Growing zinnias from seeds is a relatively easy and rewarding process. Zinnias are colorful annual flowers that bloom in a variety of shapes and sizes. Here’s a step-by-step guide on how to grow zinnias from seeds:
Zinnia Magellan Materials needed:
- Zinnia seeds
- Seed-starting mix or potting soil
- Seed trays or small pots
- Watering can or spray bottle
- Plastic wrap or a humidity dome (optional)
- Grow lights or a sunny windowsill
- Transplant pots or garden bed (if starting indoors)
Steps:
- Starting Indoors (Optional):
- Zinnias can be started indoors 4-6 weeks before the last expected frost in your area. Fill seed trays or small pots with seed-starting mix.
- Sowing Seeds:
- Plant zinnia seeds about 1/4 inch deep in the soil. Space the seeds according to the recommended spacing for the specific zinnia variety you are growing.
- Watering:
- Keep the soil consistently moist, but not waterlogged. Use a watering can or spray bottle to avoid disturbing the seeds. Ensure proper drainage to prevent seed rot.
- Germination:
- Zinnia seeds typically germinate in 7-10 days. If starting indoors, maintain a warm environment (around 70-75°F or 21-24°C) to encourage germination.
- Light:
- Once the seedlings emerge, provide them with plenty of light. If growing indoors, use grow lights or place them in a sunny windowsill. Zinnias thrive in full sun, so ensure they receive at least 6-8 hours of sunlight daily.
- Transplanting (if started indoors):
- When the seedlings have developed a couple of sets of true leaves, they can be transplanted into larger pots or directly into the garden after the last frost date in your area.
- Outdoor Planting (if started outdoors or after last frost):
- If starting directly in the garden, sow the seeds directly into well-prepared soil after the last frost date. Space them according to the variety’s recommendations.
- Care:
- Water the zinnias consistently, but be mindful not to overwater. Zinnias are generally drought-tolerant once established. Provide support for taller varieties if needed.
