Ecological habits of Arundo Donax

Arundo donax is often found near rivers, ponds and lakeside, and often grows in large areas to form reed beds. Arundo donax has warm light, moisture resistance and cold resistance. In the north, they need to be protected over the winter.

Arundo Donax propagation

Arundo donax can be propagated by sowing, splitting and cutting, and generally by splitting.

In early spring, cut the plant into clusters with 4 ~ 5 buds and then transplant them. Cuttings can be used to cut Arundo Donax stems into 20 to 30 cm segments in spring. Each cutting should have internodes, which are inserted into the wet soil. About 30 days later, white tender roots will sprout at the internodes and then be planted.

Rhizome cut propagation

Dig underground stems, wash soil and old roots, cut them into blocks with a sharp knife, and reproduce with 3-4 buds per block. The method of planting is according to the requirements of landscaping, the general plant row spacing of about 40cm, planting into a variety of geometric patterns is appropriate. In the early stages of planting water levels should be kept shallow, in order to improve soil temperature, water temperature, to promote the growth of plants. This period should clear weeds in time, in case the plant contend for nutrition, and affect the growth and development of the plant.

Cutting propagation

After cutting the Arundo donax, it should not leave the water. The water level of the bed and pool should be 3-5cm, and the roots can be taken about 20d. The main purpose of this method is to provide seedling material for next year's potting. Open cultivation, can choose the edge of the pond, the edge of the fake rock mountain and the low-lying water in the hole cultivation; Potted, choose 50-60cm inner diameter, do not leak pot is appropriate, after planting to keep the pot moist or shallow water. In the growing season, weeds should be removed in time so as not to compete with seedlings for nutrients. When the temperature reaches 42℃ in the hot summer in Wuhan and the middle and lower reaches of the Yangtze River, the foliage should be sprayed with water to prevent sunburn of the leaves.In the growing season, fertilizer should be applied once or twice to improve the growth and development ability of the plant and its ornamental value.
