Temperature Requirements
The ideal temperature range for the growth of Lycopodium clavatum L. var. tristachyum Hook. is between 15 and 24 degrees Celsius. It can tolerate temperature fluctuations of up to five degrees Celsius.
Soil Requirements
Lycopodium clavatum L. var. tristachyum Hook. prefers a well-draining, sandy loam soil. It can grow in acidic and alkaline soils, but it needs to be rich in organic matter. The roots of the plant are shallow, so it must be watered regularly to prevent drying out.
Cultivation Methods
Lycopodium clavatum L. var. tristachyum Hook. is a low-maintenance plant that is relatively easy to cultivate. It grows best in sandy, well-drained soil with a slightly acidic pH between 5.0 and 7.0. It can be propagated by spores or by splitting the underground rhizomes.
This plant prefers partial shade to full shade, and it should be protected from intense sunlight as it can damage the leaves. It also prefers a cool, humid environment, so you may need to mist it regularly if you live in a dry climate.
Watering Needs
While the soil should be kept moist, it is important not to overwater Lycopodium clavatum L. var. tristachyum Hook. as it can cause root rot. Aim to keep the soil evenly moist by watering it deeply once or twice a week, depending on the climate and soil type.
It is best to water the plant early in the morning or in the evening, avoiding the hot midday sun. Regular watering is particularly important during the plant's active growing season, which is typically from late spring to early autumn.
Fertilization
Lycopodium clavatum L. var. tristachyum Hook. does not require much fertilization. You can apply a light, all-purpose fertilizer once a month during the growing season, starting in late spring and ending in early autumn.

Pruning
Pruning is not necessary for Lycopodium clavatum L. var. tristachyum Hook. However, if the plant becomes too large or becomes unruly, you can trim it back in late winter or early spring before new growth appears.
To prune, use a pair of sharp scissors or pruning shears to trim back individual stems or fronds. Aim to remove no more than 1/3 of the plant's overall size to prevent shock and stress.
Propagation of Lycopodium clavatum L. var. tristachyum Hook.
Lycopodium clavatum L. var. tristachyum Hook., commonly known as stag's horn clubmoss, can be propagated through spores and vegetative propagation.
Propagation through spores:
To propagate Lycopodium clavatum L. var. tristachyum Hook. using spores, the following steps can be followed:
- Collect mature cones from the parent plant.
- Place the cones in a paper bag and allow them to dry until they split open, releasing the spores.
- Carefully spread the spores on the surface of a moist, soilless medium in a seed tray or pot.
- Cover the tray or pot with plastic wrap to retain moisture and place it in a bright, but not direct, light.
- Keep the soil moist and wait for several weeks for the spores to germinate and grow.
- Once the tiny plants have grown large enough, they can be transplanted into individual containers or directly into the ground.
Vegetative propagation:
Lycopodium clavatum L. var. tristachyum Hook. can be propagated vegetatively using rhizome division or stem cuttings.
Rhizome division:
Rhizome division can be done in the spring or fall and involves the following steps:
- Dig up the parent plant and gently separate the rhizomes into sections.
- Plant each section in a pot or directly in the ground.
- Keep the soil moist and wait for the plants to establish and grow.
Stem cuttings:
Stem cuttings can be taken in the spring or summer and involves the following steps:
- Take a stem cutting from the parent plant, ensuring that it has several leaves.
- Dip the cut end in rooting hormone and plant it in a well-draining soilless mix.
- Keep the soil moist and provide bright, but not direct, light.
- Wait for the cutting to form roots and begin to grow.
- Once the plant has grown large enough, it can be transplanted into a larger container or directly into the ground.
Disease and Pest Management for Lycopodium clavatum L. var. tristachyum Hook.
Lycopodium clavatum L. var. tristachyum Hook., commonly known as Running Pine Clubmoss, is a small evergreen fern that grows in moist, shady areas. While it is relatively disease resistant, it is still susceptible to certain pests and diseases. Here are some common diseases and pests that might affect Running Pine Clubmoss and ways to manage them:
Diseases
1. Root Rot: This disease is caused by various soil-borne fungi that infect the roots of the plant, leading to a decline in its health. The plant may wilt, become stunted, and lose its foliage. To manage root rot, it is essential to avoid overwatering and ensure proper drainage. Additionally, removing and destroying infected plant material can help prevent the spread of the disease.
2. Leaf Spots: Leaf spots are caused by a fungal infection and are characterized by circular or irregularly shaped spots on the plant's leaves. Infected leaves may turn yellow or brown and fall off prematurely. To manage leaf spots, avoid overhead watering and ensure proper ventilation around the plant. Pruning and destroying infected leaves can also help to control the spread of the disease.
Pests
1. Spider Mites: These tiny pests can be challenging to see but can cause significant damage to Running Pine Clubmoss by sucking out its juices, leading to yellowing and wilting of the foliage. To manage spider mites, regular inspection of the plant and the use of insecticidal soap or neem oil can help control their population.
2. Scale Insects: These pests appear as small bumps on the plant's stems and leaves and suck out the plant's sap, leading to poor growth and yellowing of foliage. To manage scale insects, physically removing them using a soft cloth or cotton swab dipped in alcohol or insecticidal soap can help to control their population.
By following these disease and pest management techniques, you can help keep Running Pine Clubmoss healthy and thriving in your garden.
