When it comes to garden plants, the oakleaf hydrangea is a popular choice. It is a deciduous shrub that is native to the southeastern United States, and it is prized for its large, showy white flowers and deep green foliage. It is also easy to care for and can thrive in a variety of climates. Here are some tips on how to grow and care for an oakleaf hydrangea.
Location
Oakleaf hydrangeas are best suited to full sun and partial shade. They prefer well-drained soil and will tolerate a wide range of soil pH levels. If your soil is clayey, consider adding some organic matter or compost to improve drainage.
Planting
When planting an oakleaf hydrangea, it is important to dig a hole that is twice as wide as the root ball and just as deep. This will allow the roots to spread out and establish themselves more easily. When planting, make sure to spread the roots out in the hole and fill in with soil.
Watering
Oakleaf hydrangeas should be watered regularly during the growing season. They prefer moist but not soggy soil, so water deeply and allow the soil to dry out between watering. During the winter, the plant will require less water.
Fertilizing
Oakleaf hydrangeas should be fertilized twice a year, in the spring and fall. A balanced fertilizer is recommended, such as a 10-10-10 or 20-20-20. Make sure to follow the package instructions for the correct application rate.
Pruning
Pruning is not necessary for oakleaf hydrangeas, but it can be done to shape and control the size of the plant. Prune in the spring just before new growth begins. Make sure to use sharp pruners and cut at an angle.
Diseases and Pests
Oakleaf hydrangeas are generally resistant to most diseases and pests. However, they can be susceptible to fungal diseases such as powdery mildew and leaf spot. If you notice any signs of disease, treat the plant with a fungicide.
