I just purchased a Blue endless summer. Do I add anything to the soil now to keep it blue? And how often?

The color of Hydrangea Endless Summer is soil dependent. If you want blue flowers; add a couple of handfuls of aluminum sulphate at planting. If you want pink flowers; use lime. You will probably have to refresh the treatment with a single handful of the desired product each summer to keep the soil conditioned.
