Q: I have 19 mature, healthy Mexican fan palms pruned every year after flowering. This year they were pruned on June 13, but after three weeks one suddenly died and another died two weeks later. I used the same pruning crew for five years with no problems. I removed about 250 square feet of turf from in front of the trees last year with no other significant changes to their irrigation or fertilization regimen.
Q: I have one pomegranate tree in bad shape. The leaves are turning yellow and then brown; yet underneath the veins are pink. This is one tree out of my 50 that looks like this. The other trees look great with a lot of new growth. Any ideas what could be happening with this one tree?
Q: You mentioned controlling borers with chemicals, but can borers in trees be controlled without using chemicals?

In addition, minimum nighttime temperatures stayed elevated well into the 90s for more days than I remember in the past.
