Impatiens Growing Guide
Crop Rotation Group
Fertile, well-drained soil.
None. Impatiens cannot tolerate cold temperatures.
Mix a standard application of a balanced organic fertiliser into the soil prior to planting. In midsummer, drench plants with a liquid plant food to stimulate new growth.
Impatiens grow better in shade than most other annuals. You can combine them with coleus with leaf colours that echo those from impatiens blossoms.
Single Plants: 20cm (7") each way (minimum)
Rows: 20cm (7") with 30cm (11") row gap (minimum)
Sow and Plant
Sow impatiens seeds indoors in moist seed starting mix, and provide very bright light. Most gardeners buy impatiens seedlings, which are widely available as bedding plants. Allow 30cm(12 inches) between taller varieties of New Guinea impatiens.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.
Impatiens need a steady supply of water. Varieties are available in more than twenty different colours and bicolours.
Impatiens shed their old blossoms cleanly, so there is little need for removing old blossoms. However, pruning back tired plants in late summer can help stimulate new growth.
Spider mites can be a problem, especially with impatiens grown in containers. In recent years, impatiens downy mildew has become a serious problem following periods of cool rain.
