The Oakleaf (sometimes incorrectly spelled with two words: Oak Leaf) Hydrangea comes in single- and double-blossom ("Snowflake") varieties, the latter being the more popular one. The Oakleaf Hydrangea is far easier to grow than other hydrangea species due to its ability to tolerate a wider range of environmental conditions, particularly cold and dryness. Oakleaf Hydrangeas thrive in sandy, drier soils and can survive cold winters with the right care. In addition to being easy to grow and care for, the Oakleaf Hydrangea is a gorgeous feature for any yard or landscape.
Plant your Oakleaf Hydrangea in well-drained soil that stays drier most of the time. The Oakleaf variety of hydrangea is much more sensitive to soggy conditions and more readily develops root rot. Sandy soil is best, but you can amend your soil with sand if necessary.
Position your Oakleaf Hydrangea plant in partial sunlight, preferably a sunny location that receives shade in the afternoon. The direct sunlight during most of the day will ensure that its leaves will change into vibrant colors in the autumn.
Water your Oakleaf Hydrangea sparingly, allowing it to remain lightly moist. Oakleaf Hydrangeas enjoy drier and hotter conditions in the summer than other hydrangea species.
Cover your Oakleaf Hydrangea with a sheet in the winter if your area experiences severe cold weather. If the plant is exposed to extreme cold, the terminal buds will die and the plant won't bloom the next season.
Prune the Oakleaf Hydrangea in the summer, right after the plant is finished flowering. Using pruning shears, remove all the old flowering shoots down to the new growth in the stem.
