Ornamentals: Grow Hydrangeas in Containers

Growing ornamentals like hydrangeas in containers is easy if you know their specific needs. As an experienced horticulturist, I’ll guide you through the essential steps to cultivate thriving hydrangeas in containers, transforming your outdoor spaces into vibrant oases.

Choosing the Right Container:

Hydrangeas require a container with ample space for their roots to spread. A pot at least 24 inches wide with drainage holes is ideal. Terracotta or plastic containers are both suitable options.

Creating the Perfect Growing Environment:

Hydrangeas thrive in well-draining soil. Use a potting mix designed for container gardening and amend it with compost or peat moss to improve drainage and fertility. Position your container in a location that receives at least six hours of sunlight daily but protect it from afternoon heat.

Cultivating Compact Varieties:

Consider choosing compact hydrangea cultivars that are well-suited for container cultivation. Some popular varieties include ‘Endless Summer’, ‘Blushing Bride’, and ‘Penny Mac’.

Essential Care Tips:

• Watering: Water your hydrangeas regularly, especially during hot weather. Allow the top inch of soil to dry out before watering again. Overwatering can lead to root rot.
• Fertilizing: Fertilize your hydrangeas monthly with a balanced fertilizer during the growing season.
• Pruning: Prune your hydrangeas in late winter or early spring to remove dead or damaged stems and encourage new growth.
