It does best, however, in slightly acidic to neutral soils rich in organic matter. Amended soils are especially important in hot summer regions where the Oakleaf Hydrangea's shallow root system tends to dry out quickly.

The temperature condition is the most important factor in determining which oakleaf hydrangea variety is best for your garden. If you live in an area with hot summers, choose a variety that is heat tolerant. If you live in an area with cold winters, choose a variety that is cold hardy.
Ideal humidity condition for this plant is 50%. It can tolerant lower and higher humidity level but not for long time. If the humidity is too low, the leaves will dry out and drop off. If the humidity is too high, the leaves will develop brown spots.
About fertilizer, this type of plant responds well to organic compost and mulching. A root booster can also be added to the soil to help the plant establish itself.

Pruning is one of the most important tasks when it comes to taking care of your oakleaf hydrangea. By pruning, you can encourage new growth, prevent the plant from becoming overgrown, and manage its shape. There are a few things to keep in mind when pruning your oakleaf hydrangea. First, you'll want to prune in early spring, before new growth begins. This will ensure that you don't damage any new growth. Second, you'll want to cut back the stems by about one-third to encourage new growth. And finally, you'll want to make sure that you don't prune too much, as this can damage the plant.

Propagation of oakleaf hydrangeas is most commonly done through rooting stem cuttings taken from the tips of new growth in late spring or early summer. Cuttings should be 4-6 inches long and taken from healthy, new growth that has not flowered yet. Remove the bottom leaves and stick the cuttings into moistened potting mix or perlite. Cover the pot with a clear plastic bag to create a mini greenhouse and place in a bright spot out of direct sunlight. Keep the soil moist but not soggy and within a few weeks, roots should form and new growth will appear. Once the new plants are established, they can be transplanted into the garden.
Usually, the plant growth rate is rather fast, especially when compared to other shrubs. They can easily add 2 to 3 feet in height every year until they reach their full adult size. Some varieties may even grow a bit faster than this. Given the opportunity and proper care, oakleaf hydrangeas can live for decades and continue to produce an abundance of beautiful flowers each year.
Common problems for this kind of plant are fungal diseases, particularly leaf spot and powdery mildew. These problems are more likely to occur in humid conditions or when the foliage is wet. Good air circulation and avoiding overhead watering can help to prevent these problems. If they do occur, the affected leaves can be removed and the plants treated with a fungicide.
