Hydrangeas are a delightful addition to any garden, and if you’re in St. John’s, Newfoundland, you’re in for a treat. These beautiful flowering shrubs can thrive in the unique climate of St. John’s, but to make the most of them, you need to understand the various aspects of planting and caring for hydrangeas. In this comprehensive guide, we’ll delve deep into the world of hydrangeas in St. John’s and equip you with the knowledge to transform your garden into a hydrangea haven.
Hydrangea Varieties for St. John’s
Before diving into planting and care, let’s explore some hydrangea varieties that are well-suited to St. John’s’ conditions.
Bigleaf Hydrangeas (Hydrangea macrophylla)
Bigleaf hydrangeas are known for their iconic large, globe-shaped blooms that can change color depending on soil pH. For St. John’s, where the soil can be acidic due to the coastal environment, these hydrangeas are an excellent choice. They thrive in partial shade and require consistent moisture. Ensure you amend your soil if it’s not naturally acidic to achieve those stunning blue or pink blooms.
Smooth Hydrangeas (Hydrangea arborescens)
Smooth hydrangeas are hardy and well-suited to the climate of St. John’s. They produce large, round clusters of flowers in white or shades of pink. These hydrangeas thrive in full sun to part shade and are relatively low-maintenance. They can tolerate a range of soil types, making them a great choice for St. John’s gardens.
Panicle Hydrangeas (Hydrangea paniculata)
Panicle hydrangeas are gaining popularity for their elegant and cone-shaped flowers. They’re extremely hardy and can withstand colder temperatures, making them a reliable choice for St. John’s. These hydrangeas prefer full sun to partial shade and well-drained soil. With proper care, they can become the focal point of your garden.
Planting Hydrangeas
Now that you’ve chosen the right hydrangea variety, it’s time to get your plants in the ground. Proper planting is crucial for their long-term health and vigor.
Soil and Sunlight Requirements
Understanding the specific soil and sunlight preferences of your chosen hydrangea variety is key to success.
In St. John’s, where the soil can be naturally acidic due to the coastal environment, you might have the perfect conditions for bigleaf hydrangeas, known for their color-changing blooms. However, for smooth and panicle hydrangeas, it’s essential to ensure well-drained soil to prevent waterlogged roots.
When it comes to sunlight, most hydrangeas appreciate some shade, especially during the hottest part of the day. While they can tolerate full sun in cooler climates, partial shade is usually the best bet in St. John’s to prevent wilting and scorching.
Hydrangea Care Tips
Once your hydrangeas are in the ground, proper care is essential to ensure they thrive and reward you with abundant blooms.
Pruning and Deadheading
Pruning and deadheading are vital aspects of hydrangea care. The timing and technique can vary depending on the hydrangea variety you’ve chosen. For bigleaf hydrangeas, prune right after they finish flowering. Smooth and panicle hydrangeas can be pruned in late winter or early spring. Deadheading, or removing spent flowers, encourages new growth and more blooms.
Watering and Fertilizing
Hydrangeas in St. John’s benefit from consistent moisture but dislike waterlogged soil. Water deeply once a week during dry spells, and apply a balanced, slow-release fertilizer in the spring to promote healthy growth. Avoid excessive nitrogen, as it can lead to excessive foliage growth at the expense of flowers.
Dealing with Common Issues
Gardening often comes with challenges, and hydrangeas are no exception. Here’s how to address common problems they may encounter in St. John’s.
Pests and Diseases
Keep an eye out for common hydrangea pests like aphids and spider mites. Diseases like powdery mildew can also affect your plants. Regular inspection and early intervention with appropriate treatments can help keep your hydrangeas healthy.

St. John’s experiences cool temperatures, and frost can be a concern. To protect your hydrangeas, consider mulching the base of the plant to insulate the roots and covering them with frost cloth or burlap during harsh winter nights.
