How do I plant a Ilex crenata 'Dark Green'?

To ensure successful establishment, plant Ilex crenata 'Dark Green' with its root ball during the dormant season, preferably in autumn or early spring. Begin by digging a trench that's twice the width of the root ball and equal in depth, allowing for adequate root expansion. Position the hedge plants in the trench, carefully spacing them to create a continuous, moderately obscuring screen. Backfill with a mixture of native soil and compost to promote healthy growth. Water thoroughly after planting to settle the soil around the root balls and to encourage the roots to stretch out into the surrounding earth.

Pruning a Ilex crenata 'Dark Green'

Pruning of Ilex crenata 'Dark Green' is an uncomplicated affair, as it maintains its shape with minimal intervention. To encourage denser foliage, a light pruning once a year suffices. Ideally, this should be carried out in late spring, after the plant has flowered, to shape the hedge and promote new growth. As an evergreen species, it retains its lush green leaves throughout the seasons, ensuring a consistent visual barrier. With its moderate growth rate, periodic trimming can maintain its desired size and form.

Watering a Ilex crenata 'Dark Green'

Ilex crenata 'Dark Green' thrives when provided with consistent moisture, particularly during its establishment phase. This species is not drought-resistant, hence regular watering is crucial in periods of low rainfall to maintain its lush green foliage. Overwatering or poor drainage can be detrimental, so ensure the soil is well-drained. During the growing season, keep the soil evenly moist but not saturated. As an evergreen hedge, even during the colder months, it requires attention to its hydration needs to protect it from desiccation, especially in areas experiencing winter winds.

Fertilising a Ilex crenata 'Dark Green'

To ensure the Ilex crenata 'Dark Green' thrives, fertilization is a key aspect of its care. Apply a balanced fertilizer designed for evergreens in early spring to kickstart the growing season. This species is not demanding, but providing nutrients can enhance its lush, green foliage and support its moderate growth rate. Additionally, a second application of fertilizer can be beneficial in late summer, promoting vitality as the plant prepares for the colder months. When applying fertilizer, distribute it evenly around the base of the Ilex 'Dark Green', avoiding direct contact with the foliage and stems to prevent any potential damage. With proper fertilization, this evergreen will maintain its visual density and robust health throughout the year.
