Both under-watering and over-watering can be detrimental to a houseplant. Different species of houseplants require different soil moisture levels. Brown crispy tips on a plant’s leaves are a sign that the plant is under-watered. Yellowing leaves can show that the plant is over watered. Most plants can not withstand their roots sitting in water and will often lead to root rot.
