Guide to Growing Bigleaf Hydrangea Plant in a Pot

Bigleaf hydrangeas, also known as Hydrangea macrophylla, are a popular choice for gardeners due to their large, showy blooms and beautiful foliage. These plants can also thrive in pots, making them a versatile option for those with limited garden space or looking to add a pop of color to their patio or balcony. In this guide, we will walk you through everything you need to know to successfully grow a bigleaf hydrangea plant in a pot.

Selecting the Right Pot

When it comes to growing bigleaf hydrangeas in pots, selecting the right container is crucial. Choose a pot that is at least 12-16 inches in diameter and has drainage holes at the bottom. Bigleaf hydrangeas have shallow root systems, so a wide and shallow pot works best to accommodate their growth.

Ensure that the pot is made of a durable material like terracotta or plastic that can withstand the elements. Additionally, consider the aesthetics of the pot and choose one that complements the beauty of the hydrangea blooms.

Choosing the Right Soil

Bigleaf hydrangeas prefer well-draining, slightly acidic soil for optimal growth. Use a high-quality potting mix specifically formulated for acid-loving plants or create your own by mixing equal parts peat moss, pine bark mulch, and perlite.

Avoid using regular garden soil, as it tends to become compacted in pots and can hinder root growth. Ensure that the soil is moist but not waterlogged to prevent issues like root rot.

Planting Your Bigleaf Hydrangea

When planting your bigleaf hydrangea in a pot, fill the container with the prepared soil mix and create a hole large enough to accommodate the plant’s root ball. Gently remove the plant from its nursery container and place it in the center of the pot.

Fill in any gaps with additional soil mix and pat it down gently to secure the plant in place. Water thoroughly after planting to help settle the soil around the roots.

Providing Adequate Sunlight

Bigleaf hydrangeas thrive in dappled sunlight or partial shade. Place your potted hydrangea in a location where it receives morning sun and afternoon shade to prevent its leaves from scorching.

If you notice that your plant is not blooming as profusely as expected, it may be getting too much sun. Consider moving it to a spot with filtered light to encourage better flower production.

Watering and Feeding

Proper watering is essential for the health of your bigleaf hydrangea plant. Keep the soil consistently moist but not waterlogged, as these plants do not tolerate drought well.

Check the soil moisture regularly by inserting your finger into the soil up to an inch deep. If it feels dry, water your plant thoroughly, allowing excess water to drain out of the bottom of the pot.

During the growing season, feed your bigleaf hydrangea with a balanced water-soluble fertilizer designed for acid-loving plants every 2-4 weeks. This will provide essential nutrients for healthy growth and vibrant blooms.

Pruning and Maintenance

Pruning bigleaf hydrangeas is generally done after they finish flowering in late summer or early fall. Remove any dead or damaged branches, as well as spent flower heads to encourage new growth next season.

Additionally, consider repotting your hydrangea every 2-3 years to refresh the soil and provide ample space for root growth. Choose a slightly larger pot each time you repot to accommodate the plant’s increasing size.

Dealing with Common Pests and Diseases

Bigleaf hydrangeas are relatively low-maintenance plants but can be susceptible to common pests like aphids, spider mites, and powdery mildew. Keep an eye out for any signs of infestation and treat them promptly with insecticidal soap or neem oil.

To prevent fungal diseases like powdery mildew, ensure good air circulation around your plant by spacing multiple pots apart or placing them in an area with adequate ventilation.

By following these guidelines and providing proper care, you can enjoy lush foliage and abundant blooms from your bigleaf hydrangea plant grown in a pot. With their stunning flowers and compact size, these plants are sure to brighten up any outdoor space and bring joy to any gardener’s heart.
