How much is the dragon blood tree in Xuzhou for 3 years?

Here is a brief introduction of this flower.

Dragon blood tree:

Other names are Mule Brawly, Dracaena angustifolia and Dracaena elongata.

Family belongs to Liliaceae, Dracaena.

Dracaena is native to southern China and tropical Asia, while other species are distributed in tropical Africa.

Morphological characteristics: evergreen shrub, with sessile leaves, dense top of stem, thick paper, wide strip or oblanceolate, length 10~35cm, width 1 ~ 5.5 cm, narrow near the base, and obvious ribs at the lower part of midvein, belonging to many varieties for garden viewing.

Habit-cultivation and maintenance: like light, full of light, bright leaves. Not cold-tolerant, the winter temperature is about 15C, which is too low. Due to insufficient water absorption by the root system, yellow-brown patches will appear at the tip and edge of leaves, and it prefers loose, well-drained soil with rich humus. Humus soil, peat soil and river sand can all be used as mixed substrates, and the tip of the blade is not easy to dry. Some plants damaged by indoor decoration can be recovered as long as they are moved back to the production site for a period of time if the damage is not serious, while some seriously damaged plants are difficult to recover and can be used for seedling propagation; For example, it is a pity that some people throw away their leaves after they have been damaged for a while. In fact, as long as the residual branches are cut off about 2cm below the budding branches at the upper end of the stem and the routine management is continued, new branches and leaves can sprout after a period of time.
