Thought deep root feeding was just a way to sell me stuff till I tried it on a dying red maple in Fort Wayne
A client had this red maple that was maybe 40 percent dead and I told her to just plant a new one, because I figured fert spikes and liquid feed were mostly a cash grab. I gave in and did a deep root feed with a soil needle at 12 inches, 18 gallons of mix, and by August she had new growth on branches I thought were done. Has anyone else had a tree come back like that, or did I just get lucky with the timing?
That part about "new growth on branches I thought were done" is the wildest thing to see in person, hard to believe it until it happens to you. I used to roll my eyes at deep root feeding too, figured it was just a way to pad the invoice and the tree was gonna do what it was gonna do either way. Then I had a similar deal on a willow oak that was looking rough, soil was hard as a rock and the roots weren't getting anything down deep. We fed it right and by the next season it pushed out leaves all over wood I'd already written off. The needle at 12 inches is the whole trick, you're getting water and food past that top layer where it just runs off or sits there. Timing matters some but honestly I don't think you got lucky, I think you actually fixed the problem. I was wrong about it being a cash grab, sometimes the roots just need help getting to what they can't reach.
