Mammillaria spinosissima ‘Un Pico’

🌵 Care Guide

Mammillaria spinosissima ‘Un Pico’ is a beautiful special form of Mammillaria spinosissima, admired for its attractive spination, compact growth, and beautiful crown of flowers. It is a relatively easy-to-grow cactus that does well in bright light, porous soil, and careful watering.

☀️ Light

• Prefers bright direct sunlight, ideally around 5–6 hours daily.
• Morning sunlight is especially beneficial for healthy growth and flowering.
• During extremely hot summer weather, provide some afternoon shade to prevent scorching.
• Indoors, place it near a bright south-facing or west-facing window.
• Gradually acclimate the plant to stronger sunlight if it has been grown in lower light.

💧 Watering

• Spring–Fall: Water thoroughly only when the soil is completely dry.
• Allow excess water to drain completely before watering again.
• Winter: Water very sparingly or keep the plant dry when conditions are cool and humid.
• ⚠️ Mammillarias are drought-tolerant but are sensitive to prolonged wet soil.

🌡️ Temperature

• Prefers warm temperatures around 20–30°C during active growth.
• Can tolerate cooler nights down to around 5°C if kept completely dry.
• Protect from frost and prolonged cold, wet conditions.

🌱 Soil

• Requires a porous, well-draining cactus mix.
• Add pumice, coarse sand, or perlite to improve drainage and aeration.
• A gritty mixture helps maintain healthy roots and prevents water retention.
• Avoid heavy soils that remain wet for long periods.

🍽️ Fertilizer

• Feed once a month during spring and summer with a low-nitrogen cactus fertilizer.
• Fertilize only while the plant is actively growing.
• Do not fertilize during autumn and winter.

🪴 Potting

• Always use a pot with excellent drainage holes.
• Repot approximately every 2–3 years or when the plant outgrows its container.
• It generally prefers being slightly snug in its pot rather than being planted in an excessively large container.
• Allow disturbed roots to dry before watering after repotting.

🌸 Flowering

• Produces beautiful pink flowers that can form a crown around the top of the plant.
• Flowering generally occurs during spring or early summer.
• A cool, dry winter rest can help encourage flowering.
• Good sunlight and healthy active growth are important for reliable blooming.

🌵 Growth & Appearance

• ‘Un Pico’ is a distinctive form of Mammillaria spinosissima with attractive dense spination.
• Its compact size makes it well suited to container cultivation and cactus collections.
