Long-stalk holly (Ilex pedunculosa)

Also known as: Longstalk Holly, Tsuru-tsuge

The leaves are 1 to 2 cm in length, with elongated petioles. They grow in an alternate pattern and are oval-shaped, with a slightly leathery and glossy texture, giving them a generous appearance. The upper surface is dark green and smooth, while the underside is lighter, with a prominent midrib. The edges are smooth but exhibit a wavy form. The tree can reach heights of 3 to 7 meters. It flowers in spring to summer, with separate male and female flowers. Female flowers appear individually in the leaf axils, while male flowers are clustered into small white inflorescences. The fruit, which ripens to a red color in fall, is spherical, about 7 mm in diameter, and hangs on a 5 to 6 cm stalk.

What Is the Ideal Temperature Range for Long-stalk holly?

Ideal Temperature: 60 ~ 75℉

Ilex pedunculosa thrives best in a temperature range from 60°F to 75°F. This ensures optimal photosynthesis and prevents stress, leading to robust growth and vibrant foliage. It is recommended to maintain this temperature range to support healthy growth cycles throughout the year.

What Soil is Best for Long-stalk holly?

Soil type: Loam, Acidic soil

Soil PH: 6.5 ~ 7.5

Ilex pedunculosa thrives in soil conditions that offer excellent drainage. This ensures that the roots maintain optimal moisture levels, preventing root rot and allowing the plant to absorb nutrients more effectively. The plant prefers soil that is rich in organic matter. Such substrates provide essential nutrients that promote vigorous growth and maintain vibrant foliage across different seasons. While it needs well-drained soil, Ilex pedunculosa also requires soil with good moisture retention ability to maintain consistent hydration and support its lush greenery.

How to Fertilize Long-stalk holly?

Fertilizer type: Balanced

Ilex pedunculosa has moderate nutrient needs. When applying liquid fertilizer, use a balanced formula diluted to half strength, such as 10-10-10, and apply about 500ml per plant. For slow-release fertilizer, use approximately 50 grams per plant, adjusted based on plant size.

How to Prune Long-stalk holly?

Pruning Time: Spring, Summer, Autumn

Begin by assessing the overall shape and health of the Ilex pedunculosa. Identify any dead or diseased wood that needs to be removed to promote better airflow and sunlight penetration. Start by cutting away any dead branches using sterilized shears. Focus on branches that cross each other, as they can cause wounds and lead to disease. Finish by trimming back any growth that detracts from the desired shape. Aim for a natural look, avoiding harsh cuts. Step back regularly to check the plant's shape.

How to Propagate Long-stalk holly plant?

Propagate Time: Spring, Late spring, Early summer

If propagating via seeds, collect the holly's berries when they are mature. Clean the seeds carefully to remove all pulp, as the pulp can inhibit germination.

For cuttings, choose a healthy branch of about 4-6 inches in length. Cut just below a node, and remove the lower leaves without damaging the stem.

To propagate by layering, select a low branch and bend it to the ground. Make a small wound on the branch before covering it with soil, ensuring it is watered regularly to promote root growth.

How to Repot Long-stalk holly plant?

Repotting frequency: Every two years

Repot Ilex pedunculosa when you notice roots emerging from the drainage holes or when growth appears stagnant. Spring is ideal as the plant is transitioning into active growth, making it more resilient to the stress of repotting.

Select a pot that is 2-3 inches wider than the current one with adequate drainage holes. A slightly larger pot prevents waterlogging and encourages root expansion, promoting healthier growth and minimizing the risk of rot.

Use a well-draining acidic soil mix, rich in organic matter. Such a mix mimics the plant's natural habitat, ensuring healthy root development and access to crucial nutrients while preventing water from pooling at the roots.
