Even experienced growers run into issues. The good news: most common plant diseases are easy to treat when caught early.
Leaf spot shows as brown or yellow blotches—remove affected leaves and improve airflow. Powdery mildew looks like white dust—wipe leaves gently and reduce humidity around susceptible plants.
Begin with observation before treatment. Check whether damage is spreading, which leaves are affected first, whether the soil stays wet, and whether you can see insects, webbing, residue, or distorted new growth. Sun scorch, cold damage, fertilizer burn, root stress, and pests can resemble disease, so one symptom rarely proves a cause.
Isolate a plant with a potentially contagious problem and clean tools between plants. Remove severely damaged material only when the plant can tolerate the loss, and discard it away from healthy pots. Improve spacing and airflow, avoid leaving foliage wet overnight, and correct watering or drainage conditions that may have contributed.
Choose a treatment only after narrowing the cause. Follow the product label, test sprays on a small area, protect children and pets, and avoid combining products unless the label allows it. Repeatedly applying a broad treatment without correcting light, water, airflow, or quarantine conditions often leads to recurrence.
Track photos over several days under similar lighting. Stable old damage does not necessarily mean a treatment failed; the useful signs are whether new spots appear and whether new growth is healthy. If a valuable plant declines rapidly or the cause remains unclear, consult a local extension service, nursery, or qualified plant-health professional.
When unsure, open Fylora and use the AI doctor: take a close photo of the affected area and receive a likely diagnosis with clear, step‑by‑step treatment guidance.
