How to Grow Beautiful Oakleaf Hydrangeas
Grow beautiful oakleaf Hydrangeas in your yard with these planting tips. There are a variety of hydrangeas to choose from, many of which are derived from plants native to China, Japan, and nearby islands. However, one hydrangea is native to the US: the oakleaf hydrangea, which is native to the country’s southeastern area.
There are several dwarf and larger varieties of oakleaf hydrangeas. At maturity, dwarf oakleaf hydrangeas grow between 3 and 4 feet tall and wide, while the average mature size of most varieties is between 6 and 8 feet tall and wide. These stunning shrubs bloom from May to July, with white blooms turning to shades of pink and purple. The fall season sees leaves turn to purple, red, and bronze colors.
Plant dwarf-size varieties in a container or on the ground. Grow the taller varieties in the ground. Plant larger varieties in mass for a dramatic impact. A deciduous shrub that loses its leaves in the fall is hardy up to zone 5. Grow Oakleaf Hydrangeas in full sun in colder climates. In warmer climates, grow oakleaf hydrangeas in the shade to avoid the sun’s intensity.
Characteristics of Oakleaf Hydrangeas
This variety of hydrangeas has a compact, upright-mounting shape. A free branch habit with solid stems. The branches support the panicle, which blooms upright without any hanging downward. Exceptionally hardy, thriving in zones up to x.
First, the characteristics of the Little Lime Hydrangea shrub:
- Grows in zones x to x
- Plant in full Sun to partial shade
- At maturity, it reaches between 3 to 5 feet high with 3 to 5 feet spread

- Flowers are upright, sharply-pointed conical panicles growing 6 to 8 inches long
- Bloom from early summer to late summer
- Foliage leaves are green
- Water needs are average, so water regularly
- Grows best in organically rich soil conditions that drain well; avoid clay soil
- The growth rate is average
Remember, plants thrive in full sun with six or more hours of sun. Plants with partial sun requirements thrive for 4 to 6 hours daily. Meanwhile, full-shade plants need up to 4 hours daily.
Conditions for Growing Healthy Oakleaf Hydrangeas
Give your Oakleaf Hydrangea a leg up by providing the best-growing conditions—plant in the ground with well-draining soil. Organically rich soil is best. Water this shrub with an average amount of water to keep it moist.
Avoid dense soil that retains water, such as clay soil. An easy way to test your soil is to grab a handful and close your hand. Then, open your hand and examine the soil. If the soil stays compressed and remains in a clump, it is clay. If the soil is loose and quickly falls apart, it is organic and well-draining.
Organic soil has better drainage capabilities. Oakleaf hydrangeas do not like wet, soggy soil. Clay soil traps water and forms puddles. The water needs to drain away from the Oakleaf Hydrangea’s root system.
Ground Soil Preparation for Oakleaf Hydrangeas
Use these helpful tips to grow little lime hydrangeas for maximum curb appeal.
- Select a garden space with full sun or partially shaded based on your location.
- Prepare the soil by digging a hole twice the depth and width of your shrub.
- Add compost or rich organic soil and sphagnum peat moss to the soil (for best results, use 1/3 of your ground soil, 1/3 compost, and 1/3 sphagnum peat moss)
- Work the soil thoroughly so the soil and amendments are mixed well. This is essential to ensure that soil drains quickly.
- Potting soil and garden soil should release excess water quickly – this is necessary for hydrangeas to thrive.
- Sprinkle a handful of organic milky spore powder on the soil if grubs or Japanese Beetles are a problem. Follow the manufacturer’s instructions.

Fertilize during the spring using a slow-releasing fertilizer such as Holly Tone per the manufacturer’s directions.
Fall or Spring Pruning

Origination of Oakleaf Hydrangea
A newer introduction, Little Lime, was developed during a breeding program in Grand Haven, Michigan, in 2005. It started with a limelight hydrangea that was crossed with other hydrangea paniculatas, and then the little lime was born.
The original limelight, a woody shrub, is a cultivar of panicle hydrangea. The parent plant is native to eastern and southern China, Japan, and the Islands of Sakhalin and Kuril.
