Why Are My Orchid Leaves Turning Yellow?
Disease: Root Rot ( leaves turning yellow)
Cause: Overwatering or poor drainage
Cure:
Yellowing leaves are a classic sign of root rot, which occurs when roots stay wet for too long and start to decompose. To save your orchid, remove it from its pot, trim all soft or blackened roots, and repot using a fast-draining orchid mix. Water only when the medium is nearly dry, and make sure your pot has proper drainage holes.
What Are the Black Spots on My Orchid?
Disease: Black Rot (Pythium or Phytophthora)
Cause: Fungal infection due to excess moisture
Cure:
Black rot causes dark, mushy spots that spread rapidly, especially in warm, humid conditions. Start treatment by isolating the infected orchid to protect others.Using sterilised scissors, cut off all of the rotting tissue and dispose of it. Apply a broad-spectrum fungicide to the healthy parts and improve air circulation. Always avoid letting water sit on leaves or in crevices.
Why Are My Orchid’s Flowers Deformed?
Disease: Orchid Viruses (e.g., Cymbidium Mosaic Virus)
Cause: Spread through contaminated tools or pests
Cure:
Distorted flowers with streaks or discoloration could indicate a virus. Orchid viral infections are unfortunately incurable. The best approach is prevention—sanitize your tools, isolate new plants, and avoid handling multiple orchids without cleaning in between. If you confirm a viral infection, it’s best to discard the plant to protect your entire collection.
What’s Causing My Orchid’s Leaves to Pucker or Wrinkle?
Disease: Dehydration or Root Damage
Cause: Poor watering or root rot affecting water absorption
Cure:
Wrinkled leaves are a sign that your orchid isn’t taking up water properly, often due to damaged roots. Examine the roots of the plant after carefully removing it from its pot.. Cut away anything that feels soft or mushy. After repotting, soak the plant in water for 30 minutes and increase ambient humidity by misting lightly or placing a tray of water nearby.
Why Do My Orchid’s Leaves Have Silvery Webbing?
Disease: Spider Mites
Cause: Dry indoor air and poor airflow
Cure:
Tiny spider mites feed on leaf sap and leave behind silvery webs. While they’re hard to see, their damage is obvious. Begin treatment by wiping down leaves with a damp cloth. Spray neem oil or insecticidal soap every few days for at least two weeks. Increasing humidity and keeping plants dust-free will help prevent future infestations.
What Are These Sticky Drops on My Orchid?
Disease: Scale or Aphids
Cause: Insect pests feeding on sap
Cure:
Sticky substances, or “honeydew,” signal the presence of scale insects or aphids. These bugs hide under the undersides and joints of leaves. Dab the bugs directly with a cotton swab dipped in rubbing alcohol. Follow up with neem oil sprays. Check nearby plants, as these pests move fast and can infest your entire collection if left unchecked.
Why Are My Orchid’s Buds Dropping Prematurely?
Disease: Bud Blast
Cause: Sudden changes in temperature, light, or humidity
Cure:
Bud blast happens when flower buds drop off before blooming, usually from environmental stress. Avoid moving the plant, especially during blooming. Keep temperature, humidity, and lighting conditions stable. Water consistently and avoid drafts. Adding a humidity tray or using a humidifier can also help prevent bud blast in dry indoor environments.
What’s Causing Brown Spots on My Orchid Leaves?
Disease: Sunburn or Bacterial Brown Spot
Cause: Direct sunlight or bacterial entry through wounds
Cure:
Brown, dry spots on leaves may be due to too much direct sunlight or bacterial infection.Place your orchid in an area that receives plenty of indirect light. If the spots are soft or ooze, they’re likely bacterial. Cut out affected tissue and apply bactericide. To avoid moisture accumulation on leaves, water in the morning and at the base.
Why Are There White Fluffy Patches on My Orchid?
Disease: Mealybugs
Cause: Stagnant air and sweet plant sap attract pests
Cure:
Mealybugs gather in the joints and roots of leaves and resemble cotton balls.Gently brush or dab them away with a cotton swab dipped in alcohol. Spray neem oil weekly for a month to eliminate all life stages. Improving airflow, wiping leaves regularly, and quarantining new plants can prevent reinfestation.
What’s This Mushy Brown Area at the Base of My Orchid?
Disease: Crown Rot
Cause: Water pooling in the leaf crown
Cure:
Crown rot can kill orchids quickly if untreated. It starts with a soft, brown center where the leaves meet. Use sterile scissors to remove rotted tissue and tilt the orchid to dry the crown area completely. Apply hydrogen peroxide or a fungicide. Always water in the morning and avoid getting water in the crown when possible.
Final Tips to Keep Your Orchid Thriving
Healthy orchids need a balanced mix of light, water, air, and nutrients. The key to preventing diseases is maintaining proper care routines and spotting issues early. Always use sterilized tools, avoid overwatering, and inspect your orchids weekly for pests or signs of infection. With attention and care, your orchids can flourish and bloom beautifully for years to come.
