Top Ten Tree Problems



  1. Trees and Shrubs Buried too Deep: When planting new trees and shrubs the hole should be no deeper than the depth of the container that is was grown in or in the case of palms no deeper than the root ball as it comes off of the truck. The hole can be wider and I always recommend a layer of mulch, but no deeper than 2 inches and do not let it touch the trunk of the tree.

  2. Over watering and Under watering: Usually what I see is over watering I believe it is the first reaction that most people think of when their plants look like they are having a problem such as leaf discoloration, or leaf drop. Make sure that you dig into the soil with your hand, soil probe, or even a shovel to make shore that the soil smells OK and is not a gray or black color that is associated with root rot.

  3. Borers: Borers are attracted to unhealthy trees. We usually find borers in Fruit trees such as purple leaf plum and most other fruit trees when they are between 8 and 10 yrs old. We can treat these trees with insecticide. But the best defense is to keep the trees healthy and unstressed.

  4. Aphids: Aphids are a small pearl like or Volkswagen shaped insect. An infestation can cause yellow discoloration and defoliation.

  5. Spider mites: Spider mites feeding can cause fine flecking or strippling of the foliage,  defoliation of plants, failure to fruit or fruit drop.  Female spider mites over winter in the cracks of the bark and in leaf litter under trees and shrubs. Species that are commonly effected are Italian cypress, Photinia, and Pyrocantha.

  6. Oyster Shell Scale insects: These insects target primarily ash, willow, poplar, boxwood, elm, sycamore, and blueberry trees.

  7. Fusarium Disease: Sertain species of fusarium can be harmful to trees under stress such Pheonix canariensis (Canary Island Date Palm) Ligustrum species(Texas Privet).

  8. Mealybugs: Mealybugs are another sucking insect that can cause discoloration of the leaves, and twig die back.

  9. White Grubs: White grubs are one phase in the life cycle of various beetles. They are usually a problem in spring and fall when they move up toward the soil suface to feed on the roots of trees, shrubs and turf.

  10. Leaf Scorch: The high and low temperatures in the valley are exteme for most plants to grow virorously.
