Overview
Echinocereus enneacanthus Engelm. var. stramineus (Engelm.) L. Benson is a cactus species that is native to Southwestern United States and Northern Mexico. It is commonly known by various names such as Straw-colored Hedgehog Cactus, Strawberry Hedgehog, Strawberry Cactus or Pitaya de Oso. This plant belongs to the family Cactaceae, which has over 1500 known species.
Appearance
Echinocereus enneacanthus Engelm. var. stramineus is a low-growing, clumping cactus that forms a rounded cluster up to 40cm wide. It develops from a single stem but later forms offsets that grow into small clumps. The cactus has cylindrical stems that are 3-8cm in diameter and can reach up to 25cm in length. It has 8-12 ribs with visible areoles that carry spines. Each areole has between 6-11 radial spines that are yellow or red and about 4-8mm in length, and one or two central spines that are longer and thicker than the rest at 10-35mm long. The flowers develop from the top of the stem, are funnel-shaped and 4-8cm wide in shades of pink, magenta or red.
Uses
Echinocereus enneacanthus Engelm. var. stramineus is a popular cactus in cultivation. It is commonly grown as an ornamental plant for its beautiful appearance, unique structure, and attractive flowers. The cactus is also a source of food for native peoples in its natural range. Its fruit, Pitaya de Oso, or bear's pitahaya, is edible raw and is often used in jams, jellies, and syrups. Some indigenous tribes also use the plant for medicinal purposes such as treating burns, wounds, and stomach problems.
Cultivation
Echinocereus enneacanthus Engelm. var. stramineus is easy to grow and maintain. It prefers dry, well-drained soil and survives well in full sun but tolerates some shade. It is drought-tolerant and needs watering only occasionally during dry seasons. To propagate, stem cuttings can be planted easily and offsets may also be separated from the mother plant and individually potted. The mature plant can handle frost if kept dry, but for seedlings, it is best to protect them from frost.
Light conditions
Echinocereus enneacanthus var. stramineus requires bright and direct sunlight. It can tolerate partial shade, but the growth rate may slow down, and the plant may not bloom as much. Therefore, it is best to place the plant in a location where it can receive plenty of sunlight for at least six hours per day.
Temperature conditions
This plant species is native to the hot and arid regions of North America, so it prefers warm temperatures. The ideal temperature range is between 70 to 85 degrees Fahrenheit during the day and 50 to 65 degrees Fahrenheit at night. It is crucial to avoid exposing the plant to temperatures below 40 degrees Fahrenheit, as this may cause damage to the plant.
Soil conditions
Echinocereus enneacanthus var. stramineus thrives in well-draining, sandy soil that has excellent air circulation. The soil should be slightly acidic to neutral, with a pH range between 6.0 to 7.5. The addition of perlite or sand to the soil mix can help improve drainage and prevent root rot. It is essential to avoid overwatering the plant, as it can be susceptible to fungal diseases.
Cultivation Methods
Echinocereus enneacanthus Engelm. var. stramineus (Engelm.) L. Benson is a cactus that can grow both indoors and outdoors. For indoor cultivation, it is best to place the plant in a bright room or near a window that receives plenty of sunlight. Outdoors, the plant can be grown in a sunny, well-draining area. The soil should be prepared with coarse sand, perlite, and a small amount of organic matter. The plant should be planted at a depth where the roots are covered, and the stem is above the soil line. It is essential to ensure that the soil is well-draining to prevent root rot.Watering Needs
Echinocereus enneacanthus Engelm. var. stramineus (Engelm.) L. Benson is drought-tolerant and prefers infrequent watering. The plant should be watered deeply and allowed to dry out before watering again. During the winter months, the plant should be watered sparingly as it goes dormant. Overwatering can lead to root rot, which can be fatal.Fertilization
Fertilization should be done in the spring and summer months using a balanced, water-soluble fertilizer. The fertilizer should be diluted to half the recommended strength to avoid burning the roots. It is not necessary to fertilize the plant during the fall and winter months.Pruning
Echinocereus enneacanthus Engelm. var. stramineus (Engelm.) L. Benson requires minimal pruning. Dead or unhealthy branches can be removed using pruning shears. It is essential to sterilize the pruning tools before and after use to prevent the spread of disease. Pruning should be done in the spring or summer months when the plant is actively growing. It is best to avoid pruning during the fall and winter months as the plant goes dormant and is susceptible to damage.Propagation of Echinocereus enneacanthus Engelm. var. stramineus (Engelm.) L. Benson
Echinocereus enneacanthus Engelm. var. stramineus (Engelm.) L. Benson can be propagated using various methods.
Seed Propagation
The most common method of propagation is through seeds. The seeds should be sown in well-drained soil and kept moist until germination. It is essential to provide bright, indirect sunlight and maintain a temperature of 70-80°F for optimal results. The seedlings can be transplanted to individual pots once they are big enough to handle, typically after a few months.
Offset Propagation
Another method of propagation is through offsets. These are small plantlets that emerge from the mother plant's base and can be gently removed. The offsets should be allowed to dry for a few days, after which they can be placed in well-draining soil. Keep the soil moist and in a warm, bright area until new growth appears.
Stem Cutting Propagation
Stem cuttings can also be used to propagate Echinocereus enneacanthus Engelm. var. stramineus (Engelm.) L. Benson. Cut a healthy stem at least 3-4 inches long and let it dry for a few days. Once the cut end has calloused, put it in moist soil and keep it in a shaded area until new growth appears. Provide bright, indirect sunlight once new growth has emerged.
Grafting
Grafting is another propagation method for Echinocereus enneacanthus Engelm. var. stramineus (Engelm.) L. Benson. This method involves attaching a cutting from the plant to a rootstock of a related cactus species, which will serve as the plant's root system. Grafting is a more advanced method and is typically done by experienced gardeners or horticulturists.
Disease and Pest Management for Echinocereus enneacanthus Engelm. var. stramineus (Engelm.) L. Benson
