Lacecap Hydrangea has some crispy leaves
Does anyone have any advice as to what is causing my lacecap hydrangea's leaves to start going a bit crispy? There is no browning of the leaves, they just look and feel a bit desiccated. No obvious signs of pest infestation. I have been putting colourant on them to ensure they go blue, but I have also done this with the mopheads to the same degree and they're showing no signs.
