Impatiens are a shade-tolerant, flowering annual that blooms continuously through the summer months. They do well under trees and on the north sides of buildings where there is too little sun for most other flowering plants. They come in a variety of flower colors, including pink, orange and violet. Planting out newly purchased bedding plants to the garden must be done properly to guard against shock to the plants, and proper care as the impatiens become established in the bed helps ensure they thrive all season long.
Work a slow-release, balanced fertilizer into the soil at planting or right after planting, following the application amount recommended on the package. Work the fertilizer into the soil 3 to 5 inches away from the impatiens' stem if you are fertilizing after planting, as fertilizer that comes in direct contact with the plants can burn them.
Water newly planted impatiens thoroughly immediately after planting, irrigating until the soil feels moist to a 6-inch depth. Continue to water as needed throughout the summer so that the soil remains moist but doesn't become soggy.
Water impatiens at the base of the plants to prevent water from splashing onto the leaves. Wet foliage combined with the low-sunlight conditions impatiens prefer make them susceptible to fungus.
Lay a 2-inch layer of organic mulch, such as bark, around the impatiens plants. Mulch preserves soil moisture, keeps the plant's roots cool and prevents weed growth in the bed.
Check impatiens for insect pests, primarily aphids, throughout the growing season and particularly right after planting. Newly planted impatiens are more susceptible to insects than established plants. Check the undersides of the leaves for damage or signs of the insects and treat with insecticidal soap, following package application instructions, if an infestation is discovered.
