Hydrangea Cultivation
A staple in gardens across the world, hydrangeas are popular because they are easy to cultivate, tolerate almost any type of soil, and produce abundant blooms. However, there is a right and wrong way to grow them. Read on for the tips and tricks of cultivating a brilliant hydrangea shrub. But first…
A Brief History of Hydrangeas
Although prevalent worldwide, hydrangeas initially grew in Japan. Legend has it that an Emperor became the first person to cut its blooms and gift them to a woman he had angered – he loved her deeply but had callously neglected her in favor of his work. From that moment, the Japanese began associating hydrangea flowers with gratitude and apology, but as the centuries went on, the meaning morphed depending on the color. Pink hydrangeas conveyed romance and harmony. White, purity and grace. Purple, friendship and leadership.
As world commerce increased during the renaissance, hydrangeas spread first to Eastern Europe – where it took on the Greek name combining water (hydros) with jar (angos) – and later Western Europe by way of the new world – where it had already been growing for centuries.
In Europe, the flowers took on a completely different connotation. Because hydrangeas produce a lot of flowers but very few seeds, Europeans began associating the plants with arrogance or boastfulness. In fact, English men in the 1800s used to send hydrangeas to women who rejected them.
How to care for Hydrangeas
Ensuring your hydrangeas thrive and become the pride of your garden requires a combination of knowledge and attentive care. Hydrangeas are resilient and adaptable, but they flourish best when provided with the right conditions and care routines. From selecting the optimal location to adjusting soil conditions, there are several key practices to keep in mind.
The following tips will guide you through the essential steps to cultivate vibrant and healthy hydrangea shrubs that will enhance the beauty of your garden.
Where to plant hydrangeas
Hydrangeas thrive in locations that receive morning sun and afternoon shade. Avoid planting them in full sun or full shade. Too much sun can scorch the leaves, while too much shade can reduce blooming. Find a balance with morning sun and afternoon shade.
What soil to use when planting hydrangeas
While hydrangeas tolerate various soils, they prefer well-drained, moist, and slightly acidic soil. Adding compost can enhance soil quality and promote healthy growth. Make sure your soil PH levels are balanced. The color of bigleaf hydrangea flowers depends on soil pH. Test your soil and amend it to achieve the desired bloom color.
Add mulch: Mulch around the base of the plants help to retain soil moisture and regulate temperature, lack of mulch can stress your plants and affect blooming. Organic mulches like pine bark or straw work best.
Adjusting Bloom Color: You can change the color of bigleaf hydrangeas by altering the soil pH. For blue flowers, make the soil more acidic by adding sulfur or peat moss. For pink flowers, increase alkalinity with lime.
How to water hydrangeas
Hydrangeas need consistent moisture, especially during the growing season. Water them deeply once a week, more frequently during dry periods. Avoid overhead watering to prevent fungal diseases.
Avoid overwatering: Hydrangeas need consistent moisture. Over-watering can lead to root rot, while under-watering causes wilting. Ensure the soil is well-drained and water deeply.
Fertilizing: Apply a balanced, slow-release fertilizer in spring and again in summer. Avoid over-fertilizing, which can lead to lush foliage but fewer blooms.
How to prune hydrangeas
Pruning depends on the type of hydrangea bush. For example, bigleaf hydrangeas bloom on old wood, so prune them after flowering. Panicles and smooth hydrangeas bloom on new wood and can be pruned in late winter or early spring.
Avoid over-pruning: Incorrect pruning can reduce blooming. Know your hydrangea type and prune accordingly. For instance, avoid cutting back bigleaf hydrangeas in spring as they bloom on old wood.
Common Mistakes When Planting Hydrangeas
Despite their hardiness, gardeners can make mistakes when caring for hydrangeas. Recognizing and avoiding these common errors will help ensure your hydrangeas remain healthy and vibrant.
Overwatering: Over-watering can lead to root rot. Ensure the soil is well-drained after watering.
Lack of mulch: Lack of mulch can stress your plants and affect blooming.
Over-fertilizing: Too much fertilizer can result in lush foliage but fewer blooms.
Over-pruning: Excessive trimming of hydrangea bushes can reduce blooming.
