It still could be too much water. I would pull back the rocks add the iron and take the tree off the drip for a while. If it needs water use the hose. Dig down a few inches or use a small dia. stick or rebar to see how far down the soil is soft and wet. If needed turn the water on so it just barely comes out (dribble) for about 3hrs maybe 4. Don't know how many times per week you will figure it out. When it gets real hot and the leaves are no longer yellow maybe put it back on the drip. I would also consider mulching around it . Everthing in gardening is trial and error. And boy have I had few of those.

Most palm seeds form in spring and summer, but aren't mature until late fall or early winter. Windmill seeds look like big clusters of blueberries and stay on the tight through the winter. Sabal seeds are small blackish berries and also are ripe as winter approaches. They are often stripped bare by birds and animals, or blow off in the wind. So it's best to collect them a bit earlier. Needle palms don't seed as well as other palms. It may be part of the reason their range is more limited even though they are the most cold hardy palm. I've never seen the seeds, but the fruit reportedly smells like rancid butter. Whatever that smells like.

Hey Dischnell....I remember you. Long time no post:) I couldnt remember who from the group of us posters this summer had written that post. We got the same freeze....all my new plants look sad. The arecas on the side of the pool took a beating, but they are not dead....I am curious to see how the brown limbs come off. The tops are so brown....they will be half their size when they lose those fronds. I was told not to touch them and its killing me to leave half the plant brown. All my pink ixoras have no leaves....they were so beautiful. I have a Christmas palm in a pot by the pool. I wheeled it real close to the house under the lanai for 4 days and it looks fine. The heat from the house saved it! Several neighbors have extensive damage. The yard behind and next to me make my yard look fabulous compared to theirs. They had damage to everything including robellinis. One neighbor said he suffered so much damage because his sprinklers went off while it was freezing. Its amazing how some yards had no damage and others look awful. I actually believe those who constantly water, look better because their plants were so hydrated. This is just speculation to explain the severe differences....otherwise the wind blew harder around some houses. People like me who conserve water and stick to the winter watering schedule got hit worse. I keep hoping it will all recover quickly, it stinks that it might take 6 months for it to look good again. We got down to around 32. I had a thermometer set back about 8 feet from the house. I kept waking up all night to see what it read. It wasnt close enough to see from the slider (so I had to keep going out in the cold) but might have been too close to the house to not give an accurate reading. Those thermometers only got as low as 36, but my husband said his car said 33 at 5:30 am. Your chinese fans should be fine, they can go below freezing. My chinese fans, robellinis, foxtail, and queens look fine. You are right, the chinese fans are slow growers. How big did you buy them? Dont forget to regularly fertilized them as I am sure that will help them stay healthy and might help them grow a little faster.

After a week of 3+inches rain and cool weather; An oldie; 'Northern Halo' They just keep growing! Sprayed twice for slugs, but still killing 50+ big ones a night Francee, Gold Standard, Moonlight and Striptease (front to back) with Candy Dish in the left background Good spot to sit! Candlewood (by my right elbow) just keeping sprouting higher. One of my mother's montana seedlings, so it will grow large. Still one of my favorite plantings.
