Celery peony is a very beautiful flower, the flower shape is like a peony, rich in color, and the flower posture is charming. Its growth cycle is that it grows in winter, blooms in spring, and dormants in summer. In addition to the variety, the ornamental value of celery peony depends largely on the factors of cultivation management. A good quality potted celery leaf peony should be lush in clusters, compact and short in plant type, dark green and short in leaf color, large and colorful flowers, high double petal rate, and the flowers should not grow too high in leaf clusters. Let's take a look at what to pay attention to if you want to raise celery leaf peony.
First of all, we need to know that celery peony can be sown and reproduced, and can also be propagated by roots, with a large sowing reproduction coefficient, a high hybridization rate of seeds, and a large variability of seedlings, it is difficult to ensure the excellent characteristics of the female parent, and if you want to maintain the characteristics of the female parent, you must take the root propagation by tube.
Celery peony likes a cool and ventilated environment, so the cultivation is generally in the autumn after the cool, the root tuber is planted and planted, the growth process of the demand for water is many, the lack of water during the growth period will lead to the plant dwarf, small leaves, tillers are also less, the root system is not developed, the flowering is less, the flowers are small, the double petal rate is low, the later water-deficient plants will be forced to dormant, and the leaf yellowing tuber root quality is poor. However, as a root flower, there is also a danger of root rot with too much moisture. The amount of water must also be balanced, as excessive drought or water staining can seriously affect growth. The general law of watering during the growth process is as follows: a certain amount of water is required at the beginning of growth, reaching the maximum at the beginning of sprouting, and gradually decreasing later.
Celery peony is not resistant to high temperatures, so the environment should be cool and ventilated, and the light should be sufficient, as insufficient light will cause the plant to grow long, the flowers are small and the flower color is dull.
Celery leaf peony grows faster, planting the foot fertilizer, is the key to cultivating strong seedlings, when the planted root bud is sufficient, after the leaf unfolds, you can apply some nitrogen fertilizer-based fertilizer to promote the growth of the tree, in the center of the leaf bud appears with a concentration of 100-120ppm paclobutrazol foliar spray, in order to prevent the flower stem from growing too much to affect the ornamental value.
When potting celery peony, the use of paclobutrazol is a very important measure. It is also an important means to ensure the quality of celery peony potted flowers.
