What To Know

  • Spread a layer of mulch, such as straw or bark chips, around the base of the plants to retain moisture, suppress weeds, and regulate soil temperature.
  • Cut the stems close to the base and place them in a vase with fresh water.
  • Plant the cosmos so that the top of the root ball is level with the soil surface.

Bare root cosmos, with their vibrant colors and cheerful disposition, are a beloved addition to any garden. These easy-to-grow annuals offer a profusion of blooms from summer to fall, adding a touch of cosmic beauty to your outdoor space. Planting bare root cosmos is a straightforward process that can be mastered with a few simple steps.

Materials You’ll Need:

  • Bare root cosmos plants
  • Compost or manure
  • Garden trowel
  • Watering can

Step 1: Soil Preparation

Prepare the soil by amending it with compost or manure to improve drainage and fertility. Cosmos prefer well-drained, loamy soil with a pH between 6.0 and 7.0.

Step 2: Digging Holes

Dig holes that are twice the width of the root ball and deep enough to accommodate the entire root system. Space the holes 12-18 inches apart to allow for proper air circulation and growth.

Step 3: Plant the Cosmos

Gently remove the cosmos plants from their packaging and inspect the roots. Trim any damaged or broken roots. Place the plants in the prepared holes and spread the roots out evenly.

Step 4: Fill the Holes

Backfill the holes with soil, pressing gently around the base of the plants to remove any air pockets. Water thoroughly to settle the soil around the roots.

Step 5: Mulching

Spread a layer of mulch, such as straw or bark chips, around the base of the plants to retain moisture, suppress weeds, and regulate soil temperature.

Step 6: Fertilizing

Fertilize the cosmos plants every 4-6 weeks with a balanced fertilizer. Avoid over-fertilizing, as this can lead to leggy growth and fewer blooms.

Step 7: Deadheading

Deadhead spent blooms regularly to encourage continuous flowering throughout the season. Simply pinch off the faded flowers at the base of the stem.

Care and Maintenance

Cosmos are relatively low-maintenance plants but require regular watering, especially during hot and dry weather. Water deeply at the base of the plants, avoiding the foliage. Avoid overwatering, as this can lead to root rot.

Pests and Diseases

Cosmos are generally pest-free and disease-resistant. However, they may occasionally be affected by aphids, thrips, or spider mites. Treat infestations promptly with insecticidal soap or neem oil.

Companion Planting

Cosmos make excellent companion plants for tomatoes, peppers, and carrots. They attract beneficial insects that help control pests and improve pollination.

Harvesting Cosmos

Cosmos flowers can be harvested when they are fully open. Cut the stems close to the base and place them in a vase with fresh water. Cosmos blooms have a long vase life and will brighten your home for several days.

The Cosmos in Mythology and Folklore

Cosmos, with their vibrant colors and cheerful disposition, have been associated with positivity, joy, and love since ancient times. In Aztec mythology, cosmos were believed to represent the sun and were often used in religious ceremonies.
