Is morning sun or afternoon sun better for hydrangeas?
Keep new plants well-watered until established. Knowing where to plant hydrangea shrubs is an important first step. Many people plant hydrangeas in beds next to their homes or fences. This is because hydrangeas love the warm morning sun, but they dislike the heat of the afternoon.
Too Much Sun
Hydrangeas love morning sun and afternoon shade, and the farther south you get, the more shade hydrangeas will need. "If you live in zone 4, you can get away with almost full sun," says Mcenaney.
Hydrangeas thrive with that perfect combination of morning sun and afternoon shade. Even Hydrangea paniculata, which is a sun lover, will do well in partial shade. However, some varieties of hydrangea can tolerate full shade.
Hydrangeas prefer a partly-shaded garden, ideally with four hours of direct morning light and several hours of dappled light or shade thereafter.
Hydrangeas can be grown in full sun but too much direct sunlight, especially during the afternoon hours when the sun is most intense, can cause wilt. When exposed to excessive sun, the plant's internal temperature increases, which causes the leaves to transpire and leads to moisture loss in the cells.
quercifolia) will do better with part shade. If your hydrangea is getting too much sun, its leaves will wilt and/or may appear scorched. Flowers often fade quickly and turn brown. The best solution is to transplant your hydrangea to a spot that gets a bit more shade.
TOO MUCH SUN
Conversely, too much direct sun may stress hydrangea plants, which can force them to conserve energy by not forming flowers. Some types such as panicle hydrangea (H.
Endless Summer hydrangeas should be planted in a place that receives morning sun and dappled afternoon shade. "The amount of sun they can tolerate depends on the zone," says Mcenaney. "Endless Summer hydrangeas that are planted in zone 4 can tolerate more afternoon sun than those planted in zone 9."
The combination of too much sun and not enough water is a common cause of hydrangea droop, making it a great place to start when your plants are feeling unwell. Check the moisture level of your hydrangea at a point 1 to 2 inches (2.5-5 cm.) below the surface of the soil with your finger.
What is the most shade-tolerant hydrangea?
Hydrangea macrophyllas, commonly known as 'Big Leaf Hydrangeas', are ideal for almost any shade setting & are prized for its large flowers and dense foliage.
What Time of Day To Water Hydrangeas. If watering at twilight is part of your routine or grabbing the hose around mid-afternoon is what you think is best for staving off the worst of the summer heat, you might want to consider making a switch to the early morning hours.
Hydrangeas need more water than most garden plants and will begin to wilt quickly without it. To ensure that Hydrangeas thrive, water deeply two to three times a week in the summer. Be sure to water in the morning or evening so that water does not evaporate as quickly as it would during the heat of the day.
In order to figure out how much water your new hydrangea needs, start by watering it two-three times per week (less in spring and fall and more in summer) and checking the soil in between waterings. Use your finger to feel into the soil around the base of the plant and check for dryness.
Alum Treatment
To do this, re-cut the stem about an inch above the previous cut and immediately dip the bottom ½” of the stem in alum powder (aluminum sulfate), which can be found in the spice aisle. This will help keep your hydrangeas looking fresh and beautiful without wilting.
Deep weekly watering is usually enough (if you don't get enough rain). Although you may need to water more often in hot, dry weather. Water hydrangeas deeply and regularly in the first growing season to encourage an extensive root system.
Most common hydrangeas prefer a partial sun location - ideally receiving sun in the morning hours and shade in the afternoon.
Should I Cut Off Brown Hydrangea Leaves? The short answer is, “it depends.” While damage to leaves is unsightly, they can and will recover if you identify the problem and implement the solution early enough. As a general rule of thumb, we recommend removing leaves when they are 50% brown or higher.
Ugly as it is, the best thing to do about burnt growth is to leave it be and to provide as much water as possible to damaged plants. Regular deep watering along with a weekly application of a seaweed tonic (not one containing any fertiliser) helps plants to recover.
Many people think that you need a shady garden in order to grow hydrangeas. While that is true for some varieties, some hydrangeas thrive in sunny spots and even need full sun to develop into the fullest plants and the brightest blooms.
What happens if you don't cut back hydrangeas?
If you don't prune hydrangeas then they can eventually resemble a tangled mass of woody stems, and the flowers will become smaller and less showy.
Yes, you can use many types of all-purpose balanced Miracle-Gro on Endless Summer hydrangeas. This includes the new OMRI-approved organic multi-purpose Miracle-Grow products.

If you catch and treat your hydrangeas when their blooms first start turning brown, Myers says there's a good chance you'll be able to turn them around (as long as it's not due to weather damage). "However, once they turn fully brown, there's not much you can do," she says.
How do you keep Endless Summer hydrangeas blooming? The best location to ensure continuous bloom is one where the plant receives morning sun and afternoon dappled shade. In too much sun, they might stop blooming.
Hydrangea Heat Stress
Heat and drought stress can cause the stomata of your hydrangea plant to remain open as they try to absorb water vapor from the environment that they are in. Unfortunately, this causes water to be lost more than it is gained which over time translates into wilting.
While hydrangeas typically prefer sun in the morning and shade in the afternoon, there are full-sun hydrangeas. Dial Mild. While you can plant hydrangeas at any time, the best time is spring or fall.
Water your hydrangeas in the morning before the heat of the sun is strong enough to quickly evaporate soil moisture. Try to avoid watering at night, which can encourage mold and mildew as the moisture sits through the cool night. Water your hydrangeas through the growing season as well as in late fall.
The hydrangea should be watered thoroughly at least 3 times a week. Always water the plant all the way around the container, not just in one place. Water should come out the bottom of the pot. Never let it sit in water which will cause the roots to rot away.
To help Hydrangeas thrive, give plants a deep soak 1-3 times a week rather than giving them little sips of water daily. Hydrangeas do not tolerate overwatering or drought well. Their leaves wilt in the heat of midday, making it difficult to tell by appearance whether they need additional water or not.
Place the hydrangea(s) in the vase filled with hot water. Let sit for a minimum of one hour and voila! Revived hydrangeas.
How do I protect my hydrangeas from hot sun?
Shade cloth is available at many garden centers and home improvement retailers. It comes in different densities so get the one that provides the most shade. This is a temporary covering. You set out wooden stakes around the plant(s) and then drape the shade cloth over the plant(s) using the stakes for support.
For hydrangeas planted in ground.
For optimal growth, bloom production, and quality, fertilize three times: In early spring when plants are just leafing out. In early May to boost their flower production for summer. In late June/early July to help your plants finish the summer strong.
Not Enough Light
Hydrangeas grow best when they receive bright morning light and part shade in the afternoon. Plants growing in too much shade will have few flowers and elongated, floppy stems.
But hydrangeas are among the few plants that can draw moisture in through their florets, so it's possible to perk up wilted blooms by completely submerging them in water and letting them sit for a few hours to rehydrate.
Endless Summer Hydrangeas live up to their name, blooming massive pink or blue mophead flowers on both old and new wood all summer long. Endless Summer Hydrangeas are unique, taking the traditional hydrangea to the next level.
