How Should Hydrangeas In A Pot Be Maintained?

Potted hydrangeas are a great container plant option for those who only have areas where they can be placed, such as porches, driveways, balconies, sidewalks, and decks. They have long-lasting blooms with minimal effort, making them an excellent choice for front porches, balconies, and other outdoor spaces.

To properly care for potted hydrangeas, follow these 15 essential tips:

1. Choose the right pot: The size and type of container will depend on whether you plan to treat your hydrangea as an annual and keep it in the pot for just one growing season or as a perennial. Hydrangeas need a large pot due to their quick root system.

2. Plant correctly: For hydrangeas to flourish, place the container in a location receiving at least part sun (4-6 hours) or full sun (+6 hours) per day. If you live in a cold climate, use high-quality potting soil with organic matter, not ordinary garden soil. Plant the hydrangea at the same level as its original pot.

3. Regular watering: Hydrangeas need regular watering, a couple of times a week, as their leaves may start to droop. Use high-quality potting soil with slow-release fertilizer and compost for additional support.

4. Plant at the same level as its original pot: Choose a small, compact hydrangea variety and place it in a location where it gets at least four hours of sun each day.

In summary, potted hydrangeas are a versatile and beautiful plant option that can be easily maintained with proper care and attention.

How long can a hydrangea stay in a pot?

The size of the container is crucial for hydrangea growth, as it allows the roots to grow. A large pot with a diameter of at least 24 inches is suitable for small to midsized hydrangeas for several years. A rolling plant caddy can be used for greater mobility. If you plan to grow a potted hydrangea as a perennial and overwinter it outdoors, choose a variety that is two zones hardier than yours. For example, a hydrangea hardy down to zone 3 will have the best chance of survival in zone 5.

Additionally, choose a hydrangea shrub that is the right size for the space you plan to display it in. Compact or midsize varieties don’t require much pruning or frequent repotted. For permanent plantings, the mature size of the hydrangea should be your guide. If using a hydrangea as an annual, choose a plant that is already close to the size that suits your needs.

How do you keep potted hydrangeas blooming?

Bigleaf hydrangea, commonly sold in garden centers and floral shops, are known for their large blue or pink flowers. They thrive in bright, indirect light and cool temperatures, and should be kept moist and watered as the soil becomes dry. However, they require complex steps to bloom indoors, and the cultivars used for florist plants are not reliably winter hardy in Iowa. If they survive winter, they will not reliably flower, so they should be discarded once the flowers fade.

Should I cut off dead hydrangea blooms?

Deadheading is a technique employed to maintain the color of the “Endless Summer” hydrangea, enabling it to continue blooming throughout the summer and fall seasons.

Do coffee grounds help hydrangeas bloom?

Hydrangeas’ color is influenced by the acidity of their soil. The more acidic the soil, the more blue the blooms. To achieve the best blue hydrangea blooms, add coffee grounds to the soil. The pH level of the soil is crucial for hydrangeas to bloom. Higher acidity results in bluer blooms, while more alkaline soil produces pinkish flowers. Some hydrangea names, like Nikko Blue and Nantucket Blue, are influenced by their soil’s pH level. French hydrangeas are known for their globe-like blooms, which can be manipulated to suit color preferences.

To ensure blue blooms, ensure the soil is acidic. Fertilizers can help, but leftover coffee grounds can be just as effective and cost-effective. French hydrangeas are prized for their globe-like blooms, which can be manipulated to suit individual preferences.

How do you keep outdoor potted hydrangeas alive?

Hydrangeas, a popular shrub, can thrive in containers as well as gardens. To ensure proper growth, it is essential to monitor the soil’s moisture levels in your potted hydrangea. Potted hydrangeas require at least part sun (4-6 hours) or full sun (+6 hours) per day, with some shade in the afternoon for warmer regions. Pots and containers allow for mobility, allowing you to adjust the location throughout the season.

When choosing a container, consider choosing a weatherproof material that can withstand the outdoor elements, as they cannot be grown indoors in winter. This material should not break or flake apart from exposure to freeze-thaw cycles.

In summary, hydrangeas are a versatile and beautiful plant that can thrive in both indoor and outdoor spaces. To ensure the best growth, it is crucial to monitor soil moisture levels and choose a container that can withstand the elements.

Do hydrangeas like sun or shade?

Hydrangeas, commonly known as hydrangeas, prefer partial sun locations, receiving sun in the morning and shade in the afternoon. The Endless Summer® Hydrangea series, such as BloomStruck®, Endless Summer®, Blushing Bride®, and Twist-n-Shout®, prefer part shade. Smooth hydrangeas like the Annabelle Hydrangea also require some shade from the afternoon sun. Bigleaf hydrangeas, also known as hydrangea macrophylla, prefer some shade, especially during the afternoon. For best flowering, big leaf hydrangeas like Nikko Blue and Glowing Embers should get some sun.

Planting hydrangeas in a spot with good drainage, morning sun, and afternoon shade is essential. Most hydrangeas bloom in spring and summer, and can reach heights of 15 feet or higher. They can be grown in pots to decorate patios, apartment balconies, or as a hedge or privacy screen.

Panicle hydrangeas like Fire Light®, Limelight, Pinky Winky®, Strawberry Sundae®, and Vanilla Strawberry® can thrive in full sun. The new reblooming dwarf series, Let’s Dance®, and dwarf big leaf series, Cityline®, grow best in full or part sun. Newer smooth hydrangea varieties, Incrediball®, and Invincibelle® Ruby, are also recommended for full or part sun.

Will potted hydrangeas bloom all summer?

Potted hydrangeas can be grown in pots, as they can grow large and produce stunning blossoms all summer long. However, they require proper care and sunlight. Store-bought potted hydrangeas often languish due to their small size. To ensure proper growth, place them in a spot with full sun in the morning and shade in the afternoon. Move them to a larger pot with drainage holes and leave about three inches of space between the potting mix and the rim. Water the pot by filling it to the brim with water, letting it drain, and repeating.

Successioning hydrangeas in pots is relatively easy. Choose a dwarf variety from the beginning or prune your full-sized hydrangea back. It’s important to check the variety before pruning to avoid accidentally pruning away all potential summer flowers.

In winter, grow hydrangeas in pots in a cool but not cold garage or basement. Water them moderately and bring them back outside when spring temperatures rise.

Is Miracle Grow good for hydrangeas?

Water-soluble fertilizers, such as MiracleGro®, can be used to improve the bloom color of hydrangeas, particularly for new plantings or those recovering from stress. This high phosphorous level is not ideal for a sustained “blue” hydrangea fertilization program, but it can be beneficial for spot use and reviving stressed plants. Bloom color manipulation is only achievable with H. macrophylla and H. serrata, and is most associated with plants with mophead bloom form.

The primary soil component for making blue blossoms is the presence of aluminum in the soil, and pH is closely relevant. Bloom color can be substantially altered depending on soil pH, but should not be overdone. Cultivars with pale bloom pigment can be adjusted between pink and blue, while medium to dark blue varieties like Mathilda Gutges can be decent fuchsia pinks but more brilliant in their normal purple-blue hues via aluminum sulfate.

How do you perk up potted hydrangeas?

Prior to planting the hydrangea in a new receptacle, it is advisable to stimulate the roots in order to facilitate recuperation.

Are you supposed to cut back hydrangeas?

To maintain a tidier look in your garden, consider pruning dried flower heads in spring. If you live in areas with heavy snow or prefer a tidier look, prune them in late fall to early winter. Reblooming hydrangeas, which bloom exclusively on new wood, should be pruned the same way as those that bloom on old wood. This means only pruning out a few dead branches in spring once the plant starts to leaf out.

Should I water my potted hydrangea every day?

Potted hydrangeas require frequent watering due to their fast drying process. Check the soil daily and water the entire plant until it drips out of drainage holes. They may need watering twice a day during hot summers and twice a day with more sun exposure. Hydrangeas do not tolerate extreme temperatures, so choose a protected spot with constant winter temperatures. A north- or east-facing site with consistent winter temperatures is best for hydrangeas, as they don’t receive too much winter sun. They are tolerant of moderate to high humidity but not dry, hot climates.
