Houseplant clinic: why is my mistletoe cactus turning brown?

Don’t be overly cautious when watering Rhipsalis – to thrive it needs regular hydration and good drainage

What’s the problem?
My mistletoe cactus (Rhipsalis) thrived for more than five years, but recently started to brown, with strands falling off. I repotted it into a slightly larger pot with no drainage holes and a layer of gravel at the bottom, but it continues to decline despite weekly watering. How can I save my plant?

Diagnosis
Your mistletoe cactus probably isn’t getting sufficient hydration. Cautious watering can lead to soil that is superficially damp but remains dry at a deeper level. This often manifests as browning stems, shrivelling and segments dropping off as the plant becomes stressed due to a lack of moisture at the roots.
