What are propagation methods of Pentas Lanceolata (Egyptian starcluster)? Pentas Lanceolata generally propagates through seed sowing, and cutting propagation. The operation process is not very complicated. The following is a complete seed sowing and cutting propagation methods of Pentas Lanceolata.
The seeds of Pentas Lanceolata (Egyptian starcluster) should be prepared first. In addition, a hole tray should be prepared as a seedling raising facility.
Generally, the soil for sowing is rich in humus, with good drainage and sterile soil, and the clay content in the soil is 10%-20%. Materials such as coconut fiber and perlite can be appropriately added into the soil.
First, seed Pentas Lanceolata (Egyptian starcluster) was seeded on the disc. Remember to plant one seed per hole. The hole size should be 1.5 -- 2 cm.
Generally, seeds of Pentas Lanceolata will germinate about 10 -- 14 days after sowing, with the germination temperature controlled at 23℃ -- 26℃, and the relative humidity in the air should be kept at 100%, until the leaves of Pentas Lanceolata grow out.
Pentas Lanceolata (Egyptian starcluster) seeds should be fully hydrated during germination. In addition, the dissolution of the outer layer of the quick powder Flower can be added to promote germination.
The seeds of Pentas Lanceolata (Egyptian starcluster) can be transplanted into pots 7 to 9 weeks after sowing. The diameter of the pots should be 10 to 15 cm. Sterile peat soil with a little fertilizer and good drainage should be selected as the cultivation substrate, with a PH value of 6.5-6.8.
Pentas Lanceolata (Egyptian starcluster) seeds are sown with a fully balanced fertilizer of one to one kilogram per cubic meter and a slow release fertilizer of one kilogram per cubic meter in the matrix to keep the soil fertile for sowing and, in short, to provide the seeds with sufficient nutrients.
Relative humidity should be reduced to 50% during the growth stage of cave-disc seedlings to prevent leaf diseases.
During germination, if the illumination is kept stable at 1000 lux, the new buds will grow more orderly and of higher quality, and the illumination after germination will be maintained at 10000-25000 lux. As the seedlings grow, the illumination must increase to 50,000 lux and the temperature must be controlled.
Let the seedlings receive sunlight as soon as possible after germination to avoid the phenomenon of vain growth and promote the rapid growth of the plants.
The propagation of Pentas Lanceolata (Egyptian starcluster) is mainly based on cutting propagation. Generally, it can be carried out all the year round, but spring and autumn are the best time for cutting propagation. Generally in the autumn, combined with pruning cuttings, the original plant can also do the renewal of the branches.
When cutting Pentas Lanceolata (Egyptian starcluster), suitable cuttings should be selected. It is better to have strong, intersegmental branches with terminal shoots.
When cutting cuttings, select branches with terminal buds and 3-5 internodes with a length of 5-10cm. After cutting, cut off the flowers and buds, and remove the lower leaves.
Make a hole in the bottom of a clear plastic cup, then put the blue stone on the bottom and add water. Put the prepared cuttings into the cup for aquatic root induction.
Be careful that the water level is not too high during root luring.
Rooting normally takes about 1 to 2 weeks. Once the roots have grown, transplant them into a small pot and place them in a well-lit area. After the roots have grown more complete, the planting is carried out.
