Watering Cockscomb
As summer temperatures rise, Cockscomb plants require frequent and abundant watering. Nonetheless, keep in mind that proper soil drainage is essential.
Excessive watering and soggy soil can lead to root rot or fungal diseases. To prevent fungal diseases, try to avoid wetting the leaves and the flowers. Ideally, you should water this plant directly at its base.
Propagating Cockscomb
Since this plant produces an abundance of seeds, it is relatively easy to grow it from seed. To make sure that the plant will grow in the summer, you should plant the seeds in May.
You should sow the Cockscomb seeds on a warm seed tray. Barely press the seeds in the medium. Keep the soil moist, at an average temperature of 23 degrees. The seedlings should emerge in about 10 days.
When this happens, move the tray to a very sunny location. If you do not have sufficient natural light indoors, use a led grow light.
The seedlings should receive 16 hours of light per day. Keep in mind that a dark period is also necessary for growth, so do not leave the lights on non-stop.

When the seedlings grow two leaves each, you will want to thin them and leave one seedling for each cell in the seed tray. You can start fertilizing when the seedlings are about a month old. Around the end of May or the beginning of June, you should have some healthy young plants that you can transplant to a permanent location.
You can also propagate Celosia cristata through cuttings that catch roots quite easily. You can place the cuttings directly in their final containers, or outdoors if the weather is favorable. It will take about three to four weeks for the cuttings to catch some healthy roots.
Outdoor Cockscomb plants will spread on their own, and in the right environments, they can become a little invasive. You might want to keep an eye on them to prevent them from invading the territory of other plants. But, if you want them to produce seeds, leave a few blooms at the end of the season.
Conclusion
If you want to enrich your garden with some vibrant crimson or yellow shades, you cannot go wrong with Cockscomb. Moreover, it pays to have a potent pharmaceutical herb in your garden, especially one that you can also use as a vegetable. You can grow the plant directly in the garden or in containers on your patio.
Since this is a low-growing plant, you can also use it as an edging in containers. It grows well with other annuals such as Marigold or Amaranth. You can use it to make some amazing dry wreaths that will embellish your front door for months to come.
