Colorful Dianthus is a very beautiful flowering plant, also known as American Dianthus or Feathery Dianthus, and it is one of the famous traditional flowers in China. Although colorful Dianthus belongs to the Caryophyllaceae family, it can bloom too! So, how should such beautiful colorful Dianthus be planted? Let's find out together with the editor!
How to plant colorful Dianthus
1. Soil: Dianthus requires fertile, loose, well-drained soil with lime content or sandy loam, prefers alkaline soil, and can use a mixture of garden soil (6 parts), compost (2 parts), and sandy soil (2 parts) as the growing medium.
2. Watering: Keep the potting soil moist during the growth and development of Dianthus, as excessive watering can cause root rot.
3. Sunlight: Dianthus requires ample light during its growing period, and should be placed in a sunny location. In summer, scattered light is preferred to avoid direct sunlight. High temperatures require shading and cooling.
4. Temperature: The optimal growing temperature for Dianthus is between 15-20℃. In winter, it should be placed in a greenhouse with a temperature maintained above 12℃.
Planting methods and precautions for colorful Dianthus
1. Colorful Dianthus is commonly planted using cuttings, inserting the cuttings into flower pots, breeding trays, or mixed cutting propagation soil and keeping it moist.
2. Under normal conditions, roots will form within three weeks, with coconut fiber mixed growing medium being the best. After the cuttings take root, pinch the main bud to promote new growth, with the morning being the best time for pinching.
3. Colorful Dianthus prefers sunlight and well-drained soil. You can create a suitable growing environment by mixing coarse sand into clay or raising the ridges. The louder the squeaking sound when holding sand in your hand, the better the soil quality.
4. Regular pruning of flower branches can promote continuous blooming. Simply cutting off the faded flower heads is not enough; the entire flower branch should be cut to promote suckering from the root.
5. During the growing season, dilute and apply a phosphorus-rich tomato fertilizer every two weeks.
6. To make colorful Dianthus bloom profusely, they should be pruned short in early September to form dense flower mounds.
7. Precautions: Colorful Dianthus has varying water requirements. In spring and autumn, when the weather is dry, more water can be added. In summer, with the hot weather and fast evaporation, frequent watering is needed. However, due to excessive rainfall during the plum rain season, timely drainage and loosening of the soil are necessary. Additionally, in winter, to avoid frost damage, less watering is required.
The sowing time for colorful Dianthus
Some flower enthusiasts want to grow colorful Dianthus but don't know when to sow it. In fact, the sowing time for colorful Dianthus varies by region. Flower enthusiasts need to know that the optimal germination temperature for Dianthus seeds is 21℃-22℃, but this temperature is not an absolute value.
Sowing is not just for germination but also for subsequent care issues. Colorful Dianthus is cold-tolerant but not heat-tolerant. If sown in spring and summer, it may be difficult to survive the summer because many places are very hot. The relatively ideal sowing months are September to December, as many flower enthusiasts now sow on balconies and have breeding boxes, allowing them to control the temperature. This way, there is no need to worry about the colorful Dianthus surviving the summer.
Although winter sowing can create germination temperatures, the lighting in many flower enthusiasts' homes is not very abundant, which may cause seedlings to grow tall. Therefore, when sowing colorful Dianthus, consider temperature, light, and post-planting care comprehensively.
The above is a comprehensive explanation of when colorful Dianthus blooms, planting methods, and timing, hoping it can help you.
