Wild hydrangea prefers consistently moist soil. Water deeply when the top 2-3 cm of soil feels dry, especially during hot, dry periods. Avoid waterlogging, as this can lead to root rot.

Regular watering promotes lush foliage and abundant blooms.

Prune wild hydrangea in late winter or early spring before new growth begins. It blooms on old wood, so prune lightly to remove dead, damaged, or crossing branches. For shaping, cut back stems to the desired height.

Heavy pruning can reduce flowering.

Wild hydrangea can be propagated by stem cuttings taken in early summer. Select healthy, non-flowering shoots, cut 10-15 cm lengths, and remove lower leaves.

Dip the cut end in rooting hormone and insert into a moist potting mix. Keep in a humid environment until rooted.

Repotting is generally not necessary for established wild hydrangeas in the ground.

Container-grown plants may require repotting every 2-3 years into a slightly larger pot, preferably in early spring before new growth starts. Ensure good drainage in the new container.
