3 Tips for Growing Hydrangeas in Full Sun

It is tempting to plant a hydrangea in a full sun spot (anywhere that gets six or more hours of direct light), but unless you’re happy to run an experiment you might want to know just how to have success. Let’s touch on the three things you need to know about growing hydrangeas in full sun:

1 – Where you can grow hydrangeas in full sun
Northern gardeners get all the luck in this situation. Anyone living in zone six and below can ordinarily grow a hydrangea situated in full sun. Southern gardeners will have the best success growing their hydrangeas in afternoon shade. This protects the plants from the most intense sun exposure and gives you the most handsome display.

2 – Best hydrangeas for full sun
Out of the five most common hydrangeas – panicle, smooth, oakleaf, bigleaf, and mountain – you’ll have the best luck with panicle hydrangeas. They are the most sun tolerant.

3 – How to care for hydrangeas in full sun
Your biggest priority will be water. The two things that will help you give your plant the best care are a layer of mulch to increase water retention and a water meter to check the soil moisture before you give it a drink. There’s a common misconception that hydrangeas need to be practically drowning in water to thrive and that is just not the case. They like moist soil, but there absolutely needs to be oxygen in it for them to thrive. Check out this video on water meters if you’d like to learn more about knowing when to water.

  • PUGSTER BLUE® Butterfly Bush

    A smaller habit, but not smaller blooms. Pugster Blue® buddleia has the same impact as a full size plant, but with a much smaller footprint. You’ll love how its massive dark blue blooms (measuring up to six inches long) decorate the stocky habit. Each bloom pops up, almost like a firework. Its quirky habit cheers up the border, makes a fun low hedge, or integrates easily into a pollinator garden. After it’s established, it is extraordinarily drought tolerant and doesn’t need any deadheading to bloom from summer straight through to frost. You’ll only need to give it a quick trim in spring to encourage that vigorous new growth each season. Pugster Blue butterfly bush is a Blue Ribbon Winner for performance in the University of California low irrigation landscape trials.

I am all in when it comes to gardening. Almost every part of the experience delights me – new leaves emerging in spring, pollinators buzzing in summer, birds devouring berries in fall, and the somber beauty of seed heads in winter. Thanks to a background in horticulture and gardening my own clay-filled, flowery USDA zone 5b plot, I’ve learned plenty of practical things as well. I like sharing these joys and lessons with my fellow gardeners and soon-to-be gardeners any way I can.
