Easter Lily Cactus Variegated

The Easter Lily cactus is a drought-tolerant plant that requires minimal watering but not too much moisture.  Overwatering can cause root rot and other issues. The Echinopsis cactus should be watered sparingly, allowing the soil to dry out completely before watering again. During the growing season, which is typically in the spring and hot summer seasons (the blooming period), it should be watered once every 2–3 weeks.
Because there is much more sun exposure, even on a shaded porch, a potted Easter lily cactus kept outside typically requires more water than the same plant kept indoors.
In the winter months, the cactus plant should be watered even less frequently, about once a month. When watering the Easter Lily plant, it is important to use well-drained soil and a pot with drainage holes. The cactus should be watered until the soil is moist but not soaked. Any excess water should be allowed to drain out of the pot.
Light Requirements
The Easter Lily cactus requires bright full sunlight or partial shade to thrive. Native to warm locations, this cactus is used in bright, sunny conditions. However, prolonged direct sunlight can burn the Echinopsis cactus and cause damage. Therefore, it is best to place it in a location where it can receive bright light for most of the day. If you are growing the easter lily cactus indoors, a south-facing window is a good choice. 
If the Easter Lily cactus is not receiving enough light, it may become leggy and weak. It may also fail to flower. If this occurs, it is important to move the cactus to a brighter location. If the cactus is receiving too much light, the cactus may turn yellow or brown, and it may become dehydrated. In this case, the easter lily plants should be moved to a location with less direct sunlight. 
Optimal Soil & Fertilizer Needs 
The Easter Lily cactus prefers well-draining potting soil that is slightly acidic.
