I have several Hydrangeas that I thought were healthy but they have these ugly spots on them with some leafs have died. Any idea what this is and how to deal with it?
Hydrangea problem?
Your ugly spots may be what is called "leaf spot" (cercospora hydrangeae). The identifiers for this fungus are, brown to yellow spots or blotches on the leaf surface. The spots may have dark or yellowish margins, and the leaves may shrivel and drop prematurely. Does this sound like what you have?
The fungus is spread by the air, or splashing water, and it's favored by prolonged cool, wet, conditions. It harbors in the spent plant debris. Good horticultural practices during the growing season will help to control this fungus. You should avoid wetting the foliage at all cost. Use a drip irrigation if possible, or keep the main stream of water directed towards the base of the plant when irrigating with the garden hose. Do not splash soil from around the root zone. Use good sanitation practices and remove and dispose of debris and infected leaves. Make sure there is no buildup of fallen leaves around the base of the plant, this is where the fungus thrives. Like one poster said, it is getting late in the season and the foliage will be dropping for the winter months, so about all you can do at this late stage in time is remove the fallen leaves immediately when they drop. It's rather late to apply a fungicide at this time. Hope this answers your question.
