Echinopsis Oxygona Cactus House Plant in 8.5cm Pot

Echinopsis oxygona, commonly referred to as the "Easter Lily Cactus," is a beautiful and hardy cactus species native to South America, particularly in regions of Argentina, Brazil, and Uruguay. It is prized for its large, fragrant flowers and easy-to-grow nature, making it a favourite among gardeners and cactus enthusiasts.

• Growth Habit: This cactus has a globular to slightly columnar shape and can grow up to 30 cm (12 inches) in height and 10–15 cm (4–6 inches) in diameter. It forms clumps by producing offsets over time.
• Ribs: The plant features distinct ribs, typically 8–14, with small woolly areoles.
• Spines: It has short, radial spines that range from white to brownish, making it less intimidating than some spiny cacti.
• Flowers: Its large, trumpet-shaped flowers are the main attraction. Blooms are pale pink, white, or lavender, reaching up to 20 cm (8 inches) in length. They are fragrant and open in the evening, lasting 1–2 days.
• Adaptability: Well-suited to both indoor and outdoor cultivation, it can adapt to a wide range of growing conditions.

Care Guide

Light Requirements

• Optimal Light: Provide bright, indirect sunlight or partial shade. Outdoors, it thrives in a location with morning sun and some afternoon shade.
• Indoors: Place near a south- or east-facing window. Too much direct sunlight may cause scorching, while too little light can slow growth.

Temperature and Humidity

• Temperature: Prefers warm temperatures between 20–30°C (68–86°F) during the growing season. It is cold-tolerant to around -7°C (20°F) for short periods if kept dry.
• Humidity: Echinopsis oxygona thrives in low to moderate humidity. Avoid placing it in overly humid areas to prevent fungal infections.

Watering

• Frequency: Water sparingly, allowing the soil to dry completely between waterings. During the active growing season (spring and summer), water every 1–2 weeks.
• Dormant Period: Reduce watering significantly in autumn and winter, watering once a month or not at all if kept in a cool environment.
• Method: Use the "soak and dry" method, ensuring excess water drains completely.

Soil and Potting

• Soil: Use a well-draining cactus or succulent mix. You can enhance drainage by adding sand, pumice, or perlite to the mix.
• Pot: Choose a pot with drainage holes to prevent water retention. Terracotta pots are ideal for their breathability.

Fertilisation

• Type: Use a balanced, low-nitrogen cactus fertiliser (e.g., 5-10-10) diluted to half strength.
• Frequency: Feed once a month during the growing season (spring and summer). Avoid fertilising in autumn and winter.

Propagation

• Offsets: Propagation is easiest through offsets, which the plant produces abundantly.
  • Remove offsets carefully and let them callous over for 2–3 days before planting in well-draining soil.
  • Water sparingly until roots establish.
• Seeds: Propagation by seeds is possible but slower. Sow seeds in a well-draining, moist soil mix under bright, indirect light.

Pests and Diseases

• Pests: Common pests include mealybugs, spider mites, and scale insects. Treat infestations with neem oil or insecticidal soap.
• Diseases: Overwatering can cause root rot, the most common issue with this cactus. Always ensure soil is dry before watering.

Repotting

• Frequency: Repot every 2–3 years, or when the plant outgrows its pot or offsets become overcrowded.
• Timing: Best repotted in spring before the active growing season.

Common Issues

1. Sunburn: Sudden exposure to direct, intense sunlight may cause scarring or discolouration. Gradually acclimate the plant to brighter conditions if moving outdoors.
2. Overwatering: Excessive watering can lead to root rot. Stick to a strict watering schedule.
3. Delayed Blooming: Insufficient light or improper watering can delay flowering. Ensure proper light exposure and avoid over-fertilising.

Summary

Echinopsis oxygona is a rewarding and easy-to-care-for cactus that provides stunning, fragrant blooms with minimal effort. Its adaptability, clumping habit, and tolerance to various conditions make it a must-have for both beginners and experienced gardeners.
