Q.Hydrangea Seemannii – Infestation

Zone St Albans | ANGE added on May 5, 2020 | Answered

My plant has some sort of infestation which I can’t pinpoint – some leaves have holes in them, others look dried out. Could you please advise what this could be and what I could do about it? Many thanks in advance 🙂
