Well the monsoon storms are here and Trees are already falling over. Two storms into this season I have seen dozens and expect that over 100 trees have been blown over in the last couple of days. This poses the question, What can we do to help our trees from falling over in the Monsoon Storms?
The answers has many parts. First lets Identify the trees at High risk. Palo Verde and Mesquite. These two are the two most likely to fall but a close 3rd is the Eucalyptus, pines etc.
Why do they fall? Usually from poor planting and watering over the years. Landscapers and DIY planters often do not dig deep enough because our soil is so hard, this causes the tree to shoot higher surface roots than normal. Couple this with the use of drip irrigation on trees (a no no) and lack of deep watering and you have a tree ready to fall.
Prevention is in the form of deep soak watering and thinning. Cap off your drip irrigation, it only promotes surface growth, and water your trees according to kind bey leaving a trickle hose on them all night saturating the soil. Then, have your tree looked at by a professional tree service and get the needed work done. trimming can remove 1/3 of the branch weight allowing the tree to allow the wind to blow through without fractures.
With all that being said, Tucson has strong storms, our trees are in hard soil, our trees are heavy and mostly semi branch standard causing a likely hood of falling. Do all you can to so you do not have to call a tree service at 6pm to clear the tree off your house.
Hope this helps!
