How much watering does a small hydrangea plant need daily?

You only need to water it daily if it is outdoors and in a container. If it is outdoors in the ground, you can water 1-2 times a week so that it gets at least 2-3 inches of water, including rainfall. If it is indoors in a container, then water when the top of the soil just starts to feel dry.
