The cultivated soil is preferably sandy loam with good drainage and ventilation, and the sunshine and half-day sunshine are ideal, and the shaded area is poorly fertile. After the high snow seedlings are planted, they must be topped once, which will promote multi-branch, dwarf plants, and more flowering; immediately after the topping, apply the decomposed organic fertilizer or three elements for topdressing, and then apply a small amount of three elements every 25 days. Times. Usually cultivate the soil to maintain the humidity, avoid the stagnant water, and the poor roots are perishable. Young plants that are spring sowing, the temperature in the growing season is getting higher and higher, and it is necessary to pay attention to prevent the heat from wilting, and if necessary, shading or temporarily shifting the potted plants to the shade. Plants are too long to be easily undulated and need to be supported by pillars.
Humidity management
Like the higher air humidity, the air humidity is too low, it will speed up the single flower withering. Also afraid of rain, keep the leaves dry at night. The optimum relative humidity of the air is 65 to 75%.
Temperature management
Like warm climate, avoid hot, obviously growing poorly in summer when the temperature is higher than 34 °C; not resistant to frost and cold, when the winter temperature is below 4 °C, it will go to sleep or die. The most suitable growth temperature is 15 to 25 °C. Usually planted in autumn and winter to avoid high temperatures in summer.
Lighting management
In the spring, summer and autumn, you need plenty of sunshine. When the temperature is high (the temperature is above 25 °C during the daytime), if it is kept under direct sunlight, the leaves will become significantly smaller, the branches will be shortened, the leaves will become yellow, fall off, grow very slowly or enter semi-dormant. status. After the flowering period is put indoors for a period of time (10 to 15 days), it must be moved to a place with shading (insulation) conditions for a period of time (about one month), so alternately exchanged to facilitate plant accumulation of nutrients. Continue to bloom.
Fertilizer management
Like other grasses, there are more requirements for fertilizer and water, but it is required to follow the principle of fertilization (water) with “light fertilizer, less quantity, less nutritionâ€, and after the fertilization, keep the leaves and flowers dry at night:
Spring and autumn
These two seasons are its growing season, and the management of fertilizer and water is in the order of “Huabao†– “Huabao†– Qingshui – “Huabao†– “Huabao†– clear water (at least weekly) Guarantee two "Huabao"), the interval period is about: 1 to 4 days for outdoor maintenance, the interval between sunny days or high temperature period is shorter, and the intervals between rainy days or low temperature periods are longer or not poured; ~ 6 days, the interval between sunny days or high temperature period is shorter, and the interval between rainy days or low temperature periods is longer or not.
Summer : During the high temperature period in summer, it often goes into a dormant state. It does not require much fertilizer or water, and even controls fertilizer to control water. The management of fertilizer and water follows the sequence of “Huabao†– Qingshui – Qingshui – “Huabao†– Qingshui – clear water. The interval period is about 3 to 5 days for outdoor maintenance, and the interval between sunny days and high temperature periods is shorter. The interval between the rainy days or the low temperature period is longer or not. The indoor maintenance period is 4 to 7 days. The interval between sunny days and high temperature periods is shorter, and the interval between rainy days or low temperature periods is longer or not. The watering time should be arranged as much as possible in the morning when the temperature is low, and keep the leaves dry at night. Also spray the plants often.
winter
In the winter dormancy period, the main thing is to control the fertilizer and control the water. The fertilizer and water management is cycled according to the “Huabao†– Qingshui – Qingshui – “Huabao†– Qingshui – clear water, with an interval of about 7 to 10 The interval between days, sunny days or high temperature periods is shorter, and the interval between rainy days or low temperature periods is longer or not. The watering time should be arranged as far as possible when the temperature is high at noon on a sunny day.
prune
Every two months, the branches with old leaves and yellow leaves are cut off, and as long as the temperature is suitable, they can bloom in all seasons.
