Equisetum hyemale L. var. californicum Milde is also grown as an ornamental plant for its unique appearance. The plant can be grown in containers or in boggy soil, making it ideal for water gardens.
Common names:
Equisetum hyemale L. var. californicum Milde is commonly known as western scouringrush horsetail or California scouring rush.
Light Requirements
Equisetum hyemale L. var. californicum Milde can tolerate both full sun and partial shade but it prefers to grow in partial shade. Direct sunlight can cause the plant to wilt whereas insufficient light may cause slower growth. Therefore, it is best to provide the plant with bright indirect light or partial shade.
Temperature Requirements
The plant grows actively during spring and early summer when the temperature is mild, around 59-77°F (15-25°C). Cooler temperatures can slow down plant growth, whereas temperatures above 86°F (30°C) can cause wilting. During the winter, the plant goes dormant and can tolerate temperature as low as 23°F (-5°C) but not lower.
Soil Requirements
The plant prefers moist, well-drained soil that is slightly acidic in the pH range of 5-6.5. It can tolerate damp soil, but not standing water which can cause root rot. The soil should be rich in organic matter and nutrients. A recommended soil mix for this plant is a combination of peat moss, perlite, and sand.
Cultivation methods
Equisetum hyemale L. var. californicum Milde, commonly known as California scouring rush, is a plant that thrives in wet environments such as marshes, bogs, and riverbanks. If you are planning to grow it, consider planting in a container or in a bog garden with a water depth of 2-6 inches. The plant prefers partial shade but can also do well in full sun in areas with adequate moisture.
Watering needs
Watering is essential for the growth and health of Equisetum hyemale L. var. californicum Milde. It requires consistent moisture during the growing season to thrive, and the soil should be kept wet at all times. If planting in a container, it is important to make sure that the pot has good drainage to prevent waterlogging, which can lead to rotting of roots.
Fertilization
Equisetum hyemale L. var. californicum Milde does not require regular fertilization. If planting in a container, use a slow-release organic fertilizer when planting, but avoid over-fertilization, as this can lead to excessive growth. The plant also benefits from regular application of compost or organic matter around its base to improve soil quality.
Pruning
Equisetum hyemale L. var. californicum Milde requires little to no pruning. It is a slow-growing plant that maintains its shape naturally. If necessary, remove any old or diseased stems from the base of the plant to promote new growth. Be careful when handling the plant, as its stems are rough and can irritate the skin.
Propagation Methods of Equisetum Hyemale L. var. Californicum Milde
Equisetum hyemale L. var. californicum Milde, commonly known as California scouringrush or giant horsetail, is a fast-growing, perennial plant that reproduces through spores and vegetative propagules. The plant is native to North America and prefers growing in moist soils near wetlands and streams. Propagation of Equisetum hyemale L. var. californicum Milde can be done through one of the following methods:
Spore Propagation
Spore propagation is the most natural method of propagating Equisetum hyemale L. var. californicum Milde. In spore propagation, mature spikes (strobili) are harvested in late spring before they release spores and carefully placed in a plastic bag. The bag is then shaken gently to release the spores, which are sieved to remove impurities. The spores are then sown on a sterile, moist soil surface and covered with clear plastic to maintain high humidity in the environment. The tray containing the spores is placed in a shaded location at a temperature of 65-70°F. Germination occurs between 14-30 days, and once the plants are established, they are transplanted to their permanent location.
Vegitative Propagation
Vegetative propagation is another method of propagating Equisetum hyemale L. var. californicum Milde. In this method, sectioned rhizomes or shoots bearing roots are used. The rhizomes can be collected in early spring or late fall before transplanting. The rhizomes are cut into sections, each containing at least one bud, and planted in a well-draining, moist soil with a pH range of 6.0-7.0. The buds should be placed just below the soil surface and lightly pressed in to ensure good soil contact. After planting, the surface of the soil should be mulched to maintain moisture levels in the soil. The rhizomes should be watered regularly and kept out of direct sunlight. New plants will emerge from the buds, and once they reach a height of 6-8 inches, they can be transplanted to their permanent location.
Propagation of Equisetum hyemale L. var. californicum Milde through spore and vegetative propagation is relatively easy. The new plants produced by these methods are clones of the parent plant and have the same characteristics, including growth rates and the ability to tolerate different soil types. These propagation methods allow for the mass production of plants for use in landscaping, habitat restoration, and erosion control.
Disease and Pest Management for Equisetum hyemale L. var. californicum Milde
Equisetum hyemale L. var. californicum Milde or commonly known as Scouring rush is a hardy, perennial plant that is generally resistant to most pests and diseases. However, some pests and diseases can still affect this plant. Here are some common pests and diseases that may affect Equisetum hyemale L. var. californicum Milde and ways to manage them:
Diseases
Fungal diseases: Fungal diseases such as gray mold (Botrytis cinerea) and rust (Puccinia equiseti) can affect the stems and leaves of Equisetum hyemale L. var. californicum Milde. To manage these diseases, remove infected plant parts and ensure the plant has adequate ventilation to prevent moisture buildup. Applying a fungicide can also help control the spread of the disease.
Bacterial diseases: Bacterial diseases such as crown rot (Erwinia carotovora) can cause the plant to wilt and die. Once the plant is affected, it is difficult to manage the disease. Therefore, prevention is the best method by ensuring that the plant has well-drained soil and watering only when necessary.
Pests
Snails and slugs: Snails and slugs can feed on the leaves of Equisetum hyemale L. var. californicum Milde, leaving holes and damage. To manage these pests, handpick them off the plant or apply a slug and snail bait around the base of the plant.
Spider mites: Spider mites can cause stunted growth and yellowing of the leaves of Equisetum hyemale L. var. californicum Milde. To manage these pests, spray the plant with a strong jet of water to dislodge them or apply insecticidal soap or neem oil.
Scale insects: Scale insects can cause yellowing and wilting of the plant leaves. To manage these pests, apply an insecticidal soap or neem oil to the plant or remove them manually with a soft brush.
Equisetum hyemale L. var. californicum Milde is generally a low-maintenance plant. Proper cultural practices such as adequate watering, fertilization and pruning can ensure that the plant is healthy and less susceptible to pests and diseases.
