Origin
Philonotis calcarea (Bruch & Schimp. in B.S.G.) Schimp. f. occidentalis is a species of moss native to North America. It is commonly found in the western regions of the United States, including California, Oregon, and Washington.
Common Names
Philonotis calcarea is commonly known as Limestone Fern Moss, Limestone Willow Moss, or Cave Moss due to its preference for growing on calcareous rocks and its resemblance to ferns and willows.
Uses
Philonotis calcarea is primarily used for its aesthetic value in landscaping. Its unique appearance makes it an attractive addition to rock gardens, water features, and as a ground cover. In addition, it has been used in the past for medicinal purposes, such as treating wounds and muscle pain.
General Appearance
Philonotis calcarea is a small moss that forms compact, dense cushions on limestone rocks. Its stems are upright and can reach up to 3 cm in length. The leaves are narrow and taper to a point, giving them the appearance of fern fronds or willow leaves. The leaves are also arranged in a spiral pattern around the stems. The capsules that hold the spores are small and round, held on short stalks that rise above the leaves. The overall appearance of Philonotis calcarea is delicate and graceful, making it a striking addition to any landscape.
Growth Conditions of Philonotis Calcarea
Philonotis calcarea (Bruch & Schimp. in B.S.G.) Schimp. f. occidentalis is a species of moss that commonly grows in moist habitats. It is found in a variety of environments like bogs, fens, wet meadows, and forested stream banks. Here are some of the typical growth conditions required for its development:
Light
Philonotis calcarea prefers growing in shaded areas because direct sunlight can cause desiccation and mortality of the plants. It can tolerate a range of light intensities from low to moderate light, and it usually grows under the canopy of trees or in shaded areas near streams. If the moss is grown in areas of high light intensity, it's essential to provide shading to prevent mortality and ensure optimal growth.
Temperature
The optimal temperature range for Philonotis calcarea growth is between 10-20°C, and it can tolerate temperatures as low as -4°C and as high as 25°C. The moss can grow in cold habitats and can tolerate freezing temperatures for some time. However, extended periods of freezing can cause mortality or reduce the growth rate. It's essential to maintain the temperatures within the optimum range to ensure healthy growth and development of the moss.
Soil Requirements
Philonotis calcarea grows on a range of substrate types, including acidic and alkaline soils. However, it mainly grows in wet soils with neutral to slightly acidic pH. The soil should be moist and retain water to support the growth of the moss. The presence of organic matter like leaf litter and decaying plant materials provides the ideal substrate for the development of the moss. Additionally, adequate drainage is necessary to prevent waterlogging, which can cause mortality of the moss.
Overall, Philonotis calcarea requires proper growing conditions to thrive and develop optimally. These conditions include moderate light intensity, temperature within the optimum range, and moist, well-drained soils with neutral to slightly acidic pH and organic matter content.
Cultivation methods
Philonotis calcarea is a small, nonvascular plant that does well in a well-draining substrate. It requires bright, indirect light to grow well and can be propagated by division or cuttings. It is best grown in a terrarium or enclosed container, where humidity levels can be controlled.Watering needs
The plant requires consistently moist growing conditions, with the substrate remaining damp but not waterlogged. Water the plant deeply once a week or more frequently if the surrounding environment is warm and dry. Always water the plant from the bottom, allowing the substrate to soak up the water. Avoid watering the plant from the top as it can cause water to pool on the leaves, increasing the risk of rot.Fertilization
Philonotis calcarea is a low-maintenance plant that doesn't require regular fertilization. However, you can feed the plant with a weak, balanced liquid fertilizer once every two to three months during the active growing season. Alternatively, work a slow-release fertilizer into the substrate before planting or top-dress the substrate with compost.Pruning
Since it is a small plant, Philonotis calcarea doesn't require pruning. However, you can remove any damaged or discolored leaves to keep the plant looking neat and tidy. Take care not to damage the stems and leaves during pruning as the plant is delicate and can break easily. Use clean and sharp pruning shears to make clean cuts and prevent the spread of disease.Propagation of Philonotis Calcarea Schimp. f. Occidentalis
Philonotis calcarea (Bruch & Schimp. in B.S.G.) Schimp. f. occidentalis is a tufted, mat-forming plant that belongs to the family Bartramiaceae. The plant is native to North America and grows in wet, calcareous habitats such as stream banks, seeps, and wet meadows. The propagation of Philonotis calcarea Schimp. f. occidentalis can be done by various methods.
Propagation by Spores
Philonotis calcarea Schimp. f. occidentalis reproduces sexually through spores. The spores are produced in spherical capsules known as sporangia, which are located at the tips of the plant's stems. When the capsules mature, they burst open to release the spores. To propagate Philonotis calcarea Schimp. f. occidentalis by spores, the sporangia must be collected and placed in a container with damp soil. The spores will then germinate into small, thread-like structures known as protonemata. The protonemata will eventually develop into mature plants.
Propagation by Division
Philonotis calcarea Schimp. f. occidentalis can also be propagated asexually through division. This method involves dividing the plant into smaller sections and planting them in separate containers or areas. To propagate Philonotis calcarea Schimp. f. occidentalis by division, the plant must be carefully uprooted and separated into smaller sections. Each section should have several stems and some root mass. The sections can then be planted in containers or areas with suitable soil and watered regularly until they establish themselves.
Propagation by Cuttings
Propagation of Philonotis calcarea Schimp. f. occidentalis can also be done by taking stem cuttings. This method involves taking a piece of stem with a node and planting it in a container or area with suitable soil. The stem should be placed in a vertical position and watered regularly until it establishes itself. Over time, the stem will develop roots and grow into a mature plant.
Disease and Pest Management for Philonotis calcarea
Philonotis calcarea (Bruch & Schimp. in B.S.G.) Schimp. f. occidentalis is a type of moss that can develop some diseases and pests over time. In this section, we will discuss the common diseases and pests that might affect the plant and suggest ways to manage them.
Common Diseases of Philonotis calcarea
The common diseases of Philonotis calcarea include:
1. Brown patches: These indicate the presence of fungal disease. To manage this, remove the affected parts of the plant and ensure that the moss is not overwatered. 2. Yellowing: This could be a symptom of nutrient deficiency or overexposure to sunlight. To prevent this, ensure that the plant is well-fed and placed in a partially shaded area. 3. Dryness: This happens when the moss doesn't receive enough water. To prevent this, ensure the moss is watered enough, especially during hot and dry seasons.Common Pests of Philonotis calcarea
The common pests that infest Philonotis calcarea include:
1. Aphids: These are small insects that suck the sap from the plant, leading to stunted growth. To control aphids, spray the plant with water and insecticidal soap. 2. Spider Mites: These are tiny pests that are barely visible to the naked eye. They also suck the sap of the plant, leading to wilting and yellowing leaves. Control spider mites by washing the plant with water and using insecticidal soap. 3. Snails and slugs: These pests feed on the leaves of the moss, leading to significant damage. Control snails and slugs by handpicking them or by using snail baits.
