Quick Home Testing Options
A basic soil test for hydrangeas from a garden center can give you a rough pH reading. They’re helpful, but they’re not always super precise.

Track pH, bloom color, fertilizer, and amendments. I know, I know, it sounds nerdy, but this is exactly how I figured out why one plant stayed blue and its sister plant went lilac.
Once you know your number, you can actually fix it safely, and that’s what the next section is all about, so hit next below.
