The majority of hydrangea species are largely free of pests and diseases. To avoid such problems, though, regular monitoring will be necessary during the growing season.
In areas that endure extreme heat, irrigation may also be necessary to prevent plant leaves and flower flowers from wilting.
Pruning will be required, much like with other hydrangea plants, to encourage bloom and preserve shape. Because these plants only produce blooms on new growth, you must clip branches at the proper time of year. It is best to prune PeeGee hydrangea trees in the late winter or early spring before new growth has started.
How should PeeGee hydrangeas be winterized?
The generic name “Pee Gee” for the panicle hydrangea, Hydrangea paniculata, is derived from the earlier cultivar, Hydrangea paniculata “Grandiflora” (PG). On the growth from the current year, Pee Gee’s elongated flowerheads bloom all summer long like the snowball blooms of H. arborescens. Panicle hydrangeas, one of the hardiest varieties, are found in USDA plant hardiness zones 3 to 8, however they do not thrive in areas where winter cooling does not result in freezing temperatures. Although these resilient plants require little winter preparation, they could benefit from modest yearly assistance against drying winds.
Depending on the environment in your area, you should cease fertilizing hydrangeas in August or in the early fall. Cooler areas, such USDA plant hardiness zones 3 and 4, should discontinue summer care in August to get the plants ready for dormancy.
Cover the shallow roots of H. paniculata with a winter mulch that is 3 to 4 inches thick and made of wood chips, leaves, well-rotted compost, or a mix of these. Mulch only after many severe winters have destroyed soil-borne fungus and bacteria. To shield the plant’s crown from the harsh winter winds and sunlight, pile mulch around the plant’s base.
Once the plant has lost all of its leaves and you’ve seen multiple harsh freezes, prune branches back to between one and two feet from the main stem. Trim the main stem of the shrub approximately 1/2 inch above a bud facing outward, and branches will develop outward rather than crowd the center the next year. This will prevent stubby ends. Pruning shrubs can be done at any time throughout the late winter, although it is more comfortable to do so before the biting cold of the season comes in.
On aged wood, do PeeGee hydrangeas bloom?
On fresh wood, panicle hydrangeas can also blossom. Since they won’t be producing new growth, they can be clipped in late winter or early spring. Depending on the size of the plant you wish to keep, cut them down to the ground or just a few feet above the ground. PeeGee and Limelight are two of the most well-known panicle hydrangea varieties.
What occurs if your hydrangeas aren’t pruned?
If and when you prune is the key to happy, healthy hydrangea flowers. Of course, fertilizing and offering the ideal environment have a lot to recommend them. However, if you don’t prune properly, your efforts will be in vain. Deadheading is not the same as trimming. Pruning refers to more drastic cutting to preserve shape or remove dead growth. However, feel free to discard spent blossoms or cut fresh ones to use in arrangements.
Hydrangeas can bloom on either fresh wood or old wood, depending on the species. The wood from which they blossom determines whether and when to prune.
Old wood-blooming hydrangeas do not require pruning and benefit from it. They’ll blossom more abundantly the next season if you leave them alone. But feel free to deadhead or gently thin. Just keep in mind that while new growth may appear, it won’t bloom until the following season. In our region, four different species blossom on aged wood. Additionally, they are not limited to the hues displayed here.
Climb using suckers. On your wall or trellis, resist the desire to remove the dormant growth.
The flower heads are more conical in appearance, and the leaves are large and resemble oak leaves. It’s a pleasant surprise for a hydrangea when its leaves turn reddish-orange in the fall.
They are very comparable to lacecap types, but smaller and with more compact leaves.
Pruning should be done in late winter or early spring on hydrangeas that bloom on new wood. Trim back to two feet to prune to shape. The next season’s blossoms are produced by strong, fresh growth that is encouraged by trimming. In our region, there are two types that bloom on fresh wood. They are also not restricted to the colors displayed.
Oakleaf variants are not included in cone-shaped blooms. Keep the blooms on throughout the winter to provide interest; even dried out, they are quite lovely.
regarded as a wild kind. They often have smaller blooms and leaves than Bigleaf variants and are completely white. They enjoy full sun and can grow very tall.
Knowing whether or when to prune now will help you avoid the disappointment of a hydrangea that doesn’t blossom. Don’t forget that a robust shrub will produce more gorgeous blossoms if it has well-draining soil and good organic fertilizer. Come on in, and we’ll show you where to go to develop your green thumb.
Peegee is a what kind of hydrangea?
Even if you are unfamiliar with the sing-song name of this shrub, you have probably seen this stunning hydrangea in one or more Southern gardens. Hydrangea paniculata, which can be a shrub or a small tree, is the source of the popular variety known as peegee hydrangea. One of the most well-known and frequently cultivated panicle hydrangeas, it is also referred to as “Grandiflora.” It can be trained to reach heights of up to 25 feet tall, but it is most frequently found growing at heights of 10 to 15 feet tall and 8 feet wide. Peegee hydrangea is frequently planted as an upright tree. It can be planted as a hedge because of its height and spread.
Peegee hydrangeas have lovely foliage with dark green, oval leaves that finish in points and turn bronze in the fall. One of the main reasons to plant Peegee hydrangea is that it also produces eye-catching white blossoms throughout its flowering season. Large white flower clusters open up in a magnificent shower, but as they become older, they start to turn pink, golden, and brown.
This hydrangea grows best in wet, well-drained soil with frequent watering in full sun or light shade. It is a tough, quickly expanding plant that is extremely attractive when it blooms. Because Hydrangea paniculata blooms on new growth, late winter pruning is necessary. Because it is so simple to cultivate and is a somewhat tolerant shrub in terms of maintenance and habitat, this hydrangea is perfect for beginners.
Peegee undoubtedly adds attractiveness to the garden. If you enjoy peegee hydrangeas, you may also enjoy ‘Kyushu,’ which bears white flowers, ‘Limelight,’ which has vibrant green blooms, and ‘Interhydia,’ also known as Pink Diamond hydrangea, which has pink buds and large flowers that turn cream to red throughout the course of the blooming season.
In your yard, do you have any peegee hydrangeas? Will you be planting some this year?
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.
Should I remove the brown blooms on my hydrangea?
Your hydrangea shrubs’ blossoms appear to be withering or turning brown. No need to worry—this is merely a signal that it’s time to deadhead—remove the blossoms from the plant.
Deadheading hydrangeas doesn’t cause any damage to the plants at all. Flowering shrubs stop producing seeds when the spent blooms are removed, and instead focus their efforts on developing their roots and leaves. You will be doing your hydrangeas a favor by deadheading because this strengthens and makes plants healthier.
When should I prepare my hydrangeas for winter?
Here is professional guidance on how to put hydrangeas to bed for the winter season from guest bloggers Megan Nichols and Jessie Jacobson of Tonkadale Greenhouse in Minnetonka, Minnesota. (They may have more hydrangea trees and shrubs in their zip code than almost anywhere else in the United States, so they are aware!)
The temperature has dropped, and autumnal symbols can be seen everywhere. The garden needs to be put to bed soon. Hydrangeas reward us with large, stunning, and prodigious blooms all season long. You may say that they are givers. It’s time to return the favor now. It’s time to tuck the hydrangeas in with kisses and wishes for sweaty dreams.
Here in Minnesota, our moods can fluctuate as drastically as the unpredictably harsh winter weather extremes, snowfall, and freeze/thaw cycles. Despite the fact that many hydrangeas are regarded as hardy, all of this can confuse them. To survive the winter and come back bigger and better the next year, they require some care. Although hydrangeas cultivated in warmer areas don’t need as much post-season primping as those grown in our zone, there isn’t a single thing that wouldn’t appreciate a little tender loving care right now.
Utilize these suggestions to get the most out of your hydrangeas so that you can be the one to present at this time next season!
(Is pruning in order? No and yes. Here is our recommendation for which hydrangeas should be pruned right away and which should wait until spring.)
Don’t Stop Watering
Make a commitment! I shall water my hydrangeas till the earth freezes solid, you declare while raising your right hand. really good Hydrangeas are thirsty plants by nature, so it’s essential to give them regular, deep watering. We don’t need to get all linguistically nerdy right now, but their name literally means “hydration.” Winter’s cool, dry winds completely drain the moisture from the vegetation, and hydrangeas don’t use lip balm. It need not be heated in order to be dry!
If a freeze is not a concern where you live, water deeply but sparingly during the winter depending on how much rain you get.
This is how: Making a small hole in the side of a 5-gallon bucket, filling it with water, and placing it at the base of the plant while it slowly drips out of the bucket is one method. Another option is to lay your hose at the base of the plant for about an hour with the water turned on to a gentle drip.
Give Them One Last Hearty Meal
Composting your hydrangea beds in the fall will give them a boost for the upcoming growing season. Everyone feels better after a full night’s sleep and a filling breakfast. This also applies to hydrangeas. After a lengthy winter’s hibernation, they will be ravenous for some nice compost. Compost can decompose during the winter if it is used now, making nutrients easily accessible in spring. A few inches of compost is advisable even in regions without a deep cold. Only compost is being discussed here! Don’t give your hydrangeas fertilizers that are high in nitrogen because this can encourage them to produce new foliage growth.
This is how: Before laying down mulch in colder climates, top dress the area with compost, well-aged manure, or other organic material after the ground has frozen. This organic fertilizer, which is rich in nutrients, will decompose over the winter, making nutrients available to the plant in the spring. Apply compost in the late fall or early winter in zones that are warmer.
Mulch Matters
Mulching helps keep moisture in and weeds out in warmer climates while shielding the crown and roots of your hydrangeas from harsh winter temperatures in colder climates. Snow serves as a natural insulator if everything goes as it should. Plants suffer during strange winters with little snowfall and extreme temperature changes. Apply a thick layer of mulch around the plant’s base to offer hydrangeas the best chance of flourishing. While decorative mulch is useful, straw, marsh hay, or dead leaves are suggested instead.
This is how: Apply a 6–8 layer of mulch once the ground has frozen (or late fall or early winter in zones with milder winters). This shields plants from the heave-ho of springtime freeze/thaw cycles, which can yank them out of the ground. Inviting mice to make this their snug winter home, causing rotting and illness, or tricking the plant into believing it’s time to bud, are all consequences of mulching too early. Be patient; you don’t have to do things early simply because your neighbors are.
Keep Them Cozy
The amount of winter cold determines whether or not hydrangeas require protection. Winter protection is not required in zone 7 if the air temperature stays above zero degrees. Wrap or totally cover barely hardy hydrangeas in chilly areas. This is crucial for plants that bloom on old wood, such hydrangeas with mop heads and large leaves (Hydrangea macrophylla). The most recent types of mop head/big leaf hydrangeas, however, bloom on both fresh and old wood, so it’s important to keep that in mind. In their favor and ours! Hardier hydrangea varieties like the paniculata and arborescens don’t often require additional winter care, although really low temperatures might cause its limbs to die back. Consider covering if a colder than usual winter is forecast.
This is how: Wrap plants loosely in a few layers of burlap, making sure to tie it off with strong twine. Making a mulch mountain and covering the majority of the plant is an additional choice. Smaller, newly planted specimens respond well to this technique.
There’s Still Time To Plant!
The first three varieties of hydrangeas can be grown here in Zone 4; oak leaf hydrangeas can also be grown in warmer climates (zones 5 to 9). The optimal time to plant shrubs is in the fall. Just make sure to do all of the aforementioned things, including watering and mulching.
Here are some of our favorites that you can plant now for stunning blooms the following spring.
Panicle Hydrangeas
These late blooming hydrangeas, sometimes known as PeeGee hydrangeas (summer into early fall). They are covered in elongated, conical flower heads that emerge white or green and blush into pinks and peaches as the season goes on.
How is a Peegee hydrangea fertilized?
Panicle hydrangeas are the most sun-tolerant hydrangeas, and in cooler locations (like USDA zones 3-6), we advise at least four hours of full sunlight each day; six or more is desirable since it promotes the healthiest stems and the most flowers. Even though the plants should receive at least some sun each day, afternoon shade is advantageous in hotter locations (USDA zone 7 and warmer).
Panicle hydrangeas are generally not picky about soil, but excellent drainage is essential. Avoid growing them in any region where it is consistently damp because this can cause root rot. Other than that, any common soil in your garden would do. Even clay soil can support their growth if it is well-drained. As a result, unless you reside in a region with extremely acidic or alkaline soil, you shouldn’t need to make any adjustments to successfully produce panicle hydrangeas.
When planting panicle hydrangeas, avoid adding any soil amendments. When planting in the ground, don’t fill the hole with any type of compost, potting mix, top soil, etc. This results in something known as the “bathtub effect: When you add an amendment, water seeps in very quickly, but as it drains and contacts the surrounding native soil, it slows to a stop. It remains around the roots throughout this time, making them vulnerable to rot. This is the number one reason we’ve observed that recently planted panicle hydrangeas could struggle, so it bears reiterating here even though it is our advise for planting all of our shrubs. Make life simple for you and your new plant by planting just into your natural soil, watering immediately after planting, and mulching with 2-3/5-7 cm of finely chopped bark.
Panicle hydrangeas require constant watering throughout their first year or two of growth, much like any freshly planted shrub or tree. They can tolerate dry circumstances after they are established, but very hot, dry weather might hinder blooming, thus regular watering is advised for the most and prettiest flowers.
Panicle hydrangeas typically don’t need to be fertilized on a regular basis. A springtime application of a granular shrub fertilizer (like a rose fertilizer) will do if you want them to grow more swiftly. Avoid over-fertilizing panicle hydrangeas as this can result in brittle stems. Be especially cautious of inadvertent fertilizer, such as that provided to a neighboring grass or flower bed, as they frequently contain high nitrogen levels and are more likely to promote weak stems through quick, soft growth.
“The word “panicle” refers to the plant’s blossoms’ arrangement and shape, although it’s best to picture them as about football-shaped (and large!). In zones 8/9, mid-late April is when they blossom. The blooms begin the summer season white, but as the season progresses, the days begin to grow shorter and the nights become cooler, the blossoms begin to take on pink to red tones. The specific hue will vary according on the variety; some may completely change color, while others will do so gradually, creating a multicolored shaded impression. Muddy-colored blossoms often signal that the plant is receiving too much shadow and/or that temperatures, especially at night, have been too hot.
The color that the blooms take on is a genetic feature that emerges with the normal aging of the floret cells and is unaffected by any soil factor, such as pH level. Panicle hydrangeas’ color cannot be altered by growing them in acidic soil or applying aluminum sulfate; they will always remain in the pink/red spectrum.
Panicle hydrangeas require little to no winter care because they can withstand freezing temperatures so well. It is ready to withstand the next cold, ice, snow, and wind as long as a thick 2-3/5-7cm layer of mulch is over the roots.
On fresh wood, panicle hydrangeas blossom.
In other words, they don’t start producing flower buds until the spring, once they’ve started to leaf out. This means that pruning them won’t have an adverse effect on how well they bloom. Despite not being strictly essential, pruning promotes stronger stems, better blooming, and an all-around more beautiful shape. Keep trimming to a minimum while the plant is still young and hasn’t had a chance to grow a strong body if you are starting with a very small plant, like one you bought online.
When to prune: Panicle hydrangeas can either be pruned in early spring, right as the new growth starts to emerge, or in late fall, after the plant has completely gone dormant (i.e., has shed all of its leaves and has been bare for at least two weeks). Aim to reduce the plant by roughly one-third of its total height, or roughly 2′ if it is 6′ tall. You should also remove any side branches and thin, spindly stems.
