"Riccio Tree Care recently trimmed bushes, shrubs, and trees in my yard, and I was impressed by their skill. The crew was efficient, courteous and careful. Their work improved the look of my yard, and the fee was most affordable. I recommend them without reservation. Bob Miller Longmont"

"Tim has ISA (International Society of Arboriculture) certification and.has been trimming trees at my place over the past few years. He does a great job at pruning & shaping my trees to dealing with storm damage, grinding stumps, chipping, and cleaning up the mess before he leaves my residence. As a retired landscape architect, I can appreciate his eye for pruning and shaped my 28 year old trees. I have recommended Tim to several other satisfied customers."

Customers say: Quick response

"I will echo what the other reviewers have written. Very competent, hardworking crew. Completely removed 2 trees - 1 huge leaning pine - and left fences, irrigation, and other landscaping untouched. Ground up the stump in the lawn. Shaped and trimmed three other trees away from contact with powerlines. Amazing to watch the climbers work! Immaculate clean-up afterward. We would hire them again without hesitation!"

"Prompt response and able to do the project the same day and cleaned up everything including old branches at the end of the project. Might have taken a bit more off the branches than I’d like, but I’m no arborist and they certainly removed all the dead/non-leaf branches at a great price."

Arborists FAQs, answered by experts

For effective tree maintenance in Thornton, keep bypass pruners, loppers, a pruning saw, and a pole pruner for safe branch removal. Stock up on tree wrap for winter, burlap for wind protection, and wood chip mulch. Soaker hoses provide efficient watering. Have a first aid kit, tarps for debris collection, horticultural oil for pest control, slow-release fertilizer for alkaline soil, and a pH testing kit to monitor soil health.

Helpful?

As a new homeowner in Thornton, begin with a tree hazard assessment to identify dead or unstable trees and check for local pests like emerald ash borer. Evaluate your irrigation system for efficiency in the dry climate. Apply mulch to conserve soil moisture, prune damaged limbs before winter, and test soil pH. Establish wind barriers for young trees and create a watering plan that aligns with local guidelines.

Helpful?

For tree service projects in Thornton, select drought-tolerant species like Colorado Blue Spruce or Bur Oak, which adapt well to local clay soils. Enhance soil drainage with compost and organic matter, and use wood chip mulch to conserve moisture. Galvanized steel stakes stabilize young trees against wind. Install protective guards to deter wildlife, and choose slow-release, low-nitrogen fertilizers suited for Thornton’s alkaline conditions to support healthy tree growth.

Helpful?

In Thornton, address tree issues immediately if you notice dead limbs, storm damage, pest infestations, or leaning trees, as these can pose safety risks. Schedule routine pruning and mulch application during the dormant season for best results. Plant new trees in spring or fall. Always consider local watering restrictions and weather conditions, and consult a professional for urgent or hazardous tree care situations.

Helpful?

In Thornton, start spring by inspecting for winter injury and early pest activity. During summer, check for drought stress and monitor for common tree pests. In fall, assess tree structure and prepare for winter by adding mulch and securing wraps. Winter is ideal for checking snow or ice damage and ensuring protection remains intact. This routine supports proactive tree care and helps maintain healthy trees year-round.
