I have a large date tree in my front garden which looks like the inside of it is dying. Some of the branches are also falling out. Can I do anything to save it?

My pygmy date palm is 4 years old, about 6 ft tall. It has four trunks. One of the trunks is turning brown. The others are fine. I don't see any bugs or fungus. I live in AZ, 112 degrees today. It gets plenty of water. What can I do or look for?
Apply a fungicide to see if this helps. Otherwise, you may need to prune off the browned trunk.
Can you remove half the stems on a 4 stemmed pygmy date palm without killing the entire plant?
I have a pigmy date palm that's 35 years old and 20ft tall...so pigmy is not accurate. I have never removed half of the branches, only the dead ones and have not had any problems.

My date trees are just starting to bloom and I think this is the wrong time of year for that, or is it? Do I try to pollinate them and see what happens or what do I do?
Although there are many kinds of date palms, I think most of them flower in the spring. A couple of things that may cause trees to flower at the wrong time - a young tree; like kids everywhere, sometimes just doesn't have its act together, and is not clear on when and how to do things; also, stress caused by upsets of things like water, weather, and soil chemistry can throw synchronization off. Here are a couple of articles that tell you more about date palms: https://www.gardeningknowhow.com/edible/fruits/date/date-palm-tree-care.htm

I have 2 pair of pygmy date palms and they are at least 12 years old. They are located inside a swimming pool screen room/enclosure and are starting to reach the top of the screen ceiling. I understand they only get about 10 feet in height, so what happens when they stop growing? Will they die?
You ask a couple of good questions, to which I don't have personal experience answers, nor could I find much information. I did find a couple of anecdotes concerning roebellini over 30 years old. I also found that they can, at times, grow to be 15'. I feel that your concern is that they might get too large for your space, and I do have a suggestion. Tall and mature PDP's cost several hundred dollars - with a few phone calls or messages you should be able to locate a landscaper who would be glad to come dig them up from your space, plant some new smaller ones or different plants if you choose, and pay you into the bargain. In the meantime, this article might add something to your knowledge. https://www.gardeningknowhow.com/houseplants/pygmy-palm/grow-pygmy-palm-trees.htm
I have a few date palms (seeds from Pella). They are flowering and I want to know as soon as there is fruit how to protect them from birds. I see they put bags around them...what type is it?
