1. Seed Germination
- Timing: Seeds are typically sown indoors in late winter or early spring.
- Conditions: Geranium seeds need light to germinate, so they should be lightly pressed into the surface of the soil rather than covered. Keep the soil moist but not soggy. A temperature of 65-70°F (18-21°C) is ideal.
- Germination period: Seeds typically take 14-21 days to germinate, depending on conditions.
2. Seedling Growth
- Stage: After germination, tiny seedlings will begin to grow, developing their first true leaves.
- Care: During this stage, it’s important to keep the seedlings in a warm, bright area with indirect sunlight. Regularly water the plants but avoid overwatering. As they grow, ensure the seedlings are not too crowded.
- Transplanting: Once seedlings have developed a few sets of leaves and the risk of frost has passed, they can be hardened off and then transplanted into larger containers or directly into the garden.
3. Vegetative Growth
- Stage: Geraniums grow as young plants, developing more stems, leaves, and roots.
- Care: Regular watering is key during this period, but avoid letting them sit in waterlogged soil. Fertilizing once a month with a balanced liquid fertilizer can promote strong growth.
- Time Frame: This phase typically lasts until early summer, depending on growing conditions.
4. Flowering
- Stage: Geranium 'Custard Cream' will begin to produce its characteristic yellow flowers around late spring or early summer, once the plants are well-established.
- Flowering Period: The flowers usually bloom continuously throughout the summer, sometimes until the first frost, as long as the plant is properly maintained.
- Care: Deadheading spent flowers encourages the plant to continue producing blooms and keeps the plant looking tidy.
5. Seed Production
- Stage: After flowering, geraniums will produce seed pods that contain seeds for the next generation. These typically appear in late summer or early fall.
- Care: If you want to collect seeds, allow the pods to dry on the plant. Once fully dry, you can harvest the seeds and store them for future planting.
