This plant is highly resilient to cold, drought, barren soil, and extreme heat. At -8 degrees Celsius, its leaves remain green. It can survive winter at -32 degrees. On barren sandy land, it can grow even without rain for several days. It can withstand temperatures of up to 42 degrees Celsius. It blooms twice a year, with each flowering lasting about 40 days.

The propagation of Dianthus superbus primarily involves cuttings and branching. Cuttings can be propagated from May to July. Select healthy plants and use semi-woody stems, 7 to 25 cm in length, as the cuttings. The cutting medium can be clean river sand or vermiculite.

Propagation by division can be carried out in spring and autumn. Dig up seedlings, separate the plants with entangled roots to form individual seedlings, and plant them with a spacing of 15 to 20 centimeters between each plant. Up to two or three plants can be planted in each hole.

After planting the flower, compact the soil, pour root-binding water, and then repeat after 3 days. Approximately 4 days later, the soil can be loosened once and then transitioned to regular management. Apply amino acid water-soluble fertilizer to fertile farmland, and top dress appropriately to supplement nutrients.
