That sounds like one of those DIY plant “hacks” where a single ingredient is supposed to boost growth or health. Let’s break it down carefully, because what you use and how you use it matters a lot.
What Happens When You Place a Tablespoon on a Plant
The exact effect depends on what the tablespoon contains. Here are some common examples:
1. Sugar
- Effect: Can give a temporary boost to microbes in the soil, but too much sugar can feed harmful bacteria or fungi and damage roots.
- Verdict: Not recommended as a regular treatment.
2. Baking Soda
- Effect: Small amounts can help control fungal issues on leaves when dissolved in water, but dumping a tablespoon directly on soil may alter pH and harm roots.
- Verdict: Use cautiously, usually as a diluted spray.
3. Salt
- Effect: Salt is toxic to most plants. Placing even a tablespoon on soil can burn roots and kill the plant.
- Verdict: Never do this.
4. Coffee Grounds
- Effect: Can act as a mild fertilizer, adding nitrogen and improving soil structure.
- Tip: Mix into soil rather than dumping on top to avoid mold or excessive acidity.
5. Fertilizer (Granular)
- Effect: Designed to slowly release nutrients, can promote growth when used in recommended amounts.
- Tip: Read the label carefully; too much can burn plant roots.
Safe Guidelines
- Always dilute concentrated substances before applying to soil.
- Start with small amounts and monitor plant response.
- Avoid anything that alters soil pH drastically unless you know the plant tolerates it.
- Consider liquid fertilizer, compost, or natural amendments as safer alternatives.
💡 Bottom Line:
A random tablespoon on any plant can help, harm, or do nothing, depending on what it is. Safe options include coffee grounds, compost, or diluted fertilizer, while sugar, salt, or undiluted chemicals can damage your plant.
