Plants that have received an optimal amount of water will manifest healthy, vibrant green leaves. Indicators of over-watering or under-watering include yellowing leaves, drooping, or brown leaf edges. Upon noticing such indicators, adjust the watering routine accordingly to minimize water stress. Inspecting the moisture level of the soil, at about 1-2inches deep, can also help monitor the watering amounts. It should feel cool and slightly damp but not waterlogged.
