Spirea failing to thrive
I planted two Spirea's last April. Neither did particularly well. The worst one was replanted in the back garden and promptly died. So I was more patient with this one but it is not happy!
I've enriched the soil thinking it could be that - hardly any change. Kept an eye on moisture - helped a little but still looks withered and sad.
There are ants all over my garden - could these be the culprit?
Could anyone have a quick look and advise whether I should continue to have hope.
It is trying to flower but I'm wondering if I should cut it right down, would that help it to grow stronger?
