Fluoride or Chlorine in Tap Water Certain plants, like spider plants and dracaenas, are sensitive to chemicals in tap water, which can accumulate in the soil and cause leaf tips to turn brown.
Inconsistent Watering Both overwatering and underwatering stress plants, leading to dehydration or root rot, which can manifest as dry, brown tips on the leaves.
Low Humidity Levels Indoor plants, especially tropical varieties, struggle in dry air, causing moisture loss from leaves and leading to brown, crispy edges.
Salt or Fertilizer Buildup Excess fertilizer or naturally occurring salts in soil can create a toxic environment for roots, resulting in browning leaf tips as the plant struggles to absorb water properly.
Root Bound Issues When a plant outgrows its pot, roots become compacted, restricting nutrient and water uptake, which can cause the tips of leaves to dry out and turn brown.
Direct Sunburn Too much direct sunlight can scorch leaves, especially for shade-loving plants, leading to browning tips and patches of damage.
Pest Infestation Tiny pests like spider mites and thrips suck moisture from leaves, weakening plants and causing browning tips as an early sign of infestation.
