Furthermore, what causes purple spots on hydrangea leaves?Leaf spots on hydrangeas caused by bacteria are from the pathogen Xanthomonas campestris. Similar to cercospora, this will typically start at the base of the plant on the lower leaves, and will be either purple or red in color. The spots by the veins will become angular.Beside above, what nutrient deficiency causes purple leaves? Nitrogen (N) Plants are short; leaves tend to be pale green-yellow in color, especially on the older foliage. On tomato plants, the undersides of the leaves and stems can develop a purple coloration. Phosphorus (P) Plants are usually stunted and a dark green color. Considering this, how do I turn my hydrangeas purple? Generally speaking, acidic soil, with a pH lower than 6.0, yields blue or lavender-blue hydrangea blooms. Alkaline soil, with a pH above 7.0, promotes pinks and reds. With a pH between 6 and 7, the blooms turn purple or bluish-pink. To lower your pH, add garden sulfur or aluminum sulfate to your soil.Why are the leaves on my hydrangea turning black?Hydrangeas love water, but excessive irrigation or wet foliage injures plants. Insufficient water causes leaves to turn black or brown. Severe drought conditions cause entire plants to defoliate. Too much water at the root zone, combined with a poorly draining site, causes root rot that promotes black spots on leaves.
