why is my spider plant turning brown

The most common reasons for a spider plant turning brown include improper watering (both overwatering and underwatering), low humidity, chemical buildup from tap water (chlorine or fluoride), over-fertilization, direct sunlight exposure, and sometimes root rot. Overwatering can cause root rot and lead to brown spots and wilting, while underwatering causes dry, crispy leaf tips because the plant is dehydrated. Low humidity can dry out leaves, and chemicals in tap water can build up and damage the roots, showing as brown tips. Exposure to direct sunlight can scorch the delicate leaves, causing browning. Over-fertilization leads to salt buildup in soil, which dehydrates the plant and brown tips appear. Natural aging of leaves can also cause browning of older leaves as a normal life cycle process. To fix brown tips, adjust watering by allowing the soil to dry out slightly between waterings, use filtered or distilled water instead of tap water, increase humidity by misting or using a pebble tray, avoid direct sunlight, reduce fertilization frequency, and trim off brown tips with clean scissors to encourage new growth. If root rot is suspected, repotting with fresh soil after trimming rotten roots is recommended.
