Why to Grow Celosia from Seeds?
Growing celosia from seeds is a rewarding experience that allows you to witness the entire life cycle of the plant. It also gives you more control over the growing conditions and allows you to choose from a wider variety of cultivars. Additionally, growing celosia from seeds is more cost-effective than buying established plants.
How to Grow Celosia from Seed
Start by choosing a location for your celosia seeds. Celosia plants thrive in full sun and well-draining soil. You can either start your seeds indoors or directly sow them in the garden after the danger of frost has passed.
1. Gather Your Supplies
Before you start, gather all the necessary supplies. You will need:
- Celosia seeds
- Seed starting trays or pots
- Seed starting mix
- Watering can or spray bottle
- Grow lights or a sunny location
- Plastic wrap or a humidity dome
2. Start Celosia Seeds Indoors
Start your celosia seeds indoors about 6-8 weeks before the last frost date in your area. Fill the seed starting trays or pots with a moist seed starting mix and sow the seeds according to the package instructions. Celosia seeds are tiny, so sprinkle them lightly on the surface of the soil and cover them with a thin layer of soil and mist them with water.
3. Provide Optimal Growing Conditions
Place the seed trays or pots in a warm, bright location with temperatures around 70-75°F (21-24°C). Celosia seeds require consistent moisture to germinate, so make sure to keep the soil evenly moist. You can cover the trays with plastic wrap or a humidity dome to create a greenhouse-like environment.
Once the seeds have germinated, which usually takes around 7-14 days, thin them out by removing the weaker seedlings. This will allow the stronger plants to grow and develop properly.
4. Transplant Seedlings
Once the seedlings have developed a few sets of true leaves, they are ready to be transplanted into individual pots. Gently lift the seedlings from the trays and plant them in well-draining soil. Keep the soil moist and provide adequate light to promote healthy growth. Celosia does not like to have its roots disturbed by transplanting. Transplant the entire pot into the soil at the time of transplanting. This will minimize transplant shock.
5. Harden Off and Plant Outdoors
About a week before the last frost date, start hardening off your celosia seedlings. Gradually expose them to outdoor conditions by placing them outside for a few hours each day, gradually increasing the duration. After the last frost, choose a sunny location in your garden and plant the seedlings, making sure to space them 6-12 inches apart, according to the specific variety's requirements.
6. Start Celosia Seeds Outdoors
After the threat of frost has passed, the seeds can be sown directly into the garden. This is only recommended for regions with long growing seasons.
7. Maintain and Enjoy
Once your celosia plants are established, they require minimal maintenance. Water them regularly, especially during dry spells, and remove any weeds that may compete for nutrients. Deadhead the flowers to encourage continuous blooming.
Fertilize the plants every two weeks with a balanced fertilizer, or use a slow-release fertilizer when planting.
Watch out for pests and diseases, such as aphids, spider mites, and powdery mildew. Treat any infestations or infections promptly.
Sit back, relax, and enjoy the stunning display of vibrant celosia flowers in your garden.
Growing celosia from seeds is a rewarding and cost-effective way to add a burst of color to your garden. By following these simple steps, you can successfully grow celosia from seeds and enjoy the beauty of these unique flowers.
