When Should Hydrangeas Be Planted In Northern California?

In California, hydrangeas should be planted during the fall when the shrub has six weeks of mild weather. The ideal time to plant hydrangeas depends on the gardening zone and can vary depending on the region. In general, the best time to plant hydrangeas is in spring or fall. If planting a container-grown hydrangea, dig a hole twice the width of the shrub’s root ball before planting.

There are several types of hydrangeas, including Mophead (hydrangea macrophylla), Lacecap (hydrangea macrophylla), Oakleaf (hydrangea quercifolia), and Hydrangea paniculata (hydrangea paniculata). These plants require well-amended soil and can be planted in areas with winter freezing and snow. In warmer climates, hydrangeas can grow in a range of exposures from full sun to full shade, with dappled shade being ideal.

The timing of planting depends on when dormancy starts, with northern lower zones 3-5 having a dormancy (fall) season of 3-4 weeks. Spring and Fall are ideal times to plant hydrangeas, but avoid planting them in summer when temperatures are above 85 degrees. Hydrangeas prefer well-draining soil and can be grown in a variety of locations, including full sun to full shade.

In summary, hydrangeas should be planted during the fall when they have six weeks of mild weather and are well-adapted to their local climate.

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.

Do hydrangeas lose their leaves in California?

Hydrangeas are deciduous shrubs that lose their leaves in winter, with some dying back. However, the oak leaf hydrangea has spectacular fall color in cold years. Pruning is crucial for ensuring a mass of flowers, as flower buds form in the summer before blooming. Some gardeners do not prune their shrubs, but it is safe to prune up to 50% of the stem length if the plant is too gangly in dormancy. Pruning out dead limbs and cleaning up the plant is essential for a tidy appearance.

When to prune hydrangeas in the northern California zone?

Pruning hydrangeas is not a mandatory annual event, but rather an opportunity to tidy up the plant. If there are dead or spindly stems, cut them down to the ground. Mature hydrangeas don’t respond well to severe pruning, so consider moving the plant to a location where it can grow to its desired size. Pruning older hydrangeas can help prevent them from becoming misshapen or spindly. Removing a quarter to a third of the oldest canes each year, cutting each down to the base, will cause healthy, vigorous new growth to emerge. Over time, a lush, healthy shrub will emerge. In Northern California, this usually occurs in December.

Do hydrangeas grow well in northern California?

Hydrangeas are a popular ornamental plant in California due to their ability to thrive in a variety of conditions and their distinctive, colorful clusters of flowers. They are available in a range of varieties and require minimal care. They flourish in morning sunlight and afternoon shade, with some varieties exhibiting blooming behavior in partial shade, particularly in the case of big leaf hydrangeas. It is of the utmost importance to ensure that the planting and pruning of these plants is conducted in an appropriate manner in order to facilitate optimal growth.

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.

How to grow hydrangeas in California?

Hydrangeas thrive in morning sun, but closer to the Southern California coast can handle more sun. If your house is inland, a north-facing or east-facing spot is best to protect them from too much sunlight. Hydrangeas won’t do well in heavy shade, as the blooms will struggle. They can also thrive in containers, but need extra care to avoid water evaporation. Soil should be moist, not sludgy, and if dry, add more water. Fertilize them twice in a growing season.

Hydrangeas are water-loving plants, so it’s essential to provide suitable irrigation and avoid overwatering. Keep the ground cool using mulch and avoid overwatering, as water is the key to keeping them blooming happily.

When to plant hydrangeas near San Diego, CA?

Purchase a hydrangea during its bloom to see its growth and avoid frost danger. Plant in spring, early summer, or fall, but avoid early spring when frosts are still present. Hydrangeas bloom from early spring through summer and prefer filtered to partial sun, with full sun tolerated in coastal areas. In hotter inland areas, they thrive with morning sun and afternoon shade. Ensure good drainage and dig a hole three times the size of the container.

Mix up to 50 native soil and acidic amendment, like camellia and azalea mix. Plant in the hole with the root ball slightly above ground level, creating a 2-inch-high rim of soil to prevent water runoff.

Do hydrangeas need to be cut back for winter?

Hydrangea paniculata, also known as panicle hydrangea, is a plant with conical-shaped flower heads that can be pruned back to just above a fat bud in fall, late winter, or spring. These plants produce buds in late summer to early fall, which will form next year’s flowers. To maintain winter interest in your landscape, it is recommended to wait until late winter or spring. Popular panicle hydrangeas include Quick Fire®, Limelight, and First Editions® Berry White®.

Are hydrangeas best in pots or ground?

Pot-grown hydrangeas can be planted in various locations, including open ground or containers using John Innes compost. Large pots are recommended for long-lasting growth. In open ground, prepare the soil by adding garden compost or organic manure, and 6X Natural Fibrous Fertilizer to boost humus content. Add Vitax Hydrangea Feed or compost when planting for essential nutrients for healthy growth and beautiful blooms. Hydrangeas thrive on most soils and heavy clay, making them ideal for new-build gardens and wet, compacted soils.

Regularly adding organic compost or manure helps hold on to moisture, while mulching the ground around the plants with compost or bark early in the season helps retain moisture. This is done after their annual application of Vitax Hydrangea Feed.

What is the season for hydrangeas?

The blooming season of the hydrangea is subject to influence from a number of factors, including the specific type, cultivar, and planting zone. New growth hydrangeas typically bloom in early summer, followed by subsequent blooms in spring, summer, and fall. In regions with high temperatures, the blooming period may be interrupted during the summer months, but the plants will resume blooming in the autumn.

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.
