New Guinea impatiens are beloved for their vibrant flowers and lush foliage, but they are sensitive to cold weather. In regions with frost, these tender perennials need special care to survive the winter. Here’s how to overwinter New Guinea impatiens so you can enjoy them again next season.
Step 1: Assess Your Plants
- Healthy Plants: Choose healthy, disease-free plants for overwintering. If your New Guinea impatiens are still blooming or have healthy foliage, they’re good candidates for winter care.
Step 2: Move Indoors Before Frost
- Timing: Before the first frost hits, bring your New Guinea impatiens indoors. Frost can damage or kill them, so early action is key.
- Potting: If they are planted in the ground, gently dig up the plants, taking care not to damage the roots. Replant them in pots with well-draining soil.
Step 3: Provide Proper Indoor Care
- Light: Place the potted plants in a location with bright, indirect light. A south-facing window or a spot with plenty of natural light is ideal.
- Temperature: Keep the indoor temperature between 60-70°F (15-21°C). Avoid placing the plants near drafts or heat sources.
- Watering: Water the plants sparingly. Allow the top inch of soil to dry out between waterings to prevent root rot. Reduce watering during the winter months when the plant’s growth slows down.
Step 4: Monitor and Maintain
- Pruning: Trim back any leggy growth or spent flowers to encourage compact growth. Removing dead or yellowing leaves will help keep the plant healthy.
- Pest Control: Keep an eye out for pests like aphids or spider mites. If you notice any, treat the plants with insecticidal soap or neem oil.
Step 5: Transition Back Outdoors in Spring
- Acclimation: Once the danger of frost has passed and temperatures are consistently above 50°F (10°C), gradually reintroduce your New Guinea impatiens to outdoor conditions. Start by placing them outside for a few hours each day, increasing their time outdoors over a week or two.
- Replanting: If you plan to return them to the garden, transplant them back into the ground once they’ve acclimated.
Conclusion:
Overwintering New Guinea impatiens is a simple way to save your plants from season to season. By following these steps, you can protect your impatiens from the cold and enjoy their vibrant blooms year after year.
