Hydrangeas have wonderful colors, and in your garden you will find that they will give you a great relaxing scent as well. If you want to brighten the color of your hydraneas use these tips:
Keep your Hydrangeas a bright pink by adding a pinch of iron sulfate every 3 weeks when you water which is just what they love.
Keep your blue Hydrangeas bright and thriving by adding a pinch of aluminum sulfate every 3 weeks when you water and you will notice a longer lasting color.
