Can't find anything here about palm trees in Oklahoma so I will start a thread just FYI. Zone 6b-7a. On April of 86 I found this small palm at nearby garden center. I planted it on the front side of my condo facing east,totally blocked from the west .......attached units,other,condos,trees houses,etc to the north....and condos to the South. It was a Chinese Windmill Palm. Full sun most of the year from sunrise to about 1pm then shade from my unit. And I think it is well protected from heavy wind but not sure how well until it grows above the top of fence. The soil is good because of musa basjoo that grew there. It is planted about 4ft from wall. The first winter I just mulched it heavy and put a dense cardboard box on top of it when there was a freeze warning or ice. I kept it covered as long as 4 days because it was buried in snow. For the next winter(07) I mulched it again but this time I covered it with something called a Planket. http://www.theplanket.com/ It made it fine through the big ice storm. I did over sleep one morning and it was covered with ice so I covered it and the ice slowly melted with no damage. This time the leaves grew out all winter but slowly. I would say one foot length of the leaf. The rest of the leaf grew out quickly once the weather warmed up but minor damage. Oh.....I forgot to mentioned that 2 or three months before winter I give it a good dose of potassium. The trunk is about 24-30 inches now and has every leaf since planted. It looks so good that I just ordered a 6ft windmill palm to plant next to the other. Right now I am getting my walkway repaired and resurfaced and next week I will plant it when it arrives. I will post some pictures later. Also the type of fertilizer used.
