Frequently Asked Questions

Autumn blaze maples need more clay-like, acidic, and loamy soil. The Denver metro area has a mix of acidic and sandy alkaline soils, and it is practically impossible to amend that soil. If your Autumn blaze maple leaves turn yellow, you can find a professional to drench the soil with iron, nitrogen, manganese, and magnesium. You can often prevent this by fertilizing your tree twice a year, which may help your tree recover.

The elm leaf beetle, Japanese beetle, elm leaf miner, and European elm flea weevil all take their toll on the well-being of your elm tree and can often cause defoliation. If you have your tree treated yearly, the tree will improve. Squirrels can also be a problem in Siberian olive, maple, and other sweet bark trees, leading to mass limb dieback.

Silver maples are softwood trees. If dead and broken branches are not pruned out of the silver maple promptly, the Long Tailed Giant Ichneumon wasp will eat into the areas where the tree is exposed. These areas include broken branches and rotted holes in the tree trunk. The insect lays its eggs in the wood, which hatch into larvae and then attract woodpeckers to dig into your tree. These holes created by the woodpecker can increase in size and develop cavities due to water erosion and squirrel damage.

Pine trees drop their needles on the inside of their canopy every two years. These needles can pile up on the limbs, giving the appearance of dead limbs. This needle drop is expected. However, if you see dead needles on the tips of branches, we would need to come out to evaluate the tree for trimming.

Yes, you should have your ash tree treated by a professional to prevent the effects of the emerald ash bore. This insect can be devastating to your tree's health, even leading to the tree's death if not treated promptly.
