Scale on Cycads is something I may take too seriously. Asian scale is currently decimating large native populations of Cycas.
Most of mine are grown from seed and I do go to great lengths to inspect plants that come from states where this may be present.

The common pest such as spider mites, brown scale, mealybugs etc generally don't bother with Cycads too much.

"The aulacaspsis scale is fatal for most species of the genus Cycas, yet members of the genera Ceratozamia, Dioon, Encephalartos, Macrozamia, Microcycas, and Zamia are effectively unharmed by this scale pest. While none of these plants are common in the nursery trade, the Dioon (pronounced dye-oon) species may be the best replacements for the king and queen sago. They are easy to grow in south Florida, are among the easiest of the large cycads to find in wholesale nurseries, and are similar in size to the king and queen sago. While they do not have widely used common names in English, their scientific names are not terribly long."

Yea, I definatly KNOW that YOUR tree did not have it when you gave it to me. About a month or so later, my youngest's babysetter was given two Citrus trees. I saw them in her garage and she offered them to me. I was hesitant as I could see they had HORRIBLE scale. But me being a Citrus lover, I took them.
But yea, I would love to try another one, but this time planted on my South facing wall that gets actually good Sun from morning until night.

First Sago in the GH - Still like watching these unfurl 8)

Steve,I went ahead and planted mine next to my T.fortuneri,so far the cold hasn't hurt it any,but it's still too soon to tell,was 23* this morning when I got up! They say 15* tonite!!!!
I also love to see them unfurl as well!
Yours is looking great!

Yikes 15F

Hope all your plants come through this.

Good Luck.

Thanks,will be keeping my fingers crossed tonite!!!

I went ahead and pulled up the pots of my Yucca Trechy & the one Sego I had in front.
So far, everything in the greenhouse is staying good. I have a lil heater in there and it seems to be keeping up.

Nice shot! What do you use to heat your greenhouse, KNN? Your plants seem to love it, and in zone 5 it must be a challenge.

Thanks Lori! been using two 1500w electric heaters, did manage to keep the containers above freezing on the coldest nights.
( Many nights with icecicles hanging inside from the roof 😆

Little further along now.....

C.taitungensis seedling....Just need 2-3 weeks of warm weather to get everthing else going!

And a couple Dioon leaves reaching for sunlight.........( they will get a better spot this year 8)

Always a pleasant sight to see!

Doing my best to get some decent looking leaves this season, had a couple new arrivals......should fill in nicely in a month or two 8)

Steve

Looking like cycad city!!!!
