How and when to plant Ilex (holly)
Ilex, commonly known as holly, is an evergreen shrub or tree highly valued for its glossy foliage and bright red berries that appear in autumn and winter. It is widely used for hedging, but also makes an impressive standalone plant with strong decorative value. When planted correctly, holly can live for many years and provide year-round beauty in the garden.
When is the best time to plant Ilex?
The best time to plant Ilex is in spring (March–April) or autumn (September–October). These periods provide mild temperatures and adequate soil moisture, helping the roots establish well before winter cold or summer heat.
Where to plant Ilex
Ilex prefers semi-shaded positions but will also tolerate full sun as long as the soil remains moist. The soil should be well-drained, rich in organic matter and preferably slightly acidic. Avoid areas with standing water. For decorative berries, both male and female plants need to be grown, as Ilex is a dioecious species.
How to plant Ilex step by step
- Dig a hole twice as wide as the root ball.
- Place the plant so that the top of the root ball is level with the soil surface.
- Backfill with garden soil mixed with compost or acidic peat.
- Firm the soil gently and water thoroughly after planting.
Aftercare
- Water regularly during the first year, especially in dry periods.
- Apply mulch to retain soil moisture and protect the roots.
- Prune lightly in spring or summer to maintain the desired shape.
- Protect young plants from severe frost in harsh winters.
Summary
Ilex is best planted in spring or autumn, in a semi-shaded location with well-drained, humus-rich soil. With proper planting and minimal care, this evergreen shrub or tree will provide structure, colour and ornamental interest to your garden throughout the year.
