Hydrangea plus ? Compost

Delia O\’Sullivan asked 12 years ago

I bought two White Hydrangea last July. I transplanted both into larger containers earlier this year using John Innes Multi Purpose compost. Now the flowers are becoming reddish around the edges & the leaves also. Should I use John Innes Ericaceous compost? If yes, do I remove all the old compost from around the root ball? I would like to keep the Hydrangeas in containers for another while.

White hydrangea will tend to turn pink in limy soil and with limy water used, and the leaves will turn reddish if water watering was not adequate.

Use rainwater if possible and an acid-lover’s plant food.
