Care

Light

Place your Datura in the sunniest spot possible, in direct sunlight. This plant needs heat and light to flower well. Avoid overly shaded areas where its growth would be slowed and flowering compromised.

Watering

Water regularly during the growing and flowering period, keeping the soil moist but well-drained. Reduce watering in winter or at the end of the season. Caution: this plant cannot tolerate standing water, which promotes root rot.

Soil

Rich, well-drained and slightly fertile soil is ideal. Datura adapts to different soil types but prefers loose substrate. You can add well-decomposed compost at planting time to improve soil structure.

Fertilizing

Apply balanced fertilizer or one slightly rich in potassium every 15 to 20 days during flowering. Moderate feeding is sufficient; excess nitrogen would encourage foliage at the expense of flowers. Gradually reduce fertilizing at the end of the season.

Pruning and maintenance

Pinch young plants to encourage better branching and compact form. Regularly remove faded flowers to extend blooming. At the end of the season, cut the plant back to ground level or remove it depending on your region's climate.

Pests and diseases

Datura is generally hardy but can be affected by spider mites in dry, hot conditions. Watch for stem rot if humidity is excessive. Good air circulation prevents most fungal problems.

Did you know?

Datura wrightii is a plant with psychoactive properties historically used by certain Native American cultures in shamanic rituals. However, its alkaloids are extremely toxic and unpredictable in dosage, causing numerous accidental poisonings. Its nickname "Devil's Trumpet" reflects this dangerous reputation, though its botanical beauty has always fascinated exotic plant collectors.

Where to buy it

Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
