It is characterized by its cylindrical stem which has a diameter of 1-4 inches (2.5-10 cm), covered in small, white spines that are 1/4 to 1/2 inches (0.6-1.3 cm) long. The plant also has a deep taproot and the stem is often leaning or prostrate, allowing it to grow in crevices and rocky terrain. The flowers are showy, bright pink, and are up to 2.5 inches (6.4 cm) long and 2 inches (5 cm) wide. They usually bloom in late spring to early summer and are followed by small, edible red fruits that resemble strawberries.
Uses of Echinocereus enneacanthus Engelm.
Echinocereus enneacanthus Engelm. is often grown as an ornamental plant for its beautiful flowers and unique appearance. The plant is easy to grow and care for, making it a great addition to rock gardens and dry landscapes. It is also used in traditional medicine as an analgesic to treat pain and inflammation.

Overall, Echinocereus enneacanthus Engelm. is a stunning cactus that thrives in arid and rocky regions. Its beautiful pink flowers and unique appearance make it a popular choice for ornamental gardening, while its medicinal properties and edible fruits give it additional value.
Light Requirements
Echinocereus enneacanthus Engelm. prefers full sun to partial shade. 6 hours of direct sunlight is ideal for its healthy growth. However, in hotter climates, it may require some shade during the hottest part of the day. Growing the plant indoors requires bright light, preferably near an east or south-facing window.
Temperature Requirements
The ideal temperature range for Echinocereus enneacanthus Engelm. growth is between 60°F-85°F (15°C-29°C). It can withstand temperatures as low as 30°F (-1°C) but requires winter protection in colder climates. To promote blooming, the plant requires a cool and dry winter rest period.
Soil Requirements
The plant grows best in well-drained, sandy, or gravelly soil that is acidic to slightly alkaline (pH 6.0-7.5). A sandy loam mixture of 2 parts sand, 2 parts perlite, and 1 part soil is ideal for container-grown plants. In-ground planting requires the addition of organic material such as compost or peat moss to improve soil texture and fertility. The soil must not retain water, but it must maintain moisture for proper plant development.
Cultivation
Echinocereus enneacanthus Engelm. is best suited for cultivation in a dry, desert-like climate. It thrives in well-draining soil that is slightly acidic and sandy. If planting in regions with high rainfall, ensure that the soil has excellent drainage to prevent waterlogging. Plant the cactus in a full sun position, preferably in a location that receives direct sunlight.
Watering Needs
The Echinocereus enneacanthus Engelm. is drought tolerant and does not require frequent watering. It is best to water the plant thoroughly once every two to three weeks during the active growing season. Avoid over-watering and ensure that the soil is dry before watering again. During the winter dormant period, the plant requires minimal watering.
Fertilization
The Echinocereus enneacanthus Engelm. does not require frequent fertilization, and over-fertilizing can harm the plant. It is best to fertilize the plant once every three to four months during the active growing period, using a balanced fertilizer formulated explicitly for cacti. Apply the fertilizer sparingly to avoid over-fertilizing.
Pruning
Pruning the Echinocereus enneacanthus Engelm. is not necessary, and it is best to avoid pruning unless necessary. If pruning is necessary, use clean, sharp tools to avoid damaging the plant. When pruning, cut close to the main stem or joint to promote proper sealing and prevent rotting.
Propagation of Echinocereus enneacanthus Engelm.
Echinocereus enneacanthus Engelm., commonly known as "Strawberry Hedgehog Cactus," is a slow-growing cactus native to the southwest United States and northern Mexico. This plant can be propagated using several methods.
Seed Propagation
Seeds are an easy and effective way to propagate Strawberry Hedgehog Cactus. Sow the seeds in well-draining soil and keep them moist until they germinate, which can take several weeks. Once the seedlings are big enough, they can be transplanted into their own pots.
Offset Division
Another common method of propagating this cactus is by dividing offsets from the parent plant. Gently remove the offsets from the parent and let them dry out for a few days before planting them in their own pots with well-draining soil. Keep them lightly moist, and within a few weeks, they should start producing roots.
Stem Cuttings
Echinocereus enneacanthus can also be propagated from stem cuttings. Cut a healthy stem from the parent plant using a sharp, sterile knife or scissors. Let the cut end dry out for a few days before planting it in well-draining soil. After a few weeks, the cutting should start producing roots, and the plant will start to grow.
Disease Management
Echinocereus enneacanthus Engelm. is susceptible to various diseases that can significantly affect its growth and health. Some of the common diseases that affect this plant include root rot, wilt disease, and powdery mildew.
Root Rot: Typically caused by fungal pathogens such as Phytophthora and Pythium, root rot is a common disease that affects E. enneacanthus. It causes the plant's roots to rot, leading to wilting and yellowing of the leaves. To manage this disease, remove and discard infected plants, promote adequate drainage, and avoid overwatering.
Wilt Disease: Caused by Fusarium oxysporum f. sp. echinocerei, the wilt disease leads to the wilting of the plant's stem and drooping of the fruits. To manage this disease, isolate infected plants, improve soil drainage, and use certified disease-free plants.
Powdery Mildew: This disease is caused by the fungus Erysiphe cichoracearum and results in a white or gray powdery coating on the plant's leaves. To manage this disease, consider dusting the plant with a sulfur or copper-based fungicide and improve air circulation around the plant.
Pest Management
E. enneacanthus is susceptible to various pests, including spider mites, mealybugs, and scale insects. These pests can quickly infest the plant and cause significant damage.
Spider Mites: These pests cause visible yellowing of the leaves, and in severe cases, they may result in defoliation. To manage spider mites, create a moist environment around the plant by misting and keeping the area surrounding the plant clean.
Mealybugs: These pests hide in cracks and crevices, and their presence is indicated by a sticky substance on the plant's surface. To manage mealybugs, introduce natural predators such as ladybugs and lacewings and apply a solution of dish soap and water to the plant's affected areas.
Scale Insects: They appear as small brown bumps on the plant's surface. These pests suck the sap from the plant and cause it to wilt and die. To manage scale insects, use a cotton swab or a soft brush to remove them from the plant's surface, or use horticultural oil to suffocate them.
