Brown Spots on Leaves

Brown spots on leaves can result from fungal infections, bacterial issues, watering problems, or physical damage. The pattern of spots helps identify the cause.

संभावित कारण

Fungal Leaf Spot

Why: Fungal spores land on wet leaves and develop into brown spots, often with a yellow halo.

Signs to check: Circular brown spots with yellow margins, often on lower leaves first, spots may have concentric rings.

Bacterial Leaf Spot

Why: Bacteria enter through leaf pores or wounds, causing water-soaked spots that turn brown.

Signs to check: Irregular, water-soaked spots that dry to brown, may have a yellow border, can be slimy.

Inconsistent Watering

Why: Alternating between very dry and very wet stresses the plant, causing leaf damage.

Signs to check: Random brown patches, especially on leaf edges and tips, soil moisture fluctuates greatly.

Sunburn

Why: Direct sun on sensitive plants causes localized brown, dry patches.

Signs to check: Brown spots only on the side facing the light source, spots are dry and papery.

क्या जाँचें

  • 1
    Examine the shape and pattern of the spots — circular or irregular?
  • 2
    Check if spots have a yellow halo or water-soaked appearance
  • 3
    Review watering consistency over the past few weeks
  • 4
    Assess light exposure — could it be sunburn?
  • 5
    Check if spots are spreading to other leaves

आगे क्या करें

  • Remove severely affected leaves to limit spread
  • Avoid getting water on the foliage when watering
  • Improve air circulation around the plant
  • Maintain consistent watering habits
  • For fungal issues, a copper-based fungicide may help as a last resort

कब मदद लें

  • Spots are spreading rapidly across the plant
  • Large portions of leaves are covered in brown patches
  • Spots appear slimy or have a foul odor (bacterial infection)

मुख्य बात

The pattern and texture of brown spots are important clues. Fungal spots tend to be circular; bacterial spots tend to be irregular and water-soaked.
