Care of sago palm

Anonymous added on November 7, 2014 | Answered

We have 3 Sago palms in different areas of our yard and all of them have this white stuff growing on the leaves. I have put magnesium (pellet form) on them but it doesn't seem to be helping. What else can I do to protect them? They have grown new leaves but after a while they get the white junk on them too. Hope you can help!

Sounds like your plant may be affected by scale bugs. Scales normally infest the lower side of fronds before moving upward. Prune off all the infested fronds and dispose of them. Treat with horticultural oil or neem oil, available at most garden stores. Apply the oil to the fronds and insects, making sure to get the undersides of the fronds as well. You may need to reapply weekly for up to five weeks. Here is additional information that you may find helpful: https://www.gardeningknowhow.com/plant-problems/pests/insects/control-plant-scale.htm
