Q: I have a hydrangea growing in a large pot my patio. I bought it from a lady who was moving and she had it for several years. It was doing well through the summer but now there are white spots on the leaves. I live in southern California. The soil seems damp. Am I watering too much? Also, the flowers are not turning a true pink color anymore. A: During the dormant season, spots are common. Clean all old leaves away from the plant. To achieve a pink color, add agricultural lime to soil. It takes about a year to raise pH for pink flowers. |
