White Powder on Sago

I have a white powder on the center and some leaves of my sago. What is it, and if necessary, how do I remove it? It is mostly center towards the bottom of the stems.

While you can't really prevent it from growing, you can prune it back to keep its growth under control. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/trees/sago-palm/prune-sago-palm.htm

Transplant My Sago Palms

I want to transplant my sago palms due to the fact they poisoned my dog. I need to know how big the roots are on a 4′ wide plant?

ANSWERS

The general rule of thumb is that the roots will extend out 1-2' beyond the tips of the fronds. Sorry to hear about your dog. :(

How to Keep Sago Palm the Same Height

The Sago palm is planted under the front window of the house. I don’t want it to get any taller. It’s very healthy. How can I keep it at it’s current height?

ANSWERS

There is not much you can do to keep it forever from growing up. Due to the nature of their growth, if they are completely prevented from growing up, they will die.

You can, however, make sure not to accelerate its growth. I would limit fertilizers to the plant, for sure and do not over water.

Sago Palms in Winter

We have two sago palms that are mature (about 6 years old) that we transplanted outside this spring and they have done beautifully.

I am wondering what we need to do to them to prepare them for the winter. We live on the eastern coast in Virginia and many people around here seem to wrap their sagos in burlap, as we can have a few weeks of low teen temperatures. Is that necessary? What would be the best way to make sure they will live through the winter?

Wrapping them can help, but only if it is for short spurts of cold. This article will help for future reference: https://www.gardeningknowhow.com/plant-problems/environmental/frost-how-to-protect-your-plants.htm

Many people don't realize this, but sagos aren't actually palms at all but cycads. These plants are extremely hardy, surviving both heat and cold well. In fact, during summer the plant tolerates drought-like conditions while in winter it is cold hardy to 20 degrees F. Your neck of the woods doesn't usually experience harsh winters, as northern climates do. Unless it's grown in a pot (which should be brought indoors or wrapped) or located in excessively windy areas, there's little you need to do over winter. It should handle the cold just fine. In fact, the plant may only exhibit slight browning from the weather but this can easily be remedied through pruning.

Scale on Sago Palms

I have been treating my sagos for scale, with a oil base treatment. Is there anything new out?

ANSWERS

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, 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. You can also try neem oil. It is organic and harmless to humans and pets but still kills scale very well.
