Ilex crenata 'Convexa' is a versatile species that thrives in various locations, whether in sun, partial shade, or shade. It is an ideal choice for gardeners seeking a low-maintenance yet visually appealing hedge.

Key Features

Ilex crenata 'Convexa' is particularly resilient, with winter hardiness down to -23.3°C, suitable for USDA zone 6.
The species presents a moderate growth rate, allowing for a manageable maintenance schedule while still achieving a full hedge swiftly.
The evergreen nature of the Ilex ensures year-round foliage color, ranging from cream to yellow and green.

Tips

Optimal growth for Ilex crenata 'Convexa' occurs with regular watering, especially in well-drained soil. However, take care not to overwater, as this can be detrimental to the plant's health.
If shaping is desired, prune once a year to maintain its neat, hedge-like form. Pruning is best done after flowering to promote new growth and maintain the plant's dense, visual appeal.
Propagation can be successfully achieved with semi-ripe or hardwood cuttings, ensuring the continued beauty of the Japanese holly in your garden for years to come.

Ideal placement of a Ilex crenata 'Convexa'

The Ilex 'Convexa' thrives in a variety of lighting conditions, from full sun to partial shade and even full shade, making it a versatile choice for landscaping. It is adaptable to different soil types, provided they are well-drained. This species exhibits a robust winter hardiness, tolerating temperatures down to -17.8°C, aligning with USDA zone 6, ensuring its resilience in colder climates. For optimal growth and foliage vibrancy, selecting a location that meets these conditions is ideal.

How do I plant a Ilex crenata 'Convexa'?

This species thrives in a variety of locations, from full sun to shade, and is suitable for all well-drained soil types. Planting should be done with consideration for its mature size and its use as a hedge, ensuring adequate space for growth. The root system, being pot-grown, allows for flexibility in planting times. After planting, it is important to maintain consistent moisture levels in the soil to support establishment. Given its moderate growth rate of 15-30 cm per year and its capacity for winter hardiness down to -17.8°C, this evergreen maintains its visual appeal throughout the seasons.

Pruning a Ilex crenata 'Convexa'

To maintain a neat appearance for hedges crafted from Ilex crenata 'Convexa', minimal pruning is necessary, typically just once per year. It is best to perform this task after the flowering period, around late June or July. This timing encourages new growth while preserving the plant's delicate white blossoms. Thanks to its moderate growth rate, extensive cutting back is seldom required. For optimal health and shape, ensure the use of clean, sharp tools, which facilitates quick recovery and dense, lush foliage.

Watering a Ilex crenata 'Convexa'

To ensure the health and growth of Ilex crenata 'Convexa', consistent watering is crucial, particularly during its establishment phase and in times of drought, as it is not drought-resistant. During the growing season, the soil should be kept moist but not waterlogged. Over-watering can be as detrimental as under-watering, so it is important to check that the soil drains well. In winter, reduce the amount of water, but do not allow the root ball to dry out completely, especially since this evergreen retains its foliage and may still lose moisture on sunny or windy days.

Fertilising a Ilex crenata 'Convexa'

Fertilizing this species should be done with care to ensure the plant maintains its lush, evergreen appearance and supports its modest growth rate. Apply a balanced, slow-release fertilizer in early spring to encourage vibrant foliage and healthy development throughout the growing season. It's important to follow the manufacturer's instructions to avoid over-fertilization, which can lead to excessive growth and potential vulnerability to winter damage.

Given its winter hardiness, ranging from -17.8°C to -23.3°C, and corresponding to USDA zone 6, it's crucial to cease fertilizing by late summer to allow the Japanese holly 'Convexa' to harden off before the cold season. This timing helps ensure that the plant enters dormancy properly, fortified against the winter conditions.
