Soil Requirements
Lycopodium selago L. var. appressum Desv. thrives in well-draining soil that is rich in humus. It prefers a slightly acidic to neutral soil pH range of 5.5-7.5. It also requires moist soil that is kept consistently moist, but not waterlogged. This plant does well in soil that is amended with organic matter, such as compost or aged manure. It can grow in rocky or sandy soil, but it may need additional fertilization and watering in these conditions.
Cultivation of Lycopodium selago L. var. appressum Desv.
Lycopodium selago L. var. appressum Desv. is a plant that possesses a preference for acidic soil, high altitude and humid conditions. This plant requires soil that is well-draining, rich in humus, and moderately acidic. It can be cultivated outside in suitable climates, or in indoor environments that mimic the same conditions.
Watering Needs
The watering schedule for this plant is essential. It requires watering that is consistent, and neither watering it excessively nor allowing it to dry out. The plant should be watered when the soil feels dry to the touch, but don't let the soil dry out completely as it can damage the plant.

Fertilization
Fertilization is critical for the growth and health of Lycopodium selago L. var. appressum Desv. The plant should be fertilized with an acidic fertilizer, such as a fern or orchid fertilizer, every two to three weeks during growing season, to support growth. Make sure to follow the manufacturer's recommended dilution rates, as over-fertilization can damage the plant.
Pruning
Lycopodium selago L. var. appressum Desv. requires minimal pruning, but pruning dead or dying fronds can promote healthy growth. Trimming the long fronds is recommended to keep the plant tidy and maintain the shape, but be careful not to harm the plant's root system. Use clean, sharp pruning shears to reduce the risk of harming the plant. Pruning usually takes place in spring when new growth appears.
Propagation of Lycopodium selago L. var. appressum Desv.
The Lycopodium selago L. var. appressum Desv. is a perennial spore-bearing plant native to Europe, Asia, and North America. It is commonly known as the Alpine Clubmoss because it grows in high altitudes often in mountainous regions.
Propagation methods
There are two main ways of propagating Lycopodium selago L. var. appressum Desv.:
Spore propagation
The Lycopodium selago L. var. appressum Desv. reproduces through spores. Spores are small, dust-like particles produced in the plant’s sporangium located at the end of the leaves’ stems. To propagate Lycopodium selago L. var. appressum Desv. using spores, you need to gather the spores during the plant's fertile period, which is in the summer. You can then scatter the spores on moist soil or a potting mixture of peat moss and perlite. Cover the soil lightly with plastic wrap to keep the environment moist and preferably place it near a north-facing window for indirect sunlight.
Vegetative propagation
The Lycopodium selago L. var. appressum Desv. can also be propagated vegetatively. Vegetative propagation involves removing a section of a plant and rooting it to form a new individual. It is the best method for propagating Lycopodium selago L. var. appressum Desv. if you want to produce a clone of the parent plant. To propagate Lycopodium selago L. var. appressum Desv. vegetatively, you need to wait for the plant to produce stolons or runners. These are horizontal stems that grow on the surface of the soil. Cut a section of the stolon, around 5-10 cm long and plant the cutting into a potting mixture of peat moss and perlite. Water the cutting sparingly to avoid waterlogging it.
Disease Management
Lycopodium selago L. var. appressum Desv. is susceptible to several diseases, including:
- Fungal leaf spot: This is caused by fungi and is characterized by the formation of small, circular spots on the leaves. To manage this, remove and destroy infected leaves, ensure good air circulation in the plant and apply fungicides.
- Root rot: This is caused by waterlogging and poor drainage, leading to the rotting of the plant roots. To manage this, ensure proper drainage and watering practices.
- Anthracnose: This is caused by fungi and results in the wilting and death of young leaves. To manage this, remove and destroy infected leaves, ensure good air circulation and apply fungicides periodically.
Pest Management
Lycopodium selago L. var. appressum Desv. is also susceptible to various pests, including:
- Spider mites: These are tiny, sap-sucking pests that cause yellowing and curling of leaves. To manage these, apply insecticidal soap or neem oil to the affected plant.
- Scale insects: These are small, immobile pests that attach themselves to the plant and suck sap, causing yellowing and stunted growth. To manage these, prune heavily infested parts of the plant and apply horticultural oils.
- Mealybugs: These are soft-bodied pests that leave a white, cottony residue on the plant and cause yellowing and wilting. To manage these, remove and destroy heavily infested parts of the plant and apply insecticidal soap or neem oil.
Regular monitoring, good cultural practices, and careful selection of pesticides are essential to manage diseases and pests of Lycopodium selago L. var. appressum Desv. effectively.
