Humidity range is from dry to wet for Sagos.
Light: Sago Palms grow in full sun, but adapt to outdoor shade or an indoor area which receives bright light or a few hours of morning or afternoon sun.
The Sago Palm growth rate is extremely slow. For example, in South Texas the fastest rate observed in commercial production (which has excellent growing conditions of hot summers and mild winters) under 30% shade is three new sets of leaves and an increase of 1" (3 cm) of height and trunk diameter per year. When grown as potted indoor specimens, Cycads may add only one set of new leaves every year or two and remain somewhat the same size (one reason they are excellent for bonsai).
