Seiju Elm – Ulmus parvifolia ‘Seiju’

Overview: Seiju Elm, scientifically known as Ulmus parvifolia ‘Seiju’, is a dwarf variety of the Chinese Elm. It is admired for its compact size, intricate branching, and small, glossy green leaves that turn a striking yellow in the fall. This hardy and versatile tree is ideal for bonsai, small gardens, and urban landscapes, where its elegant form and textured bark add year-round interest.

 

Typical Uses:

Seiju Elm serves various purposes in garden and landscape design:

• As a specimen plant in small gardens, patios, and courtyards, providing a focal point with its distinctive form
• In bonsai, appreciated for its miniature leaves, fine branching, and ease of shaping
• In urban landscapes and container gardens, offering a compact and resilient option for limited spaces
• In mixed borders and foundation plantings, adding structure and seasonal color

Establishment and Care Instructions:

Planting: Choose a site with well-drained soil and full sun to partial shade. Dig a hole twice as wide and as deep as the root ball. Place the tree in the hole, ensuring the top of the root ball is level with the soil surface. Backfill with soil and water thoroughly.

Watering: Water regularly during the first growing season to help the tree establish. Once established, Seiju Elm is drought-tolerant and only requires supplemental watering during prolonged dry periods.

Pruning: Prune in late winter or early spring to maintain the desired shape and remove any dead or crossing branches. Light pruning can be done throughout the year to refine its form.

Fertilizing: Apply a balanced fertilizer in spring to support healthy growth and foliage. Avoid excessive fertilization, which can lead to overly rapid growth that may detract from its form.
