The peegee hydrangea, a tall shrub or small tree native to Asia, does best in soils that are rich in organic matter, wet, well-drained, and exposed to full sun to partial shade. It grows quickly and can go up to 25 feet tall, although it can be cut down to keep a better shape. One of the toughest hydrangeas, it can withstand metropolitan environments. As blossoms appear on growth from the current year, prune in late winter. Deer are able to browse it.
Pruning the shrub to six to ten stems will promote the big creamy white flower panicles to develop even larger. The stems arch downward under the weight of the blossoms. Use in groups, as a hedge, or as a specimen plant.
How is a Pee Gee hydrangea tree planted?
Peegee hydrangeas should be planted in the fall, while planting in the early summer is also an option. In either full sun or light shade, Peegee hydrangeas thrive. Almost any type of soil will support their growth as long as it drains effectively and contains plenty of organic materials. The bloom color of this plant is unaffected by soil acidity, as is the case with all white hydrangeas. In order to plant a hydrangea:
- Make a hole that is half as deep but twice as wide as the nursery container it is in. It is not advisable to plant this shrub too deeply because doing so could cause root rot.
- After inserting the plant into the hole, add the previously removed dirt. To improve the soil generally and nourish the plant, think about incorporating manure and bone meal (or other sorts of organic matter).
- Around the just planted shrub, compact the ground. The soil should be able to hold the plant firmly in place, but it shouldn’t be compacted around the plant’s base or over its roots.
- After giving the plant plenty of water, mulch the shrub to aid in moisture retention.
Watering and Fertilizing
Regular watering is necessary since peegee hydrangeas require a lot of moisture. Dry weather is not good for these plants. For the first few years, water twice or three times a week. If there isn’t much rain, you should also water during the blossoming season. They will need additional water when it is extremely hot and dry. Fertilizer isn’t really necessary for this plant. Simply give it a light fertilizing in the early spring with a fertilizer designed for trees and shrubs.
Pruning Peegee Hydrangea Shrubs
Since peegee hydrangea blooms on new growth, it’s wise to prune this kind of shrub every year. By doing this, flower production will be increased. Prior to the plant beginning to grow new foliage for the upcoming flowering season, pruning is best done in late winter or early spring. Trim out any damaged branches as well as any that are poorly formed or cross over other branches in a way that would impede growth. Remove any old wood.
Training Peegee Hydrangea to Grow as a Tree
You must prune your peegee hydrangea differently if you want to train it to develop into a tree rather than a shrub.
- Start by selecting a robust, straight stem for the trunk. Stake the chosen stem while removing the majority of the others. Keep around four branches on the plant’s upper portion.
- When using this method, you’ll end up with a bushy upper portion on top of a stand-like trunk, which is referred to as constructing a “standard.” Tree roses are made using the same method.
- To keep your peegee hydrangea standard looking like a tree, you’ll need to prune it every spring. Remove non-trunk branches from the bottom of the plant and just round off the top of the plant.
Peegee Hydrangea Pests and Diseases
The Peegee hydrangea is a hardy shrub with little pest or disease issues. They occasionally draw mites or aphids, which are usually only a minor irritation. They occasionally may also experience minor problems with wilt, mildew, rust, or leaf spot, which can be treated by removing the offending foliage and/or using fungicide or other natural remedies. You might need to find a solution to stop deer or rabbits from nibbling on your plants if they live nearby.
Propagating Peegee Hydrangea
Any variety of hydrangea plant can be easily multiplied through cuttings. To make a rooted cutting, simply cut a branch off that doesn’t have any flowers on it. You can simply submerge the cutting in water and wait for roots to form, or you can root the cutting by dipping it in rooting hormone and planting it in garden pot soil.
Where should hydrangea trees be planted?
Hydrangeas in bloom are a surefire indicator of summer. Nothing compares to the stunning sight of hydrangeas in bloom in a range of colors. Every summer garden looks beautiful with the white, blue, pink, or purple blooms coupled with the vibrant green foliage.
How wonderful would it be to see hydrangeas on trees instead of the usual low-growing hydrangea bushes? The good news is that you can. How to grow a hydrangea tree is described here.
Instead of large spherical blossoms, the Grandiflora variety of Hydrangea paniculata develops white conical flowers. It has the potential to reach a height of 25 feet with moderate pruning and good maintenance! Your greatest option for cultivating a hydrangea tree is Grandiflora, also referred to as Pee Gee Hydrangea by gardeners.
Prepare yourself for success before you plant. The USDA plant hardiness zones 5 through 8a are ideal for hydrangea tree growth, so check your zone. Make careful to pick a location with consistent bright light because hydrangeas enjoy full sun for the majority of the day and a little afternoon shade.
Typically, hydrangeas prefer rich, permeable, moist soil. To promote healthy growth, aerate the soil with Espoma’s All-Purpose Garden Soil and apply Espoma’s Bio-tone Starter Plus. If you’re planting numerous trees, make sure to thoroughly water them and give each hydrangea a minimum distance of 3 to 10 feet.
Pruning is one of the most crucial aspects of hydrangea tree growth. The training, pruning, and correct maintenance are what distinguish a hydrangea shrub from a tree. Springtime is the best time to prune. Remove old twigs that failed to develop wholesome growths and suckers from the tree’s trunk. Trim branches so they have two or three nodes each to keep your tree looking tidy (small bumps on the branch that signify growth).
Although it requires a lot of sunlight, your hydrangea tree will offer some shade on particularly sweltering summer days. Keep the soil moist to prevent drooping leaves and blossoms because greater sunlight requires more water. Before the height of the growing season in the spring, prune your hydrangea tree.
Growing a hydrangea tree sounds like the next step for you if you love your hydrangeas and want to see more than a standard shrub!
When can a hydrangea tree be planted?
Choose a time in late spring or early fall when the nights are cooler and there is little risk of frost. If you garden in an area where the ground freezes, put seeds at least six weeks before the first deadly frost of the fall. This allows plants to establish roots before the ground becomes really cold. To improve root insulation, place a 2-inch mulch layer around plants after planting.
How is a little hydrangea tree planted?
Since hydrangeas are woodland plants, they require soil that is somewhat damp, rich in organic matter, and well-drained. Choose locations of your garden for planting that receive morning and afternoon sun, late-afternoon shade, and protection from high winds.
Without any protection from the sun, they are more prone to wilting and bleached leaves during the hot summer months.
Plant your hydrangea tree in the spring or fall, leaving 3 to 10 feet between each plant, in a hole that is twice as large and as deep as the root ball. If you’re transplanting a plant, be sure it is dormant and has lost all of its leaves and flowers.
If you are working with poor soil, add organic material to your planting spot and soak the roots of your hydrangea tree before planting.
How is a hydrangea tree supported?
With a soft plant tie, secure the hydrangea stem to the stake 18 inches above the ground, right below a leaf. The plant stem can be wrapped in a straightforward figure-eight loop that has been wound around the stake, crossed, and then gently pulled together and knotted. To allow the stem to continue growing, the grasp should be slack. As a plant tie, you can use a cotton cloth strip, a pantyhose strip, or jute twine. To assist it fit in with the bush, use a green tie, if preferred.
Why isn’t the Pee Gee hydrangea in my yard blooming?
All hydrangeas dislike dry weather and require regular watering to grow (or bloom) properly.
Try H. paniculata if you’re seeking for a variety that is more likely thrive in dry environments.
How far down do hydrangea trees go?
It’s simple to presume that a Hydrangea’s aggressive stem growth must be matched by an equally strong root system underground. However, the roots of hydrangeas are surprisingly shallow. They don’t develop a central taproot like shrubs and rhododendrons do. Instead, they develop in a slack, extending mass of fibers known as a “root ball.”
A hydrangea’s roots will spend the most of their time in the top six inches or so of soil. They do, however, have a tendency to expand widely in a horizontal direction. Many gardeners learned this the hard way when wayward Hydrangea stems started sprouting up far from the main body of the plant or invading their walkways.
As a general rule, you can assume that the roots of your hydrangeas extend at least a few inches past the dripline, which is the horizontal circumference of the leaves of the plant.
What is the rate of hydrangea tree growth?
When it comes to hydrangeas, rapid growth is defined as 25 inches or more of growth per year until the plant is mature. A “tree” format plant will reach a minimum height of 13 feet and a minimum width of 3 inches at a point 4 1/4 feet high.
How can I winter-proof my hydrangea tree?
Since I’ve been doing a radio show on Pittsburgh’s KDKA Radio for ten years, the most frequent query my co-host and I get is “Why doesn’t my hydrangea bloom?
Upon further enquiry, we invariably discover the caller is looking for information on Hydrangea macrophylla, a big-leaf hydrangea. These traditional hydrangeas produce lovely balls of pink or blue flowers, but in the northern United States, they are infamous for their unpredictability. They can blossom wonderfully one year and not have a single bud the following. Here are some suggestions you can implement right away to improve the blooms on your hydrangea if you’re a gardener in USDA zones 5 or 6 and have had similar experiences.
1. With very few exceptions, Hydrangea macrophylla cultivars like the double-flowered variety “Paraplu” develop their flower buds on ancient wood. This implies that the buds inside those seemingly dead twigs are actually the blossoms for the following year. Future blossoms are taken off if any branches are pruned now or in the spring. The optimum pruning method for big-leaf hydrangeas, according to my radio co-host and I, is to do none at all.
2. Cold temperatures and drying winds can harm the dormant flower buds trapped inside those brown sticks. The sporadic late-spring freezes are particularly harmful. Put a layer of protection around the plant to safeguard the dormant buds on your hydrangea. Each plant should have four 1×1 hardwood stakes hammered into the ground. Burlap or black landscape fabric should then be stapled to the posts surrounding each plant. Make sure the fence is as least as high as the plant. Avoid covering the top; the weight of any accumulated snow could cause the entire structure to topple over onto your plant. Till the hydrangea’s buds begin to swell in late spring, keep this protective castle in place.
3.Big-leaf hydrangeas typically perform better if placed in a more protected area. If at all feasible, move any non-blooming specimens to a corner that is shielded from strong winds and close to a road or wall that absorbs heat. The optimum times to transfer hydrangeas are in the early spring, before the leaf appears, or in the fall, just before the ground freezes.
4.You might want to think about including a couple different species of hydrangeas in your landscaping for more dependable bloom production. A slightly hardier form known as hydrangea arborescent develops enormous white flower clusters that resemble snowballs. My favorite cultivar is “Annabelle.” The oak-leaf hydrangea, H. quercifolia, is another extremely dependable bloomer with magnificent fall color and white conical blooms. However, there are a few cultivars of H. macrophylla that are currently available that have been chosen for their ability to bloom on both old and new wood. With a more recent introduction dubbed “BloomStruck,” I’ve had the most success.
What is your favorite hydrangea, and how do you keep it safe during the winter?
How big can hydrangea trees grow?
Check your hardiness zone if you’re thinking of growing hydrangea trees. Plant hardiness zones 5 through 8a of the U.S. Department of Agriculture are ideal for growing tree hydrangeas. They can reach heights of 25 feet (7.6 meters) and widths of 20 feet (6 meters) when planted properly.
According to tree hydrangea information, this plant has dark green, deciduous leaves that drop off in the fall. The largest leaves can grow to be 3 inches (7.5 cm) wide and 6 inches (15 cm) long.
Expect nothing resembling a fall show; the leaves hardly turn yellow before falling. The magnificent blooms, however, make up for the lack of fall color.
Panicle growth of the flowers can reach 8 inches (20 cm) in length. They begin as cream-colored blossoms on the trees and later turn purple or deep pink as they ripen. The flowering of tree hydrangeas is abundant. Often, the weight of these flowers causes the tree’s spreading limbs to lean toward the earth.
