What month is best to plant hydrangeas?

Planting hydrangeas in the Southeast is best done in the fall due to less harsh conditions and the absence of leaves. However, planting in early spring after the last frost can be challenging due to the tough growing conditions of the season. Hydrangeas need morning sun and afternoon shade for optimal blooming, but they will not tolerate hot afternoon sun. To ensure the best planting location, watch your landscape for a few days to ensure the area receives shade during the hottest part of the day.

It is essential to keep hydrangeas well-watered throughout the season, as they need to endure the toughest growing conditions. Overall, planting hydrangeas in the fall is a wise decision for optimal growth and health.

Do hydrangeas grow best in 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.

What are the most hardy hydrangeas?

Hydrangea paniculata is a hardy plant that forms buds in early summer just before mid-summer blooms. Its flowers, which appear in July or August, make great cut flowers or can be easily dried for arrangements. Growing this plant is easy, as it can be planted in full sun and adaptable to a wide range of soils. It has no serious pests and can be cut back hard in early spring for extra large flowers.

Limelight Hydrangea is the best-looking plant in the author’s garden. Initially seen in the Netherlands, the plant was initially described as cool with soft green flowers but turned out to be a unique and beautiful plant. Gardeners from Orlando to Manitoba have expressed their admiration for this plant, with a landscaper from Chicago using it in every design he creates.

Limelight thrives in various conditions, including sun, shade, sand, or clay soils, and is a winner in both North and South regions. The plant is a unique and beautiful addition to any garden, making it a valuable addition to any landscape.

Do you remove dead flowers from hydrangeas?

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.

When should I plant hydrangeas in Colorado?

Hydrangea shrubs are best planted in fall and spring, with summer being not recommended. However, they should be watered regularly and avoided in full sun to prevent stunting their roots. Transplant hydrangeas when dormant and avoid them during bloom, as they are weakest and may wilt large blossoms. Choose a location that favors the variety you choose, as there are many different varieties available.

Certified organic gardener and co-founder of Garden Girls, Jen McDonald, advises selecting a location that favors the variety you choose, as it can significantly impact the growth and foliage of the plant.

How do you keep hydrangeas alive in Colorado?

Hydrangeas thrive in various sun and shade conditions, but they require moist, well-drained soils rich in organic matter. Colorado soils can benefit from peat moss, compost, and mulch to retain moisture and acidify the soil. Watering is essential for the first year or two until well established, and once a month through winter to prevent winter kill. Hydrangeas respond to soil chemistry, with acidic soils producing blue flowers and alkaline soils producing pink flowers.

Soil amendments like peat moss and other treatments can control color, but not all varieties respond to these treatments. Winter hardiness for hydrangeas is affected by flower buds being more tender than leaf buds, which can be damaged by hard frost. The plants will leaf out and grow well, but no flowers will be produced.

Can hydrangeas survive in Colorado?

Hydrangeas, such as oakleaf and panicle, have large lobed leaves and cone-shaped clusters of white or greenish flowers. They can grow in a range of sun and shade conditions, but need enough sun for blooming. They thrive in moist, well-drained soils rich in organic matter, which can be enhanced with peat moss, compost, and mulch. After planting, check frequently and water as needed, especially for the first year or two until well established. Hydrangeas respond to soil chemistry, with acidic soils producing blue flowers and alkaline soils producing pink flowers in many varieties.

Soil amendments like peat moss and other treatments can control color, but not all varieties respond to these treatments. City Floral’s experts can provide color recommendations for different varieties. Watering is essential for the first year or two until well established and once a month through winter to prevent winter kill.

Should I cover hydrangeas for freeze?

Hydrangeas need protection depending on the winter temperature drop. If the air temperature doesn’t drop below 0 degrees (zone 7) there is no need for winter protection. In colder climates, wrap or cover marginally hardy hydrangeas, especially those that bloom on old wood, like mop head/big leaf hydrangeas. Newer varieties bloom on both new and old wood. Hardier hydrangeas like paniculata and arborescens don’t need extra winter protection, but extreme cold can cause die-back of their branches.

If a colder than normal winter is predicted, consider covering plants with burlap or a mulch mountain. There’s still time to plant hydrangeas, as they can grow in Zone 4 and warmer zones (5 to 9) and fall is the best time for planting. Follow the steps above, especially watering and mulching.

How close to the house should I plant a hydrangea?

Two feet of spacing between hydrangeas is likely too close, especially near your house, which can cause them to become crowded. It is best to have shrubs have a couple feet of clearance near the house walls. The type of hydrangea you bought can determine the spacing, with some growing up to 10 feet and others 5-6 feet apart. Endless Summer, a newer variety, is planted about 3-5 feet apart and can bloom on both new and old wood. Older types bloom only on old wood and may bloom the following summer in harsh winters.

If you have any plant tags, check the Lowes website for typical plant tags. To increase the distance, lift some hydrangeas and group them in groups of 3 or five. Hydrangeas have shallow roots, making them easy to transplant.

Where is the best place to plant a hydrangea?

Hydrangeas flourish in warm morning sunlight but require shadier conditions in the afternoon, making them an excellent choice for planting in areas with a combination of sunny mornings and shadier afternoons, which are often found on the north or south side of a residence.
