  • Soil requirements: Giant red zinnia flower seeds prefer well-drained, fertile soil with a pH level between 5.5 and 7.5. The soil should be rich in organic matter to support healthy growth.
  • Sunlight needs: These seeds require full sun exposure, which means they need at least 6 to 8 hours of direct sunlight each day.
  • Watering requirements: Zinnias need moderate watering. Water the plants deeply once a week, ensuring the soil remains moist but not waterlogged. Avoid overhead watering to prevent fungal diseases.
  • Planting season: The best time to plant giant red zinnia flower seeds is in the spring, after the last frost has passed. They can also be planted in early summer.
  • Depth and spacing: Plant the seeds at a depth of 1/4 inch (0.6 cm) and space them about 12 to 18 inches (30 to 45 cm) apart to allow for proper air circulation and growth.
  • Germination time: The seeds typically germinate within 7 to 10 days under optimal conditions.
  • Maturity time: Giant red zinnias usually reach maturity and start blooming within 60 to 70 days after planting.
  • Harvesting time: The best time to harvest zinnia flowers is early in the morning when the blooms are fresh and hydrated.
  • Harvesting tips: Use sharp scissors or pruning shears to cut the flowers. Make the cut just above a set of leaves or a branching stem to encourage more blooms. Store the cut flowers in a vase with clean water, and change the water every couple of days to prolong their freshness.
