ArbRX professional tree care and diagnostics from ISA Certified Arborists- proudly serving Lethbridge and surrounding communities
Healthy Trees Start Below the Surface.
Strong, beautiful trees don’t happen by accident. In Southern Alberta’s tough climate — with its hot summers, strong winds, and dry spells — even mature trees can struggle to stay healthy.
That’s where ArbRx by Timberline Arborists comes in.
Our specialized plant health care services focus on what’s happening below the bark. We diagnose and treat nutrient deficiencies, pest infestations, and diseases using targeted, science-backed solutions — designed for the soils, trees, and conditions right here in Lethbridge and the surrounding region.
Whether your trees are showing signs of stress or you simply want to keep them in peak condition, we can help.
Common Signs Your Trees Need Help
• Leaves turning yellow or browning early
• Dead branches or thinning canopy
• Unusual spots, oozing, or holes in bark or leaves
• Poor growth despite regular watering
• Sudden dieback or leaf drop
These symptoms are more than cosmetic — they’re signs your trees could be in decline. Early action is key to saving them.
