I've inherited a Christmas Cacti from an elderly friend - how do I clean it?

This plant is incredibly greasy and dusty. I'd like to be as noninvasive to start the care as I have no idea how many years this plant has been in its container. I do know it hasn't flowered for about 7 years, but that could happen because of the climate here. Any help appreciated. Thanks

I own a Christmas cacti too. I run the shower on it to clean it. It might not flower for four reasons. It might need to be re potted with fresh dirt. It might need some fertilizer. It might need a better window in which to get enough sun to encourage flowering. It might not be getting enough water.
Reply:I just keep mine in a garage near the door so it gets semi light and brig it out once in a while and shower it gently with water. Always let it dry out between waterings.
Reply:How to get a Christmas Cactus to Bloom:





These plants are easy to grow but are sometimes difficult to get to bloom. A medium light intensity and a soil high in organic matter are recommended. Do not allow the plant to dry out, water when the soil surface begins to feel dry. The plant may be kept drier in fall. Any fertilizer may be used according to label directions. Cool temperatures or long nights are required to induce blooming. The plants bloom when given night temperatures near 55 degrees and day temperatures below 65 degrees.





Flowering is related to day length and night temperatures. The temperature range for flower bud development is 55 to 60 degrees for a six week period. If temperatures remain in this range they will develop buds regardless of day length. If temperatures get above that range, the plant will need 13 hours of uninterrupted darkness each night. This can be done by placing them in a completely dark room, or covering them for the recommended time, or longer, each night with a dark piece of cloth.





Or just keep the plants in total darkness like a closet till buds develop. For holiday blooms this usually means in late September to mid October.





During flower bud formation, stop fertilizing and only water enough to keep the leaves from becoming shriveled. Once buds do form then you can keep the plant in normal light and temperatures. Keep it evenly moist and fertilize every other week with a mild fertilizer solution.





(Mealybugs: Wash with soapy water or wipe off with alcohol using cotton swab.) As for cleaning the plant, I don't see any harm in soapy water or just plain water. I would contact a florist.
