Azalea greenhouse cultivation
Rhododendron simsii Planch.
The cultivation of Rhododendron simsii in indoor environments requires strict control of dormancy period temperatures, substrate acidity, and specific lighting conditions.
In the reference 8 varieties crop Indica azalea, where this is mentioned in the description.
For the commercial production of Rhododendron simsii in a greenhouse, it is critical to observe a dormancy period at temperatures of 5–8 °C for two months, which is necessary for flower bud initiation. Plants require intense diffused light, as direct sunlight causes leaf scorch and flower wilting. High air humidity must be maintained while avoiding water contact with the flowers to prevent rot.
Technological requirements include maintaining a strict substrate pH range of 4.0–4.5; deviations from this range induce chlorosis. Due to their shallow root system, azaleas are grown in low-profile containers to prevent waterlogging. Unlike many potted crops, the propagation of slow-growing azalea cultivars involves grafting onto vigorous rootstocks.
