yellow spots on SAGO PALM LEAVES

Re: yellow spots on SAGO PALM LEAVES
A condition called frizzle top is probably the most common problem. This is a manganese deficiency causing the new leaves or upper leaves to turn yellow. This will start as spots and eventually the entire leaf is covered. There is a way to correct this. Spray the leaves with manganese sulfate. Once a month for three months mix one teaspoon of manganese sulfate per gallon of water. You can also apply one to five pounds (gauging with the size of the plant) of manganese to the soil in the springtime to correct or prevent the problem. Along with this recommendation, it is always wise to have a soil pH check and to check the moisture content of the soil. As always, too much water and less than desirable drainage will cause root damage. If that is the case, the sago will be unable to absorb the nutrients.
The most common insect problem sagos have are scale insects. The magnolia white scale being the most common. Recently there is a scale from Southeast Asia that is becoming very serious. To date nothing has been able to fight the condition. The affected cycads are coated with a white crust. Scales will suck all the juices out of the leaves and the cycad will die in a matter of weeks.
