That sounds like one of those viral “too good to be true” plant hacks—and unfortunately, it is.
A dried-out orchid (especially something like a Phalaenopsis orchid) can sometimes be revived, but it won’t suddenly grow “new, green roots” just from adding a spoonful of anything. Orchids don’t work that way biologically.
Here’s what actually matters for root recovery:
- Living tissue check: If the crown (center) or some roots are still firm and green/silver, the plant has a chance. If everything is brown, hollow, or mushy, it’s dead.
- Proper rehydration: Soaking healthy roots briefly in water can help, but it won’t revive dead ones.
- Humidity & airflow: Orchids regrow roots slowly in a humid, well-ventilated environment—not instantly from a “remedy.”
- Clean medium: Fresh bark or moss helps prevent rot while new roots form.
Those “spoon tricks” you see online (sugar water, rice water, random fertilizers) can actually cause rot or mold rather than help.
Realistic expectation: if the orchid is salvageable, root regrowth takes weeks to months, not overnight.
If you want, describe what your orchid looks like (roots, leaves, crown), and I can tell you whether it’s worth saving and exactly how to do it.
