Telosma cordata (Burm. f.) Merr. is native to southern China. It grows in hillside bushes and is now cultivated in various southern provinces. It is cultivated in tropical and subtropical Asia, Europe and America.

Growth habit of Telosma cordata (Burm. f.) Merr.

Telosma cordata plant mainly grows in jungles, woodlands or shrubs in subtropical and warm temperate regions. telosma cordata (Burm. f.) Merr. likes a warm, humid, sunny, well-ventilated, dry climate, good drainage and a loose and fertile environment. Drought-tolerant, barren-tolerant, waterlogging-tolerant, cold-tolerant, it stops growing after deciduous in winter; after the warmth of spring, branches grow and leaves, each node has axillary buds or flower buds, and side branches and inflorescences continue to grow as they grow, generally from May to October It blooms successively, the smell is fragrant when blooming, and it is more fragrant at night. Winter results. It has strong adaptability to the environment, strong vitality, and developed root system. It starts to bloom every spring and has a long flowering period. telosma cordata (Burm. f.) Merr. has high requirements for temperature. The average annual temperature is controlled at about 20 degrees Celsius. Evening tuber is a kind of fertilizer-loving plant, so it needs to be fertilized several times during its growth. Telosma cordata (Burm. f.) Merr. is also very demanding on water. You need to water more in the hot summer and keep the soil moist in winter but remember to waterlogging. Especially to avoid frost, the Yangtze River basin can only be potted, pruning resistant.

Telosma cordata (Burm. f.) Merr.'s Propagation

The propagation of Telosma cordata (Burm. f.) Merr. mainly include cutting propagation, layering propagation, ramification propagation, and seedling breeding. The most commonly used method is cutting propagation. In addition to winter cutting propagation can be reproduced.

Choose inserts: The branches of Telosma cordata (Burm. f.) Merr. should be selected that are robust or have no pests and diseases. On the same plant, the middle and upper branches of the current year should be selected to face the sun. The branches are required to have short internodes, thick branches and leaves, and full bud tips. Branches and long branches that are about to bloom.

Choose the substrate: Use peat soil, leaf soil, and Gaza to prepare 3:3:4 respectively. The bed soil prepared in this way has the characteristics of increased bed temperature, water retention, aeration, fertility, and partial acidity. It is suitable for Telosma cordata (Burm. f.) Merr. .Branches take root and sprout.

Before cutting Telosma cordata (Burm. f.) Merr., treat the cuttings with ABT rooting powder and other agents to promote rooting. Cut the cuttings into a section of 8 cm to 12 cm with 2 to 3 buds. The cut in the lower part of the cutting should be 0.5 cm below the node. The cut should be smooth. Cut off the lower leaves, leaving only 2 to 3 at the top. For each blade, the insertion depth is generally about 3 cm.

Rooting conditions: The suitable rooting temperature for Telosma cordata (Burm. f.) Merr. is 20°C to 24°C. Generally, the soil temperature is 3°C to 5°C higher than the air temperature for rooting. The relative humidity of the air in the slotting bed is 80% to 90%, which is good for rooting and requires light at about 30%. The water content should be appropriate, the cuttings are slightly larger in the early stage and slightly dry in the later stage. The suitable period for local open-field cuttings is from early May to mid-June. At this time, the climate is better, which can better meet the temperature and humidity conditions required for rooting of cuttings.

Strengthen post-insertion management. After inserting, Telosma cordata (Burm. f.) Merr. should be watered thoroughly, covered with plastic film, and placed in a relatively shaded place, or scattered grass on the film to prevent direct sunlight, and increase the light at night to help the cuttings survive. Let the air out once or twice a day to supplement the required oxygen and prevent the occurrence of diseases. Always spray water to keep the slotting bed moderately moist, but not excessive spraying, otherwise the slotting bed will be too wet, which will often affect the healing and rooting of the cuttings. When the new roots of the cuttings grow to 2 cm to 3 cm, the pots can be transplanted in due course. After flowering, the Nanjing area should be moved indoors for maintenance in winter.

How to grow and care for Telosma Cordata

The soil

Telosma Cordata prefers loose, well-drained, organic-rich acidic soils. The pot soil is generally made of peat soil or leaf soil 3 parts of thick river mud 2 parts and a small amount of farmhouse fertilizer. When potting, the bottom of the pot is about 1/5 deep filled with granular broken brick blocks to facilitate the basin drainage, and the upper part is cultivated with good pot soil.[ 

Light

Potted Telosma Cordata requires well-ventilated environmental conditions and should be kept in the yard or on the balcony from the beginning of spring to the end of autumn. Although Telosma Cordata likes sufficient sunshine, it should be avoided in the noon of summer. 

Fertilization

In Telosma Cordata growth process, should every 10 days to 15 days of application of liquid fertilizer, in late spring every half a month of application of thin liquid fertilizer, from the middle of spring can ensure continuous flowering, such as the application of Chunquan 883 or Huimanfeng and other efficient humic acid liquid fertilizer, the effect is better.

The diversion

Its summer is Telosma Cordata growth season, in addition to apply sufficient fertilizer outside the basin soil must be kept often wet, when necessary, a day to water 1-times.If seedlings, should spray 1 to 2 times a day to the foliage. 

Temperature

Telosma Cordata should be moved into the shed in the middle and late autumn every year, and the temperature of the shed should be maintained at 8℃ to 12℃. If the temperature is lower than 5℃, the leaves will wither and fall off until death. 

Ropotting

Repot for Telosma Cordata should be carried out in early  spring before going out of the room. When repot, part of the old soil and old roots should be removed, and new culture soil should be replaced, and recut to promote the growth of new branches. After changing the pot to keep the soil moist, but there can be no water in the pot, after changing the pot if found slightly drooping young leaves, to water in time. 

Repair plant

In the cultivation management, scaffolding should be set up, and the plants should be topped in time after the shed to promote more branching. After the flowers bloom, the residual pedicels should be cut off in time, and fertilizer should be applied. After the flowers fade, the dry branches and over-dense branches should be cut off, and the short treatment of the barren length should be carried out. Twists of Telosma Cordata grow quickly -- about a meter in a year if left to grow naturally -- so they need to be pruned every year to produce more lateral shoots and flowers. Generally pruning is done in the fall, leaving each lateral branch 10-12 cm long. Dry branches and overdense branches should be cut off after the flower has faded.
