1, preparation basin soil: cordate telosma likes loose, well-drained and organic-rich acidic soil. The pot soil is generally made of 3 parts of peat soil or humus soil, 2 parts of thick river mud and a small amount of farmyard manure. When potted, the bottom is filled with granular broken bricks about 1/5 deep to facilitate drainage of the pot, and the upper part is cultivated with the prepared pot soil.
2. Suitable environment: Potted cordate telosma requires a well-ventilated environment. It should be placed in the courtyard or on the balcony for maintenance from the beginning of May to the end of September. Although it likes sunshine, it should avoid exposure to the hot sun at noon in summer.
3. Fertilization: During its growth, liquid fertilizer should be applied every 10 day to 15 day, and thin liquid fertilizer should be applied every half month from late April to ensure continuous flowering from mid-May. If high-efficiency humic acid liquid fertilizer such as Chunquan 883 or Huimanfeng can be applied, the effect will be better.
4. Water transfer: Its summer is the peak season for growth. Except for applying sufficient fertilizer, the basin soil must be kept moist frequently, and watered twice a day if necessary. If it is a seedling, water should be sprayed on the leaves 1 time to 2 times a day.
5. Suitable temperature: it should be moved into the shed in the middle and late days of 10 every year, and the temperature in the shed should be kept at 8℃ to 12℃. If the temperature is lower than 5℃, the leaves will turn yellow and fall off until they die.
6. Pot changing: Pots should be changed before leaving the room in early April in spring. When changing pots, some old soil and roots should be removed, replaced with new culture soil, and re-cut to promote new branches. Keep the soil moist after changing pots, but there should be no water in the pots. If the young leaves droop slightly after changing pots, water them in time.
7. Adjust the plant shape: in the cultivation management, it is necessary to set up a shed, and the plants should be topped in time after they are put on the shed to promote multi-branching. After bloom, the residual pedicels should be cut off in time, and fertilizer should be added. After flowering, the dead branches and branches should be cut off and the overgrown branches should be truncated.
