White chrysanthemum has no strict requirement on soil (many plants grow strongly, but this is in natural state. Once the family plants are potted, we need to say otherwise), we should choose fertile, loose and moist sandy soil. The permeability of the soil must be good. In the growth process of the white chrysanthemum, it is necessary to ensure that the soil is moist without water accumulation.
The white crystal chrysanthemum likes the sunny but relatively cool environment. The lack of sunshine will affect the flowering and cause the flowers to wither in advance. Family maintenance, it is good to put it on the south balcony!
The most suitable temperature for its growth is 15 ~ 25 ℃. It can survive the winter safely when it is lower than - 5 ℃, and it can not grow well when it is higher than 30 ℃. Therefore, in winter, it is necessary to control the temperature above 0 ℃, if the environment is lower than - 5 ℃ for a long time, the leaves will be frostbitten, dry and yellow, but with the temperature rising, they will gradually recover without affecting the growth. High temperature in summer will speed up the withering of flowers. It is necessary to put them in a cool and ventilated place to prolong the flowering period.
It is the most important to maintain the flowering period of the chrysanthemum, because the chrysanthemum has a long flowering period, which can bloom from the winter solstice to the beginning of summer, and the flowering period is from March to may, during which it needs more nutrients. Fertilize once every 20-30 days in the flowering period, once every half a month in the growth period. Do not water too frequently. Water once every 7-10 days to keep the soil moist.
The common diseases are leaf spot and stem rot, which can be sprayed with 65% zineb wettable powder. Insect damage is caused by bug and leaf miner, which can be killed by spraying 25% carbaryl wettable powder 1500 times.
Spring and autumn is the best season for planting. In hot summer or cold winter, it is better to plant indoors. If the indoor temperature is lower than 15 or higher than 35 ℃, it is recommended to wait patiently until the appropriate season before planting.
