Cereus Blue

Cereus hexagonus

Looking for a plant you don't have to water much? A cactus might be your answer! Most cacti come from dryland areas and are used to being able to survive weeks without rainfall.  Cereus has a grayish-green twisted stalk with thorns along the five ridges. It blooms from spring to summer with large white blossoms that open at night. Flowers are funnel-shaped and can be up to 25 cm long.

Lighting: Provide a bright location with as much direct sun as possible.

Watering: Cereus is a drought-tolerant plant that does not require frequent watering. Water thoroughly when the soil is completely dry. In winter, water less; just keep the soil from drying excessively. Water with rainwater or distilled water rather than tap water.

Tip: The roots of Cereus are very sensitive to oxygen deficiency. If the soil is poorly permeable to air and water, root rot can set in. The soil should be lightweight with fast drainage and include some organic matter with a pH value of 6 to 7. When watering, water should pass through the medium quickly, rather than stop at the soil surface and slowly seep down, this is what is meant by fast draining soil.
