Impatiens (Impatiens walleriana) is an annual flowering plant, native to Africa. Impatiens is, according to horticulturists with the Iowa State University Extension, the most widely grown bedding plant in the U.S. An easy to grow plant, it does well planted in bunches in beds or in hanging baskets. Plant the impatiens outdoors after all danger of frost has passed.
Harden off nursery-purchased impatiens by placing them in a shady, protected area of the garden. Gradually give the impatiens more filtered sunlight every day for five days.
Find a place to plant the impatiens. Look for an area that receives dappled shade, where the soil is well-drained.
Amend the soil with 3 inches of compost, mixed into the top 6 inches of soil.
Dig holes for the impatiens that are the same depth as the nursery pots and twice the diameter. Remove the plants from their containers and place the roots into the holes. Fill the hole with soil and use your hands to pat lightly around the base of the plant.
Water the impatiens until the top 4 inches of soil is moist, and water weekly if there is no rain. Be careful not to overwater the plants. Stick your finger into the soil to determine when it is time to water. If the top inch of soil is dry, water the impatiens. If you are growing the impatiens in containers, the soil will dry faster, so check periodically and water when the top of the soil is dry to the touch.
Fertilize bed-planted impatiens with an all-purpose fertilizer in the spring. Container-grown plants need to be fertilized every two weeks with a water-soluble, all-purpose fertilizer. Always water before and after fertilizing.
