Impatiens, commonly known as busy Lizzies, are a popular choice to add a vibrant touch to your garden or containers. Although they are generally easy to care for, it is not uncommon for their leaves to turn yellow, which can detract from their beauty. In this guide, we will explore the reasons behind impatiens leaves turning yellow and provide helpful tips to ensure their health and vibrancy throughout the summer months.
Understanding the Causes of Yellowing Impatiens Leaves
Normal Aging:
Not all cases of yellowing leaves are cause for concern. It is natural for older leaves to turn yellow and eventually fall off as they no longer contribute to the plant’s growth. This process may occur more quickly in leaves that are exposed to partial or full shade.
Pests and Diseases:
There are several pests and diseases that can cause the leaves of plants to turn yellow. One such pest is nematodes, which can cause yellowing leaves that improve as the day goes on. If your plants are infested with nematodes, it is important to remove and get rid of the affected plants. Another common culprit is a fungus called Botrytis blight, which can result in wilting flowers, weak stems, and yellowing leaves. To deal with this, it is recommended to trim and dispose of the infected parts, and then mist the plant with a solution of water and bleach. Downy mildew is another issue that can lead to brown spots and eventual yellowing of the leaves. To prevent its spread, it is necessary to remove both the infected plants and the contaminated soil. Lastly, there is a fungus called Verticillium wilt that can cause yellowing leaves, and it requires similar treatment as the other diseases mentioned.
Symptoms of insufficient nutrition or inadequate watering in plants can be observed through the yellowing of young leaves. To address this issue, it is recommended to provide the plants with essential nutrients by incorporating compost or slow-release fertilizer during the planting process. In the case of impatiens grown in containers, it may be necessary to fertilize them more frequently. Additionally, it is crucial to maintain the soil’s pH level within the range of 6.0 to 6.5, while ensuring it is enriched with humus and has proper drainage.
Maintaining a Proper Watering Routine:
Achieving the perfect watering routine is essential for the health of your plants. It is important to find the ideal balance, as both excessive watering and not watering enough can result in the dreaded yellowing leaves. Overwatering presents a challenge as it saturates the roots, making it difficult for them to absorb the necessary nutrients. On the other hand, underwatering leads to dehydration and stresses the plant. To strike the right balance, you can use a simple trick – just stick your finger into the soil to assess its moisture level. If the top inch feels dry, it’s a clear indication that your plants are in need of hydration.
Useful Tips for Keeping Your Impatiens Healthy
Getting Started:
When planting your impatiens, make sure to incorporate compost or slow-release fertilizer into the soil. This will provide them with the essential nutrients they need to thrive. If you are planting them in containers, adjust your fertilization schedule accordingly.
Keeping Pests and Diseases at Bay:
Regularly inspect your impatiens for any signs of pests or diseases. If you do find any, it’s important to take immediate action by removing and discarding affected plants and plant parts. To prevent the buildup of diseases, consider rotating the locations where you plant your impatiens.
Finding the Right Balance of Water:
It’s crucial to water your impatiens appropriately. The soil should be moist, but not waterlogged. To check the moisture level, simply stick your finger into the soil. If the top inch is dry, it’s time to water your impatiens.
Finding the Perfect Amount of Sunlight:
Impatiens thrive in areas with partial to full shade. To ensure their health and prevent leaf yellowing, make sure they are receiving the right amount of sunlight.
Creating Ideal Soil Conditions:
For optimal growth, it’s important to maintain slightly acidic soil with a pH level between 6.0 to 6.5. Additionally, the soil should be well-drained and rich in humus.
By following these practical tips, you can ensure that your impatiens remain healthy and vibrant throughout their growing season.
