We dug deep to see whether these popular claims have any merit.
Question: Does talking or singing to plants help them grow?
Funny as it is, actual studies have been conducted to test this myth. And in some of those studies, the plants spoken and sung to were more successful. But it’s not necessarily because they feel soothed or socialized. It may simply be that we emit carbon dioxide when we breathe – or sing – which could contribute to the photosynthesis process!
Question: Will a mixture of water and dish soap deter aphids?
Answer: Fiction, mostly.
Aphids can really spoil a successful season, and many people try diluting soap in water and spraying it on their plants to keep them away. While this mixture will immediately rid you of your current aphid problem, it won’t last long — aphids will be back in your brussels sprouts in days. Some detergents and soaps can actually harm your plants. So, if you’re not up for some trial and error, look for insecticidal soaps that are designed for use on flora.
Question: Do banana peels promote plant health and growth?
It’s true. Nutrients from banana peels can be beneficial to certain plants – especially tomatoes and roses. But many expert gardeners suggest composting the peels before you use them in your garden or landscape. Otherwise, they won’t break down very quickly and their nutrient value won’t be as great.
Hack: If you’d rather add the peels directly, cut them into smaller pieces to help them compost faster.
Question: Will coffee grounds increase soil acidicity?
Some plants are better cultivated in acidic soils, and many people believe that coffee grounds can help raise the acidity levels in their gardens. The truth is, most of the acid in the grounds is expelled when you brew your coffee, and the leftover grounds are close to neutral. Regardless, they’re still great as a fertilizer and compost material when they’re applied correctly!
