B-9 is effective at controlling height and darkening foliage color, may be required on Berlin. Prune or pinching soon after potting will produce a finished product that doesn't open up when it flowers. The key is to make the first prune at the level of the first set of leaves closest to the soil.

Grower Tips: 

It's the pink 'Annabelle' hydrangea! Invincibelle Spirit is as hardy and adaptable as 'Annabelle' but produces loads of hot pink flowers from early summer to frost. It's a reliable bloomer in the north and is also heat tolerant.

May be pruned back in late winter to encourage strong new growth and blooming. Adaptable to most moist, well drained soils. Bloom color is not affected by soil pH.

Do not move outside
Vernalization: 
Cold Required
