Cultivation
Cotula coronopifolia, also known as Brass Buttons, is an easy-to-grow plant that can thrive in different types of soil. It requires full sun to partial shade and usually grows up to 6 inches. The best time to plant this plant is in the late spring season once the frost has passed. Ensure you loosen the soil and add organic matter before planting to enhance the soil's fertility.
The plant grows through self-seeding and can spread quickly if not controlled. You need to thin them out or transplant them regularly to maintain their size and shape. It's best to plant them around stones, rock gardens, or in containers to control their growth and offer a decorative visual effect.
Watering Needs
Cotula coronopifolia's watering needs vary depending on the season, temperature, and soil moisture retention. It can withstand periods of drought due to its succulent characteristics. However, it would be best to water the plant once or twice a week during the summer season to avoid the soil drying out, as it can cause the plant to die off.
It's best to water the plant at its base, either early in the morning or late in the evening, as it minimizes water evaporation and allows for efficient absorption.
Fertilization
Cotula coronopifolia does not require much fertilization. However, adding a balanced fertilizer, such as 10-10-10, during the growing season can enhance its growth and foliage. It would be best to apply the fertilizer once a month, following the manufacturer's instructions, to avoid over-fertilization, which can cause leaf burn or distortion.
It would be best to avoid fertilizing the plant during the winter season when the plant is dormant.
Pruning
Cotula coronopifolia requires minimal pruning. If the plant becomes too large for your space or gets out of control and needs reshaping, trim off the extra growth with a sharp and clean pair of garden shears.
Deadheading the plant after it blooms can help encourage more blossoms, keeping your plant looking neat and fresh. It would be best to prune the plant in the early spring season before the new growth starts to appear.
