One promise: the symptom in, the cause and fix out.
Leaf & Cause does one thing: it diagnoses plant problems. Not garden inspiration, not product reviews — diagnosis. You arrive with a symptom (“why are my tomato leaves curling?”, “white spots on my courgette leaves”, “hydrangea wilting after planting”) and you leave knowing the likely cause and exactly what to do about it.
Most answers to these questions are scattered across forum threads and thin, padded articles. We think the gardener in a panic deserves better: a structure you can actually use under pressure.
Every guide follows the same shape
A quick-diagnosis table
Every cause for your symptom, each with a colour-coded likelihood and the single tell-tale sign that separates it from the rest.
Confirm, then fix
A short checklist to confirm each cause, followed by a numbered, specific fix — and how to stop it happening again.
A decision path
When two causes look alike, a “still not sure?” path walks you to the right answer.
How we research and review
Every guide is written and reviewed by the Leaf & Cause editorial team against established horticultural sources — principally the Royal Horticultural Society and university extension services — and the sources we leaned on are listed at the foot of each article. Guidance is written specifically for UK growing conditions and seasons.
Our editorial standard is simple: lead with diagnosis, not filler; separate the likely cause from the look-alikes; recommend the smallest safe intervention first; and never tell you to spray, feed or repot before you have confirmed the cause. We revise guides as horticultural guidance and our own field experience evolve.
It is general information, not a substitute for professional advice on a valuable or unusual plant. Always identify a problem before treating it, and follow the label on any product you use.
