Garden plant problem guides
What is wrong with this plant?
Choose the plant, then start with the symptom in front of you. Each guide turns visible evidence into practical checks for water, drainage, light, weather, pests or seasonal stress—without assuming one climate fits every garden.

How this encyclopedia works
A smaller useful answer beats fifty copied ones.
Pages are built only where Garden Sage has reviewed, source-linked plant knowledge. We combine that evidence with conditions you can inspect in your own yard, patio or container and show the original horticultural source.
These checks help narrow a plant problem; they do not claim certainty from a symptom alone.
Still not sure what’s wrong?
Take a photo and ask what to check.
Choose “Help a struggling plant” when Garden Sage asks what you need. Add a clear photo and say what changed. Your saved care history adds context.
