The invention discloses a method for controlling the flowering period of potted rhododendrons. In November of each year, potted rhododendron plants with full flower buds are selected and refrigerated at 4-6°C for 5-10 weeks to break the dormancy of their flower buds; after the dormancy is broken, the rhododendron plants need to be placed in 10 days of environmental transition at 18-20°C during the day and 8-12°C at night to promote the recovery of the root system from the dormant state to absorb water as soon as possible; Described flower forcing treatment is 10~12 hours of light every day, light intensity 5000~8000lx, 12~14 hours of darkness every day, temperature 22~25 ℃ during light period, temperature 10~14 ℃ during dark period, relative humidity is 50%~70%. The method of the invention can make the potted Rhododendron bloom in January to February (meeting the flower appreciation during New Year's Day and Spring Festival), and the proportion of flowers and leaves is appropriate, and has high ornamental value and commodity value.
