How do you make Hydrangeas bloom pink?

I recieved my hydrangeas pink. Now they are blooming blue. I was told it had something to do with the acid in the soil, and someone else said I need lime in the soil. Someone said I have too much lime in my soil. I did have my soil tested and the readings said my ph was right on.

How do you make Hydrangeas bloom pink?
Add lime to your soil. Lime is basically crushed limestone. It comes in powder or granular form and can be purchased at any nursery or garden center. The lime will lower the acidity of your soil. Acidic soil will make your flowers blue, neutral soil will make your flowers both pink and blue on one plant or change them completely to purple. Lime will "sweeten" your soil and change your flowers to pink. Whoever said there was too much lime in your soil was mistaken. The problem is actually the opposite.
Reply:Your soil must be high in iron content, the only way you can get it to have pink blooms is to plant it in a huge pot of iron free soil.
Reply:ADDING 1 CUP OF LIME TO THE SOIL AT PLANTING TIME WILL PROMOTE BEST COLOR.

Reply:Here is a good one for you. I have two bushes. Each year they are a different color! One will be pink and then the next year blue.





I honestly think they change every other year. I have seen some with three or four different colors at the same time. Someone told me it had to do with their age...........My soil couldn't change one way and change back the next year!!!!! I don't know how the soil could determine color anyway.
Reply:I know to turn them blue you need an acidic soil...and can use aluminum sulphate to do this..but sorry I'm unsure of how to turn them pink....but I believe that lime is the way to go to get pink.
Reply:its right on for normal plants, but you add acid to make them blue and add alkali to make them pink, so yes, add lime. or ask at a garden shop. they know more than we do.
