Yard Rescue | Aspen Treatment Plan Update
After consulting with a Wilbur Ellis chemical rep, we landed on a treatment plan for the struggling quaking aspens: OxiPhos and Link Deep Root.
OxiPhos reads like a powerhouse. Its active ingredients—hydrogen peroxide and mono- and di-potassium salts of phosphorous acid—give it a dual punch. The hydrogen peroxide helps kill off pathogens, while the phosphorous (in the form of phosphite) acts as an immune booster, helping the tree fight off systemic infections from within.
To support recovery, we’re also applying Link Deep Root, which is designed to promote vigorous root health—exactly what these trees need to bounce back from the edge.
Since the leaves aren't showing signs of surface diseases like powdery mildew, we’re fairly confident that the issue is systemic rather than foliar. This approach targets that kind of problem directly.
A quick but critical reminder: Always read the label.
It’s not just about staying within legal use—it’s also about preventing unintended chemical interactions. In this case, the OxiPhos label specifically warns against mixing it with products containing metal ions. Link Deep Root contains iron, an essential plant nutrient, but one that doesn’t play nicely with OxiPhos.
To avoid causing more harm than good, I’ll be applying each product separately, using a simple soil drench technique with a 5-gallon bucket. I plan to leave a week or two between applications to give the trees time to absorb the treatment and avoid any negative interactions.
More updates to come as we monitor their progress.
