Cosmos Seeds: Detailed Care Guide
-
Seeding:
- Cosmos seeds can be sown directly outdoors after the last frost or started indoors 4-6 weeks earlier.
- Plant the seeds about ¼ inch deep in well-drained soil.
- Space seeds 12-18 inches apart to allow for their bushy growth.
- Germination usually occurs within 7-10 days.
-
Growing:
- Cosmos plants grow best in full sun, requiring at least 6 hours of sunlight per day.
- They can grow quite tall, ranging from 1.5 to 6 feet, depending on the variety.
- Thin seedlings when they are about 3-4 inches tall to avoid overcrowding, promoting better air circulation.
- Cosmos plants are tolerant of poor soil and often do better in less fertile conditions, as rich soil may cause fewer blooms.
-
Care:
- Cosmos are easy to grow and require minimal maintenance.
- Deadheading (removing spent flowers) encourages continuous blooming throughout the summer and into the fall.
- These plants are relatively pest-free, but occasionally you may notice aphids or spider mites. Use insecticidal soap if necessary.
- Cosmos can self-seed, so you may find new plants growing in the same spot the following year.
-
Temperature:
- Cosmos thrive in warm temperatures, ideally between 65°F and 85°F (18°C to 29°C).
- They are sensitive to frost, so do not plant them outdoors until all danger of frost has passed.
-
Watering:
- Cosmos are drought-tolerant and prefer well-drained soil, so water them sparingly.
- Water deeply but infrequently, allowing the soil to dry out between waterings.
- Avoid overwatering, as soggy soil can lead to root rot. In most cases, once a week watering is sufficient, but adjust based on weather conditions.
