What to Look for When Growing Full Sun Hydrangea

Full sun hydrangeas are often hardy and generally require low maintenance. However, for successful hydrangea planting, there are some tips you should follow when growing hydrangeas in full sun. 

Which USDA Zone Are You In

From all locations listed above, it’s not hard to see most full sun hydrangeas thrive in 3-8 hardiness zones. 

If you are living in northern regions (zone 6 and below), growing hydrangeas in full sun should not be a problem even in hot summers. For indoor hydrangeas growing such as Bobo,  Fire Light, and Littlt Lamb, perhaps you’ll have to think about using plant grow lights in areas with limited natural sunlight, especially during the winter. 

On the other hand, for southern gardeners, the morning sunlight is all you need. And it would be a wise idea to provide afternoon shade to protect hydrangeas from intense sun exposure. 

Ample Watering Is A Must 

Except for certain varieties that are highly drought-tolerant, most hydrangeas in full sun will need more water to thrive. Keep the soil consistently moist, but not waterlogged. Use a soaker hose or drip irrigation to deliver water directly to the base of the plant and avoid wetting the leaves, as wet leaves in direct sun can lead to burn or disease.

Mulch Is Necessary 

Apply a layer of organic mulch, such as wood chips or compost, around the base of the plant. Mulch helps retain soil moisture, regulate soil temperature, and reduce weed competition.
