How many months of the year in moderate temperature Northern CA do The Original and BloomStruck hydrangeas bloom?
That’s a great question. Following the guidelines in our Endless Summer hydrangea planting and care guide will help maximize the flowering potential of your hydrangeas. Proper pruning, fertilizing, and watering all make a difference. You can expect flowers from early summer through fall. And, flowers can be left on through the colder months to extend the season of interest. Your zone 10 garden is on the warmer edge of our recommended zones. Be certain to site them where they can get afternoon shade and give them adequate moisture.
