If you have a hydrangea that refuses to bloom then you should watch this video. Roger Cook from This Old House explains why there is a problem with this particular plant and then suggests various alternatives. The final choice is a Hydrangea Macrophylla which has pink flowers, but by adding aluminum sulphate to the soil next years blooms will be blue. Watch the video below which also includes a full demonstration of the best planting method.
Beautiful!
This is my problem for 3 hydrangeas, 2 pink and 1 blue now to replace them will be a expensive venture
