Brown leaf tips on houseplants? Record the pattern first
Brown tips and crisp edges can overlap with dry-down timing, room air, water source, fertilizer timing, older-leaf wear, and recent weather. One dry-looking tip does not identify one cause. Before changing water, humidity, fertilizer, soil, or placement together, build a Dry Edge Ledger you can compare over time.
1. Map the brown-tip pattern
Record whether the browning is only on the tip, along the margins, on older leaves, on new leaves, or only on one side of the plant. Photograph one close leaf and one wider view of the same leaf. Pattern matters more than one dramatic crop.
2. Add the whole-plant view
Keep the pot, nearby leaves, and window visible. One older leaf with a dry tip is a different pattern from many leaves crisping at once. Distribution gives the close-up useful context.
3. Check moisture below the surface
Look below the top layer of soil and note whether the pot feels unusually light or still heavy. The goal is not a one-touch diagnosis. It is a truthful record you can compare with the other clues.
4. Record room and water context
Save window direction, vent or fan exposure, heating or cooling, recent hot weather, water source, fertilizer timing, and whether the tips were previously trimmed. These details often explain why a tip pattern looks more severe than the rest of the leaf.
5. Repeat from the same angle
Mark the camera position and repeat after a useful interval. Compare whether the same edges stay stable, expand, or appear on new leaves. Existing damage may remain even when the broader pattern stops spreading.
Choose one cautious next step
Correct one clear issue at a time, such as a severe dry-down pattern or constant vent exposure. Do not trim, fertilize, flush, repot, and change humidity together from one crispy edge. Seek qualified local help when many leaves are declining quickly, stem tissue is soft, or the plant is difficult to inspect safely.

Keep the comparison useful
Use the broader sick-houseplant first pass, compare brown spots on leaves separately from dry margins, and keep a repeatable plant recovery log while you watch the pattern.
