It is winter here in Arizona, and I had
some new queen palm trees planted about 5
months ago. My question is: How much
watering should I do (please give for year
round) and for how long & is there a way
to stop the yellowing in the branches. They
begin to yellow & then brown more & more.

part. With a newly installed tree, you should probably water once a week, and make sure the water penetrates 2-3 feet deep out to where the root zone is expanding. Use a pointed stick or piece of metal to push in the soil. It will move easily through moist soil and stop at dry soil. After five months and coming up to cool weather, you should be able to water your palms once every two-three weeks. At least once a month, water deeply enough to "leach" or push salts well below the root zone. Frequent, light "sprinklings" or short time spans with drip irrigation, allow salts to accumulate in the top layers of soil, where the roots are, which is bad news.

Similar symptoms occur when too much fertilizer has been applied. It's generally not advisable to fertilize landscape plants in our summer heat. Plant roots often "burn." I hope this information helps! part. With a newly installed tree, you should probably water once a week, and make sure the water penetrates 2-3 feet deep out to where the root zone is expanding.
