Orchid Problems
Phalaenopsis spp. / Orchidaceae
Orchids are epiphytic plants that thrive on bright indirect light, chunky bark-based mix, and a distinct dry period between waterings — overwatering and root rot are by far the most common ways orchids decline.
All Orchid Problems
⚠ CriticalOrchid — Root Rot in Orchids
Roots turn brown, mushy, and hollow rather than firm and plump, often with a foul smell, and the plant may wobble loosely in its pot.
⚠ CriticalOrchid — Crown Rot in Orchids
The centre of the plant (the crown, where leaves emerge) turns black, soft, and mushy, and can kill the entire plant if not caught early.
⚠ CriticalOrchid — Bacterial Soft Rot on Orchid Leaves
A water-soaked, translucent spot appears on a leaf and spreads rapidly, turning brown-black and soft, sometimes with a distinct foul smell.
⚠ ModerateOrchid — Fungal Leaf Spot on Orchids
Small, circular, dark spots with a yellow halo appear on leaves, sometimes merging into larger dead patches over time.
⚠ MinorOrchid Not Reblooming
The plant stays healthy with good leaves but fails to produce a new flower spike season after season, or spikes form but never open into flowers.
⚠ ModerateOrchid — Bud Blast — Orchid Buds Dropping Before Opening
Developing flower buds turn yellow or shrivel and drop off the spike before ever opening, sometimes affecting the entire spike at once.
⚠ ModerateOrchid — Wrinkled or Pleated Leaves on Orchids
Leaves develop a wrinkled, accordion-like, or pleated texture rather than staying smooth and firm, sometimes accompanied by a dulled colour.
⚠ MinorOrchid — Yellowing Leaves on Orchids
A leaf turns yellow, sometimes starting from the base and progressing along its length, before eventually dropping.
⚠ ModerateOrchid — Scale Insects on Orchids
Small, immobile brown or tan bumps attach to leaves and stems, secreting honeydew and weakening the plant over time.
⚠ ModerateOrchid — Mealybugs on Orchids
White, cottony masses cluster in leaf axils, on flower spikes, and around the base of leaves, secreting honeydew and weakening the plant.
⚠ ModerateOrchid — Spider Mites on Orchid Leaves
Fine yellow stippling spreads across leaves, with fine webbing visible in heavier infestations, especially in dry indoor air.
⚠ MinorOrchid — Aphids on Orchid Flower Spikes
Small soft-bodied insects cluster on tender new flower spikes and buds, sometimes causing distorted bud development and sticky honeydew residue.
⚠ MinorOrchid — Sunburn on Orchid Leaves
A bleached, yellow-white, or brown patch develops on the leaf, usually on the side that received direct sun exposure, and doesn't recover once damaged.
⚠ ModerateOrchid — Cold Damage on Orchids
Leaves develop translucent, water-soaked patches that turn brown or black after cold exposure, often near a drafty window in winter.
⚠ MinorOrchid — Salt and Fertiliser Buildup on Orchid Roots
A white, crusty residue builds up on the potting medium surface or on roots, and the plant may show root tip burn or reduced vigour despite regular feeding.
⚠ MinorOrchid — Fungus Gnats in Orchid Potting Mix
Small dark flies hover around the plant and potting medium, with larvae in the mix potentially feeding on fine root hairs in already-stressed plants.
⚠ CriticalOrchid — Viral Infection in Orchids
Leaves develop a mottled or streaked pattern of light and dark patches, sometimes with a break in flower colour pattern, and overall vigour declines gradually.
⚠ MinorOrchid — Keiki (Baby Plantlet) Formation on Orchid Spikes
A small plantlet with tiny leaves and sometimes roots forms along the flower spike or at the base of the plant, rather than another flower.
⚠ MinorOrchid — Understanding Green vs. Silvery Orchid Roots
Growers are often uncertain whether their orchid's root colour indicates a watering problem, since roots visibly change colour between watering and drying out.
⚠ MinorOrchid — Stress and Decline After Repotting an Orchid
The plant looks wilted, drops leaves, or generally struggles for several weeks after being repotted, even though the repotting itself seemed to go well.
⚠ MinorOrchid Growing Roots Outside the Pot
Thick, silvery-green roots emerge from the potting medium and grow outward into open air, sometimes extending well beyond the pot's rim.
⚠ MinorOrchid — Thrips on Orchid Flowers
Silvery streaks and small dark specks appear on flowers and leaves, with flowers sometimes showing distorted or discoloured patches.
