My hydrangea's flowers are green, what can I do?

The flowers on my hydrandea are coming in green instead of blue or pink. I would like them to be blue when they come in. What do I need to use to get these results and why are my flowers green?

Just be patient. Hydrangea flowers first set out green and will change color as they mature. Your doing just fine! Blue flowers are usually the results of genetics and acid soil. If your soil is already acidic, you will need to do nothing. If your soil is neutral to alkiline, you can try to acidify the soil with sulfur, peat moss, and pine needle or oak leaf mulch. There are fertilizers like Holly-Tone %26amp; Miracle-Gro? Shake 'n Feed? Continuous Release Azalea, Camellia, Rhododendron Plant Food that help to acidify a soil as well.
Reply:if you want blue flowers, either buy a species that produces blue flowers, or you need to make your soil acidic, since blue flowers are indicicative of an acid soil pH, pink flowers indicate alkaline or basic soil pH, my guess is that your soil is neither acid nor alkaline, but near neutral in pH, so buy a soil acidifier to see if you get the results you want, otherwise you might have picked the wrong species of hydrangea
Reply:Probably need to add acid to your soil to produce the blue color. Sulfur is often used. Here are some other items, sawdust, composted leaves, wood chips, cottonseed meal, leaf mold and especially peat moss
Reply:Epsom salt or aluminum sulfate will turn them blue. Both have sulfur, but epsom salt is more economic
