How Deep Do Hydrangea Roots Grow

Fact Checked By | Post Updated On:

Hydrangea roots are not very deep, typically only growing to about 18 inches. This is good news for gardeners who want to plant them near walkways or other shallow-rooted plants. However, they do spread laterally, so it’s important to give them room to grow.

When planting, be sure to dig a hole that’s twice the width of the root ball.

Hydrangeas are a type of flowering plant that is native to Asia and North America. There are many different species of hydrangea, and they come in a variety of colors including white, pink, purple, and blue. The flowers of a hydrangea are typically large and showy, and the plant itself can grow to be quite large, with some species reaching up to 10 feet in height.

Hydrangeas are popular garden plants, and they are often used in landscaping and as ornamental plants. The roots of a hydrangea can grow quite deep, depending on the species. Some species have roots that can reach up to 6 feet in depth, while others have shallower roots.

The depth of the roots can also vary depending on the soil type and the climate. In general, though, hydrangeas have deep roots that help to support the plant’s large size. The deep roots of a hydrangea are one of the reasons why the plant is so resistant to drought.

The roots are able to reach down into the soil to access moisture, even when the surface of the soil is dry. This means that hydrangeas can withstand periods of drought better than many other plants. If you are thinking of planting a hydrangea in your garden, make sure that you have enough space for the plant to grow.

Hydrangeas can spread quite wide, and they need room to develop their deep roots. With proper care, a hydrangea can be a beautiful and long-lasting addition to your garden.

This is why these types of hydrangeas are often used as ground cover. The roots of tree hydrangeas, on the other hand, are deep and thick. This is what allows tree hydrangeas to grow tall and sturdy.

So, when it comes to hydrangea roots, it all depends on the type of hydrangea you have. Mophead and lacecap hydrangeas have shallow roots, while tree hydrangeas have deep roots.

How deep do hydrangea bush roots grow?

Will hydrangea roots damage pipes?

Hydrangea roots are not known to damage pipes. In fact, they are often planted near pipes and other underground utilities because they are shallow-rooted and not aggressive. However, it is possible for the roots to clog pipes if they are growing in the same area.

If you are concerned about hydrangea roots damaging your pipes, it is best to consult with a professional landscaper or horticulturist.

How to stop hydrangeas from spreading

Hydrangeas are a beautiful addition to any garden. But if you’re not careful, they can quickly take over your yard. Here’s how to stop hydrangeas from spreading:

1. Cut back the plant in early spring. This will help to control its growth. 2. Mulch around the base of the plant.

This will help to prevent new shoots from forming. 3. Pull up any new shoots that do form. This will prevent the plant from spreading.

4. Apply a herbicide to the base of the plant. This will kill any new shoots that form. With a little bit of effort, you can keep your hydrangeas under control.

Do hydrangeas spread on their own

Hydrangeas are a type of flowering shrub that comes in a variety of colors. They are a popular choice for gardens and landscaping because of their showy blooms and easy care. Hydrangeas are relatively low maintenance and can even spread on their own, making them a great choice for gardeners of all levels of experience.

While hydrangeas can spread on their own, they will need some help to get started. The best way to encourage spreading is to plant hydrangeas in an area that gets plenty of sunlight and has well-drained soil. Once the plants are established, they can be left to their own devices.

Hydrangeas typically spread through a process called runners. This is when the plant sends out new shoots that take root in the ground and eventually form new plants. Runners can be encouraged by trimming the plant back after it blooms.

This will encourage the plant to put more energy into forming new runners. Once hydrangeas start spreading, they can be a bit of a nuisance if not kept in check. They can quickly take over a garden bed if left unchecked.

Gardeners who want to control the spread of their hydrangeas can do so by regularly trimming back the runners. This will keep the plant in bounds and prevent it from taking over the garden. Overall, hydrangeas are a great choice for gardeners who want low-maintenance plants that will add color and interest to their landscape.

While they can spread on their own, a little bit of trimming will help to keep them in check.

How deep do hydrangeas need to be planted

If you’re planting hydrangeas in your garden, you’ll need to know how deep to plant them. Hydrangeas need to be planted at least 18 inches deep, and preferably 24 inches deep. This will ensure that the roots have enough room to grow and the plant will be stable.

It’s important to plant hydrangeas at the right depth so that they can thrive in your garden.


Hydrangea roots typically grow to a depth of 18 inches. However, the depth of the roots can vary depending on the type of hydrant used.
