Harry, the Why Guy
Most garden problems make sense once you know what’s causing them, and that is the part I focus on.
I have a degree in Landscape Management and over 15 years of hands-on growing, in small city balcony containers and large perennial borders alike.
I use basic plant science to explain why plants behave the way they do, and I keep it in plain words with steps you can actually follow.

Most of my work starts with a why. Why gravel in a pot keeps roots wetter, why yellow leaves rarely need more fertilizer, and why saved squash seeds do not always come back the same.
I answer those questions here in plain words, with steps that actually work.
