Hydrangea trees are a stunning yet elegant addition to any landscape or garden. Hydrangea trees are shrubs that are pruned to look like trees to create an eye-catching plant that is beautiful to look at. You’ll have what looks like a tree covered in bright clusters of flowers. You’ll want to plant these near a sitting area so you can enjoy them day after day.

Hydrangea trees, sometimes called a hydrangea standard, reach a medium height and width, so they shouldn’t take over any areas. You can plant them along walkways, near mailboxes and patios, in containers, or by themselves. They work well as accent plants or focal points, so they’re sure to fit somewhere in your garden. 

We offer several gorgeous types of Hydrangea trees that we’re confident you’ll love. If you want subtle color, our Limelight Hydrangea blooms white and pale green. If you want something more striking, you’ll love the bright pink and white that the Fire Light Hydrangea boasts. 

Hydrangea Trees Care Overview

Hydrangea trees are easy to care for if you can water them regularly and provide enough sun. These trees prefer full sun or partial shade. If keeping moist soil will be challenging, the partial shade will be the better option. 

Annual pruning is recommended, although you don’t have to do this to see new blooms each year, making it a low-maintenance plant.

The flowers will bloom in spring and summer and occasionally in fall. Once the temperatures cool and the flowers stop blooming, expect to see a beautiful display of fall foliage.

Hydrangea Tree Bloom Time

Hydrangea trees will bloom in mid-summer and continue flowering until the frost. Their white blossoms will change to pink or red as the days get shorter and the nights cooler. A dependable performer, hydrangea trees will bloom every year.

Growing Hydrangea Tree In Pots

Hydrangea trees can do very well in a large container on a deck or patio. This can be a great option if you live in a cold region and are not sure a hydrangea tree would survive your winters. 

Choose a large pot with suitable drainage holes. When overwintering, check to ensure the soil has not entirely dried out. You may need to water it gently to keep the soil slightly moist (it dries out quicker in above-ground containers) even though the tree is dormant.

Information on Planting Hydrangea Trees

Wondering when to plant hydrangea trees? Spring is the best time of year to plant Hydrangea trees. You can also plant them in the fall, but a spring planting will give them an entire growing season to develop a sturdy root system allowing the plant to grow well the following year.

Hydrangea standards enjoy full sun but will grow in partial shade. In hotter climates, a little afternoon shade is helpful to shield them from the full effects of the more powerful afternoon rays. They are tolerant of many soil types and can even withstand some salt.

Dig a hole deep enough that the root ball will be covered but be sure not to dig any deeper. The width should be double the height of the root ball. Fill in the hole with well-draining soil and water deeply. Keep the plant well-watered during its first year to establish a strong and deep root system.

How To Propagate Hydrangea

If you’d like to turn your hydrangea tree into two hydrangea trees, you can propagate it. During the spring when the plant is in bloom, remove some healthy stem cuttings that are a little under 6” long. Place the stem cuttings into some damp potting mix and keep them watered for the next few weeks while giving them partial sunlight. After a couple months of growing in a pot, your young hydrangea plants will be ready for the garden.

Hydrangea Tree Zone

Most Hydrangea trees are suitable for USDA zones 3-9, which cover most of the US. The one exception is the Pink Diamond Hydrangea Tree, which is only recommended up to zone 8.

Do Hydrangea Trees Need Full Sun?

Hydrangea trees can sometimes grow in full sun, but some partial shade is preferred. Most hydrangeas enjoy the morning sun but may struggle with the constant afternoon sun in warmer climates. Try to find a place for your hydrangea near a taller tree that will soak up some of the sun throughout the day.

Hydrangea Tree Size

Hydrangea trees grow 6 to 10 feet tall and 3 to 6 feet wide. Since the width is at the top of the plant, you can plant them along paths or seating areas without worrying about hitting your head on the branches. If you grow your tree in a container, it may create a smaller plant, so this is something to consider when planning your space. Potted hydrangea can be moved into the ground at another time if desired.

Do Deer Eat Hydrangea Trees?

Hydrangea trees are not deer resistant. Planting hydrangeas around your property will not prevent deer from wandering into your yard. In fact, many deer will graze on the leaves and flowers of some hydrangeas, so if you’re into wildlife observation, hydrangea trees will not impede on your ability to do so.

How Much Water Does A Hydrangea Tree Need?

Hydrangea trees are thirsty, so expect to water them often, especially if you live in a hot climate and provide your plants with full sun. If your tree receives partial shade, you likely won’t need to water as often. It needs moist soil, so check it often to make sure the soil isn’t drying out.

Water the plant deeply at the base. New transplants typically need more water than older trees, so long and frequent waterings will be extra important the first year the plant is in your garden. A generous layer of mulch at the base of the plant will help the soil retain moisture and reduce how often you have to water. 

What's the Best Fertilizer for Hydrangea Trees?

Hydrangea trees benefit from an annual dose of slow-release fertilizer in early spring. Apply the fertilizer as the package directs at the base of the plant. This kind of fertilizer will feed the plant all year long and encourage more flowering, stronger roots, and shiny foliage.

How to Prune Hydrangea Trees

Pruning your Hydrangea tree in late winter or early spring before new growth emerges is the safest time to avoid removing this year’s blooms. Hydrangea trees develop new flowers on new growth, so you need to remove old growth and avoid new limbs.

Pruning isn’t necessary but will help your plant look tidy and elegant. You can prune off all old growth if you wish or only remove the branches that affect the overall shape of your tree.

You can also prune your hydrangea tree in late fall when the plant still has leaves so you can decipher the old growth from the new.

Tree hydrangeas won’t develop their flower buds for the current year until they leaf out in the spring.

Don’t worry about pruning off your flower buds in early spring, as can happen with Bigleaf hydrangeas, which flowers on buds set last fall. As long as you prune before leaf emergence, you’ll be alright.

Hydrangea Trees In Winter

As panicle hydrangeas are pretty hardy, they should not require anything special to over-winter, as long as they are hardy in your USDA growing zone. Keep them mulched, but don’t allow the mulch to contact the trunk. 

If growing in a container, buy a tree hydrangea that is hardy to at least one, if not two, zones colder than your zone. Or, bring the tree inside overwinter and shelter it in a garage or other area that is a bit warmer than the outside temperature.
