That headline is another clickbait-style gardening tip that’s often exaggerated.
Let’s clarify what actually happens if you put a tablespoon of baking soda or similar powder on plants 👇
🌿 First: what people usually mean
This kind of advice usually refers to Sodium bicarbonate.
⚠️ What actually happens if you put it on plants
1. 🌱 It can change soil pH
- Baking soda is alkaline
- It can raise soil pH (make soil less acidic)
- Most plants prefer slightly acidic to neutral soil
👉 Too much can stress or weaken plants
2. 🍃 Leaf damage may occur
- Direct contact can cause:
- Dry patches
- Leaf burn
- Stunted growth
3. 🦠 It may reduce some fungi (limited use)
- Mild antifungal properties
- Sometimes used in very diluted sprays for powdery mildew
BUT:
- Only works in specific conditions
- Not a general plant “boost”
4. 🪴 Soil imbalance risk
- Repeated use can:
- Disrupt nutrient absorption
- Affect beneficial microbes
- Harm long-term plant health
🧠 Where the idea comes from
People sometimes recommend baking soda for:
- Fungus control
- Odor reduction in soil
- DIY gardening hacks
But these are very limited and situation-specific, not universal plant care tricks.
🌼 Better ways to help plants
Instead of baking soda:
- Use compost or organic fertilizer
- Ensure proper watering (not overwatering)
- Provide adequate sunlight
- Use proven fungicides if needed
🟡 Bottom line
Putting a tablespoon of baking soda on plants:
- ❌ Not a general growth booster
- ⚠️ Can harm soil balance if misused
- ✔️ Only sometimes useful in diluted antifungal sprays
