Tell us the symptom. We’ll find the cause.
Every guide opens with a quick-diagnosis table: match what you’re seeing, see how likely each cause is, and get the exact fix. No 300-word filler, no forum guesswork.
Four ways a plant tells you something’s wrong
Not sure where to begin? Start with the kind of problem you’re seeing — each hub links down to every specific diagnosis beneath it.
Plant leaf problems
Leaves are where plants show distress first. Diagnose yellowing, curling, spots, holes and browning edges — find the cause and the exact fix.
ExplorePests and what they do to plants
Aphids, spider mites, slugs, sawfly, whitefly, vine weevil and more. Identify the pest from the damage it leaves, then treat it the right way.
ExplorePlant diseases
Blight, black spot, powdery mildew, rust, mosaic viruses and rots. Tell fungal, bacterial and viral diseases apart and control them before they spread.
ExploreWatering and nutrient problems
Over-watering, under-watering and nutrient deficiencies cause more plant deaths than pests and disease combined. Learn to read the signs and correct them.
ExploreHow a Leaf & Cause guide works
The same dependable structure on every page — the part that forum threads and thin AI farms never give you.
Match the symptom
A quick-diagnosis table lists every likely cause with a colour-coded likelihood and the single tell-tale sign that separates it from the others.
Confirm, then fix
Each cause has a short “how to confirm it” checklist and a numbered fix — specific actions, not vague advice.
Still stuck? Follow the path
A “still not sure?” decision path sends you to the right answer when two causes look alike.
Most answers to “why is my plant doing this?” are buried in forum threads. We lead with the diagnosis table — the cause, how likely it is, and the exact fix.
