When to Plant Hydrangeas in Colorado

Introduction

Hydrangeas are beautiful flowering plants that add beauty and charm to any garden. However, planting them at the right time is crucial to ensure they thrive and flourish. If you are a gardener in Colorado and want to know when to plant hydrangeas, then you have come to the right place.

The Best Time to Plant Hydrangeas

In Colorado, the best time to plant hydrangeas is in the spring or fall. Spring is considered the ideal season to plant hydrangeas since the soil is warm and the air temperature is cool. This allows the plant to establish roots before the hot summer months. Fall is another option since the weather is cooler, and the soil is still warm from the summer months.

Preparing the Soil

Hydrangeas prefer well-drained, moist soil that is rich in organic matter, so it is important to prepare the soil before planting. Start by loosening the soil to a depth of 12 inches and adding compost or organic matter to increase fertility and promote drainage. If your soil is too clayey, mix in sand or perlite to improve drainage.

Planting Hydrangeas in Containers

If you plan to grow hydrangeas in containers, the best time to plant them is in the spring or a mild fall. Select a container that is at least 18 inches wide and has drainage holes. Fill the container with a well-draining soil mix, such as equal parts peat moss, perlite, and vermiculite. Place the hydrangea into the container, making sure it is level with the soil surface. Water deeply to ensure the roots are well-established.

Caring for Hydrangeas

Hydrangeas need regular watering to thrive, especially during the hot summer months. Water deeply once a week, making sure the soil is moist but not waterlogged. Fertilize the plants in the spring and late summer with a balanced fertilizer to promote healthy growth and flowering. Deadhead spent blooms to encourage the plant to produce more flowers. In the fall, cut back the stems to about 12 inches from the ground to prepare the plant for dormancy.
