In Which Month Do Hydrangeas Bloom Perpetual Summer?

Endless Summer hydrangeas are a unique and hardy variety of Hydrangea macrophylla that can re-bloom throughout the summer. They bloom in late spring and then put on a second round of flowers in mid-late summer. To grow an Endless Summer hydrangea, amend the soil with organic matter before planting, select a location with full morning sun and dappled shade in the afternoon, and spread a layer of organic mulch around the plant without touching its base.

Fall or early spring are the best times to plant Endless Summer hydrangeas, as they need time to establish their roots in the soil before their blooming season begins. These deciduous shrubs are known to bloom 10 to 12 weeks longer than average Hydrangea macrophylla plants and show well in colder climates. Endless Summer hydrangeas bloom from May through October, depending on the location.

Endless Summer® Hydrangeas are known to bloom 10 to 12 weeks longer than average Hydrangea macrophylla plants and show well in colder climates. They grow quickly, maturing at about 4 feet tall and wide, and enjoy partial shade to full sun. They can bloom on both old and new growth from spring through summer.

To care for Endless Summer hydrangeas, follow these care requirements: amend the soil with organic matter before planting, select a location with full morning sun and dappled shade in the afternoon, and spread a layer of organic mulch around the plant without touching its base.

Blooming time for Endless Summer hydrangeas depends on the climate, but they should bloom around the middle of July. Pruning is not necessary, as they bloom on previous years’ growth and the new season’s growth.

Why isn’t my endless summer hydrangea blooming?

The main reasons why hydrangeas don’t bloom endlessly are sun exposure, over-watering, and over-fertilizing. Endless Summer® hydrangeas prefer morning sun and afternoon dappled shade, while full sun may be too hot for blooms. Over-watering and over-fertilizing can inhibit bloom production. Hydrangeas prefer moist, but not wet soil, and one application of fertilizer in spring or early summer. Pruning hydrangeas back after an early frost may take some time for new growth to develop and produce blooms. To ensure your hydrangeas bloom endlessly, follow these tips and follow our blog on making your hydrangea bloom.

How do you winterize endless summer hydrangeas?

To prepare the Endless Summer Hydrangea for winter, stop fertilizer applications after August 15th, keep soil moist until the ground freezes, and cover the plant with organic mulch. This should be done when the plant is fully dormant, around November 30th. In spring, uncover the plant when the ground is no longer frozen, and allow it to grow from the base and any old branches that survived winter. Be patient, as growth will take time until the heat of late spring stimulates it.

Once growth is visible, prune back old branches to a finger width above the new green growth. The plant should bloom around the middle of July, depending on your climate. Endless Summer Hydrangea is forgiving and will not suffer if left unpruned or pruned at the wrong time. It will bloom on both old and new wood, and deadheading spent flowers will encourage this. Cutting the blooms for drying or fresh cutting in vases is also beneficial, as it encourages the plant to produce more blossoms. Spring is the best time to prune.

What month do you cut hydrangeas back?

Hydrangea paniculata, also known as panicle hydrangea, is a plant with conical-shaped flower heads that provide winter interest. It is best to prune back stems to just above a fat bud, called a heading cut, in fall, late winter, or spring. Quick Fire®, Limelight, and First Editions® Berry White® are plants that produce buds in late summer to early fall, so they should be pruned after they finish blooming and before August.

How often should I put coffee grounds on hydrangeas?

To change the color of hydrangeas, start by adding coffee grounds to the soil around them in late fall. Work the grounds into the soil to eliminate any off-putting smell and do this two to three times per year. It will take time to turn hydrangeas blue, especially for new baby hydrangeas that may not bloom for a couple of years. Start adding coffee grounds months before the blooming season begins, ideally in late fall. Repeat the process with your regular fertilizing schedule. With a little caffeine and patience, your hydrangeas should reward your efforts with bold blue globes in the spring.

How many times do endless summer hydrangeas bloom?

Endless Summer hydrangea macrophylla require minimal pruning to maintain their beauty and re-bloom throughout the summer. They bloom on both the current and previous years’ growth, allowing for re-blooming throughout the season. Over-pruning can remove potential blooms, so it’s important not to over-prune. If living in freezing temperatures, it’s crucial to protect the plants from freezing temperatures by protecting the flower buds on the old wood.

Do not prune or cut back shrubs after August 1st, as this provides winter interest and prevents removing buds that will become flowers in the spring and summer. Insulate the plants with leaves, wood mulch, or straw, and mound them at least 12″ high to protect the flower buds that will bloom early next year. In the spring, wait until frost has passed before uncovering the mulch to ensure beautiful blooms from old and new wood. If your hydrangeas are planted in a container, bring the entire container into your garage or cool basement for winter months and follow the same steps as garden-planted hydrangeas.

Should I cut off brown hydrangea blooms?

While deadheading is beneficial for plants, it should be discontinued in mid to late fall to allow the blooms to remain intact throughout the winter season.

How to make endless summer bloom?

To achieve the promised endless blooms of hydrangeas, maintain soil moisture and fertilize once in spring or early summer. Overwatering and over-fertilization can decrease bloom production.

Can you use Miracle Grow on endless summer 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.

Do endless summer hydrangeas like sun or shade?

Endless Summer hydrangeas thrive in areas with morning sun and dappled afternoon shade, with the amount of sun varying based on the zone. They prefer dry soil, watering the ground underneath the stems and not over the foliage. Water deeply and less frequently than a little bit every day, giving the plant time to soak into the soil and roots before the hot summer sun sets. The best soil for this hydrangea type is loam, which is ideal for its well-draining and nutrient rich nature. If necessary, soil amendments can be added to the soil. Overall, hydrangeas require a balanced mix of sunlight, water, and soil to thrive.

Should I cut back my endless summer hydrangea in the fall?

In order to ensure the emergence of flower buds from the winter period, the pruning of Endless Summer Hydrangeas should be conducted in May. This process also serves to remove any dead wood and to leave green buds or leaves, thereby guaranteeing the survival of the plant during the winter season.
