Korean Thuja ‘Glauca’

Korean Thuja ‘Glauca’ (Thuja koraiensis ‘Glauca’). Thuja koraiensis ‘Glauca’, commonly known as Korean Thuja ‘Glauca’, is an evergreen conifer with an elegant, broad conical habit, prized for its distinctive blue-green foliage. Its flattened branches have a bluish-green upper surface and a distinct silvery underside, creating a luminous and contrasting effect with the slightest breeze. Its fine texture and naturally structured silhouette make it an excellent choice as a specimen plant, in conifer beds, or as a decorative screen. More tolerant of intense cold than some other thuja species, it adapts to cool, well-drained, and slightly acidic soils.

To plant Korean Thuja ‘Glauca’, choose a suitable exposure: sun to partial shade. The recommended soil is cool, well-drained, and slightly acidic. Respect the conifer's natural shape and avoid cutting deeply into parts without foliage. Monitor moisture after planting, including in autumn when the weather is dry. Aeration and drainage are as important as watering frequency. Water the root ball before planting and ensure water can drain after planting. During establishment, check the moisture by hand before watering again.

Allow for a width of 3 m (10 ft) when planning the plant's space in the garden. The indicated height of 5 m (16 ft) helps choose its position relative to neighboring plants. Keep access to the base for weeding, checking moisture, and removing damaged parts. Combine this variety with plants that have compatible light and water needs. If you are considering a container, first check that its volume and drainage are suitable for root development. Roots in pots are more exposed to cold than those planted in the ground.
