Can overwatering cause brown leaf edges?

Brown leaf edges can send anyone into a panic. Once, I watered a peace lily every week like my clock dictated and it was dead within a few weeks. It was not dead when I drowned it, but its roots became saturated, broke down, and became mushy, its nutrient delivery was blocked and the leaves browned like toast. To be exact, overwatering drowns your roots and blocks nutrients. But don't panic, maybe it would be dry air or salt buildup mimicking brown edges. Always check the soil first before freaking out.

Do not confuse thirst for drowning. My snake plant's brown tips had me fooled this time, almost causing me to overwater again, until I used the meter and discovered the soil at the roots was desert-dry. Lift the pots to determine the weight: light is drink, heavy is wait. Seasonal changes require some flexibility; you are going to need to water less when the light is dim in the winter.

Recovery takes MONTHS and, not days. My rescued monstera put out new leaves after 8 weeks of dry soil and 60% humidity. Keep the damaged leaves until new ones come in; they still photosynthesize. Keep track of progress: record watering dates and changes to the leaves. Note any readings of your tools. Consistency will help you rebuild trust with your plant.
