Endless Summer Hydrangeas planted in May and the flowers are turning brown. Please help.
This could be a number of things--too little or too much water, over fertilizing, leaf scorch (if planted in too much sun), etc. Typically, in hydrangea, this is caused by a watering issue. Has it recently been planted? If newly planted, there may be gaps in the soil around the root ball that is drying out the roots. I would tamp down the soil around the plant. I would also recommend upping the watering. Hydrangeas need to be kept unifromaly moist, but not soggy. It is a good idea to check the soil with your finger and water if it feels dry to the touch about an inch or so. If it's still moist, do not water. You can remove the browning leaves and they should regrow once the plant recovers.
In addition, it could be suffering from shock. This article will help with that: https://www.gardeningknowhow.com/plant-problems/environmental/learn-how-to-avoid-and-repair-transplant-shock-in-plants.htm
I just got a hydrangea bush. I need to know how tall and wide it will grow. It's the endless summer type. I live in Maine (zone 4). Not sure if I should plant it in one of my flowerbeds, or create a spot in the lawn. We have clay soil.
Endless Summer is hardy down to zone 4. I would mention that I also garden in zone 4 and was not able to winter mine over successfully.
The Nikko Blue variety is a more stem hardy variety and may preform better in your garden.
Endless Summer plant will mature to 3 - 5 feet width and height.
You may want to condition and amend the clay soil prior to planting.

My Sweet Summer Hydrangea is completely flopped over due to large flower heads. Should I tie the shrub up at the base to support the weight of the flower?

My everlasting hydrangeas are very overgrown, and over living room windows. Still has a few blooms coming out. How to cut them and will they come back next year?
Since Endless Summer plants bloom on both old and new wood there is no hard and fast rule.
Go ahead and prune this fall to clean up it's shape and size. Since you have not pruned in a while I would try to cut about 1/3 from the plant.
Then in the spring you can clean up any bare branches or branches that are touching or crossing each other.
I bought an Endless Summer white hydrangea with a hint of light blue on the edge of the bloom. This last year, it got very dark purple (almost black) blooms. How can I change it back to white or mostly white but certainly away from the dull dark purple? Please advise.

Why is my endless hydrangea not flowering? Even if I cut it back or not, it will only make one flower at the bottom of the plant.
Young Endless Summer Hydrangea should not be pruned. Let them mature and become established.
Dead head the flowers throughout the summer. Cut the spent flower off at the leaf node just under the flower.
If you plant is more mature, do not prune the old branches from the plant until the leaves have all began to push through the ground and are full size.
Lack of flowers is generally too much sun, improper watering and over fertilizing.
Moist not wet soil and only fertilize once in spring or early summer.
Too much nitrogen will inhibit flowering.
You may want to do a soil test. A boost of phosphorous can encourage flowers. Bone Meal is a good way to add phosphorous.

The leaves look rusty on my Endless Summer hydrangeas. All of my others look fine.
This is most likely Rust Fungus.
