Houseplant problem guides by plant

Start with the plant name when the same symptom could mean different things. Each page explains what the plant often struggles with, how it handles water and light, and what to look at first. The library now covers 40 common houseplants and links each plant to symptom-by-symptom guides.

Monstera houseplant

Monstera

Aroid

Check a monstera’s root-ball moisture and newest leaves. Its climbing stem needs support; leaf size and splits also change with maturity, so they do not measure light on their own.

Peace Lily houseplant

Peace Lily

Tropical foliage

A peace lily can wilt over dry soil or damaged roots in wet soil. Check the root ball before watering, and compare new growth with old yellow leaves or brown tips.

Fiddle Leaf Fig houseplant

Fiddle Leaf Fig

Ficus

Compare fiddle leaf fig marks by texture, exposure, and whether they are enlarging. Check the root ball when spots come with wilt, yellowing, or leaf drop.

Pothos houseplant

Pothos

Aroid vine

Follow a troubled pothos vine back to its base. One damaged vine, several yellowing vines, and long weak new growth need different checks.

Snake Plant houseplant

Snake Plant

Drought-tolerant succulent foliage

Snake plants store water in leaves and rhizomes. Firm old marks differ from new wet-soft damage at a leaf base, especially after cold exposure or persistent wet soil.

Calathea houseplant

Calathea

Prayer plant

Calatheas need even root-ball moisture and protection from hot airflow. Normal daily changes in leaf posture differ from a blade that stays tightly rolled; check patterned undersides for mites.

ZZ Plant houseplant

ZZ Plant

Drought-tolerant rhizome plant

ZZ plants store water in underground rhizomes. Check stalk and rhizome firmness when growth leans or yellows, and account for cultivar colors in new growth.

Succulents houseplant

Succulents

Succulent

These guides focus on fleshy desert-type succulents. Compare wrinkled leaves over dry mix with wet-soft tissue, and use a propagation method suited to the species.

mushy leaveswrinkled leavesleggy growthroot rot
Spider Plant houseplant

Spider Plant

Grassy foliage

Spider plants have thick pale storage roots. Brown tips can involve salts, fluoride, repeated drying, or root damage; a crowded pot matters when it becomes difficult to water evenly.

Rubber Plant houseplant

Rubber Plant

Ficus

For rubber plant leaf loss, compare recent exposure changes with root-ball moisture and check stems for scale. Firm partly green leaves can remain while the plant recovers.

leaf dropyellow leavesbrown edgesroot stress
Aloe Vera houseplant

Aloe Vera

Succulent

For aloe, separate firm bronze coloration, dry dead patches, and translucent soft tissue. Check the crown before attempting rescue; healthy offsets are more reliable than detached leaves.

Heartleaf Philodendron houseplant

Heartleaf Philodendron

Aroid

These guides cover vining heartleaf philodendrons. Follow affected leaves along the vine, inspect nodes and leaf sheaths, and check the root ball before changing watering.

Chinese Money Plant houseplant

Chinese Money Plant

Pilea

Compare pilea’s newest round leaves with old lower growth. Cupping direction alone cannot identify the cause; use root-ball moisture, exposure, and stem firmness.

yellow leavesdroopingcurling leavesbrown spots
Jade Plant houseplant

Jade Plant

Succulent

Jade stores water in leaves and stems. Thin wrinkled leaves over dry mix can need water; translucent leaves or a soft trunk over wet mix need a root inspection.

soft leavesyellow leavesleaf droproot rot
Anthurium houseplant

Anthurium

Aroid

Anthuriums need air around their roots as well as moisture. Identify whether you grow a flowering hybrid or a foliage species before treating a lack of showy blooms as a problem.

yellow leavesbrown tipsbrown spotsno flowers
Phalaenopsis Orchid houseplant

Phalaenopsis Orchid

Epiphytic orchid

Judge phalaenopsis by root texture and the condition of its bark or moss. Check the center of the pot and keep water out of the leaf crown.

yellow leavesroot rotlimp leavesbrown spots
Boston Fern houseplant

Boston Fern

Fern

Boston fern fronds can brown after the root ball dries hard or beside hot airflow. A firm crown and green fiddleheads show what can regrow after damage.

brown tipscrispy leavesyellow leavesleaf drop
Bird of Paradise houseplant

Bird of Paradise

Large tropical foliage

Bird of paradise needs room for its large leaves and strong light. Clean green splits can remain; curl and wilt require checking moisture inside the large root ball.

yellow leavescurling leavesbrown edgesleaf splits
Dieffenbachia houseplant

Dieffenbachia

Tropical cane foliage

Check the dieffenbachia cane when leaves wilt or yellow. Firm cane can support recovery; wet-soft bases need inspection. Wear gloves when cutting its irritating sap.

yellow leavesdroopingbrown tipssoft stems
Dracaena houseplant

Dracaena

Cane foliage

Dracaena tips can burn from water quality, salts, drought, or damaged roots. Check the cane and root texture when lower leaves yellow or drop.

brown tipsyellow leavesleaf droproot rot
English Ivy houseplant

English Ivy

Trailing foliage

Inspect indoor ivy undersides for mites when leaves look gray, speckled, or crisp. Also check for a dry root-ball center and hot airflow around hanging vines.

crispy leavesyellow leavesspider mitesleaf drop
String of Pearls houseplant

String of Pearls

Trailing succulent

Check the string-of-pearls crown as well as trailing beads. The top of the pot needs light, and shriveling over wet mix can indicate root loss rather than thirst.

mushy leavesshrivelingroot rotleggy growth
Hoya houseplant

Hoya

Semi-succulent vine

Hoya species differ in leaf thickness, watering needs, and flowering age. Check root-ball moisture for wrinkles and retain living flower spurs on species that rebloom from them.

yellow leaveswrinkled leavesroot rotno flowers
Schefflera houseplant

Schefflera

Tropical tree

Inspect schefflera stems and leaf joints when leaves drop or turn sticky. Scale and mealybugs can hide among leaf clusters; also compare moisture and recent moves.

Parlor Palm houseplant

Parlor Palm

Palm

Parlor palms replace fronds slowly. Keep green foliage and growing points intact while checking water delivery, salt deposits, and mites among the fine leaflets.

Areca Palm houseplant

Areca Palm

Palm

Check inner areca fronds for mites and the center of crowded root balls for uneven moisture. One old frond differs from several canes losing new growth.

Money Tree houseplant

Money Tree

Tropical tree

A braided money tree contains several trunks. Trace declining leaves to their trunk and check its base for softness; dark bark alone does not establish rot.

yellow leavesleaf droproot rotbrown tips
Nerve Plant houseplant

Nerve Plant

Humidity-loving foliage

Fittonia can wilt sharply as its small root ball dries. Repeated collapse damages leaves, while wilt over wet mix needs a root check rather than another watering.

droopingcrispy leavesbrown tipsyellow leaves
Begonia houseplant

Begonia

Decorative foliage

Cane, rex, wax, and tuberous begonias have different light and growth habits. Compare dry injury with expanding lesions, and distinguish dormancy from a soft crown.

brown spotscrispy edgesleaf dropyellow leaves
Alocasia houseplant

Alocasia

Aroid tuber

Check alocasia’s newest leaf, petiole bases, and undersides. One old leaf can age, but a new leaf does not require the plant to lose an old one every time.

yellow leavesdroopingbrown spotsspider mites
Oxalis houseplant

Oxalis

Bulb-like foliage

These guides concern false shamrock, Oxalis triangularis. Daily leaflet folding is normal; prolonged decline needs checking for drought, rot, or a genuine rest period.

droopingyellow leavesleggy growthleaf drop
Croton houseplant

Croton

Colorful tropical foliage

Croton leaves naturally contain yellow and other colors. Loss of firmness, repeated leaf drop, sticky residue, or mite stippling distinguishes damage from a healthy pattern.

leaf dropyellow leavesbrown tipspests
Tradescantia houseplant

Tradescantia

Trailing foliage

Tradescantia can become bare near the pot as vines age. Improve growing conditions, then use healthy node-bearing tip cuttings to rebuild fullness.

leggy growthbrown spotscrispy leavesyellow leaves
Peperomia houseplant

Peperomia

Semi-succulent foliage

Peperomias vary from thin-leaved to fleshy types. Many common indoor forms have small roots, so fit the pot to the root ball and inspect soft petiole or stem bases.

Ponytail Palm houseplant

Ponytail Palm

Drought-tolerant caudex plant

Ponytail palm stores water in its swollen base. Stable dry tips are a different problem from wet-soft damage in that base; keep the central growing point intact.

Cast Iron Plant houseplant

Cast Iron Plant

Low-light tolerant foliage

Cast iron plants grow slowly and keep old marks for a long time. Compare new leaves and the rate of leaf loss before changing care for one old tip or spot.

yellow leavesbrown tipsbrown spotsslow growth
Aglaonema houseplant

Aglaonema

Tropical foliage

Compare old lower aglaonema leaves with the newest growth. Several yellow leaves, persistent wilt, or a soft cane need checking roots, drainage, and cold exposure.

Yucca houseplant

Yucca

Drought-tolerant cane plant

Indoor yuccas need strong light and a drying period. Check deep in large pots and feel the cane when leaves yellow or a head droops.

Norfolk Island Pine houseplant

Norfolk Island Pine

Conifer-like houseplant

Keep the Norfolk pine’s living leader and green branch tips. Dead branches do not refill; check root-ball moisture and heat exposure before damage spreads.

Christmas Cactus houseplant

Christmas Cactus

Epiphytic cactus

Christmas cactus is a forest cactus with flattened stem segments. Check roots when segments stay limp in wet mix, and keep moisture and temperature steady during bud development.
