I'd love to hear from you if you have a different experience). In other words, acidic soils with a pH of less than 5.5 produce blue flowers; soils with a pH greater than 5.5 produce pink flowers. A few varieties of hydrangeas tend more toward the pink or the blue range of colors, but will not retain even this color if soil conditions are not right.

Blues are best grown in acidic soil; pinks and reds do best in alkaline or neutral soil. TIL that the Hydrangea flower color changes based on the pH in soil. Slightly acid to slightly alkaline soils with a pH of 6 to 7.5 will result in pink flowers. color, and that differing soil pH affects the plantâs ability to absorb salt compounds (see Appendix Two: Effect of Soil pH on Hydrangea Salt Absorption ).
