The Houseplant Clinicjohnsonkalistan.xyz

What's wrong with my plant? Start with the plant.

A plain-English reference library of houseplant problems, organized by species — because a yellow leaf means one thing on a monstera and something else entirely on a snake plant. Each guide gives you what you're seeing, the likely causes in order, the checks that tell them apart, the fix step by step, and an honest line on when it's time to let the plant go.

Find your plant

Type the plant, or what it's doing — try “yellow leaves”, “mushy”, “drooping”, “brown tips”, “leggy”, or “not blooming”.

The first batch

Seven species, each with the problem their owners search for most.

How every diagnosis is built

One formula, followed the same way on every page.

01

What you're seeing

The symptoms, described the way they actually look on the plant in front of you — not in textbook language.

02

Causes, in order

The likely culprits ranked most to least likely for this species, so you check the probable ones first.

03

How to confirm

Simple hands-on checks — soil moisture, root colour, a gentle tug — that separate one cause from another.

04

The fix, step by step

The rescue, in the order you'd actually do it, with nothing stronger than household tools.

05

When to stop

The honest line: the signs a plant is past saving, when to toss it, and what (if anything) can be propagated from what's left.
