If you’re referring to the viral “Place a tablespoon on any plant at home” gardening trick, the missing ingredient is crucial. There is no universal tablespoon treatment that is safe or beneficial for every plant.
For example:
Salt: can damage roots and make soil unsuitable for plants.
Vinegar: can burn foliage and roots; it is primarily a weed-control product, not a general plant fertilizer.
Baking soda: excessive amounts can raise soil sodium/pH and harm plants.
Sugar: doesn’t provide plants with the nutrients they need and can encourage unwanted microbial activity.
Coffee grounds: aren’t a universal fertilizer; large amounts can alter soil conditions and may inhibit some plants.
Fertilizer: can help when correctly formulated and diluted, but a tablespoon of concentrated fertilizer can cause fertilizer burn.
So don’t put an unidentified “one tablespoon” ingredient into every plant pot.
If you send me the ingredient named in the article (or a screenshot of it), I can tell you exactly what to expect, whether it works, and whether it’s safe for your plants.
