitized media should be well-drained and retain moisture. Coconut coir and sand (3:1 v/v) or sandy loam:coco peat:sand (1:1:1 v/v/v) are suitable mixes. Adjust pH to 5.5-6.0, and aim for a light (26 kg/0.028 cubic meter wet) bulk density.
- Sowing: Row or broadcast sowing. Cover seeds with medium, and water seeds thoroughly. Prevent the medium from becoming excessively soggy.
- Lighting: Some seeds require light during germination while others need darkness. Specific light requirements vary among species. Exposure to light or darkness before germination is critical for some. Ideal temperature for germination for many bedding plants fall between 20°C and 26°C.
- Transplanting: Transplant when seedlings have developed 2-3 true leaves, not cotyledons. Harden plants prior to transplanting by gradually adjusting the watering and light intensity. Transplant seedlings into moist but not saturated soil. Don't fertilize for at least a week after transplanting.
- Essential factors for growth up to flowering: Light intensity, duration, and quality; temperature, water, and nutrients
- Daylength and Bedding Plants: Table 5.2 shows specific day-length requirements for different bedding plants.
- Categorization of bedding plants based on nutritional requirements: Impatiens need a light to moderate amount of nutrients, while other plants may require a moderate amount or more. (Table 5.3)
