Do Bloomstruck hydrangeas tolerate direct sunlight?
Hydrangeas don’t require pruning, although after they finish blooming, pruning can assist promote bushier growth and rejuvenate an older plant.
In zones 4 through 9, plant in the early spring or fall in a location with well-drained soil and full sun to part shade conditions.
Make sure your Bloomstruck Hydrangea is planted in a location and under conditions that will allow it to flourish. Hydrangeas grow best in the spring and fall. In the summer, when the temperature is in the mid-80s or higher, avoid planting hydrangeas.
Watering
In the summer and the first year after planting, keep the soil wet but not waterlogged. Hydrangeas benefit most from a deep watering once per week in hot weather throughout their whole lifespan.
Mulching hydrangeas at a depth of about 3 inches is highly advised. Mulching will reduce your plant’s requirement for watering and protect it from harsh weather.
Fertilizing
If you want a blue hydrangea and your soil is alkaline, make sure to amend it. Add aluminum sulfate or elemental sulfur to your soil to acidify it. Add lime several times a year to achieve a pink color.
For flowering plants, pick a fertilizer with a delayed release. For optimal results, fertilize once in the spring after the last chance of frost and once again in the early summer.

Hydrangea macrophylla ‘PIIHM-II’, also known as the Bloomstruck Hydrangea, is a deciduous blooming shrub with stunning mophead-style hydrangea flowers. These plants can bloom slightly earlier in the spring if the conditions are right, though they normally bloom from July to August. Endless Summer, which is well known for its classic Endless Summer Hydrangea and more recent Summer Crush variety, sells the BloomStruck Hydrangea.
The Bloomstruck Hydrangeas produce huge clusters of flowers. Because the color of the flowers can change depending on the pH of the soil, this species of hydrangea is well recognized. Bloomstruck hydrangea flowers can be dyed a vivid pink with garden lime. Using a soil acidifier, Bloomstruck hydrangea blossoms can become purple or blue (see details in the following sections).
Especially in the summer, the dark green leaves mostly encircle the reddish-purple branches. In the fall, branches plant flower buds for the following spring’s early flowering. This hydrangea’s reblooming variety also develops flower buds on young, springtime stems that are fresh and green.
The Bloomstruck Hydrangea can reach heights of 3 to 4 feet and widths of up to 5 feet. Make sure not to put Bloomstruck Hydrangeas too closely to one another because these are plants that require a lot of space to grow.
How long do Bloomstruck hydrangeas last?
From Zones 4 to 9, hardy. This plant is exceptionally resistant to cold. However, a large part of this is because it is a deciduous plant. As a result, after the first freeze of the year, it will shed its leaves and sprout new ones the next spring.
In all zones, place the Bloomstruck Hydrangea in some shade. These Hydrangeas can tolerate some sun, though. Gardeners in the Northern US should allow about 3 hours of direct sunlight, whilst those in the Southern US should limit this to no more than 1-2 hours. As they are highly prone to scorching from too much direct sun exposure, err on the side of caution.
In times of drought, supplementary watering may be required to maintain the success of hydrangeas because they require continual moisture to thrive. Additionally, while the plant is establishing itself, we advise watering them a few times weekly. This will aid in the establishment of strong roots that can access water buried deep in the soil.
The root rot that results from standing water will hasten this plant’s demise. Soil that drains efficiently is therefore crucial.
Late spring or summer are the best times to fertilize using a slow-release fertilizer. Additionally, fertilizers with a balanced NPK ratio will be effective; nevertheless, you could wish to select one with a higher Phosphorus content. This will promote higher levels of bloom production.
Why aren’t the hydrangeas in my Endless Summer garden blooming?
Your hydrangea shrubs may not be blooming for a few main reasons, including sun exposure, excessive watering, and excessive fertilization. Endless Summer hydrangeas appreciate dappled shade in the afternoon and morning sun. It may be too hot and intense for the blossoms to form if they are placed in full sun.
Should I deadhead my hydrangea that blooms all summer long?
According to Meyers, the species of hydrangeas will determine the optimal time to prune them. When the initial set of flowers emerges from the previous year’s growth in the spring on bigleaf hydrangeas like Endless Summer, she advises, “deadheading to remove the faded blossoms before the next flush arises.” As long as the cut is made before July or August, when the plant starts to create buds for the blooms of the following year, you can make a deeper cut for a longer stem. She advises removing the faded blooms off smooth hydrangeas as soon as they turn green in order to guarantee a second flush of smaller flowers in the fall.
When should I trim my hydrangea that blooms all summer long?
For those of us who live in northern climes with more severe winters, The Endless Summer series represents a milestone in hydrangea breeding.
Older hydrangea kinds only produced flowers on old wood or stems that had grown the previous year. All flowers for the following season were gone once that growth was destroyed due to harsh winter circumstances, damage, or unintentional autumn trimming.
The plants in the Endless Summer series are significantly more adaptable in the environment because they bloom on both new and old wood. The plants won’t generate many, if any, buds on the growth of the current season, though, if the plants are not properly nourished in the spring.
Any Endless Summer variety will grow best in an easterly direction or in a spot in the garden that receives morning sun and afternoon shade. To make a richer soil that will store nutrients and fertilizers better and retain more moisture, use a decent compost.
Use Plant-tone and granular lime for purple to pink blossoms or Holly-tone and holly for blue flowers when fertilizing your Endless Summer Hydrangeas in the spring.
We advise fertilizing in April, May, and June with 1 cup of fertilizer for every foot of branch spread for the optimum flowering. For instance, 9 cups of fertilizer would be applied over a three-month period to a plant that is 3 feet broad. After this time, fertilizer shouldn’t be used to plants.
Continual Summer Fall is not the time to prune hydrangeas. Rather, only prune them in May. This will guarantee that the flower buds that survived the winter have opened.
Plants marked with a number sign (#) and a number are generally the same size as gallon pots; for example, #2 is equivalent to a 2 gallon pot, #3 to a 3 gallon pot, and so on. These plants are offered for sale in pots.
Plants with a height (such as 5-6′) give an estimate of the plant’s present height.
Plants that are measured in inches (such as 2.5″) are identified by their caliper, or trunk width.
Plants are typically larger when measured by caliper (inches) than when assessed by height (feet).
Do Hydrangeas Endless Summer bloom again?
The first hydrangeas to bloom on new growth and have the capacity to rebloom all summer long are called “Endless Summer” varieties. This unusual plant will need special maintenance.
Follow these suggestions if you’ve introduced one of these wonderful plants to your landscape to ensure that “Endless Summer” remains the highlight of your yard for many years to come.
The following is advised to ensure overwintering success in the first year:
- After August 15th, cease all fertilizer applications in order to prepare the plant for winter.
- Till the ground freezes in the fall, keep the soil moist.
- Apply a four-inch layer of organic mulch over the plant (wood mulch, leaves, etc.). It is not necessary to trim back or cover all stems all the way to the tip.
When entirely dormant (about November 30), or at the same time as you cover perennials in your garden, covering should be done.
- When the ground is no longer frozen in the spring, you should re-plant your perennials. The plant will expand from its root system and any old branches that made it through the winter.
- Be tolerant. Up until the late spring heat spurs the plant to develop rapidly, growth will be gradual.
- The old branches can be cut back to a finger’s width above the fresh, green growth once you notice it.
- Watch your plant develop and blossom while you relax; depending on your environment, this should happen around the middle of July.
The Endless Summer Hydrangea is quite tolerant and won’t suffer from being neglected or clipped improperly. In actuality, it’s preferable to leave young, recently planted bushes alone. Your Endless Summer will bloom on both old and new wood, unlike other hydrangea varieties (branches that grew last year and new branches from this year).
The fact that this hydrangea will continue to form buds and bloom throughout the season is another distinctive quality; deadheading the spent flowers will promote this. You won’t harm the plant by cutting the blooms; in fact, you’ll stimulate the plant to produce more blossoms. Feel free to dry or utilize the blooms fresh cut in vases. The optimal time to prune is in the spring.
