Its the first me that I put my gardening output to share with everyone. My friend bought these 2 hydrangeas for me on one summer night and hoped me to take good care of it. I water the flowers twice a day, morning and evening. Finally, it bloomed. One day, after a sudden rain, the flowers changed their colors, from the light blue ones to the dark purples ones. I checked the web saying that the PH value of the soil could help to change the colors of the flowers. I like the pink hydrangeas very much, and I would add some fertilizer to change the flowers into the light pink ones.
