Water
The Dwarf Blue Lawson Cypress should be consistently watered to maintain moist soil, especially during its first growing season to establish a deep and extensive root system. After establishment, it can tolerate less frequent watering, but itβs important to avoid letting the soil dry out completely. During the growing season, water this conifer about once a week with approximately 1 to 2 gallons of water per session, depending on the size of the plant and the weather conditions. Keep a closer eye on watering during hot, dry spells, as the plant may require additional water to prevent stress.
Light
The Dwarf Blue Lawson Cypress thrives best in full to partial sunlight. It should be placed in a spot where it can receive at least 6 hours of direct sunlight each day. An ideal location would be in a garden area that is exposed to morning sunlight and receives some afternoon shade, especially in hotter climates, to protect the plant from scorching.
Temperature
The Dwarf Blue Lawson Cypress prefers cool to moderate temperatures and is hardy in a range from 20 to 70 degrees Fahrenheit, though it can tolerate temperatures slightly below this range. Avoid placing it in locations where the temperature can drop below -10 degrees Fahrenheit, as extreme cold can damage the plant. The ideal temperature for this conifer is between 40 and 60 degrees Fahrenheit.
Pruning
Prune the Dwarf Blue Lawson Cypress to maintain its shape or to remove any dead or damaged branches. Pruning should be done in the late winter or early spring before new growth starts. This plant doesn't require frequent pruning; once a year is typically sufficient. When pruning, make gentle cuts and avoid cutting back into old wood as it may not regenerate.
Cleaning
As needed
Soil
The best soil mix for the Port Orford cedar is well-draining, acidic to neutral in pH (around pH 5.0-7.0). A mixture containing peat moss, perlite, and organic compost is suitable for promoting healthy growth and preventing root rot.
Repotting
Port Orford cedar, being a slow-growing conifer, typically needs repotting every 2 to 3 years to ensure it's not pot-bound and to refresh its soil.
Humidity & Misting
Port Orford cedar thrives in moderate to high humidity levels; above 50% is ideal for this plant. It is important to maintain consistent humidity without fluctuations.
Suitable locations
Indoor
Place in well-lit area, avoid dry heat and direct sun.
Outdoor
Provide full sun, shelter from harsh winds, ensure well-drained soil.
Hardiness zone
5-8 USDA
Life cycle
The Lawson's Cypress 'Minima Glauca' begins its life as a seed, which, after germination, grows into a small seedling characterized by its bright green, needle-like foliage. It then enters a juvenile phase, where growth rates are rapid, and the plant progressively develops the blue-gray, scale-like leaves for which this cultivar is known. As it matures, the Lawson's Cypress 'Minima Glauca' reaches maturity, developing a compact, conical form with dense branching and foliage, a phase that can last for several decades. During its reproductive phase, it produces small, inconspicuous cones that mature and release seeds, completing the cycle. The plant exhibits slow growth throughout its life, requiring minimal pruning and maintenance. Eventually, as the Lawson's Cypress 'Minima Glauca' reaches its later years, growth slows further and it may succumb to environmental factors, pests, or diseases, leading to its decline and end of life cycle.
Propogation
Propogation time
Late Winter to Early Spring
The most popular method of propagating the Chamaecyparis lawsoniana 'Minima Glauca', commonly known as Miniature Blue Lawson Cypress, is through semi-hardwood cuttings. This typically occurs in late summer to early autumn, when the current year's growth has matured enough to slightly harden but still retain some flexibility. Cuttings of about 4 to 6 inches (10 to 15 centimeters) long are taken, with the lower leaves removed to expose a clear stem. The cut end can be dipped in rooting hormone to enhance root development before being placed into a soilless potting mix or perlite. The environment should be kept humid, and the soil consistently moist, but not waterlogged, until roots are established, which usually takes a few months. Once rooted, the young plants can be gradually acclimatized to less humid conditions before being transplanted outdoors.
