WaterAdam's Needle requires minimal watering as it is a drought-tolerant plant. Water deeply but infrequently, waiting until the top few inches of soil are completely dry before watering again. As a general rule, watering every 7 to 10 days during the growing season is sufficient, reducing to once a month or not at all during the dormant winter period. When you do water, provide about 1 gallon to ensure it reaches the deep roots, avoiding shallow sprinklings that don't benefit the plant. Overwatering can lead to root rot, so err on the side of under-watering with this hardy species.
LightAdam's Needle thrives best in full sunlight conditions, an ideal spot would be a south-facing location where it can receive at least 6 to 8 hours of direct sunlight daily. Though it can tolerate partial shade, too much shade can reduce the plant's vigor and blooming potential. Avoid deep shaded areas which will not promote healthy growth for this sun-loving plant.
TemperatureAdam's Needle is cold hardy and can tolerate temperatures as low as 0°F, making it suitable for growing in a wide range of climates. It prefers a temperature range between 60°F and 90°F for optimal growth. Ensure proper drainage and avoid excessive moisture in soil during cold weather to prevent root damage.
PruningPruning Adam's Needle is primarily for aesthetic purposes and to remove dead or damaged leaves. Cut back the spent flower stalks to the base after blooming to encourage new growth. Pruning is best done in the spring; however, minimal pruning is needed since the plant's natural shape is generally desirable.
CleaningAs needed
SoilWeak-leaf yucca thrives best in a well-draining soil mix consisting of 50% potting soil and 50% sand or gravel to ensure proper drainage. The ideal soil pH for this plant is between 5.5 and 7.5.
RepottingWeak-leaf yucca should be repotted every two to three years or when it has outgrown its current pot, which is typically evident by roots emerging through the drainage holes.
Humidity & MistingWeak-leaf yucca prefers low to moderate humidity levels, being quite tolerant of dry air, so there's no need to artificially increase humidity for this plant.
Suitable locationsIndoor
Place weak-leaf yucca in bright, indirect light indoors.

Life cycleYucca flaccida 'Ivory', commonly known as Ivory Yucca, begins its life as a seed that germinates in well-drained soil under full sun conditions. Upon germination, it develops a rosette of sword-shaped leaves and starts to establish a robust root system. As it matures, the plant exhibits vigorous growth, with leaves becoming more numerous and the rosette expanding in girth. In the reproductive stage, typically during the warmer months, it sends up a tall flower stalk bearing clusters of ivory-white, bell-shaped flowers, which attract pollinators and may set seed if successfully fertilized. After flowering, if seeds are produced, they may be dispersed by wind or wildlife, allowing new plants to grow elsewhere. Yucca flaccida 'Ivory' is a perennial plant, capable of living for many years, repeating its growth and reproductive cycles annually.
PropogationPropogation time
Spring to Summer
The most popular method for propagating Yucca flaccida 'Ivory', commonly known as Weak-leaf Yucca, is through division. This process is best carried out in the spring, as it allows the entire growing season for the new plants to establish. To propagate by division, carefully dig up a mature plant, taking care not to damage the root system. Using a sharp, sterilized knife, divide the root ball into sections, ensuring each section has at least one growth point or stem. Replant the divisions at the same depth they were growing before, allowing for ample space between the new plants. Water the divisions well to help establish them, but be careful not to overwater as Yuccas prefer dry, well-drained soil. This method is reliable and produces new plants that are true to the parent's characteristics.
