Hydrangeas are definitely a favorite of gardeners and flower-lovers. If your hydrangea bush has dried out flowers, it is time to snip them off and prune back your hydrangea. It will not produce beautiful blooms for the season of the pruning. But, the cutting will allow the plant to be saved and revive for the next season. It’s important to know the right zone specific to your hydrangea plant. If you put your plant in a cooler zone than it likes to be in it will in all likelihood produce beautiful green leaves, but be unable to produce blossoms, which will die. Your garden center not only has an array of hydrangea plants blooming in the summer, that will allow you to see what sort of flower you might enjoy, but also the specialists should know how to match plant to the zone. If your goal is to have beautiful blue blooms, you will need to ensure the soil is sufficiently acid, which can be done by adding some aluminum sulfate to the dirt, about a cup. Make sure the hole for your plant is sufficiently large and has good drainage and room for the roots.
