Growth Habits of Black Diamond Rubber Tree

Black diamond rubber tree likes high temperature, humid, sunny environment, suitable growth temperature of 20~25℃, avoid direct sunlight, but also can withstand shade but not cold, safe winter temperature of 5℃. Resistance to air drying. Avoid clayey soil, barren and drought resistance, like loose, fertile and good drainage of slightly acidic soil.

Black diamond rubber tree propagation method

1, cuttage method: cuttage time in late spring and early summer, can be combined with pruning, cuttings more than 1 year old semi-lignified central branches, should be timely with plaster or plant ash will be sealed wounds. The length of the cuttings is based on the standard of retaining 3 buds. Cut off one leaf below, close the upper two leaves, and tie them with thin plastic ropes. Then cuttage in plain sand or frog stone for the substrate of the cutting bed. After insertion, keep the cutting bed with high humidity, but do not accumulate water, the appropriate temperature is 18~25℃, often sprinkle water on the ground to improve the air humidity, and do a good job of shading and ventilation, about 2~3 weeks can take root.

2, layering method: select 2-year-old branches of appropriate size, well-developed, well-organized, in the predetermined part of the soil for a width of about 1 cm of light ring peeling, and coated with 30~50ppm of naphthylacetic acid solution, and then wet soil or moss mixture or vermiculite to absorb enough water, the ring cut parts wrapped up, wrapped with plastic film outside, tied at the lower end, the upper end of the hole to facilitate ventilation and irrigation. Pay attention to maintenance, layering in June, rooting in July ~ August. After taking root, you can cut the potted plant.

Black diamond rubber tree cultivation method

1, reasonable fertilization: black diamond rubber tree fertilization should be based on nitrogen, with a small amount of phosphorus and potassium fertilizer. Can be retting a good system of soybean water, bean cake water diluted irrigation roots, the general concentration of 20% can be. Inorganic fertilizers, such as urea, can also be used, but they should be applied less frequently, not thick fertilizer, and avoid burning roots.

2, soil configuration: black diamond rubber tree potted with 1 part of rotten leaf soil, 1 part of garden soil and 1 part of river sand, and add a small amount of base fertilizer, mixed into culture soil. It grows very fast in a high temperature and humid environment, and can produce a leaf every 5 to 10 days. During this period, sufficient fertilizer and moisture must be ensured.

3, light management: black diamond rubber trees like strong sunlight, spring to autumn throughout the growth season should be placed in the sun cultivation, winter should also be placed in strong light. But it can also bear shade, in indoor low light cultivation, but also better.

4, temperature control: black diamond rubber tree growth suitable temperature is between 20~30℃, at 25~30℃ when the most vigorous growth. Below 10℃, it grows poorly, and below 0℃, it is vulnerable to freezing damage. Black diamond rubber tree in the indoor if subjected to cold wind, there will be yellow leaves, deciduous phenomenon.

5, timely watering: black diamond rubber trees like water, but not resistant to water damage, waterlogging phenomenon, roots do not get oxygen, there will be yellow leaves, deciduous phenomenon. Watering should follow the principle of "see dry see wet", do not water too frequently. Winter should be spent indoors, generally watering once a week, summer should be decided according to the weather and pot soil humidity!

6, reasonable pruning: in order to make the black diamond rubber tree grow evenly, to ensure good plant shape, in the seedlings grow to 50~80 cm height should be removed, in order to promote lateral germination. After the lateral branches grow out, 3~5 branches are selected, and then the lateral branches are short-cut once a year. After 2~3 years, larger plants with complete plant shape and round fullness can be obtained.

7. Pest control

① leaf spot disease: black diamond rubber tree if found leaf spot disease, can use chlorothalonil or carbendazim 800 times solution for foliar spray, once a week, 2~3 times in a row can be basically cured.

Anthrax: Anthrax is not easy to find in the early stage. At first, it is only a small brown spot on the leaves. If it is not treated in time, it will rapidly expand into pieces and lose its ornamental value. Therefore, once the disease is discovered, it should be immediately sprayed with 400 times of thiophanate-methyl solution once a week for 3 consecutive times, which can generally be cured.

Root rot disease: Root rot disease is generally caused by Rhizoctonia or Pythium infection in the soil or by its physiological diseases. Bacterial infection can be treated by 500 times solution irrigation of Dixong, Dijunling or quintozene. Physiological diseases are mostly caused by too heavy soil, too much watering, and the root system cannot breathe. Soil with good drainage can be replaced.
