Impatiens walleriana, commonly known as Busy Lizzie, is a popular flowering plant known for its bright, colorful blooms that come in shades of pink, red, white, purple, and even bicolor combinations. With its ability to thrive in shady areas, this plant is a favorite among gardeners looking to brighten up low-light spots. Impatiens are relatively easy to grow and maintain, making them a great choice for both beginners and seasoned gardeners alike. Whether you're growing them in containers, hanging baskets, or flower beds, here’s your complete guide to caring for Impatiens walleriana.
Impatiens walleriana thrives in partial to full shade. While they can tolerate some direct sunlight, too much can scorch their leaves and cause the flowers to wilt prematurely. Ideally, Impatiens should be grown in locations where they will receive indirect light or filtered sunlight, making them perfect for spots under trees or along the shaded sides of buildings.
If growing Impatiens indoors, place them in a spot where they can get bright, indirect light, such as near a window that doesn’t receive harsh direct sunlight. Too much sun indoors can cause the leaves to yellow and the flowers to wilt.
Impatiens are water-loving plants that require consistent moisture to thrive. They prefer evenly moist, well-drained soil but can suffer from root rot if overwatered or if the soil doesn’t drain properly. Water your Impatiens when the top inch of soil feels dry to the touch. Ensure that the plant is watered deeply, allowing the water to reach the roots, but avoid allowing the plant to sit in standing water.
During the hot summer months, Impatiens may need more frequent watering, especially if they’re in containers. If grown outdoors, you may need to water them daily if the weather is particularly dry or if the plants are in containers with limited soil space. Indoors, water them thoroughly when the soil begins to dry out. Always check that the pot has proper drainage to prevent water from collecting at the bottom.
Impatiens walleriana prefers moderate temperatures and does best in a range of 60°F to 75°F (15°C to 24°C). These plants are not frost-tolerant and will suffer damage if exposed to temperatures below 50°F (10°C). In colder climates, Impatiens are typically grown as annuals, but in warmer climates, they can be perennial plants that bloom year-round.
When growing Impatiens indoors, make sure they are kept away from drafts, air conditioners, or heaters, as temperature fluctuations can stress the plant. Impatiens are also quite sensitive to low humidity, and the dry air in many homes, especially during the winter months, can affect their growth. To maintain adequate humidity, you can place a humidity tray under the plant, or mist the leaves occasionally with water, making sure not to wet the flowers.
To keep your Impatiens thriving and blooming, regular fertilization is essential. Impatiens are relatively heavy feeders and benefit from a balanced liquid fertilizer or a slow-release granular fertilizer. Apply a balanced, water-soluble fertilizer every 2-4 weeks during the growing season (spring through summer) to encourage healthy growth and vibrant flowers.
If you’re growing Impatiens in containers, you may need to fertilize more frequently, as container soil tends to lose nutrients more quickly than garden soil. Be careful not to over-fertilize, as this can result in more leaves and less flowering. During the fall and winter months, when the plant’s growth slows down, reduce or stop fertilizing altogether.
Impatiens do not require much pruning, but regular maintenance can help keep them looking their best and encourage continuous blooming. Deadheading (removing spent flowers) is essential to prevent the plant from putting energy into seed production, allowing it to focus on producing more flowers.
If your Impatiens starts to look leggy or sparse, you can also pinch back the growing tips to encourage a bushier shape. If the plant is in a hanging basket or container, it may benefit from occasional light pruning to keep it tidy. Pruning should ideally be done during the growing season, while the plant is actively flowering.
For plants grown in containers, it’s a good idea to replace the soil every year, as nutrients in the soil can be depleted, and the soil can become compacted. When doing so, be sure to use fresh, well-draining potting mix to ensure proper drainage.
Propagating Impatiens walleriana is possible through cuttings. Here’s how to propagate your Impatiens:
Propagation is a great way to expand your Impatiens collection or share plants with friends and family.
Good news! Impatiens walleriana is non-toxic to pets, so you don’t need to worry about your cats or dogs nibbling on the plant. However, while the plant itself isn’t toxic, it’s still best to discourage pets from chewing on the leaves or flowers, as ingesting large quantities of any plant matter can cause mild digestive upset.
If you have pets, place your Impatiens in an area where they are less likely to be disturbed or kept out of reach.
Q: Why are the leaves of my Impatiens turning yellow?
A: Yellowing leaves on Impatiens can be a sign of overwatering, poor drainage, or nutrient deficiency. Make sure the plant is not sitting in water and that the soil is well-draining. If the plant is in a container, check that the pot has proper drainage holes.
Q: How can I get my Impatiens to bloom more?
A: To encourage more blooming, make sure the plant is getting enough indirect sunlight, consistent moisture, and regular feeding. Deadhead spent flowers regularly, and prune the plant to maintain its shape. Also, ensure that the plant is not stressed by environmental factors like pests or temperature fluctuations.
Q: Can I grow Impatiens indoors?
A: Yes, Impatiens can be grown indoors, especially in bright, indirect light. Keep them away from direct sunlight, which can scorch the leaves, and ensure that they have sufficient humidity and warmth. Impatiens are an excellent choice for filling low-light indoor spaces with vibrant color.
Q: How do I prevent my Impatiens from getting leggy?
A: To prevent legginess, make sure your Impatiens receives enough indirect sunlight. Pinch back the growing tips regularly to encourage bushier growth, and make sure the plant is receiving consistent moisture and nutrients.
Q: How often should I water my Impatiens?
A: Water your Impatiens when the top inch of soil feels dry to the touch. Make sure the plant is watered thoroughly but avoid letting it sit in water, as this can cause root rot. During hot weather or if the plant is in a container, you may need to water more frequently.
