Important notes
large amounts / pregnancy: Safe as a culinary herb. Avoid very large amounts or concentrated rosemary oil in pregnancy.
Licht
Full sun, 14–16 h of light. Low light makes it sparse.
Water geven
Sparingly: water only once the top of the substrate has dried. Waterlogging is the main killer.
Temperatuur
18–28 °C; warmth-loving, mature plants tolerate light frost.
Luchtvochtigheid
40–55 %. Dry, airy spot.
