Long-Lasting, Colorful Blooms
Unlike other types of hydrangeas, Endless Summer Hydrangeas are able to re-bloom throughout the spring and summer. When it comes to blooming duration, the hydrangeas of the ‘endless summer’ kind are often 10 to 12 weeks longer than traditional hydrangeas. In chilly climates, hydrangeas thrive. Both old and fresh growth can produce flowers.
The beautiful white, pink, violet, and blue hues of the eternal summer hydrangea plant are well-known. Unlike other types of hydrangeas, these bloom on both the current season’s growth and the previous year’s woody stems. Summer hydrangeas, with these characteristics, are a plant with numerous options and a wide spectrum of vibrant hues throughout the months spanning from spring to fall.
Pick the Perfect Placement
Choosing the right spot is essential if you want your summer hydrangeas to thrive. The area where you plant your hydrangeas, especially in northern regions, is particularly significant for flower output. Hydrangeas that are grown farther north, such as those grown in the U.S. Department of Agriculture plant hardiness zones 4-5a, can handle more sun.
Prep the Perfect Soil Conditions
Hydrangeas that bloom all summer long require the right kind of soil and climate. The area where you plant your hydrangeas, especially in northern regions, is particularly significant to bloom production. Northern-grown hydrangeas, including those in USDA plant hardiness zones 4-5a, may tolerate more direct sunlight.
A significant degree of organic material is required for the growth of hydrangeas. This form of organic material aids in water drainage by creating air pockets in clay soil. In order to thrive, Hydrangeas require a soil that is damp but not soggy. Overwatering might reduce the number of blossoms in your garden.
Pruning Do’s and Don’ts
- DO:During the summer months, be sure to prune the unending summer hydrangea’s flowers.
- DO: Remove a few of the oldest stems and cut them all the way to the ground. Maintenance like this promotes branching and fullness.
- Pruning in USDA plant hardiness zones 4 and 5 is discouraged unless absolutely essential. Do this as soon as possible after blossoming, if necessary.
- Maintain the hydrangea’s extended summer by removing only the dead stems in the spring.
- Prune damaged or old plants to the base of the stems completely. To begin with, this may cause hydrangeas to lose their blossoms, but it will eventually bring back the plant’s perpetual summer and let it to bloom and thrive for years to come.
PLANT PLACEMENT AND PLANTING
An easterly placement or a spot in the garden that receives morning light and afternoon shade is ideal for any of the Endless Summer types. Use a high-quality compost to improve the soil’s ability to retain water and nutrients.
To get blue flowers, use Holly-tone or Plant-tone with granulated lime in the spring. For purple to pink blooms, use Plant-tone and granulated lime.
During the months of April, May, and June, we recommend applying 1 cup of fertilizer per foot of branch spread. Over the course of three months, a three-foot-wide plant might receive nine cups of fertilizer. After this time, plants should not be fertilized.
Forever in the Sun Fall is not the time to prune hydrangeas. The best time to prune your trees is in the spring, in May. Make sure the flower buds that survived winter are ready to bloom.
Leave any green buds or leaves that are still attached to the tree.
Endless Summer Hydrangea Pruning Tips You Need to Know
Bigleaf hydrangeas, or H. macrophylla, include the everlasting summer hydrangea. Shiny leaves and brightly colored blue, red, pink and purple blooms make this plant a standout. Pruning them can be tricky, so here are some pointers.
Tip #1: Use sharp and clean pruners
As you trim back the hydrangeas’ stems just above their sets of leaves, make sure to use sharp and clean pruners.
Tip #2. Prune only when new growth emerges in the early spring
If you don’t cut these bigleaf hydrangeas, they can get overrun. If you over-prune them, though, you run the risk of limiting their blossoming potential. Because of this, it’s ideal to begin trimming in the spring as soon as you notice new growth.
Tip #3: Test the stem for life
It’s important to check the stem for life before you cut it down, so you don’t remove any of the living portions of the shrub, such as the flower buds, instead of the dead and weakening parts. Use a knife to scrape the bark off of the tree. While a winter-killed stem is brown, a live stem is green.
Tip #4: Do hard renewal pruning on old and declining endless summer hydrangeas
For hydrangeas in their late teens or early twenties that are showing indications of deterioration, it is preferable to prune them severely for rejuvenation. Cutting all of their branches to the ground will suffice. Although doing so will eliminate its chances of flowering within that year, you can be sure that a more vigorous bloom will be produced the following year.
Tip #5: Remove flowers that are old and dried
The safest approach to prune hydrangeas is by removing old, faded blossoms, a procedure known as “dead-heading.” It’s nearly hard to make a mistake here.
