Overview
Selaginella bigelovii Underwood, commonly known as Bigelow's spike moss, is a perennial species of plant that belongs to the Selaginellaceae family. It is native to various regions in North America, including Western United States, Western Canada, and Mexico. The plant is well-known for its delicate fronds and is often used as an ornamental plant in shady gardens.Appearance
Selaginella bigelovii grows up to six inches tall and spreads up to twelve inches wide. The plant has an upright habit with stiff, wiry stems. The stems are fitted with small scale-like leaves, which overlap each other in a geometric pattern and range in color from green to reddish-brown. The leaves of Selaginella bigelovii are dimorphic, meaning that there are two types on each plant - microphylls and megaphylls. The microphylls are very small, while the megaphylls are larger, up to 0.2 inches, and have a more prominent vein pattern. The plant also has cone-like structures called strobili that grow from the tips of the branches. These strobili bear sporangia that produce spores, which help the plant reproduce.Common Names
Apart from Bigelow's spike moss, Selaginella bigelovii is also known as Bigelow's Selaginella and Sierra selaginella.Uses
Selaginella bigelovii is a popular ornamental plant and is often used in garden designs that require a low growing, shade-tolerant plant. It is also commonly grown as a houseplant. The plant requires minimal care, making it an ideal choice for beginner gardeners. Additionally, the plant is used in some parts of the world for its medicinal properties. It is believed to have anti-inflammatory and antioxidant properties that can help alleviate various health conditions, such as arthritis and cardiovascular diseases. However, more research needs to be done to determine its effectiveness. In conclusion, Selaginella bigelovii Underwood is a beautiful and versatile plant that is native to North America. Its unique fronds and low maintenance make it a popular choice for gardens and homes alike.Light Requirements
The Selaginella bigelovii Underwood plant requires bright, indirect light for optimum growth. The plant should not be exposed to direct sunlight as it can damage the leaves and inhibit growth. Greenhouses and indoor spaces with bright, filtered light are ideal for this plant.
Temperature Requirements
The Selaginella bigelovii Underwood plant thrives in temperatures between 60-75°F (15-24°C) during the day and 45-55°F (7-13°C) at night. Warm and consistent temperatures are ideal for optimum growth. Extreme temperatures can cause the plant to dry out or become stressed which can affect its overall health.
Soil Requirements
The Selaginella bigelovii Underwood plant prefers well-draining, moist soil with a slightly acidic pH. A mix of peat moss, perlite and sand is ideal for the plant's growth. The soil should be kept relatively moist but not waterlogged. It is important to avoid allowing the soil to dry out completely as this can cause the plant to wither and die.
Cultivation Methods
Selaginella bigelovii Underwood is a hardy plant that can grow either indoors or outdoors. When grown indoors, choose a location that receives moderate indirect sunlight. The plant can also be grown in a terrarium or a closed container that mimics its natural environment. When grown outdoors, choose a location with partial shade and well-draining soil.
Watering Needs
Selaginella bigelovii Underwood requires frequent watering to thrive. Keep the soil moist at all times without overwatering. During the growing season, water the plant at least once a week or more if the soil feels dry. Reduce watering during the cold season.
Fertilization
To promote healthy growth, fertilize Selaginella bigelovii Underwood once every month. Use a balanced liquid fertilizer applied according to package instructions. Avoid over-fertilizing as it can lead to leaf burn and plant stress.
Pruning
Pruning is not necessary for Selaginella bigelovii Underwood. However, removing dead or damaged leaves can prevent pest infestation. Use sharp shears to cut the leaves back to the base of the stem. Avoid cutting more than a third of the plant at once, as this can lead to stress and stunted growth.
Propagation of Selaginella bigelovii Underwood
Selaginella bigelovii Underwood, commonly known as Bigelow's spike-moss, is a small, creeping plant that belongs to the family Selaginellaceae. The plant is native to the southwestern United States and can be propagated through spores, stem cuttings, and division.
Propagation through Spores
The most common method of propagating Selaginella bigelovii is through spores. Spores can be collected from mature plants that have formed cone-like structures on their tips that contain the spores. To collect the spores, place a paper bag over the cone and gently shake it until the spores fall off and onto the paper bag.
Once the spores have been collected, they should be sown onto a moist, sterile growing medium, such as peat moss or sphagnum moss. The growing medium should then be placed in a warm and humid location, with a temperature of around 70°F (21°C) and a high level of moisture, until the spores germinate and develop into young plants.
Propagation through Stem Cuttings
Another method of propagating Selaginella bigelovii is through stem cuttings. The stem of the plant can be cut into several sections, with each section containing at least one node. The cuttings should be placed in a moist growing medium and kept in a warm and humid location until they start to develop roots and shoots.
The cuttings can also be dipped into rooting hormone before being planted to promote root growth. Once the cuttings have developed roots and shoots, they can be transplanted into a larger pot or into the ground.
Propagation through Division
Propagation through division involves separating the mature plant into several smaller plants, each with its own portion of the root and shoot system. To do this, carefully dig up the mature plant and separate the root system into several smaller sections, each with at least one shoot. The divided plants can then be replanted into individual pots or directly into the ground, depending on the desired growing environment.
Overall, Selaginella bigelovii Underwood can be propagated through spores, stem cuttings, and division. Each method has its own advantages and disadvantages, and the choice of which method to use will depend on the grower's preferences and the specific growing conditions. With proper care and attention, Selaginella bigelovii can thrive and become a beautiful addition to any garden or indoor space.
Disease and Pest Management for Selaginella Bigelovii Underwood
Selaginella bigelovii Underwood is a desert plant which is commonly found in rocky areas or sandy locations. In its natural habitat, the plant is relatively free from bugs and diseases. However, when it is grown in a domestic environment, the plant is vulnerable to two main types of bugs, spider mites and mealybugs. Also, over-watering and fungal diseases can affect the plant.
Common Diseases
One of the most common diseases which affect Selaginella bigelovii Underwood is root rot caused by over-watering. To avoid root rot, you should water the plant only when the soil is dry to the touch. Avoid leaving the plant in standing water for prolonged periods. Another severe disease that affects the plant is caused by fungal infections. To prevent fungus from attacking your plant, avoid watering the foliage. Instead, water the plant at the soil level. If you notice signs of fungal infection, such as black spots on the leaves, eliminate the affected leaves and avoid watering the foliage.
Common Pests
Spider mites and mealybugs are the most common pests that attack Selaginella bigelovii Underwood. Spider mites form webbing on the plant, which you can see on the underside of the plant's leaves. Mealybugs, on the other hand, move slowly and can cluster at the base of the plant near the soil. They leave behind a cotton-like wax that is visible on the plant. To eradicate these pests, you can use insecticidal soap, neem oil, or any natural pesticides. Alternatively, you can wipe the plant with a cotton ball that has been dipped in alcohol. Repeat the alcohol wipe when necessary, and monitor the plant for signs of re-infestation.
Overall, Selaginella bigelovii Underwood is an easy plant to grow, but it is susceptible to bugs and diseases commonly found in a domestic environment. To manage these pests and diseases, you should take preventative measures such as monitoring the plant's water requirements and regularly inspecting it for signs of infestation or damage.
