Care
Watering
Highly drought-resistant plant. Water moderately during the growing season (spring-summer), then gradually reduce watering in autumn and winter. In pots, allow the soil to dry out completely between waterings. Avoid standing water which promotes root rot.
Exposure and light
Requires full sun for at least 6 hours daily for optimal development. Tolerates hot and windy exposures. Indoors, place near a very bright window, preferably south or west-facing.
Soil and potting
Requires very well-draining, poor to moderately fertile soil. Use succulent or cactus compost, enriched with sand or pumice. In the ground, improve drainage with gravel if the soil is clayey.
Fertilizer
Low-maintenance plant. Light feeding in spring is sufficient (diluted succulent-specific fertilizer). Avoid excess nitrogen which promotes soft growth. Lack of feeding does not affect its survival.
Pruning and cutting
Minimal pruning required. Remove dead or damaged leaves at the base. After flowering, you can leave the dry flower stalks or remove them for aesthetics. Regular cleaning prevents pests.
Pests and diseases
Very resistant. Main problems are root rot from overwatering and mealybugs indoors. Check your watering habits and ensure good air circulation at the base. In case of infestation, treat quickly with gentle methods.
Did you know?
Hesperoyucca whipplei is monocarpic: it flowers only once in its life (after 10 to 20 years), then dies after producing seeds. This spectacular flowering, with a panicle of cream-white flowers reaching up to 3 metres tall, is a remarkable event eagerly anticipated by collectors. The Mojave Native Americans used its leaves to make baskets and clothing, and its seeds as food.
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.
