What month do Annabelle hydrangeas bloom?
A heavy bloomer with mass appeal, ‘Annabelle’ Hydrangea illuminates the shade garden. Plants bloom for up to two months in June and July, with flower heads remaining attractive all summer and into the fall. As Paul explains, the ideal time to trim a hydrangea largely depends on its type, although autumn is never the right time to prune these ostentatious blooms. This is because most hydrangeas already have new flower buds on their stems. By cutting them back now, you would remove the buds and spoil next season’s blooms.Annabelle hydrangeas (Hydrangea arborescens) bloom on new wood, which means the flowers grow on stems that develop in the current season.

How do you prepare Annabelle hydrangeas for winter?
To protect Annabelle Hydrangeas during winter, it’s important to ensure proper care before the onset of cold weather. Similar to caring for other hydrangeas, mulching around the base with organic material such as leaves, straw, or wood chips can help insulate the roots from freezing temperatures. Ensure hydrangeas are properly prepared for winter by watering them before the ground freezes, applying mulch around their base for insulation, and covering delicate varieties with burlap or frost cloth during severe cold snaps. Monitor them occasionally for damage and maintain adequate moisture levels.If you find that your soil doesn’t need three fertilizations, you can just fertilize twice: in spring and early summer. For hydrangeas you overwintered in containers, give them fertilizer in early spring and again in May. There’s no need to fertilize again during summer.It’s best to start adding coffee grounds to the soil months before the blooming season begins, ideally in the late fall.

Established plants will shine with regular irrigation. Stop the watering schedule in September and let nature take its course.

When should you cut back Annabelle hydrangeas?

Next year’s flower buds won’t be formed until late spring the same year they bloom, so there is no risk of removing the buds if you prune in fall or spring.Hydrangeas are long-lived shrubs, sometimes living for up to 50 years if properly cared for. They enjoy morning sun but afternoon shade, and they need frequent watering during the growing season.If possible, overwinter hydrangeas outdoors, as they need to be exposed to the elements to stay in their natural rhythm.
