It has strong adaptability and grows best on fertile sandy loam. Potted plants can be mixed with humus soil and the same amount of garden soil, and a small amount of compound fertilizer or bone meal and bean cake can be added. Pots should be deep and large, and short varieties should be selected, with 1 ~ 2 plants per pot; Generally, sufficient base fertilizer is applied before planting, and topdressing is performed once after four leaves are grown, and topdressing is performed once every half month with compound liquid fertilizer of nitrogen, phosphorus and potassium; Stop applying fertilizer before flowering, and then combine pruning and topdressing after flowering.

(2) Moisture

Afraid of drought and humidity. Potted plants should be kept moist during the growth period, and it is advisable not to accumulate water. During the dormant period, the basin soil should be a little dry. /kloc-control watering after 0/0 months. Water is not allowed before root digging 1 week, so the soil will be loose and dry.

(3) illumination and temperature

I like warmth and sunshine, but I'm afraid of cold. The growth and flowering temperature is 15 ~ 30℃, and the lowest growth temperature is 10℃. In case of frost, the leaves turn black and wither, and the roots below 0℃ are frozen. When potted, the first frost moved indoors. In the area north of the Yangtze River, after the frost leaves turn black, the above-ground parts should be cut off, dug up with roots and soil or aired for 2 days. When the root bark is dry and the sand is buried in semi-dry sand, it should be wintered indoors in the dark at 5 ~ 7℃. Divide the roots in spring, leave 2 ~ 3 buds in each cluster, plant them in flowerpots or open spaces in the sun, and leave leaves in about 30 days. Rootstocks do not need to be dormant, but germinate and propagate indoors at 20 ~ 25℃.

(4) shaping and pruning

Cut off the residual flowers in time after the flowers. In order to promote the germination of new branches, cut off the stems and leaves before entering the house in winter. Potted plants should be turned over once a year to remove old roots.

(5) Reproduction

Multiplication by ramets is the main method. Usually from March to April. Dig out the old rhizome, cut it into blocks, leave 2 ~ 3 buds with roots on each rhizome, plant it in the soil to a depth of 10 cm, keep the spacing between plants at 40 ~ 50 cm, and pour enough water. When cultivating new varieties or propagating in large quantities, sowing method can be used for propagation.
