FAQs: Palms & CycadsCycad

1.  King Sago
1.  I have a King Sago that is showing a yellow flecking on the lower leaves and then there are some black spots developing around the edges of the leaflets.  What is this and how do I correct it?
Evaluate the plant!  Are there any insects (usually scale on the underside)?  If not, is it a disease?  Normally, a disease would affect all parts of the foliage not just the older fronds.  It could be a nutritional deficiency probably lack of potassium.  This can affect palms and cycads both.  Purchasing a complete palm special fertilizer that contains a slow release of nitrogen and potassium, plus extra magnesium and trace elements is recommended when buying a blended palm fertilizer.
