Moisture and Temperature

1. Optimal Temperature: Trailing Lobelia Cascade Mix seeds germinate best in temperatures between 65-75°F (18-24°C). Ensure that the growing environment remains consistently warm, as fluctuations in temperature can affect seed germination and seedling growth.
2. Warmth for Germination: Provide consistent warmth during the germination period by placing the seed trays in a warm location, such as near a south-facing window or on a seedling heat mat. Avoid placing the trays in drafty areas or near sources of cold air.
3. Moisture Control: Maintain even moisture levels in the seed starting mix throughout the germination period. Use a spray bottle or watering can with a fine nozzle to water the trays gently, ensuring that the soil surface remains moist but not waterlogged. Avoid letting the soil dry out completely between waterings, as this can inhibit seed germination.
4. Cover to Retain Moisture: Consider covering the seed trays with a clear plastic dome or plastic wrap to create a humid environment that retains moisture. This helps prevent the soil from drying out too quickly and promotes uniform germination. Remove the cover once seedlings emerge to prevent mold growth and allow for adequate air circulation.
5. Humidity Control: Monitor the humidity levels around the seed trays, especially if you're using a plastic dome or cover. While some humidity is beneficial for seed germination, excessive moisture can lead to fungal problems and damping off. Use a humidity meter or hygrometer to track humidity levels and adjust ventilation as needed.
6. Watering Technique: Water the seed trays gently and evenly to avoid displacing the seeds or causing soil compaction. Use a fine mist sprayer or watering can with a gentle shower setting to moisten the soil surface without disturbing the seeds. Water early in the day to allow excess moisture to evaporate and minimize the risk of fungal diseases.
7. Proper Drainage: Ensure that the seed trays or containers have adequate drainage holes to prevent waterlogging and allow excess moisture to drain away from the soil. Use well-draining seed starting mix and avoid overwatering, as saturated soil can lead to root rot and other issues.

By carefully managing moisture levels and temperature, you can create optimal growing conditions for Trailing Lobelia Cascade Mix seeds, promoting successful germination and healthy seedling growth.
