Hydrangeas produce beautiful, vividly colored blossoms on globe-shaped flower heads, and they are frequently presented as gifts during the spring holidays. The United States National Arboretum claims that Hydrangea macrophylla is the most widely cultivated species in the country. Hydrangeas make excellent indoor plants and may be grown outdoors in U.S. Department of Agriculture zones 6 through 8. If you received a potted hydrangea as a present, it was probably already in bloom. After the petals first fade, many people throw away their hydrangeas, but with the right care, the plant will bloom once more.
What do I do with my hydrangea in a pot over the winter?
Bring potted plants indoors before the first frost for the greatest hydrangea winter protection. They can stay outside and be protected by covering the entire pot and plant if they are too heavy to transport. Foam insulation is one way to safeguard your potted plants.
How long do hydrangeas in pots last?
In U.S. Department of Agriculture hardiness zones 5 through 9, hydrangea (Hydrangea spp.) gardens are adorned with enormous, vibrant blooms. These shrubs, which share their frothy blossoms for the most of the summer and may grow between 4 and 12 feet tall with proper care, can live for decades.
Hydrangeas are hardy shrubs that, with proper care, can survive for up to 50 years. They require frequent watering during the growing season and prefer early light but afternoon shade. After the blossoms have faded, prune them in the fall so that they will have sturdy stems for the summer after. The hydrangeas may lose their blooms for a year while the plants heal if they are pruned when they are in bloom.
Common hydrangeas, sometimes known as bigleaf hydrangeas, bloom in a variety of hues, including blue, pink, and purple. These hydrangeas typically start to bloom in May, which is sooner than some other kinds. Usually, the plants keep producing blooms until July. According to the characteristics of the soil, bigleaf hydrangeas are known to shift their bloom colors; a plant that blooms pink one year may bloom blue the following. Aluminum sulfate, which is added to the soil, promotes blue flowers, whereas hydrated lime, which is added to alkaline soils, promotes pink blossoms. Ayesha, Nikko Blue, and Preziosa are cultivars.
Longer blooming than other hydrangeas, the smooth hydrangea (Hydrangea arborescens) frequently displays color from early June through September. The cultivars “Anabelle” in white and “Invincibelle Spirit” in pink are examples. Smooth hydrangeas often bloom on wood from the current year, which means you should severely prune them, in contrast to other hydrangeas that bloom best on ancient wood. Trim them to a height of 6 to 12 inches above ground.
The panicle hydrangea (Hydrangea paniculata) blooms later in the year because it prefers the heat of summer to the mild weather of spring. Panicle hydrangeas often begin blooming in July and continue through September. Their blossoms are initially white, but as fall approaches, they start to turn rusty pink.
However, if you relocate the plants or transplant one from a pot to the ground, the hydrangeas may not bloom for a year or perhaps two. Hydrangeas can produce big flowers in their first year. This does not imply that their time of flowering is over. Once the roots of the plants have recovered from the shock of transplantation, they should begin to blossom. To this end, keep the plants well-watered and treat them with a balanced fertilizer throughout the spring, summer, and fall.

If deadheaded, do hydrangeas bloom again?
Hydrangeas cannot be revived by deadheading like other flowers can. Reblooming hydrangeas produce a second set of flowers on fresh stems later in the season compared to regular kinds, which only bloom once each season. When deadheading hydrangeas, the goal is to keep the shrubs looking tidy and to direct plant growth toward roots and leaves rather than seeds.
Can I put my hydrangea plant in a pot outside?
Mophead hydrangeas can be cultivated outside wherever the wintertime temperature stays above -15oC because they are hardy (5oF). However, as they were grown in greenhouses and given fertilizer to induce early flowering, potted hydrangeas sold as houseplants may require some time to acclimate to life outside before being put out. Place them outside in their pots during the day and bring them inside at night to harden them off for one to two weeks before to planting. Hydrangeas that have been grown for outdoor planting can be planted immediately. Mid- to late April, when the soil has had time to warm up, is the ideal time to plant mophead hydrangeas outdoors.
The optimal conditions for hydrangeas are shade from the sweltering afternoon sun and moist, well-drained soil. They are therefore excellent alternatives for shady gardens, and in mid- and late-summer, their dramatic spherical flowerheads are absolutely gorgeous. Regularly water hydrangeas, especially during dry spells, and in the spring or fall, mulch with compost or other organic material.
Because of the soil’s pH (acidity or alkalinity), pink and blue mophead hydrangea blossoms have the unusual ability to change color. The blossoms will be a deeper shade of blue the more acidic the environment is. Flowers turn a gorgeous pink on alkaline soil. The color of white mophead hydrangeas doesn’t alter.
Can hydrangeas grown in containers spend the winter outside?
You’ll be relieved to learn that winter maintenance needs little work. The best place for your hydrangeas to spend the winter is outside, so now that you’ve put them inside the garage, you may carry them back there.
Hydrangeas are quite cold hardy, thus in the majority of hardiness zones you may leave them on your patio unprotected. Some people can survive in zone 2, where it can reach as chilly as -40 C, perfectly well! Ouch. Although they can all withstand a certain amount of cold, each hydrangea has a different tolerance, so be sure you have a variety that is suitable for your region. Additionally, zone up if you are planting in a container! (See underneath.)
Make sure the containers they’re placed in have enough drainage, as the plants can suffer major harm from inadequate drainage. If not, your hydrangeas will flourish just fine and require the same upkeep and attention as they would in a garden.
Zone up those container plants
Zone up for success if you intend to grow a perennial in a pot! Your plants are less protected from the cold in a container than they would be on the ground. So, for instance, if you are in zone 4, I would advise choosing a plant species that is hardy to zone 3.
How can a potted hydrangea be kept healthy?
Remove any foil wrapping from the hydrangea if it was a gift. Remember that hydrangeas offered for sale around the holidays might not be hardy enough to endure indoors. If you’re serious about growing hydrangeas indoors, your chances of success may be higher if you buy them from a nursery or greenhouse.
Place the hydrangea in a sizable pot filled with superior potting soil. Put the plant in an area with lots of light. Hydrangeas planted outside can take some mild shadow, but interior plants require lots of light (but not intense, direct sunlight).
When the plant is blooming, give your potted hydrangea indoor plant periodic waterings, being cautious not to overwater. After blooming, reduce watering but never let the potting soil go completely dry. If at all feasible, use distilled water or rainwater to hydrate potted hydrangea houseplants because tap water frequently contains chlorine and other pollutants.
If the air inside is dry, use a humidifier or put the plant on a humidity tray. Particularly when flowering, hydrangea thrive in a cool environment with temperatures between 50 and 60 degrees F (10 and 16 degrees C). The environment is probably too warm if the leaves start to get brown and crunchy around the edges.
Keep heat sources and drafts away from the plant. While the plant is blooming, feed it once a week with a water-soluble fertilizer that has been diluted to half strength. After that, limit feedings to to one monthly.
It is advised to give hydrangeas a time of hibernation in the fall and winter when growing them as houseplants. Place the plant in a room that isn’t heated and is about 45 degrees Fahrenheit warmer (7 C.). To keep the plant from wilting, the potting mixture should be kept on the dry side but only lightly watered when necessary.
Do hydrangeas bloom all summer long?
Historically, hydrangeas only had one blooming season. No longer! You may now pick from a wide selection of hydrangeas that bloom all summer long. Even now, you can prune these.
With reblooming hydrangeas, you can enjoy blossoms from June until the first frost since they bloom on both new and old growth. They’ll keep blooming long after other perennials and bushes with flowers have finished. Long-lasting flowers in shades of blue, violet, pink, white, or chartreuse give any garden vibrant splashes of color.
These hydrangeas also pull off a spectacular act. The color of the hydrangea varies according to how acidic your soil is. Beautiful blue hydrangeas are quite simple to make. All you have to do is add Espoma’s Organic Soil Acidifier to your soil.
The Authentic Hydrangea of Endless Summer
A gorgeous game-changer! The first continuously flowering hydrangea was called the Original Endless Summer. It’s also simple to maintain. Its season-long color-changing blossoms will amaze you.
late spring to early fall for blooms. Depending on the soil’s pH, blooms might be blue, purple, or pink.
How should a potted hydrangea be cared for inside?
Water: While the plant is growing and blooming, keep the soil equally moist but not saturated. Roots are typically tightly packed in pots, so water frequently. Because lime will make the soil alkaline, use water without any lime. When the hydrangea is dormant in the winter and needs less water.
Room humidity is average (around 40-45 percent relative humidity). Use one of these simple methods to increase humidity for your houseplants if the air inside is dry.
Maintain a cold environment for your hydrangea plant to encourage more flowering. ideally lower than 60F/16C.
Should I remove the hydrangea’s dead flowers?
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.
Can hydrangeas be kept in pots?
Do hydrangeas thrive in containers? Given that potted hydrangeas received as gifts rarely survive longer than a few weeks, it’s a reasonable question. The good news is that they can, given the proper treatment. Growing hydrangeas in pots is a great idea because they can grow to be fairly large and have beautiful blossoms all summer long. Learn more about container-grown hydrangea plants and how to take care of hydrangea in pots by reading on.
Can you plant hydrangeas that are in pots?
A local florist gave me a lovely hydrangea plant for Mother’s Day, and they said I could plant it outside. I am aware that some plants available at this time of year are not hardy. Is there a method for me to determine whether this plant will survive outside?
A: Since I’m unsure of the specifics of what the florist sold you, I’ll take a chance and give you a broad response.
The majority of florist hydrangeas can be planted in your garden because they are “cautiously hardy” in this zone. Please keep in mind, though, that these plants were forced into bloom in preparation for this occasion. They were raised in greenhouses with controlled temperatures, humidity levels, amounts of water and light, and fertilizer feedings. The majority can be grown outside effectively once they get over the forcing and adjust to our climate.
Slowly acclimatize your plant to the outside as the weather warms up. Bring the potted plant outside gradually, and while doing so, set it in a spot with some partial sun. Water it frequently. In case the nights are chilly, bring it indoors.
After adjusting, plant it in the garden where it will remain. This should be a location with plenty of water and filtered sun, not blazing sun. Plan to water a hydrangea in dry weather, but add a layer of mulch at the base of the plant to help reduce water loss. An extra-large planting hole and well-adjusted soil are beneficial. If the plant appears to be pot-bound, gently loosen the dirt in the container as you plant.
Treat your new plant as you would an established one after planting. Keep in mind that hydrangeas shouldn’t be pruned until right after flowering. During the winter, the plant can also require protection during the below-freezing days.
I have four to five sizable hydrangea bushes, all of which were created from cuttings of a single Easter hydrangea plant that I had purchased several years earlier from a store.
I’m confident that your hydrangea planting will flourish, and every time it blooms you’ll be reminded of the giver in a good way.
A: Yesterday, I observed a powdery gray residue on the bark of a Tuscan cherry tree in our side yard that has never yielded fruit and may be removed by scraping. Do you have any advice on what it is and how to treat it when I spray it with soapy water?
Try the Green Cure product. It’s secure. It is potassium carbonate, a substance that is utilized in food. Every few weeks, spray it on to remove the mold. You won’t need to be concerned about any planted food crops in the interim. Just hours after spraying, you can pick surrounding food crops.
I haven’t noticed Green Cure in my neighborhood, but you can find out more details and costs on the Charlie’s Greenhouse Supplies website.
Take care not to damage the tree’s bark. More secure than scraping is spraying. Alternately, you might use a gentle brush or terry cloth to remove mold.
A: Spring arrived early, so instead of following your suggestion regarding the forsythia, I pruned and replanted. My fig tree is showing signs of growth after spending the winter in the basement. This year, I really hope I get some figs!
A: Although you may lose some flowers the following season, you haven’t harmed the forsythia or any flowering shrubs by transplanting them at the wrong time. The benefits of a new growth environment occasionally outweigh the need to sacrifice the blossoms, and the timing of the transplant may be best for you rather than the plant. When you can, do it!
Fig trees that spent the winter in cellars and on chilly porches are now displaying fresh growth. My fig, which was horribly mistreated this past winter, has approximately a dozen figs and has shown some leaf growth. I should possibly make Fig Newtons!
What kind of pine tree grows the quickest in the climate of northern Maine? Four or five trees would be nice to plant. When I retire in seven to ten years, I plan to live in a sizable retirement home up there.
A: Consider some Thuja Green Giants for zones 3-5. You can buy them from nearby or mail-order nurseries, and you don’t have to buy the biggest, priciest ones to have the screening you need right away for a planting that will take seven to ten years.
Without shearing, Thuja “Green Giants” develop into towering, dense columns. Set them up as a barrier screen 5 to 6 feet apart. They will grow to a width of around 5 feet if planted at this distance and in full light. They also make an excellent wind screen for the house.
They develop quickly.
In a sunny area, 3 to 4 feet each year is not unusual. Although growth could be a little slower, they also thrive in partial sun.
The fact that this evergreen is disease- and pest-resistant and that deer don’t especially enjoy them, unlike other pines and hemlocks, is one of its genuine beauty. They can withstand quite a bit of snow and ice. After they have established themselves, they won’t need a lot of additional watering or fertilization, and they thrive in typical soil.
Go for a Norway spruce if you want something that has a more pyramidal shape, like a Christmas tree—you’d receive growth of at least a foot or two a year. One of the most cold-resistant of all the spruces, they are also quite disease-resistant. They are easily accessible in any size.
Inquire about their best-selling tree if you want to purchase the necessary trees from a local Maine nursery. You’ll have a better understanding of what other local gardeners are effectively growing.
Avoid white pine because it needs direct sunlight for best growth and is susceptible to white pine blister rust. (I’m always cautious when a plant’s illness bears its name!)
Keep this in mind as you select the next dozen plants at the garden center: You have to take care of everything you plant until the frost, which is roughly five months away!
