mesquite twig girdler.

How do you treat mesquite trees?
The most effective way to control mesquite is to mechanically or chemically kill the buds at the base of the stem to prevent resprouting. This can be accomplished by root plowing, grubbing (digging up the roots of individual plants) or use of herbicides. Additional management options include the use of prescribed fire.

What is the lifespan of a mesquite tree?
200 years

Can mesquite trees get too much water?
Arizona researchers found that mesquites develop top growth during the rainy season and roots during dry times. Applying too much water produces lots of top growth, but the intermediary leaves can’t get light, so they drop. This is one reason why a lot of trees blow over during strong winds.
Why are the leaves on my mesquite tree turning yellow?
Although yellowing leaves often indicate a lack of water, it can also mean that roots are sitting in water and drowning. This root die-off will result in the tree’s inability to take up enough moisture. Check the soil to make sure it isn’t soggy, and don’t plant mesquite trees in areas where runoff collects.
How do you stop mesquite trees from dripping sap?
The sap is water soluble and a daily roof washing could eliminate damage. In some cases, you can stop a tree from dripping sap by pruning it. Using a pair of sharp gardening shears, cut off any small branches that are dripping sap. It’s recommended that you prune trees during the spring or fall.
