Growing hydrangea tree has interested me for the past ten years since I grew my first hydrangea in my front yard. If you are like me and are keenly interested in this ornamental tree, you have come to the right place.
A hydrangea tree is a form of the hydrangea shrub trained to grow in a small tree form. The ornamental tree is famous in landscaping for its attractive and voluminous flowers, which blossom in different forms of colors like purple, blue, white, and pink.
If you desire to add a touch of gorgeousness to your landscape, this guide will show you how you can successfully grow this natural beauty in a few steps. Let’s get started.
How to Grow a Hydrangea Tree
Growing hydrangea is an interesting venture for people who love to see the good and natural beauty around them at a glance. Following these steps will help you have luxurious blossoms in no time.
1. Choose the Right Hydrangea Variety
When embarking on the journey of growing a hydrangea tree, the first step is to select a variety that gracefully lends itself to being trained into a tree form. Not all hydrangeas are suited for this, so choosing the right type is crucial.
- Panicle Hydrangea (Hydrangea paniculata): This variety is a top pick for many gardeners. Its adaptability, coupled with its ability to thrive in a variety of climes, makes it a flexible choice. The panicle hydrangea has cone-shaped flower clusters that change from white to rosy and pink throughout the season. Because of its robust stems and upright growth habit, it is perfect for training into a tree form.
- Bigleaf Hydrangea (Hydrangea macrophylla): Renowned for its large, vibrant blooms, the bigleaf hydrangea is a garden favorite. Because of their ability to shift color from rich pinks to deep blues based on the pH of the surrounding soil, their blossoms are extremely unique.
When trained as a tree, this type can be a magnificent addition to your yard, although it does take a bit more care and is better suited to milder climates.
2. Select the Planting Site: Creating the Perfect Environment for Growth
Selecting the ideal location for your hydrangea tree in your yard is similar to preparing the stage for a spectacular show. In their tree form, hydrangeas flourish in conditions that balance sunlight and shade.
Setting up the soil before you even get your hands dirty is an essential step in ensuring the success of your hydrangea tree. Ideal soil conditions facilitate rich flowers and vigorous growth.
- Well-Drained Soil: Trees love moisture but despise being waterlogged. The best soil for hydrangeas is well-drained soil to avoid root rot and other moisture-related problems. Consider amending your garden soil with organic material to improve drainage if it is heavy or clay-like.
- Sunlight and Shade: These trees thrive best in an environment that offers a mix of sun and shade. A location that basks in the gentle morning sunlight but transitions into dappled or partial shade in the afternoon is ideal. This balance helps promote robust bloom production while protecting the plant from the scorching heat of the day.
- Temperature Considerations:
While hydrangeas are relatively hardy, extreme temperatures can impact their growth and blooming. Providing additional afternoon shade can protect the plant from stress in regions with very hot summers.
- Nutrient Content:
Compost improves drainage and adds essential nutrients to the soil. Adding these nutrients is vital for the overall health of the plant, promoting lush foliage and abundant blooms.
- pH Levels and Bloom Color: Hydrangea trees have a unique trait—the color of their blooms can change based on the soil’s pH. For blue flowers, aim for a more acidic soil (pH below 6), and for pink flowers, aim for a more alkaline environment (pH above 7). You can adjust the pH by adding garden lime to raise it or sulfur to lower it, depending on your desired bloom color.
3. Planting: Setting the Roots of Your Hydrangea Tree
Planting hydrangea trees in the right way is vital for its growth. Here’s how to do it right:
- Digging the Hole: To begin, dig a hole twice as big and as deep as the hydrangea root ball. It gives the roots ample space to spread out and grow.
- Positioning the Plant: Gently place the hydrangea in the hole, making sure it’s at the same depth it was in the pot. Planting it too deep can stress the plant, while planting it too shallow can expose the roots.
- Backfilling: Carefully backfill the hole with soil, tamping down lightly as you go to eliminate any air pockets. This is an essential step in creating a sturdy foundation for your hydrangea.
- Watering: Once planted, give your hydrangea a generous watering. It assists in settling the soil around the roots and provides the necessary hydration to kickstart growth.
4. Staking and Pruning Hydrangea Tree
In its early stages, your hydrangea will require some guidance to take on a tree form.
- Staking for Support:Stake the main stem of your hydrangea to encourage it to grow upright. The stake should be sturdy and tall enough to support the plant as it grows.
- Training the Central Stem:Select a strong, central stem to serve as the trunk of your future hydrangea tree. It is the stem you will encourage to grow tall and strong.
- Pruning Away Excess Branches
Prune away any other stems or shoots that sprout from the base or lower part of the central stem. It focuses the plant’s energy on growing upward and developing a strong trunk. Pruning is essential for maintaining shape and encouraging new growth. So, the right time to prune hydrangea is in late winter or early spring.
5. Celebrating Blooms: Enjoying Your Hydrangea Tree
With proper care, your hydrangea tree will reward you with stunning blooms each season. These flowers make excellent additions to any garden or cut flowers in floral arrangements.
How to propagate hydrangea
Propagating hydrangeas is an exciting journey for garden enthusiasts. There are several methods to propagate these beautiful plants, each with its unique steps and benefits.
How to Grow Hydrangea From Cutting
Propagating hydrangeas from stem cuttings is not just a gardener’s favorite method; it’s almost like a fun little science experiment you can do right in your backyard! Let’s dive into the details of this method, known for its simplicity and effectiveness.
1. Choosing the Perfect Cutting
First things first, let’s play a bit of ‘plant detective’. Your mission is to find a healthy stem full of life that hasn’t bloomed yet. We’re looking for new, more pliable, and green growth here. This stem should be like the Goldilocks of branches—not too old or young, just right.
2. Preparing Your Cutting
Now, get ready to make a precise snip! Cut a segment about 4-6 inches long just below a leaf node using clean, sharp pruning shears. That’s the little bump where leaves emerge from the stem. Think of this as preparing a comfortable bed for roots to grow. Remember to strip off those lower leaves, leaving a couple at the top for the plant to breathe.
3. The Rooting Process: Magic Dust and a Cozy Home
Here’s where it gets magical. Applying rooting hormone powder to the cut end of your cut hydrangea stem encourages roots to sprout faster. Next, plant your stem in a moist, well-draining potting mix. Make sure to bury those leaf nodes; they will be the birthplace of your new roots.
4. Creating a Mini Greenhouse
Hydrangeas are like tropical vacationers; they love humidity. You can mimic that by covering your pot with a clear plastic bag or putting it in a humidity dome. It will create a cozy, humid environment, like a mini greenhouse. Just be sure to keep it out of direct sunlight – we’re aiming for a relaxing spa, not a scorching desert.
5. The Waiting Game: Root Development
Patience is key here. Wait for about 4-6 weeks for roots to develop. During this time, keep the soil moist but not soggy. Think of it as giving your cut a consistent sip of water, not a flood. After a while, gently tug on the cutting. If there’s resistance, congratulations – you’ve got roots!
Propagating Hydrangea Through Division
Division, in the world of hydrangeas, is like hosting a family reunion and then sending everyone home with a piece of the family heirloom. It’s a straightforward yet incredibly rewarding method of propagation. Let’s break down this process into simple, easy-to-follow steps.
1. Uprooting the Plant: Starting the Adventure
Think of uprooting your hydrangea as the beginning of an exciting adventure. To begin, carefully dig around the plant in a circle with a spade, being cautious not to damage the roots. It’s a treasure hunt; you’re gently excavating, uncovering the root system that’s been hidden underground. Once you’ve loosened the soil around the plant, gently lift it out. It’s a great moment to see the entire structure of your beloved hydrangea, from roots to shoots.
2. Dividing the Plant: Sharing the Love
Now, the real fun begins. Examine the root ball and look for natural separations. It’s like finding the seams in a well-made garment. Gently pull these sections apart, teasing the roots loose. Each division should have its own set of roots and shoots. It’s almost like you’re helping the plant start its own little family, ready to grow and flourish independently.
3. Replanting: New Beginnings
Once you’ve divided the plant, it’s time to give each new section a home. Plant each division in a spot that feels just right – ideally, in well-draining soil rich in nutrients. Water them thoroughly after planting. It is their welcome party, ensuring they settle comfortably in their new environment.
Growing Hydrangea By Layering Method
Layering is the gardening equivalent of a “set it and forget it” approach, with a dash of natural wonder. It’s a method that feels like helping Mother Nature while the plant is still cozy and connected to its parent. Let’s dive into the ins and outs of this relaxed yet effective propagation technique.
1. Scout for the Perfect Branch
First, you’ve got to play matchmaker and find the right branch for this propagation dance. Look for a healthy, lower branch on your hydrangea plant. This branch should have a gentle, can-do attitude, meaning it can easily bend to the ground without snapping. You’re looking for that sweet spot of flexibility and vigor – a branch that seems eager to reach and touch the earth.
2. Preparing Your Branch: A Little Nudge
Now, gently coax your chosen branch down towards the soil. Where it naturally touches the ground is your target area. Here, you’ll carefully make a small incision or notch on the underside of the branch. Think of it as a minor, encouraging whisper to the branch, saying, “Here’s where you can start your new journey.” This cut is crucial as it disrupts the outer layer, stimulating the branch to start thinking about growing roots.
3. Rooting: Securing the Future
With your branch nudged and notched, it’s time to anchor it into its new role. Use a garden stake, a heavy stone, or even a bent piece of wire to gently secure the wounded part of the branch into the soil. It is where your branch starts its transition from a limb to an independent plant. Cover the area lightly with soil to keep it stable and give it a good drink of water to settle everything into place.
4. The Waiting Game: Nature’s Slow Cooker
Patience is key in the layering process. It’s a slow cooker approach to propagation, where nature takes its sweet time. It could take several months for roots to develop from the notch. During this waiting period, keep the soil around the branch consistently moist but not waterlogged. Think of it as nurturing a slow-growing, underground secret.
Once you notice robust root growth at the incision site, it’s time for a mini celebration. Your branch is now ready to be cut free from its parent plant and begin life as a new, independent hydrangea. This new plant will be a carbon copy of its parent, carrying all the charm and beauty of the original.
Layering is an effortless, almost Zen-like way to propagate hydrangeas. It requires minimal fuss, a bit of patience, and a touch of curiosity. By the end, you will have a new plant that’s a living testament to the wonders of nature and the joys of gardening.
How to Grow Hydrangea in Pot
Gardening enthusiasts often wonder if it is possible to replicate the beauty of hydrangea within the confines of a pot. The answer is a resounding yes! Growing hydrangeas in pots is not only possible but can be incredibly rewarding. Here’s a detailed guide on successfully nurturing these stunning blooms in containers.
Selecting the Perfect Pot for Your Potted Hydrangea
The journey to a flourishing potted hydrangea begins with choosing the right container. A spacious pot, at least 18 to 24 inches in diameter, is ideal. This size provides ample room for root growth and helps maintain soil moisture. Equally important is ensuring the pot has good drainage. Hydrangeas love water, but they detest waterlogged roots, which can lead to root rot.
The Best Soil Mix for Potted Hydrangeas
Hydrangeas thrive in rich, well-draining soil. Opt for a high-quality potting mix and consider mixing in some organic compost. This combination ensures your hydrangea has the perfect blend of nutrition and drainage. Remember, the soil in pots can dry out faster than ground soil, so maintaining a balance of moisture retention and drainage is vital.
Dwarf Hydrangea Trees for Growing in Pots
When it comes to potted hydrangeas, size and growth habits matter. Compact varieties like the ‘Endless Summer’ series or dwarf types like ‘Pee Wee’ are ideal for container gardening. These varieties adapt well to the limited space of a pot and still produce full, vibrant blooms.
Sunlight and Location: Finding the Sweet Spot
Hydrangeas need the right balance of sun and shade, especially when grown in pots. The ideal spot is one that gets early sun and afternoon shade. It ensures the plant gets enough light to bloom without suffering from the harsh afternoon heat often noticed in a pot.
Caring for your hydrangea year-round, especially in the winter months, is crucial for your tree’s healthy growth.
Final Thought on Growing Hydrangea Tree
