If you’re referring to a viral gardening claim about putting a tablespoon of a household ingredient on every plant, be cautious. The result depends entirely on what the tablespoon contains—things like baking soda, sugar, salt, vinegar, coffee grounds, or fertilizer can have very different effects.
For example, salt or concentrated vinegar can damage plant roots, while excessive fertilizer can cause fertilizer burn. A plant doesn’t automatically benefit from adding more of something just because it’s “natural.”
If you send me the full headline, the ingredient, or the rest of the article, I can tell you exactly what would happen and whether the trick is safe for your plants.
