What do you add to make Hydrangeas Blue?

I was told you add something to the soil to make them blue, what is it?! I purchased them blue and planted them in the garden but would love to have the blue.


What do you add to make Hydrangeas Blue?

Hydrangeas require and acidic soil to produce blue blooms. Miracid will turn them blue but I would steer you against it due to the dependancy your plant would build up always having the esstential nutrients handed to it in a readily available form. To maintain the blue hydrangea add Aluminum Sulfate usually found at any local garden center. To maintain their healthy state use Holly Tone. It will also maintain the blue color of your Hydrangea as well as feed it and replenish the soil with the 15 essential nutrients that a plant needs and processes from the soil. One application in the Spring and one application in the Fall is all you need. Goodluck!

Reply:That is a Great way to grow them,

The Garden has a book on them as well , Report It

Reply:That would be Miracid, which is a fertilizer that also acidifies the soil.

Adding: it's now called Miracle Gro for Azalea and Camellias. Same thing, just renamed. :)

Also, aluminum sulfate will keep your blooms blue. This might be what you're looking for!
Reply:The soil needs to be acidic..I went natural with mine....pine trees are acidic and I put pine mulch around my endless summer cant touch the plant with the mulch. But my flowers are blue. Next year I want to plant one right under my pine tree...perfect conditions with the morning sun and afternoon shade. My endless summer is my favorite plant!!
Reply:they turn blue with acidic soil, pink with more alkaline

If your soil needs to be more acidic, sulfur may be used to lower the pH if it is available. To reduce the soil pH by 1.0 point, mix in 1.2 oz of ground rock sulfur per square yard if the soil is sandy, or 3.6 oz per square yard for all other soils. The sulfur should be thoroughly mixed into the soil before planting. Sawdust, composted leaves, wood chips, cottonseed meal, leaf mold and especially peat moss, will lower the soil pH.
Reply:above is true but I hear that pine needles are also good for helping with acidity.
Reply:If you want your Hydrangea to be blue, add Aluminum Sulfate.

Oh, and also Hydrangeas will like to have acidy soil for them to be blue. I have mulch around mine, its blue. I just got it last month.
