Lycopodium inundatum L. var. elongatum Chapman requires low to medium-light conditions. It prefers growing in partial shade and will not do well in direct sunlight for long periods.
Temperature Requirements
This plant prefers cool to moderate temperature. The ideal temperature range should be 16-24°C (60-75°F) during the day and between 10-18°C (50-65°F) at night.
Soil Requirements
The plant prefers growing in damp soil, especially along riverbanks or other water bodies. It requires well-draining, loamy soil that is rich in organic matter. The soil pH range should be between 7.0-7.5 for optimal growth.
Watering Requirements
This plant needs to be kept moist but not waterlogged. It is essential to avoid letting the soil dry out completely, as it can harm the plant. During the summer months, it may require watering once or twice a week, depending on the humidity levels.
Fertilizer Requirements
Lycopodium inundatum L. var. elongatum Chapman does not require significant fertilization. However, in late spring, one can apply a slow-release, balanced fertilizer to stimulate growth.
Cultivation methods
Lycopodium inundatum L. var. elongatum Chapman prefers acidic soils and grows best in partially shaded areas. As an aquatic plant, it grows well in marshy regions, shallow pools, and bogs.
Propagation is mainly through spores, which are produced in the cone-like structures at the tips of the plant. It can also be propagated through stems and rhizome cuttings.
Watering needs
Lycopodium inundatum L. var. elongatum Chapman requires constant moisture, and the soil should never be allowed to dry. Ensure the soil remains saturated but not waterlogged.
Treated water or rainwater is best, as it is free from chemicals and salts that could harm the plant. If using tap water, allow it to stand for some time to allow the chlorine to evaporate.
Fertilization
Since Lycopodium inundatum L. var. elongatum Chapman is adapted to low-nutrient environments, it does not require regular fertilization. However, a slow-release, low-nitrogen fertilizer can be applied during the growing season.
Organic matter such as leaf mold or peat moss can also be added when planting to improve soil structure and fertility.
Pruning
Pruning is not required for Lycopodium inundatum L. var. elongatum Chapman, as it has a creeping habit and does not grow tall. However, it may be necessary to remove any dead or damaged fronds to maintain the plant's appearance.
Propagation of Lycopodium inundatum L. var. elongatum Chapman
Lycopodium inundatum L. var. elongatum Chapman, commonly known as bog clubmoss, is a creeping perennial plant that belongs to the Lycopodiaceae family. The plant is commonly found in boggy habitats, along stream banks, and in wet pine savannas. Bog clubmoss is a decorative plant, and its propagation is not a difficult task.
Propagation Methods
Bog clubmoss can be propagated by spores or vegetatively by rhizome division. Let's discuss these methods in detail:
Propagation by Spores
Lycopodium inundatum L. var. elongatum Chapman can be propagated by spores, but it is a time-consuming process. The following steps can be followed to propagate bog clubmoss by spores:
- Collect spores from the matured clubmoss plants. Spores develop in small, yellowish-brown structures called sporangia, located on the underside of the plant's branches.
- Sow the collected spores on a damp, sterile potting mix.
- Keep the soil moist and warm, and avoid direct sunlight.
- The spores will germinate in three to four weeks and grow into small, thread-like structures called prothalli.
- Once the prothalli develop into mature gametophytes, transplant them into individual pots.
- Provide the newly propagated clubmoss with good watering, lighting, and soil conditions.
Vegetative Propagation
Vegetative propagation is the most preferred method for propagating Lycopodium inundatum L. var. elongatum Chapman. It is less time-consuming and produces plants that are identical to the parent plant. The following steps can be followed to propagate bog clubmoss vegetatively:
- Find a healthy bog clubmoss plant that has several rhizomes.
- Carefully remove the plant from the soil and knock off excess soil from the roots of the plant.
- Separate the rhizomes by gently pulling them apart from the parent plant.
- Plant the separated rhizomes into individual pots or directly into the ground, keeping the soil moist.
- Provide the newly propagated clubmoss with good watering, lighting, and soil conditions.
With proper care and maintenance, Lycopodium inundatum L. var. elongatum Chapman propagated by either method can grow into healthy, attractive, and long-lived clubmoss.
Disease Management
Like any other plant, Lycopodium inundatum L. var. elongatum Chapman is affected by diseases that can stunt its growth, reduce its productivity, and even kill it. To prevent and manage plant diseases, integrated pest management techniques are highly recommended. These are inclusive of:
- Prevention: Maintaining good hygiene, observing proper crop rotations, avoiding overwatering, and planting disease-resistant varieties among other techniques.
- Cultural Control: Consists of pruning, hygienic measures, and proper sanitation methods.
- Biological Control: Involves the use of beneficial microorganisms, parasites, and predators to control the spread of plant diseases.
- Chemical Control: Spraying the plant with fungicides and pesticides to control the spread of diseases.
Common Diseases
Lycopodium inundatum L. var. elongatum Chapman is primarily affected by the following fungal diseases:
- Root Rot: This is caused by the fungus known as Phytophthora cinnamomi, which attacks the roots of the plant resulting in brown, black, or waterlogged root systems. To manage root rot, uproot and dispose of dead and diseased plants, avoid overwatering the soil, and apply chemical fungicides.
- Leaf Spot: This disease is caused by various fungi that attack the plant's leaves, causing them to have brown, red, or black spots. To control leaf spot, remove and destroy infected plant parts, apply preventive fungicides and provide proper aeration and hygiene measures.
- Powdery Mildew: This is a fungal infection that attacks plant's foliage, which appears like a powdery white substance on the leaves' surface. To control this disease, provide an adequate supply of water and humidity, use preventive fungicides, and avoid overcrowding of plants.
Pest Management
The most common pests that affect Lycopodium inundatum L. var. elongatum Chapman include:
- Spider Mites: These are sap-sucking pests that live on the underside of the plant's leaves, causing yellowing and dropping of the leaves. To manage spider mites, spray with appropriate insecticides and maintain good hygiene measures.
- Nematodes: These are soil-borne pests that feed on the plant's roots, causing stunted growth, and reducing productivity levels. To control nematodes, apply chemical nematicides, and provide crop rotation measures.
- Scale Insects: These pests attach themselves to the plant's stems and leaves, forming hard, protective shells. To manage scale insects, apply insecticides, and maintain hygienic measures.
