General appearance
Echinocereus enneacanthus Engelm. var. dubius is a small, slow-growing cactus that typically reaches heights of 5-10 inches. The plant has a ribbed stem covered in sharp, needle-like spines. The stem is usually dark green and cylindrical, sometimes branching at the base. The cactus produces vibrant red flowers, usually about 2 inches in diameter, in late spring to early summer. The flowers have long, narrow petals and a striking yellow center. The plant is drought-tolerant and prefers well-draining soil in bright, sunny locations.
Light Requirements
Echinocereus enneacanthus Engelm. var. dubius (Engelm.) L. Benson requires full sun to partial shade for optimal growth. The plant will flower more profusely if it receives plenty of direct sunlight.
Temperature Requirements
These plants prefer warm temperatures and are not cold-hardy. They grow well in USDA hardiness zones 8 to 11. The optimal temperature for growth is between 70°F to 85°F (21°C to 29°C).
Soil Requirements
Echinocereus enneacanthus Engelm. var. dubius (Engelm.) L. Benson prefers well-draining soil that is nutrient-rich. The pH level of the soil should be slightly acidic to neutral, with a pH range between 6.0 to 7.5. These plants can tolerate some drought, so the soil should be allowed to dry out slightly between waterings.
Cultivation Methods
Echinocereus enneacanthus Engelm. var. dubius (Engelm.) L. Benson is a desert plant, so it needs a warm and dry environment to thrive. It grows best in well-draining soil that provides adequate aeration and drainage. The soil pH should be between 6.0 and 7.5. It is advisable to use a sandy cactus potting mix that contains perlite, sand, and peat moss for cultivation.
This plant requires a lot of sunlight, so it is best to keep it in direct sunlight for at least six hours every day, preferably in the morning. It can also tolerate filtered sunlight, making it an ideal indoor plant if it receives ample light.
Watering Needs
Echinocereus enneacanthus Engelm. var. dubius (Engelm.) L. Benson is drought-tolerant and can survive long periods without water. However, to ensure a healthy plant, it is advisable to water it sparingly, especially during the growing season. During the spring and summer, it requires moderate watering (once every two weeks), while in winter, it requires little to no water.
It would be best to water the plant from the bottom rather than watering it directly from the top. This method allows the plant to absorb water as needed, preventing overwatering, which can lead to rot.
Fertilization
It is not necessary to fertilize Echinocereus enneacanthus Engelm. var. dubius (Engelm.) L. Benson frequently. You can fertilize it during the growing season (spring and summer), using a diluted fertilizer to avoid over-fertilization that can damage the plant.
The recommended fertilizers are cactus or succulent fertilizers, which contain the nutrients your plant needs for proper growth.
Pruning
While pruning is not necessary for this plant, you may need to remove any dead or damaged stems. If you notice any dry or yellow leaves, you can prune them using sterilized pruning shears to prevent the spread of disease.
When pruning, ensure you remove the affected part entirely and disinfect the tool in between cuts. Avoid pruning during the dormancy period or when the plant is weak or stressed; doing so may cause further damage.
Propagation of Echinocereus enneacanthus Engelm. var. dubius (Engelm.) L. Benson
Echinocereus enneacanthus Engelm. var. dubius (Engelm.) L. Benson can be propagated through various methods.
Seeds
The most common method of propagation for Echinocereus enneacanthus Engelm. var. dubius (Engelm.) L. Benson is through seeds. The seeds can be collected from the plant's fruits. Once collected, the seeds should be dried and stored in a cool, dry place until planting.
When planting, it is recommended to sow the seeds in a well-draining soil mixture that has been sterilized. Plant the seeds just below the surface of the soil and keep the soil moist until they germinate. Germination can take anywhere from a few weeks to a few months.
Offsets
Echinocereus enneacanthus Engelm. var. dubius (Engelm.) L. Benson can also be propagated through offsets or pups. Offsets are small plants that grow from the base of the parent plant. Once the offsets are large enough, they can be carefully cut away from the parent plant using a sharp, sterile knife.
Before planting the offsets, allow them to dry for a few days to prevent rotting. Once dried, plant the offsets in a well-draining soil mixture and water sparingly until they establish roots.
