My palm tree has developed some white growth around the stem and along the branches from the center. Is this normal? Many thanks.

This is Asian Scale, very problematic but relatively easy to control. If you have a bad infestation, Malithon and Horticultural Oil at maximum rates. You will have to saturate the crown and trunk, pay particular attention to the bottom of the froms, with left over spray drench the soil around the trunk, any problem you see above ground is 2 times worse below ground. Once under control Horticultural Oil will control the scale using the same procedure every 6-8 weeks.You will need at least a gallon per Sago.

Catharine Mannion at the University of Florida has done a significant amount of research with the Cycad Scale. It is devastating the industry down there and unfortunately there are not a lot of options. Many growers simply have stopped producing cycad. Catharine has done research with both biological control agents and chemicals. "I attended an Entomology meeting where she presented some of her data from this research. From what she presented, four applications of horticultural oil two weeks apart and with THOROUGH coverage did as well as the currently recommended chemical products in Florida

Sago palms, which are not really palms, but cycads, as Walter mentions, have been nearly wiped out in some parts of the state because of this problem. It looks like you have caught the problem early on and with vigilance you should be able to save your sago. Good luck!
