Parodia haselbergii

🌵 Care Guide

Parodia haselbergii (formerly Notocactus haselbergii) is a beautiful compact, globular cactus admired for its dense covering of soft white spines and vivid orange-red flowers. Native to southern Brazil, this slow-growing species remains relatively small and is a great choice for cactus collectors.

☀️ Light

• Prefers bright indirect light to partial sun.
• Indoors, place it near a bright east or south-facing window.
• Outdoors, morning sunlight is beneficial, while intense afternoon sun should be avoided to protect its delicate spines.

💧 Watering

• Spring to Early Fall: Water thoroughly only when the soil is completely dry.
• Depending on temperature and humidity, watering may be required approximately every 5–7 days during active growth.
• Winter: Reduce watering significantly or keep the plant dry, especially when kept cool.
• ⚠️ Avoid overwatering, as poor drainage and constantly wet soil can cause root rot.

🌡️ Temperature

• Prefers temperatures between 18–27°C.
• Can tolerate temperatures around 4°C for short periods if kept completely dry.
• Protect from frost and prolonged cold conditions.

🌱 Soil

• Requires a very well-draining, porous cactus soil mix.
• For growing in North India, adding around 10% cocopeat can help balance the mix, especially in dry conditions.
• Adding pumice, perlite, or coarse sand further improves drainage.
• ⚠️ Poor drainage and moisture-retentive soil can significantly increase the risk of root rot.

🍽️ Fertilizer

• Feed once a month during spring and summer with a low-nitrogen cactus fertilizer.
• Do not fertilize during the winter dormant period.

🪴 Potting

• Parodia haselbergii is a slow-growing cactus that generally remains small and globular.
• Use a pot with excellent drainage holes.
• Repot approximately every 2–3 years, preferably in early spring.

🌸 Flowering

• Produces beautiful bright reddish-orange flowers, often during summer.
• Good light and a cool, dry winter rest can encourage reliable flowering.
• The vibrant flowers create a striking contrast against the plant’s dense white spines.
