Pot culture should be mixed with 5 parts of rotten leaf soil, 4 parts of sandy loam and 1 part of rotten cake powder. Generally, it is advisable to change basin and soil once a year in spring.
During the growing period, thin liquid fertilizer combined with nitrogen and phosphorus can be applied every 10 days or so. If the nutrition is insufficient, it is difficult to bloom again after one flower.
Usually, the principle of "wet and dry" should be mastered when watering. In dry spring and hot summer, spray water on branches and leaves 1-2 times a day. Do not water too much to cause basin soil water. In winter, when the room temperature is low, it is necessary to strictly control watering and stop fertilization to prevent rotten roots. Loosen the soil timely after each fertilization and watering to facilitate ventilation.
Upside down Golden Bell likes cool climate, most afraid of high temperature, sun and rain in summer. When the temperature exceeds 30 ℃ in summer, the plant metabolism is slow and the growth is stagnant. At this time, it is easy to have fallen leaves, rotten roots and other phenomena. If effective measures are not taken in time, the whole plant will die.
In the indoor cultivation, if the ventilation is not good, the young stems and leaves are easily damaged by aphids and whiteflies. In case of occurrence, 200 times of Omethoate can be used for spray control.
It is often propagated by cutting and sowing.
(1) cutting method: it can be carried out all year round except summer dormancy period. It is better to cut in spring, with high and fast rooting survival rate. The vigorous shoots of the shoots are 7-8 centimeters long, with 2-3 knots, and the basal leaves are cut off. They are inserted in the sand bed. They are kept moist by spray, and can take root in about 10 days, and they can be served in 1 months.
(2) sowing method: it can be carried out in spring and autumn. In autumn, it can germinate in 15-20 ℃ for 15 days. The seedlings sown in spring can bloom in the second year.
First, to reduce temperature and increase humidity, the family potting can move the flowerpot to a cool place with ventilation and shelter from the rain, such as the place where the scattered light can be seen slightly under the north balcony or eaves, or the cool and ventilated place where the sunlight can be seen slightly indoors. At the same time, when the temperature is over 25 ℃, spray water on the leaf surface 1-2 times a day, 3-4 times when the temperature is over 30 ℃, and spray water on the ground around the flowerpot 2-3 times. To reduce temperature and increase air humidity.
Second, we should control fertilizer and water. In the high temperature season from July to August, we should stop fertilizing and control watering. The basin soil should be slightly dry.
Third, we should prevent the rain, which is easy to cause rotten roots and leaves.
Fourth, it is necessary to cultivate new seedlings. The old and perennial plants hanging upside down are sensitive to high temperature, while the seedlings have strong resistance to heat, and they will not shed leaves in summer. Therefore, it is a more positive measure to cultivate new seedlings by cutting every year for their safe summer.
Because the inverted hanging golden bell is in the axils of the new tip leaves with flower buds, so, to make it bloom more, we need to make it more branched, appropriate period of heart picking is an effective measure to make it more branched. Generally, when the seedlings grow to about 10 cm high, the first time of coring is carried out to promote their branching. After about 1 month, when the new branches grow 6-8 leaves, the second time of coring is carried out, and the redundant buds are removed. Each plant can retain 5-7 branches. After autumn cool, you can cut too long branches short, too dense branches sparse, so that it can promote healthy new branches. After each pruning, the watering should be reduced. After the new buds grow out, the watering amount should be increased gradually to restore the normal management.
Generally, after 25 days or so, the new shoots can bloom again. People can use this habit to adjust the flowering period and make them bloom continuously.
