🌱 Germinate Lophophora and Copiapoa seeds 1. Prepare the substrate

Very mineral : mixture e.g. 70–80% pumice, lava, quartz sand, perlite.
A small portion of fine cactus soil or coconut fiber (max. 20–30%) so that it is not too sterile.
Moisten everything beforehand (slightly damp, not wet!).
👉 Tip: Many growers sterilize substrate briefly in the microwave or oven (to prevent fungus).
2. Vessel
Shallow bowls or small pots, preferably with a transparent lid (mini greenhouse, zip bag or storage box).
Important: Air circulation must be adjustable → ventilate slowly later.
3. Sowing
Simply sprinkle seeds onto the surface (light germinates!).
Do not cover with substrate – at most, dust lightly with fine sand or vermiculite.
Press down gently with a spoon or the bottom of a glass.
4. Conditions for germination
Temperature: 22–28 °C during the day, slightly cooler at night.
Light: bright, but not direct sunlight (fluorescent tube or LED is ideal).
Humidity: Keep the substrate permanently moist (closed cover retains moisture).
👉 Germination usually takes 7–14 days, sometimes 3–4 weeks.
5. Care of the seedlings
Keep closed for 2–4 weeks after germination.
Then slowly get used to fresh air (open the lid a little every day).
Water very carefully (preferably from below), never let the substrate dry out – but also avoid waterlogging!
For the first few months they grow very slowly and remain like small green balls.
6. Hardening
After about 3-4 months they can tolerate more light and drier periods.
Later (6–12 months) they can be treated like adult Lophophora: very mineral substrate, keep dry in winter.
Care of adult plants
Light: full sun promotes compact, healthy growth.
Temperature: warm in summer, cool in winter (5–12 °C), as dry as possible – this simulates rest time.
Water:
Summer: water moderately, always allow to dry out.
Winter: hardly water at all.
Fertilization: during the growing season (spring-summer) once a month with special cactus fertilizer (low nitrogen content).
Repotting: every few years into fresh mineral substrate.
Differences between Lophophora and Copiapoa
Lophophora: spherical, without thorns, very slow growing, extremely sensitive to waterlogging.
Copiapoa: from Chile, usually with thorns, somewhat more robust and better adapted to full sun.
Tips for healthy plants
Always ensure good drainage .
Beware of overwatering – the most common mistake!
In summer, place plants outdoors (in a sunny place, protected from rain).
It is essential to observe the rest period in winter, otherwise the lifespan will suffer.
