In the spring, I was worried that I'd allowed my hydrangeas to become too parched in last year's long, dry summer. When I dead-headed them in March, they seemed very sad and were slow to form new flower buds - and the ones that did form were very small and scrawny.
I fed them some general fertiliser and hoped I hadn't actually killed them and fretted a bit because I really love them. I need not have worried. Two days ago, I returned from holiday to a fabulous display which I just had to share.
I've got another 'keen'... Ouch!
