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 in indoor pots be planted outside?
“For Mother’s Day, my daughter handed me a lovely hydrangea. It has done so wonderfully that I’m curious if I should plant it outside or keep it within as a houseplant.”
Hydrangeas with foil encircling the pot, whether they were a gift or something you bought yourself, frequently differ from those bought at a nursery. The foil-wrapped hydrangea is often grown for a single, grand performance. The plant has been specifically fed to produce a lot of huge blooms quickly, frequently at the price of the plant’s long-term health.
The hydrangeas selected for this project are exclusively grown in greenhouses and might not be winter hardy where they are purchased.
If your locale isn’t warm enough to cultivate hydrangeas outdoors, you might wonder if you can grow them indoors as a houseplant.
A. There are a variety of reasons why growing hydrangeas inside in a home environment is not particularly successful. When hydrangeas may experience a period of dormancy brought on by chilly weather, they thrive. Hydrangeas rarely blossom indoors, attract insects, and lose their leaves unless they are in a greenhouse. They frequently dry out too rapidly and wilt, which makes them weaker.
However, some gift/florist-type hydrangeas may be grown extremely well in the landscape, as you can see from the images below.
Although growing hydrangeas indoors is not the optimal answer, it is conceivable if one lives in an apartment or in an area where they cannot survive:
1) Put the hydrangea in the coolest part of your house; ideally, an unheated room.
2) Position it close to a window so that it receives the most light possible.
The third and most crucial tip is to not overwater the plant by letting it sit in water or by watering it too frequently. It’s preferable to keep it dry during the winter, but it shouldn’t ever get too dry that it wilts.
Whenever possible, it is ideal to plant the potted hydrangea outside. It should only be planted outside in the early to mid-summer because it needs time to get used to the weather before winter.
In conclusion, unless it may be planted in the garden, foil-wrapped hydrangeas are best employed as a temporary plant in a person’s home.
How are indoor hydrangeas planted outside?
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!
HEADING*h2# Do indoor and outdoor hydrangeas look alike?
“Indoor hydrangeas,” also referred to as “gift hydrangeas,” began to appear on the shelves of warehouse clubs, box stores, grocery stores, and florists around Easter and continued through Mother’s Day. They literally fly off the shelf because they are so stunning. They also frequently lack tags, labels, and any other kind of information about how to care for them or what to deal with them once they have finished blooming. Even though we don’t sell this particular variety of hydrangea on our website, we’re pleased to share our knowledge and offer some advice if you happen to be the lucky recipient of one – whether as a gift from a friend or as a gift to yourself.
This word is mostly used to denote that this plant should be kept indoors during its flowering period. Hydrangea macrophylla, often known as bigleaf hydrangea, florist hydrangea, or hortensia, is the species most commonly found in indoor settings. Plant breeders create “indoor hydrangeas” expressly for this market for gift plants with an eye on their appropriateness for greenhouse production, premium, disease-resistant foliage, and of course, distinctive and eye-catching blossoms. Because these hydrangeas are meant to be enjoyed indoors, their outdoor or long-term performance is rarely, if ever, taken into account.
Place your indoor hydrangea in a cool, bright area that is out of direct sunlight and away from drafts of hot or cold air for the flowers to stay the longest. Feel the soil surface when you get it home; it should feel relatively damp. It might need some water if it doesn’t and/or if the pot feels particularly light. But before you water it, carefully examine the container: Gift hydrangeas are frequently placed in non-draining attractive outer containers or wrapped with a foil wrapping covering the bottom. In these situations, you should get rid of anything that can collect water in it, water your hydrangea, and then, if you’d want, put it in the ornamental element when it has properly drained.
To ensure that your hydrangea blooms for the longest amount of time, it is crucial to keep it cool and well-watered but never wet.
The spent blooms can either be kept on when the flower color dwindles or they can be removed, depending on your preference. Undoubtedly, some people age more gracefully than others. However, once all of your plant’s blossoms have opened and faded, the show is over; especially if you’re trying to grow it inside, it won’t produce any more flowers that season.
These are not houseplants, despite the fact that they are advertised as “indoor hydrangeas.” In other words, there are very few opportunities to successfully cultivate the hydrangea inside in a conventional household setting. The hydrangea is very unlikely to establish flower buds again given the light and temperature conditions of a home, and the low humidity and poor air circulation can lead to pest or disease outbreaks.
If the weather permits, you might try planting the hydrangea outside, but it’s crucial to keep in mind that the majority of indoor/gift hydrangeas weren’t created with outdoor performance in mind. Many of them are not very resistant to cold, and they will perish in winter in climates colder than USDA zones 7 or 8. It’s obviously preferable to try to grow a hydrangea outside if you have the space, but if you do plant it in the ground, it’s crucial to have realistic expectations for how it will behave. Plant it in a protected area and cover the roots with a thick 2-3″ layer of mulch for optimal results.
In particular, around Mother’s Day.
In addition to their aesthetic appeal in terms of flowers and leaves, outdoor hydrangeas are chosen for their suitability for nursery production and long-term outdoor performance in the outdoor/landscape/garden market. It is probably reasonable to assume that your plant is designed to be put outdoors and will thrive there for a long time if it came with instructions for outdoor planting. In this situation, enjoying it indoors for a few weeks while taking care of it as previously mentioned is absolutely okay.
How can you keep hydrangeas in pots alive outside?
Since a small container on the kitchen table is not the optimal location, store-bought potted hydrangeas frequently wither away. Hydrangeas prefer a lot of water and sunlight. While the water can be obtained by moving it to a larger container that doesn’t dry out as quickly, the sun can be obtained indoors by placing it in a south-facing window. Garden hydrangeas prefer full sun, but this rapidly dries out the soil in pots. To prevent drying out, plant your hydrangeas in a location that receives full sun in the morning and some afternoon shade.
Replace the pot your hydrangea is in with one that is several inches (8 cm) bigger in diameter and includes drainage holes. Leave a gap of about three inches (8 cm) between the potting mix’s surface and the pot’s rim. Fill the pot to the full with water, let it drain, and then repeat to water your container-grown hydrangea plants.
The subsequent care of hydrangea containers is also rather simple. Hydrangeas have the potential to grow to be enormous. You have two options: you either cut your full-sized hydrangea back or start out with a dwarf type. Just make sure you have the right variety before you prune. On both young and old growth, hydrangeas produce flowers. Avoid mistakenly removing all of the summer’s potential blossoms with pruning.
Hydrangeas in containers need some care over the winter. Place your container in a garage or basement that is cool but not frigid. Bring it back outside when spring temps rise and moderately water it.
