A flat, flour-like white coating that spreads across leaf surfaces is usually powdery mildew. Learn how to tell it from mealybugs, hard water residue and dust, then fix it with better light and airflow and, if needed, a houseplant-labeled spray.

Round brown spots with yellow halos that keep appearing on wet leaves usually mean leaf spot disease. Here's how to rule out sunburn, cold damage, edema and fertilizer burn, and a treatment that works whether the cause is fungal or bacterial.

Silvery, scraped-looking patches dotted with tiny black specks usually mean thrips. Confirm them with a white-paper tap test and a sticky trap, then rinse and spray every 5-7 days for at least 4-6 weeks, because part of their life cycle happens in the soil.

Small brown, tan or white bumps lined up along stems and leaf veins are usually scale insects. Confirm them with a fingernail test, scrape them off, then spray oil or soap weekly for 4-6 weeks to catch the crawlers that keep hatching.

Tiny white bugs in houseplant soil are usually springtails or soil mites, and both are harmless. Use a 10-second jump test to tell them apart, let the soil dry more between waterings, and learn the signs that point to root mealybugs instead.

Identify bugs on indoor plants by what you actually see: webbing, white fluff, brown bumps, sticky leaves, silver streaks, twisted new growth or tiny bugs in the soil. Match the sign to the pest, confirm it, and know how urgent it is.

Small black flies hovering around your plant's soil are almost always fungus gnats, and constantly wet potting mix is the cause. Let the soil surface dry, trap the adults and treat the larvae with Bti for 3-4 weeks.

White cottony clumps in the leaf joints are usually mealybugs. Confirm them with a quick squash test, dab them with rubbing alcohol, then treat weekly until you've gone several weeks without finding a single one.

Fine webbing, pale pin-prick speckles and a dusty, faded look usually mean spider mites. Confirm them with a 10-second paper tap test, then rinse and spray on a 5-7 day schedule for at least 4 weeks to break their life cycle.

Scorched leaves, bleached spots and crispy edges, these are sunburn symptoms not watering problems. Here's how to recognize and fix sun damage on houseplants.

Drooping leaves, dry soil, crispy edges, your plant is parched. Unlike overwatering, underwatering is usually reversible with quick action. Most plants bounce back within hours of a good drink.

A drooping plant is begging for help but the cause could be thirst, overwatering, temperature shock, or transplant stress. The solution depends entirely on the diagnosis here's how to tell.

Your plant has been the same size for months. No new leaves, no visible progress. The causes usually come down to light, roots, or season and most are fixable with the right adjustments.

"Water every Sunday." "Give it a cup of water." "Mist daily." Common watering advice is often wrong. Here's what actually matters and it's not your calendar.

For most houseplants, soil should be moist for 5-7 days and ready for water again by day 7-10. Here's the healthy drying time for monstera, pothos, snake plants and 9 other common plants, plus what to do when soil stays wet too long.

A tangled mass of circling roots needs careful handling, rush it and you'll damage your plant. Here's how to safely repot a root-bound plant and encourage healthy new growth.
