Hi Rich, I think you may be over watering.  See below.  kathy

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).

Sago Palm Longevity: Cycas revoluta are extremely long lived and old specimens can grow in curious ways. Many Sago have multi-trunks and multiple branches.

Sago Palm Soil should be well drained and rich in humus, although these durable plants seem to grow in almost anything. In the landscape or garden, be sure to plant Sagos slightly above the soil line and not in a hole or depression which retains water or is "swampy". Sago Palm much prefer to be on the dry than the wet side.

Sago Palm Water and fertilizer needs are related to the amount of light available. Unlike most plants which can wilt when dry or turn yellow from lack of fertilizer, Cycads give little indication of when to water or feed. Generally, they should be treated as a cactus and watered when almost dry.

Watering: If grown in a container, take care to allow the soil to become almost dry, then water the Sago Palm thoroughly slowly adding water around the top of the soil.   If the Sago Palm is receiving morning or afternoon sun or temperatures are warm, the Sago plant may need to be watered at least weekly. Sagos grown in low light or cool temperatures may need water every few weeks or so.  If the cold hardy Sago Palm is planted in the landscape, water when dry, but do not keep continuously wet. Established Sagos can easily survive drought conditions.
