limbs on your pine trees dying
Watering nonnative trees in Mesa AZ
The massive mile high dust storm we had in 2013, has spread mites and other insects throughout the valley like I've never seen. This increase in insects and the record breaking heat of 2011 has dangerously stressed many tree species, particularly the pine trees.
Here is what you need to do if the limbs on your pines start dying:
1 Resist trimming - removing dead branches might make things look better but unless the branch has been dead for a few years it will probably cause sap loss where cut. Instead wait a year of so until the tree is insect free.
2 Increase watering immediately. Here in the desert it wouldn't hurt to exceed the amount of water a pine would get in its natural environment. Take a look at the annual rainfall in Washington State. Also notice how well large pines do in lawns that are green all year long. Pines need a lot of water! For more information on this subject please see Watering Non Native Trees on this website.
3 Starting immediately - treat your pines yearly with Bayer Advanced Tree and Shrub. Treat your tree annually as the deep borers are hard to kill. You can get Bayer Advanced Tree and Shrub at home depot.
4 have us treat your pines with medicines that will accelerate the healing process from the damage done from the micro pathogens carried by insects
