If you posted in the "Tool Shed" section you would have found enthusiastic response! I'm one of those guys that loves to do it all myself. I have the chainsaws and even a chipper to turn it all into compost. For a chainsaw I think you are on the right track. Consider the Echo CS-370 with the 16" bar. You could get by with a 14" bar with this little cabbage palm but you will be glad to have the extra length on other projects that will come along. I also have a gas pole saw with extensions and a 12" bar. It isn't telescopic. I just add or remove a section as needed. Wonderful tool. I keep my neighbors properties and my own pruned and tend to do it at the onset of Hurricane season. I never charge them but I seem to get a lot of cold beer from them. For this tree, I would drop it whole to the ground since you mentioned that you have plenty of room. Buck it after you drop it. Be sure to keep your chain out of the sand as it will dull it instantly on contact. Palm wood is hard on chains to begin with. It is stringy stuff and actually has sand in it. It would be advisable to purchase an extra chain and a sharpening file so you can touch up the chain between tanks of fuel. One thing to add here is that there is more to buy then just the saws. You should be wearing chainsaw chaps, steel toe boots, and eye and ear protection. I have a forestry hat that takes care of the eye and ear protection and use it for lots of other chores like running the chipper and even weed wacking. The great thing about the forestry helmet is that the eye screen and ear muffs can be pivoted up between cuts. Have fun with the job and be safe.

You are supposed to leave the it if there is some green in it. I know, it looks ugly while recuperating, but new growth should be better off for it. Winter sun is hard on evergreen...especially in a WINDY site. I would think about sitting it on wheels eventually and rolling it into a move sheltered position over the Winter (less sun, less wind). Wrapping the foliage and trunk and the pot with some burlap would not hurt in the Winter either. Good luck.

Yes. Easy as pie. You can dig them in,or sort of lay them on top and surround with bark- they will cover that pretty fast. Some are fast to send out many pups and can cover ground quickly. Fireball is one of the best and its hybrids that add variety. A good and big and fast brom is Aechmea caudata..very hardy although its a generic green on its 3-4' height. Great bloom though.

That looks like freeze damage to me. Freeze damage doesn't usually show up immediately, sometimes it'll start showing up several days after. I checked the weather for Dallas and it looks like on the 5th, 6th, 7th and 8th of January, Dallas had low temperatures of 27F, 21F. 17F and 24F. On the 7th, the high was 27F, which means it was below freezing for at least 24 hours. I think 17 degrees is pretty close to the temperature limit for chamaerops. You posted this on the 13th, which seems like an appropriate time frame for freeze damage to show.
