Hanging baskets are a great way to garden in small, restricted spaces like balconies or porches. But plants grown in hanging baskets have different needs than plants grown in the ground. One of the most significant differences is that plants in hanging pots dry out more quickly. To prevent your hanging plants from becoming drought stressed, you must monitor their moisture levels and water them more frequently than your in-ground garden plants.
Check your hanging pot's moisture level twice daily until you get a feel for how often it needs to be watered during each season. Stick your finger into the soil a few inches deep. If your hanging pot has average water needs, it will need to be watered when the top third of the pot's soil dries out.
Water your hanging pot with a watering can whenever the soil is dry. Water it with enough water so that water drips out of the drainage holes in the bottom of the pot.
Take your hanging pot down and submerge the bottom few inches of the pot in water if the soil completely dries out. Take the pot out of the water when the top of the soil feels moist.
