Is it a perennial ?What is the best fertilizer i can use for its good growth? what is the best climate for good blossoms?since the winter is fast approaching, what can i do to protect the plant from frost?
What r hydrangeas?
The hydrangea is basically maintenance free, other than periodical pruning and the odd multi purpose fertilizer treatment. Don't expect the shower caps in the first through fourth years as the plant needs to mature before flowering. Morning sun is best with afternoon shade.For frost protection just mound six inches of mulch around the root base, but don't forget to remove it in the early spring after ground thaw. Enjoy.
Reply:Hydrangeas are a lovely, hardy flowering shrub.
When they are first becoming established, be sure to keep it well watered, it will droop when it is thirsty.
It prefers morning sun and afternoon dappled shade, but really isn't all that fussy---can grow pretty much anywhere.
The flowers are blue in acid soil and pink in alkaline soil.
If you want to keep them blue, fertilize with an acid fertilizer---one that is recommended for Rhododendrons, for instance.
They are slow to come out of winter hibernation, so don't assume they are dead in the spring if they look like bare twigs for some time.
I under-plant mine with daffodils and grape hyacinths which will bloom in the spring. When the hydrangea finally leafs out, it will camouflage the bulb foliage which must be allowed to yellow and dry up.
There are some new varieties called "Endless Summer" which I highly recommend. They bloom and bloom and bloom! All you have to do is snip off the spent flowers to encourage re-blooming.
Enjoy!
Reply:Coffe grounds and tea bags (used of course) will encourage blue flowers. Rusty nails or copperas will encourage pink blossoms. Epsom salts is a cheap alternative for acid fertilizer (azaleas, camelias, gardenias love it) have fun!
Reply:They are hardy with large "snowball" flowers. It's almost impossible to kill them. The amount of sulphur in the soil will determine color. They will lose their leaves in winter, but they will be back.
Reply:There are several types of hydrangeas, with hardiness zones varying from 3 to 9. More info here: http://www.hydrangea.com
They prefere acid soil type - available on the market.
Flower colour is influenced by the soil type (pH)

How do you get rid of pests on hydrangeas?
My hydrangea plant has brown spots on it indicating some kind of pest. How do I get rid of them?
Hydrangea lovers - I bought some Aluminum Sulfate to add to my Hydrangeas - has anyone done this before?
How much per plant and how long does it take to get blue flowers?
Hydrangea lovers - I bought some Aluminum Sulfate to add to my Hydrangeas - has anyone done this before?
It depends on your beginning soil pH.. if you know that, it's easier to offer an opinion.
I'd start out at a minimal rate.. look at the directions on the package for guidelines. If the package calls for 2 lbs, use 1 and see what happens.. you can always ad more, but you can't take it back out.
good luck!

Why do hydrangeas change color when dolomitic lime is added (pink) or when aluminum sulfate is added (blue)?
Is there some sort of chemical reaction that happens between something in the hydrangea and the added substances? or what is the cause for the color change?
Why do hydrangeas change color when dolomitic lime is added (pink) or when aluminum sulfate is added (blue)?
Hydrangeas will be red in acidic soil, and become blue in base soil.
dolomitic acid produces acid, and it'll decrease the pH of the soil. Thus it'll be pink.
Aluminium Sulphate will increase the pH of the soil and make it become basic, and it'll turns hydrangeas flower into blue.
Reply:Different chemical compounds have different colors because different wavelengths of light are absorbed and/or reflected by their molecules.
When you add stuff to the soil, it often causes changes in the chemical composition of the pigments in the flowers.

Do hydrangeas come in red?
Yep, there's one called 'Cardinal Red' and it's just beautiful !
There are some great pictures at :

Do hydrangeas come in red?
hydrangeas change color depending on the soil chemistry, so it's probably possible to grow dark pink blooms that way.
I've never actually seen one, but you can find plants online that claim to be red in color.
Reply:No, they come in the following; pink, purple, blue, white, green ...... and one call red star butt it not red.
Reply:I've never seen one I've only seen white/green blue and pink.

My hydrangeas are just about to bloom. Is it too late to add lime to the soil to make the blooms blue?
What would happen if I added it now? Thanks.

You need Epsom salt for deep blue flowers. It's cheap, find it at your local grocery store for around two bucks. I used it last year while my flowers were blooming, and they were the deepest blue ever. love Hydrangea!
Reply:aluminum sulfate and acidic soil makes them blue.... lime will make them turn pink... but it can take a year or more for the change to happen and that's if you consistently add alittle of this and that as you decide, often over the year..... it's much easier to turn a hydra pink if it's in a pot... in the ground it could take a while.... it's all here...
look on the left for 'color change'...

Reply:Lime won't make them blue, it will make them pink. Lime increases the pH making the soil less acidic. If you want blue flowers you have to make the soil MORE acidic. Garden Sulfer can help a bit, but you really have to add it to the soil before you plant. If you want to turn them blue after the plant is esablished you need to add something else. I forget what it's called but there is stuff you can buy that acidifiys the soil, it actually says right on the bag " Turns Hydrangeas Blue!"
I think it's Ammonium Sulfate or Aluminum Sulfate but I could be wrong.
You can add it anytime, if the flowers have not come out yet, you can still make them blue. If its too late, you will just have to wait until more flowers come out later in the season. It can't hurt to add it now though.

Should hydrangeas come back each year and if so what month?
I live in the midwest if that helps. Thank you!

in warmer regions they come up now. they need 70s for leaves to appear and no frosts. they will come up in a few weeks unless temps were below -15 f this winter if so it died and is only and annual in your zone
Reply:yes they will come back every year, mine is comming back now. I live in the east coast. mine is about 2 ft. tall also u can change their color but putting different things to them. also the soil in another part off your yard will change the color
Reply:as long as the frost and sub freezing temps do not kill them they should be blooming right now literally
Reply:They'll come up again every Spring, and last through most of the summer.
Reply:Yes, they are a perinnal and will come back each year. Mine are just now starting to "pop" out of the ground. I too live in the midwest.
