How to Plant and Care for Hydrangeas
Hydrangeas are a timeless garden favourite, loved for their large, show-stopping blooms and ability to bring colour and elegance to any outdoor space. Whether you’re planting one in a border or styling it in a container, getting the basics right will ensure your hydrangea thrives and rewards you with beautiful flowers year after year. In this guide, we’ll walk you through everything you need to know—from planting and positioning to care tips and even how to influence their colour.
Planting Your Hydrangea
Give your hydrangea the best start by enriching the soil with plenty of well-rotted compost or manure. This helps retain moisture—something hydrangeas love—while still allowing for good drainage. Keep plants well watered, especially during the first few weeks after planting, as they establish.
Choosing the Right Spot
Hydrangeas thrive in moist, well-drained soil in a cool, partially shaded position. Shelter from strong winds is important, as young spring growth can be damaged. While they prefer some shade, they can tolerate sunnier spots as long as the soil doesn’t dry out.
Growing in Pots & Containers
Hydrangeas also perform beautifully in pots and tubs. During the summer months, they’ll need regular watering—often daily in warm weather—and benefit from a weekly liquid feed throughout spring and summer. If you’re growing blue varieties in containers, use hydrangea colourant to maintain their rich blue tones, as this depends on acidic soil conditions.
Understanding Flower Colour
One of the most fascinating features of hydrangeas is their ability to change colour depending on soil pH. Blue and pink varieties will appear blue in acidic soil, mauve in neutral conditions, and pink in more alkaline soils. White and green varieties remain unchanged. For the best chance of keeping blue flowers vibrant, use rainwater where possible, as mains water can gradually alter the soil balance.
