Blossoming Questions

I JUST RECEIVED 3 LARGE, BEAUTIFUL BLUSHING BRIDE PLANTS. I LIVE IN NYC AND HAVE TO USE CONTAINERS. CAN I USE STANDARD MIRACLE-GRO POTTING SOIL? OR DO I NEED A DIFFERENT MIXTURE? SHOULD I USE A MIXTURE FOR TREES AND SHRUBS? I WANT TO MAINTAIN THE BEAUTIFUL CREAM COLOR OF THE FLOWERS! THANK YOU SO MUCH!

CAN I PLANT AN ENDLESS SUMMER HYDRANGEA IN A WASHTUB WITH A DRAIN?

I JUST RECEIVED AN ENDLESS SUMMER HYDRANGEA FOR MOTHER’S DAY. SHOULD WE PLANT IT RIGHT AWAY OR CAN WE PUT IT IN A POT? IF WE PUT IT IN A POT WHEN CAN WE PUT IT IN THE GROUND? ALSO, IN IOWA, HOW MUCH SHADE IS PARTIAL SHADE?

CAN I PLANT MY PLANTS IN JUST DIRT?
