Light Requirements
Chrysanthemum coronarium spatiosum requires full sun or partial shade to grow. They prefer bright sunlight for about six hours a day. In areas with intense heat, partial shade may be necessary.
Temperature Requirements
The plants can grow in a wide range of temperatures, but they prefer moderate temperatures between 60 to 70°F (15 to 21°C). However, they can also survive in temperatures as low as 20°F (-7°C) and as high as 90°F (32°C). They are typically planted in the spring and can survive mild frosts.
Soil Requirements
The plants grow well in well-draining soil with a neutral pH between 6.0 to 7.5. They can tolerate a wide range of soil conditions, including poor or clay soil. The ideal soil contains a good amount of organic matter, like compost or aged manure, to help retain moisture and nutrients.
Cultivation
Chrysanthemum coronarium spatiosum, also known as Garland chrysanthemum, can grow well in mild to warm temperatures. Since they are cold-tolerant, they can withstand frost and snow up to a certain extent. They grow best in well-drained soil with a pH of between 6.0 and 7.0. Plant the seeds in 1/4 inch deep holes, place them 12 to 15 inches apart, and maintain a temperature of 68°F to 77°F to ensure proper germination. Keep the seedlings moist for the first few weeks and ensure proper sunlight exposure for good growth.
Watering Needs
Chrysanthemum coronarium spatiosum requires moderate watering. Water the plants deeply, at least 1 inch of water per week, and keep the soil moist but not waterlogged. In dry and hot climates, increase the watering frequency and duration. Always check the soil moisture level before watering again to avoid overwatering, which can lead to rotting of the roots and yellowing of the leaves.
Fertilization
Apply a balanced fertilizer, such as 10-10-10 or 20-20-20, every 4 to 6 weeks during the growing season. Do not over-fertilize as it can result in excessive vegetative growth, reduced flowering, and increased susceptibility to disease. Mulching the soil around the plants can also help improve soil fertility, conserve moisture, and suppress weed growth.
Pruning
Chrysanthemum coronarium spatiosum requires regular pruning to encourage bushy growth and to maintain a compact shape. Pinch off the top two to three inches of new growth in early summer and again in mid-summer as this will promote branching and encourage more flowers. Deadheading, or removing spent flowers, will also encourage continuous blooming and prevent seed production. In the fall, after the first frost, cut the stems down to the ground level to prepare for winter dormancy.
Propagation of Chrysanthemum coronarium spatiosum
Chrysanthemum coronarium spatiosum, commonly known as Crown Daisy, is a plant species in the family Asteraceae. It is native to the Mediterranean region, but it is now widely cultivated in different parts of the world for its edible and ornamental value.
Propagation Methods
Chrysanthemum coronarium spatiosum can be propagated through seeds or vegetative means, such as cuttings and division.
Propagation from Seeds
The seeds of Chrysanthemum coronarium spatiosum can be sown directly in the garden or started indoors before transplant. The best time to plant the seeds is in early spring or early autumn. Sow the seeds about ¼ inch deep and 6 inches apart in well-draining soil. Keep the soil moist until the seedlings emerge, and then thin them to about 12 inches apart.
Propagation from Cuttings
Cuttings are a fast and easy way to propagate Chrysanthemum coronarium spatiosum. Take a cutting from a healthy plant during the spring or summer months, making sure it is at least 6 inches long and has several leaves on it. Remove the lower leaves and dip the cutting in a rooting hormone. Insert the cutting into a pot filled with a well-draining potting mix. Keep the soil moist and place the pot in a warm and bright location until roots develop.
Propagation from Division
Division is a way to propagate Chrysanthemum coronarium spatiosum without using seeds or cuttings. This method is best done in early spring or early autumn when the plant is not actively growing. Dig up the plant and divide the root ball into several sections, making sure each section has some roots and shoots. Replant the divisions in well-draining soil, water them thoroughly, and keep the soil moist until new growth appears.
By using any of these propagation methods, you can grow more Chrysanthemum coronarium spatiosum plants and enjoy their beautiful flowers or edible leaves.
