Question
I have 2 sago's about 1 1/2 years old and both or planted in the ground. We live in central Texas.  Our plants have developed yellow spots on some of the leaf stems.  One plant more than the other.  I also have a 5 year old in a large pot that has some of the same yellow spots a just a few leaf stems.  1 Of the smaller in ground plants have put out about 17 new leaves and the older plant in the pot has just sent out 27 new leaf stems.  Please help me ASAP as to what may be going on with the plant.

Answer
Hi margaret, this is a question I answered awhile back here is my reply:
Reports of Asian Scale sightings are becoming common in almost central and south Florida towns. Areas just seeing the scale for the first time, just 6 months ago are now becoming so infested that its hard to find a Sago palm that is "not" covered with scale.   Extremely persistent and difficult to get rid of. Many report that if you treat the sago with pesticides consistently enough, you can rid the plant of the scale, while others are insisting the bug has the ability to armor itself away from pesticides and keep coming back because you cant completely kill them off a plant once infested.  Some will remain in armor or dormant like state and try again for life after treatment is relaxed.    Watch out for the problems above as this palm is one you have to watch allot. You can cover the roots but do not go above that.

Since then I have discovered a product called Atomic Grow that will clean the plant and start the healing process so it will be able to defend against bug attacks.  kathy
