How to grow cosmos flower at home

Growing Cosmos from Seeds

Choose the right location

Cosmos prefer full sun but can tolerate some light shade. They also need well-drained soil.

Get your timing right

  • Start your seeds indoors 6-8 weeks before the last frost. Alternatively, you can direct sow seeds outdoors after the last frost.
  • Sow your seeds about ¼ inch deep and 12-18 inches apart, then cover them with soil. Keep the soil moist until the seeds germinate, which usually takes 7-14 days.


When the seedlings have grown their first true leaves, transplant them into larger pots or your garden.

Growing Cosmos from Cuttings

Choose healthy parent plants

Choose a healthy and robust plant to take cuttings from. It should have solid stems and well-developed leaves.

Take cuttings

Using a sharp and clean pair of scissors or pruning shears, take 4-6 inch cuttings from the parent plant. Make sure each cutting has at least two sets of leaves.

Prepare the cuttings

Remove the lower leaves from the cuttings and dip the cut end into rooting hormone powder. It will encourage root growth.

Plant the cuttings

Plant the cuttings in well-drained soil, ensuring the leaves are above the soil line. Water the cuttings well and cover them with plastic to create a mini greenhouse.

Monitor the cuttings

Keep the cuttings in a warm and bright place but out of direct sunlight. Make sure to keep the soil moist and mist the cuttings regularly to prevent them from drying out.


Once the cuttings have rooted and have developed new growth, transplant them into larger pots or your garden.

How to take care of cosmos flower

Taking care of the cosmos flowering plant is an easy task. Just follow the instructions given below: -


Cosmos grow best in well-drained soil that is rich in organic matter. If your soil is heavy and clay-like, consider adding compost or peat moss to improve its texture. The soil pH should be between 6.0 and 6.7, slightly acidic to neutral.


Cosmos need at least 6 hours of sunlight each day, but they can handle more. If you're planting cosmos in a partially shaded area, choose a spot where they'll receive morning sunlight and some dappled shade in the afternoon.


When choosing a spot for your cosmos, consider the size of the mature plant. Some varieties of cosmos can reach up to 5 feet tall, so make sure to give them enough space to grow. They also look great in groups, so consider planting several together for a more dramatic display.


Cosmos are not heavy feeders, but a light application of a balanced fertilizer will help encourage healthy growth. Fertilize every 4 to 6 weeks during the growing season, but stop fertilizing when the flowers start to fade.


Cosmos prefer to be kept evenly moist, but they don't like being waterlogged. Water your plants deeply, but allow the soil to dry out slightly between waterings. Ensure the water is at the base of the plant to avoid wetting the leaves, which can encourage fungal diseases.


To guarantee successful germination, keep the soil temperature above 20 degrees Celsius. For a healthy Cosmos plant, the temperature should be between 13 and 16 degrees Celsius.


Cosmos will continue to bloom throughout the growing season if you remove the spent flowers regularly. Deadheading, as it is known, will help keep your plants looking neat and encourage more blooms to form.


Mulching your Cosmos will help keep the soil cool and moist and suppress weed growth. Spread a 2- to 3-inch layer of organic mulch around the base of the plant, being careful not to let the mulch touch the stems.

With patience and care, you'll soon have a beautiful, vibrant garden filled with colorful cosmos flowers.

Growing cosmos flowers is a beautiful and fun way to add color and life to your garden.
