Check whether it is still changing
Compare a photo with the leaf a few days later. Old dead tissue remains brown even after the cause is corrected.
Topic
A dry point, a sun-facing patch, and a soft spreading lesion need different checks. Choose the shape of damage before changing care.
Compare a photo with the leaf a few days later. Old dead tissue remains brown even after the cause is corrected.
What you may see: Dry browning begins at a point or edge.
Next check: Check root-ball moisture, heating airflow, and fertilizer deposits. Water quality matters for some plants, including spider plants and dracaenas.
What you may see: Tan papery damage appeared after stronger sun or handling.
Next check: Filter the damaging exposure and retain green leaf tissue.
What you may see: Lesions enlarge, look water-soaked, or appear on neighboring leaves.
Next check: Separate the plant and keep foliage dry while identifying the cause. A halo alone cannot name a disease.
What you may see: Silver streaks, pale dots, black specks, or webbing.
Next check: Inspect both leaf surfaces for thrips or mites.

Check the root ball, fertilizer history, water source, and air near the leaves. Brown tips are permanent, but the cause of fresh tip burn can be corrected.

Feel the root ball before watering. Dry soil, wet roots, and a dry center after repotting can all leave a peace lily limp.

Check for a dry root ball, wet decay, pests, or a recent temperature or light change. Follow the matching rescue route and keep healthy tissue.

Use the spot’s location, texture, and change over time to decide whether to check roots, exposure, pests, or leaf disease.

Check the same pot by soil depth and weight. Ferns, foliage plants, and drought-tolerant plants need different amounts of drying between waterings.

Timing narrows the cause: sudden curl in a dry pot, midday curl near hot glass, a leaf that stays rolled, or new growth opening distorted.

Normal nighttime leaf movement changes the leaf’s angle. Persistent rolled blades call for a moisture, heat, humidity, and mite check.

Use the mark’s starting point, texture, and rate of change to choose between watering, salt buildup, sun damage, pests, and a closer disease check.

Check new center leaves, water quality, fertilizer use, and the thick storage roots before deciding how to fix brown tips.

Check recent moves, wet or dry roots, and sticky pest residue to find why a rubber plant is losing leaves.

Feel the leaf and the center of the rosette to separate sun-related color changes, dry scars, cold damage, and soft rot.
