Hydrangeas are beautiful flowering plants that can add a touch of elegance to any garden. They are easy to grow and care for, but many people are unsure about when they can plant hydrangea outside. In this article, we will discuss everything you need to know about planting hydrangea, including the best time of year to plant them, how to care for them, and more.

When to Plant Hydrangea

The best time to plant hydrangeas is in the spring or fall. This is when the soil is still warm, but the temperatures are cooler, which helps the plants establish their roots. If you plant hydrangeas in the summer, they may struggle to take root in the hot, dry conditions.

Spring Planting

If you choose to plant hydrangeas in the spring, wait until after the last frost has passed. This is usually around mid-April in most areas. Hydrangeas prefer soil that is rich in organic matter, so be sure to amend the soil with compost or other organic material before planting.

Fall Planting

Fall is also a great time to plant hydrangeas. Wait until the temperatures start to cool down, but before the first frost. This is usually around late September or early October in most areas. Be sure to water the plants regularly until the ground freezes to help them establish their roots before winter.

Choosing the Right Location

When planting hydrangeas, it’s important to choose the right location. Hydrangeas prefer moist, well-draining soil that is rich in organic matter. They also prefer partial shade, so avoid planting them in areas that receive full sun all day.

Soil Preparation

Before planting hydrangeas, prepare the soil by digging a hole that is twice the width of the root ball. Mix in compost or other organic material to improve the soil’s texture and nutrient content. Be sure to water the plant thoroughly after planting.

Caring for Hydrangea

Once your hydrangea is planted, it’s important to care for it properly. Hydrangeas require regular watering, especially during the hot summer months. They also benefit from a balanced fertilizer applied in the spring and fall.


Hydrangeas should be pruned in the late winter or early spring. Remove any dead or damaged branches, and cut back any old wood to encourage new growth. Be sure to also remove any spent flowers to promote new blooms.

Winter Care

In the winter, it’s important to protect your hydrangeas from the cold. Cover the base of the plant with a layer of mulch to help insulate the roots. You can also wrap the plant in burlap or other protective material to shield it from the wind and cold.


Planting hydrangeas can be a rewarding experience, but it’s important to do it right. By choosing the right time of year, location, and soil preparation, you can ensure that your hydrangeas thrive. With proper care and attention, your hydrangeas will provide beautiful blooms for years to come.
