- Soil requirements: Gomphrena prefers well-drained soil with a pH level between 6.0 and 7.5. The soil should be moderately fertile and have good drainage to prevent waterlogging.
- Sunlight needs: These plants thrive in full sun, requiring at least 6-8 hours of direct sunlight per day.
- Watering requirements: Gomphrena is drought-tolerant once established. Water the plants moderately, allowing the soil to dry out between watering sessions. Overwatering can lead to root rot.
- Planting season: The best time to plant Gomphrena seeds is in the spring after the last frost has passed. They can also be started indoors 6-8 weeks before the last expected frost date.
- Depth and spacing: Plant the seeds at a depth of 1/4 inch (0.6 cm) and space them about 12-18 inches (30-45 cm) apart to allow for adequate air circulation and growth.
- Germination time: Gomphrena seeds typically germinate within 7-14 days under optimal conditions.
- Maturity time: Gomphrena plants usually reach maturity and start blooming within 8-10 weeks after planting.
- Harvesting time: The best time to harvest Gomphrena flowers is in the morning after the dew has dried but before the heat of the day sets in.
- Harvesting tips: Use sharp scissors or pruning shears to cut the flowers. For dried arrangements, hang the flowers upside down in a cool, dark, and well-ventilated area. Store harvested flowers in a dry place to maintain their color and shape.
