Dwarf Plume Cypress Chamaecyparis pisifera 'Plumosa Compressa'

Water

For the Dwarf Japanese Cedar (Chamaecyparis pisifera 'Plumosa Compressa'), water the plant deeply and thoroughly to ensure that the root zone is moist. This may require several gallons per watering, depending on the size of the plant and the environmental conditions. During the growing season in spring and summer, watering may be necessary once a week, especially in the absence of rain. In the fall and winter, reduce watering but do not allow the soil to completely dry out. It is important to adjust the frequency based on rainfall, temperature, and humidity, as overwatering can lead to root rot.

Light

The Dwarf Japanese Cedar prefers full sun to partial shade for optimal growth. The best spot would be one that receives a minimum of 4 to 6 hours of direct sunlight daily, with some protection from the intense afternoon sun if possible. Avoid placing it in deep shade or overly dark locations, as this can limit its growth and result in a less dense foliage.

Temperature

The Dwarf Japanese Cedar thrives in temperatures ranging from 50°F to 70°F and is hardy in temperatures as low as -30°F and as high as 90°F. However, it is ideal to avoid sudden temperature fluctuations and to maintain a consistent environment. These trees are generally tolerant of a wide range of temperatures once established, but young plants should be protected from extreme cold and heat.

Pruning

Pruning the Dwarf Japanese Cedar is generally done to maintain its desired shape or to remove any dead or diseased branches. Light pruning can be carried out in late winter or early spring before new growth starts. It is not necessary to prune the plant frequently; once a year or even less often should suffice unless shaping is desired. Always use clean, sharp tools to make precise cuts and avoid heavy pruning which can harm the plant.

Cleaning

As needed

Soil

The best soil mix for the Moss Cypress should be well-draining and have a slightly acidic to neutral pH, ideally between 5.0 and 7.0. A mix of 1 part peat, 1 part pine bark, and 1 part coarse sand or perlite is recommended for optimal growth and health.

Repotting

Moss Cypress typically requires repotting every 2 to 3 years. Choose a pot just one size larger to prevent overwatering issues and refresh the soil mix during each repotting to maintain nutrient levels.

Humidity & Misting

Moss Cypress thrives in moderate humidity levels around 40-50%. These conditions are often met in outdoor environments, but in very dry climates, misting the plant may be beneficial.

Suitable locations

• Indoor

  Provide bright light and good air circulation for indoor Moss Cypress.

• Outdoor

  Plant in full sun to part shade, shelter from harsh winds for outdoor Moss Cypress.

• Hardiness zone

  4-8 USDA

Life cycle

The life cycle of the Japanese False Cypress 'Plumosa Compressa' starts with seed germination, typically requiring stratification or a period of cold to break dormancy. After germination, the seedling stage is characterized by initial root and shoot development. As it enters the juvenile phase, the plant's foliage begins to display the characteristic dense, 'plumosa' or feather-like foliage, and it starts to take on its dwarf, compact shrub form. In the mature phase, the Japanese False Cypress 'Plumosa Compressa' may produce small, round cones if conditions are suitable for sexual reproduction, although this is often rare in cultivated varieties. The plant then continues to grow slowly, maintaining its shape with minimal pruning, and can live for many years if provided with appropriate care. As it ages, the plant may become more susceptible to environmental stresses and pests, eventually reaching the end of its life cycle when its vital functions cease.

Propogation

  Spring-Early Summer

• The most popular method of propagating the Chamaecyparis pisifera 'Plumosa Compressa', commonly known as the Moss Cypress, is through semi-hardwood cuttings. This is typically done in the late summer to early fall when the current year's growth has started to harden but is not yet fully mature. Cuttings should be about 4 to 6 inches (10 to 15 centimeters) long and include several nodes. Strip the lower leaves to expose the nodes and dip the cut end into a rooting hormone powder to enhance root development. Then, plant the cuttings in a well-draining potting mix and keep them moist and in high humidity. The cuttings should root within a few weeks to a couple of months, after which they can be gradually acclimated to outdoor conditions and eventually transplanted into the landscape.
