How to plant the graceful Persian chrysanthemum?

Persia chrysanthemum sounds like a beautiful plant. Originated from Mexico and other parts of South America. Sexual preference for warm and cool climate, avoid extreme heat, not resistant to cold, for sunny plants. The optimum temperature for growth is 10C~25C and blossoms under short-day conditions. So what is the planting method of Persian chrysanthemum? Next, the editor of Tuliu.com will take a look at it.

I. Propagation by sowing

1. The seeds can be sowed in autumn, winter and early spring in greenhouse, and the optimum temperature for germination is 18C~25C. Can be direct seeded, after the seedling, and then inter-seedling, transplanting. You can also raise seedlings and then plant flower beds. Spring sowing should not be too late, so as not to blossom easily in the hot summer. It takes about 4050 days from sowing to flowering. The seed setting rate of this plant is high. After the seeds are ripe, the fruits are easily scattered around and reproduce on their own.

2. In areas with warm climate, the flowering period can be from late autumn to spring. This plant can also be propagated by cuttings, and robust branches are usually selected for cutting in early summer. The seed setting rate of double petal varieties is poor, so they can be propagated by cutting. Because the stem of the plant is not strong enough, the plant is easy to lodge after heavy wind and rain, so a bracket can be set up to prevent lodging. Picking the heart in late spring and early summer to promote more branches of the plant and control the height of growth is also a good measure to make the plant short and strong to prevent lodging.

2. Fertilizing and medicating

Persian chrysanthemum belongs to short-sunshine flowers, so it blossoms later in spring sowing, with higher height, plump plant type and strong vegetative growth, but it is prone to lodging. In order to solve this problem, when the new bud grows to 3 cm after coring, it can spray paclobutrazol 300 mg / L for the first time, and then spray it every 7-10 days for 3 times, which can play an obvious dwarfing effect.

3. Planting density

As autumn sowing is generally carried out in August, which is suitable for the high temperature and rainy season, the harm of diseases and insect pests will cause certain difficulties to the subsequent cultivation and management. Therefore, the density of Persian chrysanthemum sowing should not be too high, and time seedlings should be used to improve ventilation and light transmission conditions. In addition, insecticides and fungicides can be sprayed regularly. 70% chlorothalonil is mixed with 1000 times of Nongdile, once every 15 days, which can play a good preventive role. Because of the short vegetative growth and early flowering in autumn, it can blossom one month after sowing, but the growth potential is poor and the plant type is thin, so some compound fertilizer should be applied as far as possible before flowering.

4. Proper pruning

After blooming, the height of Persian chrysanthemum is more than 1 meter, and the lateral branches have strong germinating power, so it is easy to cause lower baldness due to poor ventilation and light transmission. After seeding, the upper part is heavy and lodging is easy to occur. After lodging, it not only loses its ornamental value, but also is prone to rot. In order to solve this contradiction, the pruning method is often adopted, that is, the upper part is cut off 10 centimeters from the ground and watered again, preferably covered with a sunshade net, and then removed after sprouting, as long as the management of water and fertilizer is strengthened, it only takes more than a month.

All right, the above is the planting method of Persian chrysanthemum brought by the editor of Tuliu.com. I hope you like it. I'll see you next time.
