Hydrangea seemanii - 2014

Hi Andrew,

this is a beautiful specimen. How do you tend for it? For some reason mine is suffering from blackening around the edge of the leaves. Any advice would be most appreciated.

Andrew - I ignore it! To be honest, it doesn't get any attention apart from reducing to stop it climbing a telegraph pole. As it is not the hardiest of plants, it may have frost damage. The dark leaf margins could also be caused by magnesium deficiency - spraying them with Epsom salts should rectify this.
