We’ve watched over the past couple of decades as the popularity of the ‘internet hack’ grew. Lifehacks, money hacks, cooking hacks – social media is brimming with hacks to make every area of your life a little easier.
The problem is there are probably more bad hacks out there than good ones. As we’ve come to learn, the internet, especially social media, is a pool of misinformation.
Enter gardening.
Gardening has a long history of misinformation. Because the human species has been participating in agriculture for millennia, there is a ton of gardening advice out there. And the vast majority of it is entirely anecdotal. Science has only just begun to sort through all the gardening lore.
At the end of the day, there are still more unknowns in gardening than certainties. And this vast body of gardening advice keeps getting passed from generation to generation – whether it works or not.
Combine social media with gardening, and you’ve got an endless supply of gardening hacks. How can you tell which ones work and which don’t? Sometimes the only way is to give it a try. And sometimes, your favorite gardening website does the work for you.
Here are five gardening hacks that are just plain bad. When these pop up in your TikTok feed, you can keep on scrolling.
1. Grow Seedlings in Eggshells
The idea behind this hack is that you’re repurposing something that would get composted to start your seedling. The eggshell contains nutrients the small plant needs, and the roots will push through it once planted in the ground, where it will break down, nourishing the soil.
It’s a great idea; it just doesn’t work that way.
I may have ascribed to this waste-reducing hack once upon a time. But experience has taught me better. In its most basic concept, yes, you absolutely can start seedlings in eggshells. However, the root system very quickly outgrows the small capacity of the eggshell. This happens long before the roots would be strong enough to break through the eggshell.
Instead, your seedling can’t develop the large root system it needs to grow, so it either dies or stays tiny and shriveled.
Sure, you could start the seeds in an eggshell with the intention of potting up as it grows, but because the eggshell is so small, you will be subjecting the tiny plant to transplant shock before it’s large enough to be able to recover.
There are better ways to utilize eggshells and far superior options for seed-starting containers.
2. Banana Peel Fertilizer
Yeah, this one is so popular I almost feel bad debunking it.
The idea is that you take a whole bunch of banana peels, chop them into small pieces and soak them in a jar filled with water. The resulting brew is supposed to be filled with nutrients that are great for your plants, things like nitrogen, phosphorous and potassium.
The problem with this hack is that those nutrients, although present in banana peels, are so minuscule as to be almost imperceptible.
You aren’t adding anything of consequence to the soil when you dump rotten banana peel water all over your garden.
Add to that the fact that for organic matter to release the nutrients contained within, it needs to break down first, and you begin to see that you’ve got a jar full of brown water for all your troubles.
If you want genuine banana peel fertilizer, toss those peels in the compost bin and be patient.
3. Use Coffee Grounds to Acidify Soil
Coffee drinkers everywhere were finally justified in their daily habit when this popular hack started making the rounds. (And it’s been around for a long time.)
The concept is quite simple. Coffee is acidic. (Just ask my stomach.) There are popular plants that prefer acidic soil.
Lightbulb! Hey, let’s use those coffee grounds to raise the acidity of our soil!
Unfortunately, the minute you brew your coffee, you’re removing the vast majority of acidic compounds from the coffee. You would have to dump a ton of coffee grounds on your soil to raise the acidity to the level preferred by blueberries, azaleas and other acid-loving plants.
Okay, Trace, you smarty-pants, what if I put unbrewed coffee grounds on my soil instead of used coffee grounds?
Touché.
Yes, using unbrewed coffee grounds will certainly be more effective in raising the acidity level of your soil. But your plants won’t thank you for it. While we humans enjoy coffee for its pep, caffeine has an entirely different role in the plant world.
