Homeowner Growing & Maintenance

Hydrangea is easy to grow and adapts to most conditions. Feed once a year with a slow release fertilizer. To give your plant the best start possible, we include free fertilizer with every order.

Interesting Notes

Hydrangeas produce beautiful pink or blue blooms depending on soil pH. Alkaline soils will produce pink blooms, acidic soils will result in blue blooms. To determine whether your soil is alkaline or acidic, ask your garden center professional or State Extension Agent how to obtain a soil test. If the pH is just right you may have both pink and blue flowers on the plant at the same time. Change from Pink to Blue: Add aluminum sulfate according to package directions, to lower the soil pH. Your soil will produce blue flowers at a pH level of about 5.2 - 5.5. Change from Blue to Pink: Add dolomitic lime according to package directions, to raise the soil pH. Your soil will produce pink flowers at a pH level of about 6.0 - 6.2.
