How to Water Impatiens

Spread a 2- to 4-inch layer of compost over the planting bed before transplanting the impatiens in spring, or around the plants if already in place. Work the compost into the top 6 inches of soil. Compost aids drainage in heavy soils so it doesn't become soggy, and prevents sandy soils from drying out too quickly.

Water potted impatiens when the top inch of soil begins to feel dry, usually once a day. Irrigate from the top of the pots until the excess water drains from the bottom, then empty the drip tray so the impatiens do not sit in the standing water.

Water bedded impatiens once weekly, moistening the top 6 inches of soil at each irrigation. Check the soil moisture often during hot dry weather and water more often if the soil begins drying. Impatiens may require daily watering during the height of summer, advises the Alabama Cooperative Extension.
