🌿 Botanical Overview
Scientific Name: Notocactus gutierrezii

Synonym: Sometimes listed under Parodia gutierrezii

Family: Cactaceae

Origin: South America (Argentina)

Growth Habit: Small, solitary or slowly clustering cactus

Size:

Height: 5–10 cm (2–4 inches)

Diameter: 6–10 cm (2.5–4 inches)

Body: Deep green, globular with well-defined vertical ribs

Spines: Thin, golden-yellow to white, arranged evenly in radial patterns

Flowers: Large, bright yellow with a shiny appearance; appear at the plant’s crown

Bloom Time: Late spring to summer, depending on growing conditions

USDA Hardiness Zones: 9b–11

☀️ Sunlight and Temperature Needs
Sunlight:

Prefers full sun to partial shade

Needs at least 4–6 hours of direct or filtered sunlight daily

Indoors: Place near a bright south-facing window or under grow lights

Temperature:

Optimal: 18°C to 28°C (65°F to 82°F)

Can tolerate down to –4°C (25°F) if dry and sheltered

Should be brought indoors or protected in areas with frost

🌞 Adequate light enhances both spine development and flower production.

💧 Watering Routine
Growing Season (Spring to Fall):

Water deeply when the top 2–3 inches of soil are dry

Usually every 10–14 days depending on temperature and humidity

Dormant Season (Winter):

Water very sparingly — about once a month or less

Only water if the plant starts to shrivel slightly, and temperatures remain above 10°C (50°F)

💧 Overwatering is the most common issue — always let the soil dry completely between watering.

🌱 Soil Requirements
Type:

Needs gritty, fast-draining cactus or succulent soil

Ideal mix includes:

50% cactus soil

25% coarse sand

25% perlite or pumice

pH: Slightly acidic to neutral (6.0–7.0)

📌 Avoid peat-heavy soils, as they retain too much moisture.

🌾 Fertilizing Schedule
Active Growing Period (Spring to Late Summer):

Feed every 4–6 weeks with a diluted cactus fertilizer (low nitrogen, e.g., 5-10-10)

Dormant Period (Fall–Winter):

Do not fertilize

🧪 Too much fertilizer can cause weak, etiolated (stretched) growth and stress the roots.

✂️ Pruning and Maintenance
Pruning:

Not required unless removing old flower remnants or damaged tissue

General Care:

Keep the body free of dust with a soft brush

Rotate the pot periodically for even light exposure

🧤 Use gloves when handling — while the spines are fine, they can still irritate skin.

🌿 Propagation
By Offsets:

Though typically solitary, mature plants may form small offsets around the base

Separate carefully once large enough, allow to callous for a few days, and plant in dry soil

By Seeds:

Sow seeds in a moist, sterile cactus mix

Keep at 20–25°C (68–77°F) in filtered light

Germination takes 1–3 weeks

🌱 Seed propagation is slow but ideal for genetic diversity and bulk growing.

🐛 Pests and Problems
Common Pests:

Mealybugs (especially around the base)

Spider mites (in dry indoor air)

Root mealybugs (hidden in the soil)

Common Diseases:

Root rot from overwatering or poor drainage

Fungal spots from excessive humidity or overcrowding

🛡️ Prevent issues with:

Good airflow

Proper watering

Regular inspection

Use neem oil, rubbing alcohol, or insecticidal soap to treat pests.

🌸 Flowering and Visual Appeal
Blooms:

Notocactus gutierrezii produces striking, sun-like yellow flowers often larger than the body of the cactus itself

Flowers open in bright daylight and may last several days

Blooms are followed by small, dry seed capsules

Best Displayed In:

Small ceramic or terracotta pots

Rock gardens and succulent bowls

Windowsills and balconies

📸 Its compact shape and golden blooms make it ideal for macro photography and aesthetic plant displays.

✅ Conclusion
Notocactus gutierrezii is a small but spectacular cactus that combines minimal care with eye-catching blooms. Perfect for windowsills, sunny balconies, or cactus gardens, it thrives with just a little attention to sunlight, watering, and drainage.
