Leskeella tectorum (Funck ex Brid.) Hag. ssp. cyrtophylla (Kindb. in Mac. & Kindb.) Wijk & Marg. is a type of moss commonly known as the Common Wall Screw-moss. It belongs to the family Leskeaceae and is found in many parts of the world including eastern North America, Europe, and Asia. This species was first described by Funck ex Brid. under the Genus Grimmia in 1801, but was later reclassified under the Genus Leskeella by Wijk and Margadant in 1949.
General Appearance of the Common Wall Screw-moss
The Common Wall Screw-moss is small and typically grows in dense tufts that measure up to 2 cm in height. The plant has a branching structure with numerous short, erect stems that bear leaves. The leaves are tiny and narrow with a lanceolate shape measuring 0.9 - 1.7 mm long and 0.2 - 0.3 mm broad. The leaf margin is recurved and usually has a slightly toothed tip. The plant's stem is brownish-red to black, and the plant has a glossy appearance.
Uses
Leskeella tectorum (Funck ex Brid.) Hag. ssp. cyrtophylla (Kindb. in Mac. & Kindb.) Wijk & Marg. is commonly used as an indicator species for air quality because it tends to grow in areas with a low level of air pollutants. It is commonly found on walls, rocks, and bark, and is common in urban areas where it is known to tolerate the pollution of the city. It is also used to test the effects of acid rain.
This plant is not known to have any medicinal properties, but it plays a vital role in the ecology of the areas where it grows. It provides a home for many small invertebrates, and it also helps to stabilize the soil, preventing soil erosion. Common Wall Screw-moss is often used as an ornamental plant in green roofs and vertical garden walls, thanks to its ability to grow in small, compact spaces. It also provides a natural way to beautify urban areas and improve their visual appeal.
Light Requirements
Leskeella tectorum ssp. cyrtophylla generally thrives in shaded to partially shaded conditions, such as under the canopies of trees or near buildings that provide cover. It can also tolerate some exposure to direct sunlight, but too much can cause the moss to dry out and become dormant.
Temperature Requirements
This species is considered a cold-adapted moss and grows well in cool and moist environments. It can tolerate extreme temperatures ranging from -40°C to +40°C, but its optimal growth temperature lies between 10°C and 20°C.
Soil Requirements
Leskeella tectorum ssp. cyrtophylla prefers well-drained soil that is rich in organic matter. It can grow on various types of soil, ranging from acidic to slightly alkaline, but it thrives in soil with a pH of 5.0 to 7.5. It is also able to grow on nutrient-poor substrates, such as rock surfaces and soil with low nitrogen and phosphorus content.
Cultivation methods of Leskeella tectorum (Funck ex Brid.) Hag. ssp. cyrtophylla (Kindb. in Mac. & Kindb.) Wijk & Marg.
Leskeella tectorum (Funck ex Brid.) Hag. ssp. cyrtophylla (Kindb. in Mac. & Kindb.) Wijk & Marg. is a drought-tolerant plant, and it's easy to grow. To cultivate this plant, you should prepare a well-draining soil mix with a neutral pH level. You can also mix some peat moss and perlite into the soil to improve its drainage.
You can transplant the plant in the early spring or right after the summer months. It would be best to choose a spot that receives partial shade or full shade, as the plant cannot tolerate direct sunlight. You can also grow it in a container or terrarium as long as you provide adequate ventilation.
Watering needs of Leskeella tectorum (Funck ex Brid.) Hag. ssp. cyrtophylla (Kindb. in Mac. & Kindb.) Wijk & Marg.
Leskeella tectorum (Funck ex Brid.) Hag. ssp. cyrtophylla (Kindb. in Mac. & Kindb.) Wijk & Marg. prefers moist soil, but it doesn't require frequent watering. You can water it once per week during the summer and once every two weeks during the winter months.
The plant can withstand short periods of drought, but if you notice the leaves turning brown or crispy, you should increase the frequency of watering. However, make sure not to overwater the plant, as this can lead to root rot.
Fertilization of Leskeella tectorum (Funck ex Brid.) Hag. ssp. cyrtophylla (Kindb. in Mac. & Kindb.) Wijk & Marg.
Leskeella tectorum (Funck ex Brid.) Hag. ssp. cyrtophylla (Kindb. in Mac. & Kindb.) Wijk & Marg. doesn't require frequent fertilization. You can feed the plant with a balanced fertilizer once every two months during the growing season. Avoid fertilizing during the winter months, as the plant is dormant during this period.
You can also use organic fertilizers like compost tea or fish emulsion. Make sure to dilute the fertilizer according to the instructions on the packaging to prevent fertilizer burn.
Pruning of Leskeella tectorum (Funck ex Brid.) Hag. ssp. cyrtophylla (Kindb. in Mac. & Kindb.) Wijk & Marg.
Leskeella tectorum (Funck ex Brid.) Hag. ssp. cyrtophylla (Kindb. in Mac. & Kindb.) Wijk & Marg. doesn't require pruning as it grows slowly and doesn't produce invasive root systems. However, you can trim back any dead or damaged leaves or branches to maintain the plant's appearance.
It's best to use sterile scissors or pruning shears to prevent the spread of diseases. You can also remove any brown or yellow leaves to allow light to penetrate to the lower parts of the plant.
Propagation of Leskeella tectorum ssp. cyrtophylla
Leskeella tectorum ssp. cyrtophylla can be propagated through a variety of methods including spores and stem cuttings.
Propagation via Spores
Propagation via spores can be a bit more difficult but is the most natural method for reproducing Leskeella tectorum ssp. cyrtophylla. Collecting the spores requires finding mature sporophytes and carefully removing the caps to access the sporangium underneath. Once the sporangium is exposed, the spores can be collected and sown onto a suitable growing medium. Ideally, the medium should be a sterile, well-draining mix with a slightly acidic pH. The spores will require a consistent supply of moisture and high humidity to germinate and grow. It may take several months for the spores to germinate and for the plantlet to establish itself.
Propagation via Stem Cuttings
Propagation via stem cuttings is a quicker and simpler method. Choose a healthy stem with several leaves and take a cutting about 2-3 inches in length. Remove the lower leaves and place the cutting in a container with a well-draining soil mix. Water the cutting and keep it in a semi-shaded location with high humidity. Over the next few weeks, the cutting will establish a root system and begin to produce new growth. Once the plant is well-established, it can be transplanted into its permanent location.
Disease and Pest Management for Leskeella tectorum ssp. cyrtophylla
Leskeella tectorum ssp. cyrtophylla is a hardy plant that is relatively resistant to most diseases and pests. However, like all plants, it is still susceptible to some common issues that can affect its growth and health.
Common Diseases
One of the most common diseases that can affect Leskeella tectorum ssp. cyrtophylla is leaf spot. This is a fungal disease that appears as small black or brown spots on the leaves of the plant. To manage this disease, it is important to remove any infected leaves and dispose of them properly. Using a fungicide can also be effective in controlling leaf spot.
Another common disease that can affect Leskeella tectorum ssp. cyrtophylla is powdery mildew. This is a fungal disease that appears as a white powdery substance on the leaves of the plant. To manage powdery mildew, it is important to remove any infected leaves and improve air circulation around the plant. Using a fungicide can also be effective in controlling powdery mildew.
Common Pests
Leskeella tectorum ssp. cyrtophylla is relatively resistant to pests, but there are a few that can still be a problem. One of the most common pests is the spider mite. These tiny pests can suck the sap from the leaves of the plant, causing them to yellow and eventually die. To manage spider mites, it is important to regularly inspect the plant for signs of infestation and use a miticide to control them.
Another pest that can be a problem for Leskeella tectorum ssp. cyrtophylla is the slugs and snails. These pests can chew on the leaves and stem of the plant, causing damage and eventually killing it. To manage slugs and snails, it is important to remove any debris or hiding places around the plant where they may be living. Using a slug bait can also be effective in controlling these pests.
Overall, by taking a proactive approach to disease and pest management, it is possible to keep Leskeella tectorum ssp. cyrtophylla healthy and thriving. Regularly inspecting the plant, removing any infected or infested material, and using chemical control when necessary can all help to keep this beautiful plant looking its best.
