From Seeds

Prepare a seed compost mixture by combining seed compost with one-third perlite to ensure good drainage and aeration.

Sow seeds in early spring in modular trays or individual pots filled with the compost mixture. Sprinkle seeds on the surface and lightly cover them.

Place trays or pots in a heated propagator set to 68-77°F (20-25°C). Keep the soil moist but not waterlogged.

Transplant seedlings once they are large enough to handle and the danger of frost has passed.

From Cuttings

Select healthy, non-flowering stems and cut 4-6 inches off the top. Remove leaves from the bottom half and place the cuttings in water, ensuring the leafless part is submerged.

Position the container in bright, indirect sunlight. Change the water weekly.

Transplant cuttings with developed roots into potting medium or directly into the garden.

Growing Celosia In The Garden

Wait until all danger of frost has passed. Loosen soil to a depth of 6 inches. Sow seeds 1/8 inch deep, spacing them about 8 inches apart.

Keep soil evenly moist until germination, which occurs in 1-2 weeks at 70-80°F.

Thin seedlings to 10-12 inches apart once they are a few inches tall to allow adequate space for growth and air circulation.

Care for Celosia Flowers

Here are main requirements for Celosia flowers:

  • Plant in well-draining soil with a well-drained potting mix; Richer soil produces more vibrant blooms.
  • Ensure Celosia receives at least six hours of full sun daily.
  • Water regularly but allow the soil to dry out between waterings.
  • Apply a balanced, high-nitrogen fertilizer once a month.
  • Celosia is a true annual, completing its life cycle in one growing season.



Celosia thrives in full sun, requiring at least 6-8 hours of direct sunlight daily.

Adequate light ensures vibrant blooms and healthy growth. Insufficient light can result in leggy plants and reduced flowering.



Celosia requires well-drained soil with a pH of 6.0-7.0. Amend with compost to retain moisture and regulate temperature.

Poorly draining soil can lead to root rot and other moisture-related issues.



Keep the soil consistently moist but not waterlogged. Provide about 1 inch of water per week.

Water at the base to avoid wetting the foliage, which can lead to fungal diseases. Ensure good drainage to prevent root rot and promote healthy growth.


Temperature and Humidity

Celosia prefers warm temperatures between 70-80°F (21-27°C) and thrives in moderate humidity. Protect the plants from frost and cold drafts.

High humidity levels combined with poor air circulation can lead to fungal diseases, so ensure adequate ventilation.

Cut 1-2 inches below spent blooms at a 45-degree angle to encourage continuous flowering and maintain plant health.

Remove any damaged or diseased foliage in the same manner to prevent spread. This helps keep the plant looking tidy and promotes vigorous growth.



For taller varieties of Celosia, staking prevents plants from toppling in wind conditions. Use gentle ties and stakes to ensure stability without damaging the plants.



Use a balanced fertilizer with an NPK ratio of 10-10-10 or a high-nitrogen fertilizer for Celosia. Apply once a month during the growing season.

Pests and Diseases

Aphids are small, pear-shaped insects, under 1/8 inch long. They cluster on the undersides of leaves and stems of Celosia, sucking sap and causing distorted growth and yellowing leaves.

Their excretion of honeydew leads to sooty mold. Control them with water sprays, insecticidal soap, or neem oil.

You can also use natural predators like ladybugs or grow nasturtiums and lavender as trap crops.



Spider mites, about 1/50 inch long, create fine webs on leaf undersides. They suck sap, causing stippling, yellowing, and leaf drop.

To manage spider mites, increase humidity around the plant by misting, use miticides or insecticidal soap, and regularly inspect plants, removing affected leaves as necessary.

Powdery mildew appears as white, powdery fungal growth on leaves, stems, and flowers of Celosia. It causes yellowing and curling of leaves, reduced flowering, and weakened plant health.

Improve air circulation, water at the base, apply fungicides if needed, and remove affected parts to manage this disease.

Common Problems

Yellowing Leaves

Yellowing leaves can be caused by overwatering, poor drainage, or nutrient deficiencies. Ensure well-draining soil, avoid waterlogging, and provide balanced fertilization to prevent yellowing.


Stunted Growth

Stunted growth is often due to inadequate sunlight, poor soil nutrition, or root-bound conditions. Provide full sun exposure, enrich the soil with nutrients, and transplant if needed.



Harvest Celosia flowers when they are fully open and vibrant. The best time to harvest is in the morning, after the dew has dried but before the heat of the day.

Use clean, sharp scissors or garden shears to cut the stems at the desired length, just above a leaf node or lateral bud to encourage further blooming.

Storing Seeds

Allow some flowers to remain on the plant until they dry out and turn brown. Cut the dried flower heads and place them in a paper bag.

Shake the bag to release the seeds from the flower heads or manually separate the seeds by gently rubbing them.

Once completely dry, store the seeds in a paper envelope or a glass jar with a tight-fitting lid. Label the container with the date and variety of the seeds.

Keep the seeds in a cool, dark, and dry place until you are ready to plant them next season. Properly stored seeds can remain viable for up to one year.
