Instructions Chevron Down Chevron Forward
    Growing Instructions:

    Cosmos seeds can be sown directly into the garden when the soil is warm and all danger of frost is passed. Soil temperature (not air temperature) should be warmer than 20°C (68°F) for seeds to germinate. Planting at a lower temperature will delay germination. Choose a location that receives at least 6 hours of sunlight daily. Space seeds and plant to the depth indicated below. Press seeds into the soil to ensure good contact and cover with 6 mm (1/4") of soil. After planting, water the seeds with a gentle mist or shower. A hard spray can wash soil away, dislodge seeds and clump them together. It is critical to keep the soil consistently moist, but not soggy during germination. Do not let the soil dry out, as young plants have underdeveloped roots and can quickly dehydrate, particularly in windy conditions. When your seedlings reach a height of a few centimetres (inches) and have developed 2 or 3 pairs of leaves, it is important to thin them out, according to the plant spacing indicated below to provide good air circulation and room to grow.

    For earlier blooms, seeds can be started indoors 4-6 weeks before the last frost in your area. Follow the seed depth and spacing guidelines indicated below. Once all danger of frost has passed, seedlings should be hardened off before planting in their growing location. Seedlings should be transplanted according to the plant spacing directions below. Regularly monitor your plants and ensure that the soil remains moist, while they establish themselves in their new environment.

  • Planting Depth: 6 mm (1/4")
  • Seed Spacing: 2.5 cm (1")

  • Instructions for Nutrient Care: Feed plants SUPERthrive once per week. Mix 1.2 ml (1/4 tsp) per 4L (1 gallon) of water in a watering can and apply solution to the base of the plants.
  • Plant Spread: 20-30 cm (8-12")
Suggestions Chevron Down Chevron Forward
Growing Suggestions:
  • Once established, cosmos can tolerate dry soil. Be careful not to over-water or over-fertilize as this can lead to less flowering.
  • Pinching back the early flower buds will help your plants to promote more branches and grow bushier. Wait until the plant is 20-25 cm (8-10") tall, cut off the top couple 5 cm (2") of the plant, directly above a set of leaves. Within a week, you will notice new stems sprouting from where you had cut the plant. This process will also cause the entire plant to branch out even more, giving rise to additional stems. The new stems will be longer because they will grow from the bottom of the plant instead of along the main stem.
  • Regularly removing spent flowers, known as deadheading will promote continuous blooming and encourage the growth of fresh buds. This practice can extend the flowering period as long as 6 weeks into midsummer.
  • Harvest flowers for indoor arrangements when they first open. Click here to learn more about harvesting flowers.
