How to grow and care for Hydrangea integrifolia


It thrives best from bright, indirect sunlight to partial shade. Provide at least 4 hours of bright, indirect sunlight every day.


It grows well in well-drained, peat-based soil with adequate amounts of organic matter, such as compost, leaf mold, or well-composted manure. While most hydrangeas grow better in soil that is lower in pH (acidic), they will tolerate higher pH soils (alkaline) quite well.


Water regularly during the growing season. Keep the soil evenly moist, but not soggy. Keep the soil barely moist in winter.


It prefers to grow at a temperature below 60°F/16°C. Keep your hydrangea plant as cool as possible to prolong the flowering time.


Fertilize every two weeks during spring and summer with a balanced liquid fertilizer (such as 10-10-10) diluted by half. Or, use a slow-release fertilizer once in spring and again in summer.


Hydrangea integrifolia can be easily propagated by stem tip cuttings. Take 4-inch stem tip cuttings in spring or early summer and root them in a moist potting mix.
