Water
Watering: To make sure that indoor grown Rhododendron simsii are permanently moist at the roots (they are almost always potted in pure peat moss) water them plentifully, giving enough at each watering to keep the potting mixture thoroughly moist. They dislike lime, so use soft, lime-free water.
Sunlight
Potted Rhododendron simsii in bud or bloom should be placed in bright light but out of the direct sunlight.
Fertilizer
Apply a lime-free liquid fertiliser once every two weeks from late spring to early autumn.

Soil
When we grow and care for Rhododendron simsii Planch, choose acidic soils with good drainage and good air permeability. Do not choose more viscous or alkaline soils. Some varieties of Rhododendron simsii Planch. are only suitable for mountain soils.
Pruning
To shape a rhododendron, follow the branch from the end down to the last whorl of leaves you want to keep. Make the cut about 1/4 inch above the topmost leaf in this cluster. Repeat as needed. Shaping is most easily done in late winter, while the plant is dormant.
Temperature
Temperature: Keep these plants in as cool position as possible, preferably 7-16°C (45-61°F). If the Rhododendron simsii are brought into warm rooms – above 20°C (68°F) – the roots will dry quickly, flower will flop and leaves will fall.
