When To Plant A Potted Hydrangea 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.

When should hydrangeas be planted?

Learning the fundamentals of how to plant hydrangeas can help you save time and money, just like with most other items in your garden. You’ll improve your chances of enjoying big, vibrant hydrangea flowers for years to come by picking the appropriate site, getting the soil just right, and planting correctly.

When should I plant hydrangeas?

The best time to grow hydrangeas is in the fall, followed by early spring. The goal is to provide the shrub lots of time to develop a strong root system before it blooms. Early in the day or late in the day are the ideal times to plant. The day’s cooler hours provide relief from heat exhaustion. Water new plants frequently until they get established.

Locations to plant hydrangeas

The first step is knowing where to grow hydrangea plants. Hydrangeas are frequently grown in beds adjacent to houses or fences. This is so because hydrangeas prefer the mild early sun to the hot afternoon sun. A protected area with sunny mornings and shaded afternoons is the ideal spot to plant hydrangeas. This is frequently found on the north or south side of a house. Avoid planting underneath trees since it could cause competition for nutrients and water. Flowers and leaves can both be destroyed by strong winds.

hydrangea-friendly soil

The soil needs to be rich in organic matter for hydrangeas to thrive. Drainage is important. Although hydrangeas prefer damp soil, they cannot stand standing water. Root rot can be brought on by wet, poorly draining soils. Your hydrangeas could pass away in a matter of weeks. Consider adding a lot of compost to your heavy soil before planting to increase the soil’s quality.

Methods for planting hydrangeas

Simply dig planting holes that are 2 feet wider than the root ball for planting hydrangeas. So that your plant lies level with or just higher than the surrounding soil, match the depth of the hole to the size of the root ball. You can improve water drainage away from the plant’s base by making a small mound.

The best way to grow hydrangeas

Simple propagation methods can multiply a single hydrangea into several more. The optimal time to layer bigleaf and panicle hydrangeas is in the early to mid-summer. You only need to:

  • Close to your hydrangea plant, make a tiny trench.
  • Bend a branch such that the middle of the branch meets the earth in the trench (six to 12 inches of branch should extend past the trench).
  • Where the branch meets the trench soil, make scuff marks on the bark.
  • After the trench is filled, cover it with a paver, brick, or stone.
  • The branch can be transplanted to a different area once it has established its own root system over time.

Hydrangeas with smooth or oakleaf leaves produce new growth from underground stems. Simply separate the baby plant from the main plant by digging it up. After then, it can be moved to a new spot.

Can hydrangeas in pots endure the winter?

Hydrangeas in potsWinter Care 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.

Can you grow hydrangeas in pots?

Our greenhouse is loaded with lovely potted Hydrangea plants before Easter and Mother’s Day. These are great gifts, but many people worry if it’s feasible to store them and plant them in the landscape later because they are produced in a greenhouse and are in flower months before their normal blooming season when grown outdoors. Here are a few success suggestions:

  • On Cape Cod, the majority of hydrangeas offered as gift plants are hardy. They will develop flower buds in August, just as regular Hydrangea macrophylla, and those buds will bloom the following summer. If wintertime temperatures fall below 10 degrees, these buds are susceptible to damage from the cold. As a result, these will have less blossoming in the summer following a cold winter, just like all of our pink and blue hydrangeas.
  • Hydrangea plants in pots dry out rapidly. The hardest part of keeping them indoors in April and May is doing this. The best course of action is to move your greenhouse Hydrangea as soon as possible into a little bigger container. Make sure the pot you use has a drainage hole and is about an inch larger on all sides. Fill in the gaps with fresh potting soil, but don’t pack it in too tightly. Squeezing the air out of the openings will prevent the roots from growing and will also prevent the water from flowing.
  • After repotting, keep your hydrangea in a sunny area, but avoid placing it at the window with the most sunlight. The ideal window is one that faces east. Additionally, plants will flourish if they are placed close to but not directly in a southern or western window.
  • If the soil on your hydrangea starts to feel dry, water it right away to prevent drooping. Keeping the pot submerged in water for more than an hour could result in the roots rotting.
  • Put your hydrangea outside in part shade at the end of May, then bring it inside at night for a week. Place your Hydrangea after that week in a location that will provide morning sun and afternoon shade. Don’t let its current tiny size deceive you; most Hydrangea shrubs grow at least four feet high and wide.

In our naturally acidic soils, red-toned Hydrangea blossoms will turn a dark purple or blue. The blossoms will continue to be red or pink if the soil is still alkaline.

Even though these hydrangeas were produced in a greenhouse, they should develop and bloom the following year provided the correct conditions during the winter.

Long-term, hydrangeas are not the best indoor plants. However, if you reside in a region where winter lows often drop below 5 degrees, you can plant these in pots and overwinter them in a garage or another warm location where temps won’t fall much below 30 degrees. Don’t worry, they will start to leaf out in the garage in March. Just remember to keep the soil moist but not soggy, and move the plants outside once the risk of frost has passed. Ideally, they should bloom in late June or early July. When you set the pot outside for the summer, fertilize with an equal mixture of Osmocote and Holly-tone or Flower-tone (one tablespoon each per pot).

After a potted hydrangea blooms, what should you do with it?

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.

Where to plant hydrangeas:

  • A location with morning sun and afternoon shade is ideal. They’ll take more sun if you reside further north (possibly full sun all day).
  • Think about the mature size and give it lots of room to expand.
  • Pick a location with great drainage. If necessary, add compost to the soil.
  • Plants won’t thrive if they are planted too close to a tree because of root competition and a lack of sunshine.
  • Planting should not be done in open locations where strong winds could snap stems.

How to plant hydrangeas:

  • By amending your soil with up to 15% organic matter and an all-purpose slow-release fertilizer, you may give your plant a good start (use half of what is recommended).
  • Plant a little higher than you did while you were in the nursery container.
  • In order to give the roots plenty of freedom to expand, the planting hole should be two to three times broader than the root ball.
  • Before planting, gently untie the roots from their pots.
  • Add the modified dirt back in and thoroughly water it.
  • Planting in groups requires a minimum distance of 3 feet (more, if planting larger varieties).

Planting hydrangeas in pots:

  • Put potting soil in a bag rather than garden dirt.
  • Slow-release fertilizer should be added.
  • For watering, leave 1 to 2 inches between the soil’s top and the pot’s rim.
  • Make sure the pot includes space for the plant to grow and drainage holes.

Can I now start a hydrangea?

While containerized plants are readily available year-round, the best selection of hydrangeas in garden centers begins to appear in the middle of the summer when they are in bloom.

They are typically offered in 3 liter pots that are at least 30 cm tall in garden centers. Young cuttings of mail-order plants may be offered in 9 cm or 1 liter containers.

When to plant

As soon as you buy your shrubby hydrangea, plant it. Spring or autumn are the ideal seasons for planting. As long as the soil is not frozen, too wet, or overly dry in the summer, containerized plants can be planted all year (but you can water them well if you really want to plant them then).

Soil preparation

If cultivars are grown in acidic soil, their blue flowers will maintain that color (pH 4.5-5). See our guides on soil acidity and how to acidify your soil for additional details.

How should a potted hydrangea be cared for?

If you’ve ever received a hydrangea in a foil-wrapped pot, you likely loved it for a few of weeks before seeing it sadly wilt. You might conclude from it that hydrangeas are poor container plants.

Most hydrangeas that are given in pots as gifts do poorly because they are kept indoors for too long. Others perish because they were grown in a greenhouse and are not cold hardy in your region of the country, even if they are planted outside.

However, hydrangeas can make wonderful potted plants if you choose wisely. What you should know is as follows.

Potted Hydrangea

You can utilize hydrangeas in containers in your garden on stands, decks, or patios. This plant looks classy perched atop an antique column.

  • Choose a location for the hydrangeas first. You may move them around, which is one of the benefits of growing them in pots. This also makes it simpler to provide hydrangeas with the ideal growing circumstances because many of them like morning sun and afternoon shade. Additionally, you can arrange them to beautify a patio or other area for a celebration or special event.
  • If your pots won’t stay in the same spot all the time, search for containers with wheels on the bottom or think about durable, rolling plant stands. Don’t forget that after adding dirt and plants, containers can become rather heavy, and soaking them can make them even heavier.
  • For your hydrangea, pick a large container with a diameter of at least 18 to 20 inches. The plant commonly wilts in small pots like the one your gift hydrangea arrived in since they typically dry out too quickly. Drill drainage holes into the bottom of your container if there aren’t any already. Rotting can result from water that accumulates around the roots.
  • Next, pick a variety that is advised for your area. (This is a general guideline for growing any plant well.) To choose the best types for your yard, read plant tags or conduct online study. Some hydrangea varieties can grow in USDA zones 3 and 9, while the majority are hardy in zones 4 to 8.
  • Although using miniature hydrangeas in pots isn’t required, you might wish to if you have a small yard. Not only do hydrangeas grow tall, but they also become bushy. If not, prepare to prune your plants as they develop. Be careful when conducting your research; see if your variety blooms on new or old wood. You’ll lose the flowers for the following year if you prune at the incorrect time of year.
  • Use high-quality potting soil that contains organic materials rather than regular garden soil. If you want the hydrangea to continue growing, don’t plant it higher or deeper than it was in the pot it came in. Make sure there is space below the pot’s rim so you can water.
  • To get rid of air pockets, gently compact the dirt close to the roots.
  • Water your hydrangea well whenever the top inch or so of the potting soil feels dry. But being underwater is preferable to being overwatered. When they are thirsty, hydrangeas may wilt to let you know. However, this can stress them out, so check them every other day or so. You’ll eventually get a sense for how frequently to water. In times of drought or extreme heat, you might need to increase your watering.
  • Although hydrangeas don’t require a lot of fertilizer, you can feed your plants once or twice a year with a commercially available composted manure, a 10-10-10 granular fertilizer, or a slow-release balanced fertilizer. If you reside in a warm environment, wait until after July or August to fertilize. Gardeners in the north can get away with applying fertilizer just once, in June or July. Feeding hydrangeas later, when they should be starting to go dormant for the winter, promotes fragile, fresh growth.
  • If your plant already appears to be ill or unhealthy, don’t fertilize it—you’ll just increase its stress. Try to solve the issue instead.
