Archontophoenix alexandrae VS Archontophoenix cunninghamiana, What's The Difference And How Do You Tell It?By PalmTreeDude
Hello, I looked up information about Archontophoenix cunninghamiana recently and I saw a lot of sites calling it the King Palm, yet, I thought Archontophoenix alexandrae was the King Palm? How do I tell these two palms apart and what's different about them? I am wanting to some day get a Archontophoenix cunninghamiana, but I'm afraid I'll get something else or a hybrid.
The first picture shows the newest spear on one of two pups on my needle palm suddenly is no longer green. I pulled on it and it slip up about an inch or two. The second picture shows the some of the leaves of the main plant and the other pup are still green. What should I do. I planted this in April (main plant and two pups all in the same 15 ish gallon pot) and all three plants produced new spears during the summer. Two weeks ago I I put down a little fertilizer that I had used twice before in the growing season (mid autumn fertilizer for needles in this zone is supposed to be helpful) added a couple of inches of black hardwood mulch around the plant being careful not to cover the crown. (Though I can't keep the leaves off it. ) There is a tip of a new spear and is also this pale blue color. I live near Olney, MD z7a., We have had two light frosts (not enough to kill my musha basjoo nor any of my alocasia or colcasia. So now what should I do? Do I pull this spear all the way out and also pull the tip of the newest spear? I have a liquid copper fungicide with copper Octanoate .08%. Do I spray the crown with that? Or is there a better fungicide to use? Advice is greatly appreciated! Thanks
Hi all this is my first post and I am in the Kill Devil Hills Area of OBX, NC. I have a few Sabal palms on my property and I recently planted 2 new 18 ft's last summer that rooted really well however I did not wrap them given the previous mild summer. So, of course, we had a terrible winter and all of my Sabals got some cold damage. Of the 2 I planted last year one is doing pretty good and has some really good growth and tight spears shooting through. The other has developed a soft trunk to about an inch in certain spots but is growing a nice spear but just incredibly slowly. I did dig around the palm and noticed that that around 18 inches it had solid roots that were alive and had grown significantly since I planted it. I cut off a lot of the brown fronds so it doesnt have a ton of nutrients getting to it. I included 2 pictures from June 11 and July 19. Any suggestions for further treatment beyond Copper Fungicide (I did treate it already)? Also, can these palms bounce back? Many thanks as this is my first post and I'm a recent memeber.
Today I notice a strange outgrowth from his Archontophoenix alexandrae. Is he going to blossom? Growing in a container of 12 litres, the age of 5 years. How often this type blooms in containers?
B. Odorata in the ground for two years. About 5.5ft tall.
The plant saw lows this winter of 12ºF and 14-15ºF twice. A few days ago I noticed some of the newest growth had died but it didn't alarm me at the time because the same had happened to the S. Mexicana.
When I took a closer look today, I noticed the new growth was dead all the way down to the base, in stark contrast to the Sabal. I gave a tug and the two newest fronds came out:
Leaving this bottomless pit:
Is there anything I can attempt like Hydrogen Peroxide or the partial beheading surgery? Does this look like damage induced by cold temperatures or cold rain? It saw no ice or snow this winter as I wrapped it for those events but it did see cold rain.
This comes as a total shock as the plant otherwise took minimal damage
