What’s curling my elm leaves? Meet the elm leafcurl aphid (Eriosoma americanum) — tiny pests causing big distortions! These aphids feed inside newly emerged elm leaves, triggering tight curling, blistering, and that telltale purplish swelling. By the time you see damage, colonies are already well established and protected inside the leaf. What you’re seeing here: - Dense aphid colonies - Waxy exuviae (shed skins) - Early signs of honeydew buildup What I recommend for treatment: 1. Promote tree health such as water, mulch, no excess nitrogen 2. Avoid broad spectrum insecticides that kill natural predators like ladybugs 3. For high-value urban trees: TreeAzin injections — now is the perfect window for systemic treatment Not all pests need to be sprayed — smart timing, healthy trees, and the right tools can make all the difference. #ArboristLife #IPM #ElmAphid #TreeHealth #UrbanForestry #SouthernAlbertaTrees #TreeAzin #PestID #PlantHealthCare #yqltrees

Not every tree can be saved. This birch was too far gone — canopy loss, extensive borer damage, and decline past the point of recovery. When is it too late to treat? 🌿 Over 30% canopy loss 💀 Major dieback in the crown At that stage, removal is the safest and most responsible choice. The key is early detection. If your birch is thinning or showing signs of stress, don’t wait. 📍Serving Lethbridge & area 📞 Call now for a tree health checkup #BirchBorer #TreeCareTips #ArboristLife #TreeRemoval #LethbridgeTrees #TreeRx #TimberlineArborists

🔍 What’s inside these rolled-up ash leaves? If you unroll one and find little brown “coffee grounds,” you’ve likely found the work of the ash leaf cone roller—a tiny caterpillar that rolls leaves to feed and hide. While the damage is mostly cosmetic, a heavy infestation year after year can stress your tree. If your ash is looking rough, we can help identify the issue and recommend the right treatment—whether that’s a targeted spray or a deep root feeding to boost its health. 📍 Serving Lethbridge and area | Certified Arborist 📞 Call or DM to book your tree checkup #AshTree #TreePests #LethbridgeTrees #Arborist #TreeHealth #YQL #AshLeafConeRoller #TreeCare

See those brown, dome-shaped bumps along the branch? That’s scale—specifically, pine needle scale—feeding on sap and slowly draining the tree’s energy. These pests often go unnoticed until needles yellow or drop, and by then, the damage is done. If you spot anything like this on your pine, it’s time to act. Treatments vary by season, but early intervention is key to protecting the health and longevity of your tree. #TreeCareTips #LodgepolePine #ScaleInsects #TreePests #ArboristAdvice #TimberlineArborists #ArbRx #PlantHealthCare #TreeEducation #TreeProblems #YQLArborist

Ever seen fine webbing on spruce needles? It’s not from spiders — it’s actually one of the first visible signs of spider mites, a tiny pest that feeds on needle tissue and can severely weaken the tree over time. Early damage looks like yellow stippling or dull needles. If left untreated, the tree can suffer dieback, needle drop, or even death in severe infestations. The good news? Spider mites are manageable when caught early — and that’s exactly what this post is for. We’re seeing signs in the Lethbridge area already, so now’s the time for inspections and proactive treatment. #SpiderMites #TreeCareTips #SpruceTreeHealth #PlantHealthCare #TimberlineArborists #LethbridgeTrees

They wanted to cut it down… but it didn’t need to die.” Another arborist recommended removing this mature elm because a tenant had chopped away some bark with an axe. But when we inspected it, the tree was healthy, thriving, and absolutely worth saving. At Timberline, we’re not just about removals — we’re about preservation. We take the time to truly assess what’s going on before making any irreversible decisions.
