Care
Watering
Water moderately during the growing season (spring-summer), allowing the substrate to dry out between waterings. In autumn and winter, drastically reduce watering as the plant goes dormant. Avoid stagnant water which causes root rot.
Light exposure
Place Venus Navel in full sun or partial shade to obtain beautiful leaf coloration. Insufficient light slows growth and weakens the plant. Protect it from the hot midday sun in very warm climates.
Soil and substrate
Use a special succulent potting mix or a light mixture made up of potting soil, sand and small gravel in equal proportions. Drainage is essential for this plant which is sensitive to moisture. Change the substrate every two to three years.
Fertilizer
Fertilize very lightly in spring with a diluted succulent fertilizer or a weak balanced feed low in nitrogen. One to two applications are enough; excessive feeding promotes soft, non-hardy growth.
Pruning and maintenance
Remove dead or damaged leaves at the base to maintain appearance. After flowering, rosettes can be divided for propagation. No structural pruning needed.
Diseases and pests
The main threat is root or stem rot from chronic dampness. Check for red spider mites and scale insects, especially indoors. Prevention through good aeration and appropriate watering is preferable.
Did you know?
Its common name 'Venus Navel' comes from the characteristic shape of its fleshy leaves arranged in a rosette, with a curious central depression reminiscent of a belly button. This plant was once used in traditional medicine for its healing properties, although its effectiveness has not been scientifically proven.
Where to buy it
Plant in spring, once all risk of frost has gone. Pick a plant with healthy foliage and roots that are not exposed. Best time: from April to June.
