Pruning a large number of plants can help them regenerate, resulting in gorgeous new foliage and blooms. A plant that benefits from this method is the Endless Summer Hydrangea. Pruning them in the spring is the best way to get them ready for the upcoming season. With a little effort today, you’ll reap the benefits in the form of healthy growth in the coming year. One of the few hydrangea kinds that blooms the year after it is clipped is the Endless Summer variation. Hydrangeas with the name “Endless Summer” are those that bloom for the majority of the summer in either pink or blue. Even if your hydrangea isn’t an Endless Summer, the best time to shape and size it is right after it finishes flowering if you aren’t sure of its variety. This will ensure that you don’t mistakenly remove the buds that it will produce in the future.
It is advisable to use a pair of clean bypass pruners (those that cut like scissors). The use of home cleansers, such as Lysol, can assist prevent the transmission of disease by cleaning pruners. When you’re cutting back your hydrangeas, make an angled cut away from the buds. In order to get a lovely form, it’s best to prune the center somewhat higher. Remove any branches that cross each other if possible.
During the growing season, pruning can be continued to remove any sick, damaged, or dead material. If you prune your plant outside of these times, you’re leaving it vulnerable to stress and illness.
CARING FOR ENDLESS SUMMER HYDRANGEAS
In the northern latitudes with harsher winters, the Endless Summer hydrangea series is a breakthrough in breeding.
To produce flowering buds, the older hydrangea kinds tapped into the previous year’s development. All blooms for the following year were wiped out after that growth was wiped out by severe winter weather, damage, or inadvertent fall trimming.
Plants from the Endless Summer series can be grown on both new and old wood, making them more adaptable in the landscape. When plants aren’t properly nourished in the spring, the current season’s development will generate few, if any, buds.
PLANT PLACEMENT AND PLANTING
You should plant any Endless Summer variety where it gets early sun and afternoon shade, either in an easterly direction. Use a high-quality compost to improve the soil’s ability to retain water and nutrients.
Use Holly-tone or Plant-tone and granulated lime in the spring to fertilize your Endless Summer Hydrangeas for blue flowers.
During the months of April, May, and June, we recommend applying 1 cup of fertilizer per foot of branch spread. It would take 9 cups of fertilizer to feed a 3 foot wide plant for three months. After this time, do not fertilize the plants.
Summer never ends in this paradise In the fall, hydrangeas should not be pruned. The best time to prune your trees is in the spring, in May. As a result, the flower buds that made it through the winter will now be able to bloom.
Leave any green buds or leaves that are still attached to the tree in place of removing all of the dead wood.
Long-Lasting, Colorful Blooms
Endless summer hydrangeas are a one-of-a-kind shrub in that they bloom continuously from spring into 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 white, pink, violet, and blue hues of the eternal summer hydrangea plant are well-known. Hyacinths that bloom on both the old and young woody stems are known as hydrangeas that bloom on both. Endless summer hydrangeas have all of these characteristics, making them a versatile and colorful plant that may be enjoyed from April through fall.
Pick the Perfect Placement
When it comes to growing unending summer hydrangeas, location is everything. Planting your hydrangeas in a position where they are likely to produce blooms is critical, especially in northern regions. Hydrangeas that are grown further north, such as those planted in the United States, are more fragrant. USDA hardiness zones 4-5a can withstand greater sunlight.
Plant as many hydrangeas as you can in a spot that gets plenty of morning sun and a little afternoon shade. Endless summer hydrangeas are more susceptible to sunburn in the south. Consider sites with two to three hours of early sunlight and part shade in the afternoon in these regions.
Prep the Perfect Soil Conditions
Hydrangeas need rich soil, so make sure yours is ready before planting. There are two types of soil that are best for these plants, sandy loam and clay loam. Gray mold, snails, powdery mildew, ringspot virus, rust, and leaf spots are all common pests that can harm hydrangeas.
Hydrangeas thrive in soil rich in organic matter. 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 can result in a lack of flowering.
Pruning Do’s and Don’ts
- DO:During the summer months, be sure to prune the unending summer hydrangea’s flowers.
- The best method to do this is to cut the oldest stems down to the base. This kind of care will aid to promote growth and branching in the plant.
- Pruning in USDA plant hardiness zones 4 and 5 is not recommended unless absolutely essential. Do so as soon as the flowers begin to open.
- Maintain the hydrangea’s extended summer by removing only the dead stems in the early months.
- Pruning all of the stems to the base is necessary if the plants are damaged or old. Initially, this may cause the plant to lose its blossoms for the upcoming season, but in the long run, this will rejuvenate the everlasting summer hydrangea plant, allowing it to bloom and prosper for years to come.
My hydrangea grows beautiful green leaves, but I haven’t seen any blooms yet. How do I get my hydrangea to bloom endlessly?
Some of the most common causes of hydrangea shrubs not blooming are over-watering, over-fertilizing, and sun exposure. Morning light and midday shade are ideal for Endless Summer® hydrangeas. When grown in full sun, the plants may not be able to produce enough blossoms. In addition, over-watering and over-fertilizing your plants can reduce their ability to produce blooms. One fertilizer treatment in the spring or early summer is all that is needed for hydrangeas.
I pruned my hydrangeas back after an early frost and now I am not seeing blooms. Why is that?
How to trim hydrangeas is a terrific question that many people are interested in answering. Hydrangeas that have been clipped at their base will take some time to grow and produce blooms. Keep an eye out for the plants’ roots sprouting new growth. That’s where you’ll get your new blossoms!
I had several small blooms on my hydrangeas last year, so this year I have fertilized every 10 days until I saw blooms starting to develop. What else should I be doing to get big blooms?
Avoid over-fertilizing your hydrangea plants as the first rule of thumb. Once in the spring or early summer, apply granular fertilizer according to the manufacturer’s instructions. Over-fertilizing your hydrangea shrubs can damage their roots and prevent them from blooming.
My hydrangeas have brown dry spots on the leaves and brown petals on the bloom. What do I need to do to make the hydrangeas healthier?
Anthracnose is likely if the spot is circular and brown, with a crimson or purple ring around it. Remove the afflicted leaves from your plants and dispose of them. If necessary, apply a fungicide and treat again. If the edges of the leaves turn brown or grey, the plants have been exposed to too much dryness. If the tips of the flower petals turn brown from lack of water, this is a red flag. It doesn’t take long for leaves and flowers to exhibit signs of dehydration.
I planted my hydrangeas in a location with at least 6 hours of full sun and partial afternoon shade. I read online that hydrangeas prefer that I water them heavily once a week instead of a little water every day. Now my hydrangea bushes are turning brown with no blooms. What am I doing wrong?
Depending on where you live in the United States, the amount of sunlight your hydrangeas can withstand can vary. Your hydrangeas can tolerate up to six hours of morning light in northern states (Zones 4–5b), but if you live in a southern state (Zones 6–8), you will need to provide your plants with extra shade. If you live in Zones 8–9, we recommend no more than two hours of morning sun exposure. Your hydrangea plants can be damaged by overexposure to the sun. Make sure to check the soil with your fingers to determine if it needs watering as well. By inserting your fingers in, you can ensure that the soil is always damp, but not wet, rather than saturated. Give it a nice soak if it’s already dried up. If it’s already moist, there’s no need to add more.
Do these hydrangea plants survive in containers? Our garden gets really hot, so I think a container would be a better option. Do I follow the same care instructions (watering, fertilizing, etc.) as I would in the garden?
Absolutely! Hydrangea bushes make excellent potted plants since they can be moved around the house to serve as a decorative focal point. Most of the care recommendations are the same, but there are a few key modifications to be aware of.
What type of fertilizer do you recommend? I know that hydrangea bushes do best with certain kinds of fertilizer because of their big blooms, but am not sure what to buy!
The recommended NPK ratio is 10-30-10 for granular, slow-release fertilizer. If you can’t find a fertilizer with a high percentage of phosphorus, ask your local nursery for a recommendation.
I bought these plants because I wanted big, beautiful blue hydrangea bush in my garden. I got big blooms, but they are PINK! What did I do wrong?
Hydrangea hues are determined by the pH level of your soil. It doesn’t matter whether you have a pink hydrangea and you desire a blue one! The pH of the soil must be lowered to produce an acidic environment for pink blossoms to thrive. If you want to grow blue flowers, we recommend using Color Me Blue soil sulfur. This is completely risk-free, natural, and organic. Changing the color of hydrangeas naturally can be accomplished in other ways as well. Add aluminum sulfate, composted oak leaves, pine needles, or coffee grounds to alkaline soils to encourage blue blooms.
I planted my Endless Summer hydrangea in an area that is far too sunny and hot, so I’d like to transplant them to a more shaded area. What is the best time of year to do this, and are there any other tips I should know?
If you’re going to move your hydrangeas, wait until they’re dormant before you do so. After the first frost in the fall or early spring, you should transplant your hydrangea shrubs to a new location.
I live in an area that gets a lot of snow during the winter. Should I prune Endless Summer Hydrangeas back like I do with my other hydrangea bushes? What else should I do to protect them from the freezing winter months?
Other hydrangeas must be pruned all the way back to the ground, but not with Endless Summer® hydrangeas. Because they bloom on both old and new growth, you can leave them in the ground all winter to get twice as many blooms in the spring. Hydrangeas should not be pruned back in the fall. To avoid plucking flower buds that will come up later in the spring and summer, leave the fall blooms on your plants over the winter. To keep your plants warm, use leaves, wood mulch, or straw. Mulch or leaves should be piled at least 12″ high around your plants to preserve the buds that will bloom in the spring of 2017.
