The blue palo verde is a moderately tall shrub-like tree with distinctive blue-green branches and needles. The tree blooms yellow flowers in the spring, sheds its needles during dry periods, and experiences growths after rains. If you live in a desert-like climate, a blue palo verde tree might serve as a great, colorful addition to your yard or property.
Owning a tree of any type requires some maintenance, which can include monitoring the tree for signs of tree diseases and insect infestations and calling in a tree care service for help where needed. What are some of the tree diseases that commonly strike the blue palo verde tree?
Slime flux is a bacterial disease that causes a wet, foul-smelling ooze to flow down the bark from weak spots in the wood. The ooze damages and can kill the tree tissue it drips down onto. In a mostly healthy tree, the slime flux isn't a major threat to the life of the tree. If the tree has quite a bit of damage due to improper watering or storms, the disease can worsen. Severe slime flux can start to cause general dieback in the tree, which can cause an abundance of needle shedding and the flowers to fall off earlier in the year.
Minor to moderate slime flux infections can be treated by a tree trimming service carefully pruning off the affected branches. Severe slime flux might cause the death of the tree following a few years of decreasing health. A tree removal service will take care of the tree in the case of severe slime flux.
Ganoderma Root Rot
This fungal root rot infection takes hold first in the root and can cause significant damage underground before major symptoms become visible aboveground. And above ground symptoms are similar to general dieback with premature flower and needle loss and weakening branch growth. Severe root rot can cause knobby conks to form on the branch bark.
The best chances for the tree to survive the infection is a previous heartiness and regular pruning and maintenance by a tree care service. If the conks are already present on the bark, call in a tree removal service as the root rot has become too severe to treat. Dead roots can cause the tree to tip over during a windstorm.
Root borers are a type of beetle that can infest the blue palo verde tree. Female borers lay eggs in the soil near the tree's roots. When the larvae hatch, the larvae feed on the tree material in the roots. Heavy root borer infestations can cause significant root damage or make the tree more vulnerable to root diseases. The larvae can then grow to become adults, which are large, cockroach-like pests.
If you suspect a root borer infestation, call in a tree care service or pest control service to help deal with the problem. Adults can often be plucked out by hand but larvae or eggs might require chemical treatments.
