How to Care for Endless Summer Hydrangea

Overview

Endless Summer hydrangeas differ from other hydrangeas in that they bloom on both old and new wood. This makes for a much longer flowering period, extending the blooming cycle by up to 12 weeks in some cases. Endless Summer hydrangeas are ideal for gardens in cool climates, as it is not necessary to wait for new growth to appear before blooms can be enjoyed. This plant is hardy in USDA Zones 4 and above and does not require excessive attention or special care in order to thrive.

Step 1

Dig a hole that is twice the diameter and the same depth as the container the Endless Summer hydrangea was purchased in. Plant the flower with the root ball at the same level it was growing in the container. Pat the soil down firmly to remove air pockets.

Step 2

Add enough water at the time of planting to thoroughly saturate the soil. Add a 2-inch layer of organic mulch to seal in moisture, protect the roots from harsh weather and prevent weed growth.

Step 3

Water two to three times each week, soaking the plant well at each watering.

Step 4

Fertilize with a slow-release 10-40-10 fertilizer in early spring or summer. Stop fertilizing altogether around mid-August in cool regions and during early September in other areas.

Step 5

Remove faded flowers during the growing season. In late summer or early fall the blooms can be left in place to add interest to your garden and help protect the stems from cold weather. The faded blooms should be removed in early spring.

Step 6

Add a 4-inch layer of organic mulch in late fall, before the first hard freeze. Remove the covering in the spring, after all danger of frost has passed for your region.
