I've agreed to take a rather sad looking Hydrangea from my mum's garden to see if I can revive it. I'll keep it in my garden if I can so it doesn't need to return. However, my Mum has confessed to putting ericaceous compost in the container. I already have 2 healthy hydrangeas growing happily in my garden so I can only assume our soil is fine for hydrangeas.
The plant does have new growth on it but not very much compared to mine. It's standing about 18-24" high. But what do I do? I guess I need to give the roots a gentle shake before planting to get rid of the ericaceous compost and add bone meal when I replant it. But, will I prune it right down and hope that it will like it's new home and grow happily or will I leave it well alone? All and any advice gratefully received.
