Location
bright and sunny with lots of air. At midday the plant should be protected from direct sunlight. Hoya can not bear to fresh air. winter temperature – 12-15 degrees. At higher temperatures, the plant does not die, but the lack of a rest period would adversely affect its flowering.
Lighting
Glare
Watering
during the regular growth. We should not allow drying earthen clod.
Air humidity
Moderate
Humidity: For more information
During the distillation should spray the plant.
Care
To keep the plant in an upright position requires a solid support. The young plants are transplanted each year, as they rapidly evolve into a more bulky utensils, old (adult) plants transplanted once every 3 years. To enhance the growth of vegetative shoots fertilizers are applied 2 times per month from April to September. As fertilizer use complete fertilizer at the rate of 40 g in 10 liters of water once a month, and again – slurry. High light intensity (light windows in the rooms) activates the formation of flower buds. Flowering lasts until autumn. Flower stalks after flowering should not be deleted, because next year they appear buds – flowers (a profusion of flowering plant rooms stimulated by immersion for 30 minutes in warm (35 °) water and clod – 2 pm, in the spring and fall) .
Reproduction
Plants propagated by cuttings in spring and autumn (feasible for the entire year of vegetation). Cuttings of cut one, two pairs of leaves, but can be used longer. Substrate for the propagation of peat up – 2 hours, sand – 1 h. The appearance of roots in the petiole is not on the nodes and between nodes, so the cut does not produce the cuttings under a node, and below the site. The optimum temperature for the establishment of at least 20 °. Cuttings root easily waxy ivy and under ambient conditions (air and can be propagated by layering, and leaves with axillary buds). Rooted (20-25th day) cuttings are planted in 9-cm pots. The composition of the earth is the following: sod – 1 hr, leaf – 2 hours, humous – 1 / 2 hours and sand – 1 hr, superphosphate, potassium, ammonium sulfate are made of 2 kg per 1 cubic meter. the mixture. Plants need abundant watering, especially during the period of intensive growth. Location recommended a bright, sunny as possible. In winter watering limits, but the earthy components do not lead to complete drying. Temperature for all the wax ivy should not be below 16 ° (the exception is H. carnosa, it contains at 13 °). In the summer, but abundant watering, spraying and need room ventilation, the optimal temperature for their growth and development of 22-25 °. The plants flower profusely.
Transplantation
As required in the spring.
