Nutrient Deficiencies
Hydrangeas are heavy feeders and require regular fertilization. Ensure your plants receive adequate amounts of nitrogen, phosphorus, and potassium. Use a balanced fertilizer specifically formulated for flowering shrubs.
5. Inadequate Watering
Hydrangeas prefer consistently moist soil, but they should not be overwatered. Deep watering is essential to encourage healthy root growth and prevent drought stress. Mulching around the base of your plants can help retain moisture and suppress weeds.
6. Pest and Disease Problems
Aphids, spider mites, and powdery mildew can damage hydrangeas and reduce flowering. Keep an eye out for signs of pests and diseases, and take appropriate action to control them.
By avoiding these common mistakes and providing your hydrangeas with the proper care, you can ensure that your plants continue to bloom beautifully year after year.
