Spraying a tree to rid pests near Highlands Ranch, Colorado.

Hundreds of Colorado homeowners and businesses adorn their outdoor landscapes with trees and shrubs, and it’s not hard to see why. These woody plants don’t just add color and structure; they also create desirable focal points. Many favor them for their hard-wearing and seemingly self-sufficient nature, but that doesn’t mean that they don’t need maintenance.

A host of pests and diseases can quickly and easily take over an entire yard of trees and shrubs if they don't receive the proper care. At Tree Keepers, we provide a variety of plant health care services that will proactively keep your plants healthy and resistant to infections or infestations. These include:

  • Fertilization
  • Deep root feeding (soil injection)
  • Soil samples for diagnosis of a disease
  • Trunk injections

Do you already have sickly trees and shrubs in your garden? Our thorough treatment process will eliminate the main culprits and return your plants to a vibrant, ailment-free state. We serve Littleton, Golden, Broomfield, and other nearby areas in Colorado.


Learn About Our Plant Health Care Treatment Process

An accurate diagnosis is the first step to returning plants to their original health. If your plant seems unhealthy, we will conduct a soil test that determines the source behind your sick trees or shrubs. Then, we apply the appropriate treatment (and perform trunk injections to boost resistance, if necessary).

For infestations, our team of plant health care experts will quickly identify the type of insect and the best pesticide to use. We spray it on the affected plants to cover every surface area and eliminate unwanted guests.


An Ounce of Prevention is Worth a Pound of Cure

When trees and shrubs don’t receive the appropriate amount of nutrition, they become much more susceptible to pests and diseases. Our team will enrich your soil with fertilizers to make up for any deficiencies. Unlike other plant health care services, we use a special in-house mixture that provides better prevention results.

Our company also provides deep root feeding, which is basically a “booster shot” for your trees and shrubs. The process involves injecting nutrients directly into a plant’s root ball. We recommend having it done twice a year in spring (between April and May) and fall (once every leaf has fallen off).

Early detection of harmful insects and diseases can save your plants from dealing with a full-blown infestation or infection. Here are common ones you should watch out for in Colorado:

Insects that Attack Trees

Emerald ash borer tree pest near Castle Pines, Colorado.
  • Emerald Ash Borer. This bright green insect attacks Ash species. Early infestation symptoms include leafy shoot growths on the trunk’s base and dead branches at the plant’s top.
  • Aphids. These small, pear-shaped insects can come in hues of green, orange, red, brown, and gray. They suck on plant juices and cause foliage to become sticky and distorted.
  • Pine Beetle. This dark-brown beetle attacks bristlecone, limber, pinyon, ponderosa, and other pines. Infected trees typically turn yellowish-red then progressively rust-colored.
  • Ips Beetle. This small, dark-brown beetle makes small holes in the bark and leaves sawdust on the surface. It usually attacks stressed Spruce or Pine trees.
  • Ash/Lilac Borer. The light-brown larvae create burrows in young, stressed Ash trees, which can cause severe limb damage.

Tree Diseases

Apple scab tree disease showing on leaves near Aurora, Colorado.
  • Apple Scab. This fungal disease leaves olive-green or pale yellow spots on a leaf’s upper surface and dark, velvety spots underneath.
  • Fireblight. This bacterial disease targets Mountain Ash, Hawthorn, Pear, Peach, and Apple. Base twigs become dark and dry, eventually developing cracks and a deep rust hue.
  • Dutch Elm. Dutch Elm is a rarer disease that kills American Elms, exhibiting early symptoms of yellowing and wilting leaves that progressively curl up and turn brown over time.
