To protect your hydrangeas from pests and diseases, consider the following expert tips:
Regularly inspect your hydrangeas for signs of pests such as aphids, slugs, and scale. Look for yellowing leaves, holes, or sticky residue, which can indicate infestations.
Water your hydrangeas at the base using a soaker hose or drip irrigation to keep the leaves dry. This helps prevent fungal diseases like powdery mildew and leaf spots, which thrive in humid conditions.
Clean up fallen leaves and debris around your hydrangeas, as these can harbor pests and diseases. Dispose of any infected plant material properly to prevent the spread of pathogens.
Use organic pest control methods, such as neem oil or insecticidal soap, to treat infestations. For slugs, consider placing traps or using crushed eggshells around the base to deter them.
Ensure your hydrangeas are well-fed and hydrated. Healthy plants are more resilient to pests and diseases. Use a balanced fertilizer and maintain consistent watering, especially during dry spells.
By implementing these strategies, you can effectively protect your hydrangeas and promote their health and beauty.
