Sequoia sempervirensAdpressa‘ and ‘Albospica’ represent two fascinating expressions of the same genetic variation, with ‘Albospica’ being the upright, tree form and ‘Adpressa’ developing as a more compact version. Both cultivars showcase distinctive tight, dense foliage that sets them apart from typical Coast Redwoods.

Adpressa‘, the more compact form, responds exceptionally well to pruning and can be maintained as a tight, bright white ball through regular shearing. Without pruning, it develops into an open, broadly conical specimen reaching 1.5-2m tall after 10 years. For best results, young specimens should be staked to maintain a straight trunk, particularly if a more formal appearance is desired.

Albospica‘ develops as a broadly conical tree, maintaining a more refined and formal appearance than the species. Its needles are notably compressed and tightly packed, creating an elegant, dense appearance that brings sophistication to the garden landscape. This upright form embodies the majestic qualities of Coast Redwood while remaining manageable in scale.

These cultivars demonstrate remarkable adaptability to urban gardens and smaller spaces, offering the presence of a Coast Redwood in a more contained form. Their dense growth habits create excellent focal points, while their manageable size makes them suitable for contemporary garden designs where space might be limited.

Whether grown as specimens or incorporated into formal gardens, both forms bring unique character to the landscape. Their compact growth and distinctive foliage make them particularly valuable for gardeners seeking the essence of Coast Redwood without requiring extensive space.

Position in full sun or partial shade. Ensure well-draining soil conditions. Regular staking of young specimens is recommended to maintain straight growth. For ‘Adpressa’, implement regular shearing if a formal ball shape is desired. Water consistently during establishment. Apply an annual spring mulch to maintain soil moisture and suppress weed growth.

Coast Redwood – Sequoia sempervirens Care Guide

The Coast Redwood – Sequoia sempervirens is one of the world’s most magnificent trees, capable of reaching extraordinary heights in its native California. In UK gardens, while not achieving the same dramatic proportions, it still grows into an impressive specimen, typically reaching 20-35 metres. This evergreen conifer is characterised by its straight trunk, distinctive reddish-brown bark, and dense, dark green foliage that creates a stunning vertical accent in larger gardens. Despite its imposing stature, it’s surprisingly adaptable to UK conditions when given appropriate care.

Soil Requirements
Coast Redwoods thrive in well-draining, fertile soil with a pH between 5.5 and 7.0. While they prefer deep, loamy soils rich in organic matter, they can adapt to various soil types provided drainage is adequate. Regular addition of organic matter helps maintain soil quality and moisture retention, which is crucial for optimal growth.

Watering Guidelines
Young trees need consistent moisture during their establishment period, typically the first 2-3 years. Water deeply once weekly, adjusting for rainfall and temperature. While mature specimens develop some drought tolerance, they perform best with regular moisture, particularly during dry spells. Container-grown trees require more frequent watering, but always ensure pots have adequate drainage to prevent waterlogging.

Seasonal Maintenance

Spring (March-May)
Apply a balanced, slow-release fertiliser if needed, and refresh the organic mulch layer to a depth of 7-10cm, keeping it clear of the trunk. Check for any winter damage and monitor for early signs of pest activity.

Summer (June-August)
Maintain consistent soil moisture, especially during hot, dry periods. Minimal pruning is required, but remove any dead or damaged branches. Ensure the base remains clear of competing vegetation.

Autumn (September-November)
Gradually reduce watering as growth slows. Apply a fresh layer of mulch to protect roots through winter. This is a good time to assess the tree’s structure and plan any necessary maintenance.

Winter (December-February)
Young trees may need protection from severe frost and cold winds. Water only during dry spells when there’s no frost. Monitor for snow damage on branches, particularly in heavy snowfall areas.

Additional Care Notes
Coast Redwoods create their own microclimate as they mature, often collecting moisture from fog and mist through their foliage. They prefer locations with some shelter from strong winds, especially when young. While generally pest-resistant, regular monitoring helps catch any issues early.

These magnificent trees require careful placement due to their potential size. Consider their ultimate height and spread when planting, ensuring they have space to develop their natural form. While they can be pruned to control size to some extent, they’re best suited to larger gardens where they can achieve their natural grandeur. Their evergreen nature means they provide year-round interest and can serve as excellent screening trees or distinctive focal points in appropriate settings.
