Appreciation post: A stubborn rhododendron in my client's yard in Bellingham made me rethink fertilizer

I kept trying to force-feed it a standard 10-10-10 mix for a full season with zero new growth. My client, an older guy named Frank, finally said, 'Kid, that soil is pure clay, it's just locking it all up.' He was right, I tested the pH and it was a solid 8.2. Anyone else have a plant that forced a total method change on you?

Totally get that. My neighbor's hydrangeas were just sad pink lumps for years. She was using leftover lawn feed on them, the high nitrogen stuff. Switched her to a bloom booster and the next summer they were these insane blue pompoms. Sometimes the fix is stupid simple.

Oh man, that hits home. I had a blueberry patch that just would not thrive, kept throwing standard acidic fertilizer at it. Turns out the previous owner had limed the whole garden bed for tomatoes years ago and the pH was totally wrecked for blueberries. Felt like such a dummy, had to basically replace the topsoil. Plants really do tell you when you're getting it wrong.

Have you ever read that soil pH is kind of like the first domino in plant health? I saw this YouTube short from a master gardener who said most nutrient problems actually start with bad pH, not bad fertilizer. So @leo238's point about bloom boosters makes total sense to me, because the plant might finally access what it needs. Your blueberry story reminds me of a friend who had the same issue with his hydrangeas, white all year until he learned the soil was basically locked up. Take this with a grain of salt, but I swear plants just want us to pay attention to the basics first.
