Getting Started with Celosia
Celosia prefers warm weather and ample sunlight. Knowing when and how to start your seeds is crucial for successful celosia cultivation.
Starting Seeds Indoors
In cooler climates, it’s best to start celosia seeds indoors approximately 6 weeks before the last expected frost. Use a seed-starting mix and sow the tiny seeds shallowly, barely covering them with soil. Maintain a temperature of around 70-75°F (21-24°C) and keep the soil consistently moist.

Direct Sowing
If you live in a warmer region, you can direct sow celosia seeds into your garden once the soil temperature has reached at least 60°F (16°C) and the danger of frost has passed. Choose a location with full sun and well-draining soil. Scatter the seeds thinly and cover them lightly with soil.

Planting and Caring for Celosia
Once your celosia seedlings have developed a few true leaves, they are ready to be transplanted outdoors.
Soil Preparation
Celosia thrives in fertile, well-draining soil. Amend your garden bed with compost or other organic matter to improve soil structure and fertility.

Planting and Spacing
Space your celosia plants 9 to 12 inches (23 to 30 cm) apart to allow for adequate air circulation and prevent overcrowding. Water deeply after planting.
Watering
Celosia prefers consistently moist soil, especially during hot, dry weather. Water deeply twice a week, or more often if necessary, ensuring the water reaches the roots.

Pinching
When your celosia plants reach 6 to 8 inches (15 to 20 cm) tall, pinch back the central stem by removing the top 3 to 4 inches (7 to 10 cm). This encourages bushier growth and more flower production.

Supporting Taller Varieties
Taller celosia varieties may require staking or other support to prevent them from flopping over, especially in windy conditions.
Harvesting and Drying Celosia
Celosia flowers are prized for their long vase life and their ability to dry beautifully.
Harvesting
Harvest celosia flowers when they are the desired size and before they begin to go to seed. Remove most of the foliage from the stems to prolong their vase life.

Drying
To dry celosia flowers, hang freshly cut stems upside down in a cool, dark, and well-ventilated area for 2 to 3 weeks. Once dry, they can be used in dried flower arrangements.
