How Much Water to Use      

Water thoroughly each time — enough that it flows out the pot's drainage holes. A light splash on top of the soil only wets the surface and encourages roots to stay shallow. After watering, let the pot drain completely and never let it sit in standing water. 

How Often to Water      

There's no universal schedule, because it depends on the plant, the pot, the season, and the light it's getting. A plant in bright light and a terracotta pot will dry out faster than the same plant in low light and a plastic pot. Check the soil before watering rather than watering on autopilot, and expect to water less often in fall and winter.  

Top Watering vs. Bottom Watering       

Top watering — pouring water evenly over the soil surface — works for most plants. Bottom watering, where the pot sits in a tray of water until the soil wicks up moisture from below, is useful for plants prone to crown or stem rot, like African violets, since it keeps the top of the soil and the base of the plant dry.  

Water Quality Matters      

Use room-temperature water; cold water can shock roots. Some sensitive plants, like spider plants or peace lilies, are prone to brown leaf tips from the chlorine, fluoride, or salts in tap water — letting tap water sit out overnight, or using filtered or rainwater, can help. 

Common Watering Mistakes      

• Watering on a fixed schedule instead of checking the soil first. 

• Letting the pot sit in a saucer full of water after watering. 

• Shallow, surface-only watering that never reaches the roots. 

• Using ice cubes as a "slow watering" method — the cold can stress roots. 

• Misting as a substitute for actual watering; misting raises humidity, not soil moisture.
