Hydrangeas are medium-sized bushes with green leaves and large pom-pom-shaped flower blossoms. Although blue, pink and purple hydrangeas are a common sight in many gardens, there are also hydrangea bushes with cream-coloured blooms. These varieties include Hydrangea arborescens Annabelle, Hydrangea quercifolia, oakleaf hydrangea, Hydrangea anomala petiolaris and climbing hydrangea. The growing needs for cream-coloured hydrangeas are identical to those for other hydrangea bush colours.
Wait until early spring when the threat of frost has passed and choose an outdoor location that receives full morning sun and afternoon shade.
Dig a hole that is approximately 1 foot deep and 2 feet wide using a shovel. Remove the cream-coloured hydrangea from the pot and insert the roots into the hole. Make sure that the top of the roots are even with the top of the hole and fill the hole with soil.
Spread a 10-10-10 slow-release, granular fertiliser over the soil under the hydrangea bush using the amounts specified on the fertiliser package for a single plant. After the initial planting, fertilise once per year in the spring with the same fertiliser.
Water the soil under the hydrangea well until it is completely saturated. After planting, water the soil to keep it constantly moist but not soggy. If rainfall occurs, additional watering is not required.
Spread a 2- to 3-inch layer of mulch around the base of the hydrangea plant to prevent water from evaporating from the soil.
Prune the hydrangeas in the late summer as soon as the flowers start to wilt. Cut each stem back to the desired height using hand pruners. You should also prune out any brown or yellow stems near the base of the plant.
If you plant the Anomala petiolaris hydrangea, insert a trellis behind it to support its vining growth.
