Since these perennials get so large, certain things are crucial, such as placement. You’ll want to ensure you’re planting them in a space where they have plenty of room to branch out without smothering other plants.

1. Check your USDA Growing Zone

If you live in the United States, it’s always best to check what plants grow best in your area before you even plant. Checking for zoning can ensure the success of your hydrangeas. These plants work best in zones 3 to 7.


2. Water Your Hydrangeas Correctly

Hydrangeas are thirsty. They absolutely love nutrient-rich, well-draining soil that has the perfect moisture. These fast-growing plants need a lot of sustenance to keep up with their speedy growth. Overwatering is possible, but it’s much more detrimental to the plant to let them get completely dry. So if you live in a very dry climate, ensure that you supplement rainfall with watering.


3. Add Fertilizer to Your Hydrangeas

You can use organic or commercial fertilizer for hydrangeas. You can absolutely offer fertilizer to your hydrangeas. Even though they love being in soil with an abundant organic matter source, they will take all the extra help they can get.

5. Prune Your Hydrangeas as Needed
