To encourage more flowers to bloom, deadhead the spent blooms throughout its growing season. If allowed to go to seed, these plants will readily reseed themselves, producing plenty of flowers the following year. To prevent this, simply trim away spent blooms before they go to seed. Cockscomb is resistant to pests and most diseases, though fungal diseases can be an issue.
Light
Full sun will encourage plentiful growth of cockscomb. These plants can tolerate some shade, but shaded areas can harbor too much moisture and contribute to fungus or rot. At least 8 hours of direct sunlight will keep these plants healthy.
Soil
Cockscomb thrives in rich, nutrient-dense soil conditions and prefers neutral to slightly acidic pH levels. Well-draining soil is essential since it helps to ward off issues with fungal diseases.
Water
A regular watering schedule will keep these plants healthy, as they prefer evenly moist soil. However, be sure not to overwater. To avoid this, water once the top inch or two of the soil feels dry. Water at the base of the plant to avoid getting the leaves wet.
Temperature and Humidity
Cockscomb thrives in warm climates but can still be planted as an annual in areas with cold winters. In zones 9-11, it can be kept as a perennial. This plant can withstand both low and high humidity levels.
Fertilizer
Before planting a cockscomb plant, amend the soil with compost. This will enrich the soil with needed nutrients as well as help the soil drain excess water. During its growing season, apply liquid fertilizer monthly to support blooming.
Propagating Cockscomb
Propagate cockscomb by means of cuttings:
How to Grow Cockscomb from Seed
When growing cockscomb from seeds, be sure to start the seeds around 8 to 10 weeks before your last frost date for planting. For cold climates where this plant grows as an annual, seed starting will need to be done indoors. For warm climates, this can be done directly in the garden. Here’s how:
Potting and Repotting Cockscomb
Because of this plant’s compact size, cockscomb is a good option for adding bursts of color on patios or in container gardens. Just be sure the pot has good drainage holes to prevent an accumulation of too much moisture. These plants should not need repotting very often, and it is best to avoid it. Cockscomb does not handle transplanting or changes in its environment very well, so leaving it in its pot unless absolutely necessary will spare this plant from additional stress. If you must repot, gently remove the plant and try not to disturb the root system. Place in a large pot and fill it in with rich, well-draining potting soil, not garden soil, as potting soil drains better. Be sure to bury the plant at the same depth as before.
Overwintering
The cockscomb cannot handle cold temperatures and is kept as an annual in areas with cold winters. If kept in a container, cockscomb can be brought indoors during the winter if it is provided with enough light. For areas with warm winters, no extra care is required for outdoor plants as cockscomb thrives in warm temperatures.
