Matters needing attention in the culture of white chrysanthemum

1. Soil

Potted white crystal chrysanthemum is best to use loose, fertile sandy soil, its air permeability is good, more conducive to plant growth.

two。 Temperature

The suitable temperature for the growth of Chrysanthemum morifolium is 15 ℃-25 ℃, cold-tolerant, but not heat-resistant. If it is lower than-5 ℃, it will frostbite the leaves, but the increase of temperature will not affect the growth, but if the environment is higher than 30 ℃, it will accelerate the flower withering. So potted white chrysanthemum should be in a cool environment.

3. Light

White crystal chrysanthemum also needs the care of the sun, the right amount of light will make the flowers more colorful, potted white crystal chrysanthemum can be placed on the south balcony.

4. Water and fertilizer

White crystal chrysanthemum has a long flowering period, so it needs a lot of nutrients, topdressing once a month during flowering, but white crystal chrysanthemum can not be watered frequently, once a week to keep the soil moist.

Soil selection

White chrysanthemum is not strict with the soil (many plants are very strong, but this is a natural state, once the family pot planting, it is necessary to say otherwise), choose fertile, loose, moist sandy soil. The air permeability of the soil must be good, in the process of white crystal chrysanthemum growth, it is necessary to ensure that the soil is moist without stagnant water.

Light and temperature requirements

White chrysanthemum likes sunny but relatively cool environment, lack of sunlight will affect flowering, causing flowers to wither ahead of time. Family care, put it on the south balcony as well!

White crystal chrysanthemum is cold-tolerant, but not resistant to high temperature. the most suitable temperature for growth is 15-25 ℃. If it is below-5 ℃, it can survive the winter safely. If it is higher than 30 ℃, the plant will grow badly. So in winter, the temperature should be controlled above 0 ℃. If the environment is lower than-5 ℃ for a long time, the leaves will be frostbitten, dry and yellowed, but with the increase of temperature, the growth will not be affected gradually. The high temperature in summer will speed up the withering of the flowers. Put them in a cool and ventilated place to prolong the flowering period.

Water and fertilizer requirements

The maintenance of the flowering period of Baijing chrysanthemum is the most important, because the flowering period is longer, it can bloom from winter to early summer, and the full flowering period is from March to May, during which more nutrients are needed. Topdressing every 20-30 days during flowering, topdressing every half a month during the growing period, watering not too frequently, watering once every 7-10 days to keep the soil moist.

Control of diseases and insect pests

The common diseases are leaf spot and stem rot, which can be sprayed with 65% Daimen zinc wettable powder. Insect pests are harmful to blind bugs and leaf miners, which can be sprayed 1500 times with 25% carbaryl wettable powder.

Sowing at the right time

Spring and autumn are the most suitable for planting. It is best to sow seeds indoors in extreme summer or cold winter. if the indoor temperature is below 15 or higher than 35 degrees Celsius, it is recommended to wait until the right season before planting.

Culture methods and matters needing attention of Chrysanthemum morifolium

White crystal chrysanthemum is low and strong, with many flowers and long florescence, so it is suitable for planting and potted plants. Then how to raise white chrysanthemum? Then Xiaoqi shared the breeding methods and matters needing attention of white chrysanthemum.

I. Culture methods of Chrysanthemum morifolium

Chrysanthemum morifolium is usually propagated by sowing, usually sowing from September to October in autumn, and the suitable temperature for germination is 15 ℃ to 20 ℃. Mix the seeds with a small amount of fine sand or culture soil and sow them in the seedling bed or seedling tray. It is appropriate to cover the soil with no seeds. After sowing, the seeds should be shaded by Reed curtains, not covered with thin film, kept moist, and germinated for 5 to 8 days.

White chrysanthemum seedlings after a little topdressing, to promote the seedlings to grow strong, grow two or three leaves for the first time, bare roots without persistent soil. Grow 4 to 5 true leaves and then transfer them to a seedbed or nutrition bowl for cultivation.

Watering once at the end of October, when the border soil is not sticky and not scattered, the chrysanthemum can survive the winter. although the white crystal chrysanthemum is cold-resistant, the seedlings had better be placed in a plastic greenhouse or cold room in winter, so that it can continue to grow, timely watering and fertilization, timely removal of flower buds and increasing crown diameter, and moving into outdoor or flower beds in the early spring of the next year can increase its ornamental effect. Like warm, more cold-resistant, like light, but also resistant to half-shade, the growth temperature is 15-25 degrees.

II. Matters needing attention in the culture of white chrysanthemum

White chrysanthemum is not strict on soil, but it grows best in well-ventilated, fertile and moist loam or sandy loam. White chrysanthemum needs to keep the soil moist during its growth.

White crystal chrysanthemum likes the sunny and cool environment, lack of light and poor flowering. Avoid high temperature and humidity, flowers wither faster with the increase of temperature in summer, and grow poorly above 30 ℃. Putting them in a cool and ventilated environment can prolong the flowering period.

Watering every 7-10 days, no need to fertilize too frequently. During the growing period, N, P, K compound fertilizer was applied every half a month, the proportion was 2 ∶ 1 ∶ 2, or thin fecal water. After the white chrysanthemum blossoms in February, stop fertilizing.

The above is the introduction of white crystal chrysanthemum culture methods and matters needing attention. White crystal chrysanthemum blossoms poorly under hot conditions and is easy to die, so we should pay special attention to it.
