Peony is a deep-rooted deciduous shrub flower, which is hi-sun, cold-resistant and cool-loving. It avoids high temperature and heat, and is suitable for growth in loose, fertile, well-drained sandy soil. Therefore, it is advisable to use a mixed soil of sand and cake fertilizer for the potted soil of cultivated peony, or a culture soil mixed in a ratio of 1:1:1 with fully decomposed manure, garden soil, and coarse sand. If the cultivated soil contains too much water, its fleshy roots will rot. Therefore, in the event of continuous rain, it is necessary to drain water in time and must not allow water to accumulate in its roots. Peony is not tolerant to high temperatures, and it is necessary to take cooling measures in time when it is hot in summer. It is best to use a arbor for shade. Cover with straw or reeds before noon and leave it in the evening. This measure can be done in time to prevent falling leaves. If it is allowed to heat and defoliate, it will seriously affect flowering. Because of its longer roots and larger plants, peony is suitable for planting. For potting, large, well-pervious tile basins should be selected, and the depth of pots should be 30 cm or more. It is best to use a tile cylinder with a depth of 60-70 cm. The reproduction of peony can be done by sowing method, ramets method or grafting method. However, the sowing time is too long. From the time of sowing, it takes 4-5 years to see the flowers.
The common diseases of peony are brown spot, root rot and scale insects. Brown spots or brown spots appear on the leaves of the brown spot, which can be sprayed 1-2 times per month with Bordeaux mixture. If the disease is severe, it can be sprayed 3 times. The leaves that are seriously affected should be cut and burned to prevent the spread. If root rot is found, cut the root of the disease and burn it, and sprinkle some sulfur powder in the planting hole when planting. Scale insects sprayed with 40% omethoate emulsion plus 1500-fold aqueous solution had better results.
