New Guinea impatiens flowers are a common bedding plant, as well as a dependable container flower. Gardeners enjoy adding New Guinea impatiens plants to shady areas of a home landscape. This variety of impatiens is relatively easy to maintain and does not need excessive care to keep it looking healthy and attractive. Water your New Guinea impatiens flowers regularly to prevent the plants from wilting and showing symptoms of stress from lack of water.
Monitor the amount of rain that falls during each week, especially when you have the New Guinea impatiens plants planted directly into the soil. If less than 1 inch of rain falls within a one-week period, provide additional water.
Provide water for your New Guinea impatiens flowers growing in the soil once per week if less than 1 inch of rain falls. Water the soil around the flowers instead of the foliage. Allow the hose to run for at least five minutes over the entire growing area to provide deep watering. Deep watering will strengthen the root systems and help the New Guinea impatiens flowers grow deeper into the soil.
Give water to New Guinea impatiens flowers growing in containers to keep them evenly moist. Provide water to moisten the soil, but not so much that you saturate the soil with standing water. Allow the soil to dry to the point of dampness between watering and then water again.
Add approximately 2 inches of mulch to the soil around New Guinea impatiens (both growing in the soil and in containers). The mulch will help conserve moisture in the soil and will facilitate faster growth.
