Plant Care Tips

Watering

Maintain consistent moisture, especially in the first year after planting; water deeply once a week, more frequently during hot, dry spells.

Fertilizing

Apply a slow-release fertilizer formulated for hydrangeas in early spring to support growth and blooming throughout the season.

Pruning

Prune in late winter or early spring, removing only dead wood and spent flowers to encourage reblooming on new growth.

By Season

Spring Care

Mulch to retain moisture and control weeds, apply fertilizer, and prune as needed to remove any dead branches.

Summer Care

Continue to provide water during dry periods and apply a second round of fertilizer in mid-summer to support continued blooming.

Fall Care

Reduce watering as the plant prepares for dormancy and apply a protective layer of mulch to insulate the roots against freezing temperatures.

Little care is needed in winter; however, in colder zones, ensure adequate mulch is in place to protect the plant.
