There’s nothing quite like picking fresh, homegrown vegetables straight from the vine and bringing them directly to your dining table. Plus, it’s the ultimate way to elevate those crisp, summer salads!
But whether you’re learning how to grow tomatoes from seeds or cultivating tomatoes in pots, you’ll inevitably face one frustrating hurdle — garden pests.
In fact, keeping your plants safe from hungry intruders such as squirrels, birds, or even deer is often the biggest obstacle to achieving that perfect, juicy harvest this season.
And while there are plenty of natural pest repellents or companion plants to help deter pests, there is one unlikely item found in your bathroom that can do just the trick.
So why are gardeners putting a bar of ‘special’ soap by their tomato plants?
Hang a bar of soap near tomato plants
It seems like a simple bar of soap can do so much more than just clean your skin or leave you smelling fresh.
Interestingly, its strong fragrance acts as a powerful deterrent for garden pests. However, it’s not just any standard store-bought brand that will work; you’ll need to use Irish Spring Moisture Blast Deodorant Bar Soap.
According to a research study conducted by the University of Nebraska in 1991, using “bars of fragrant soap will keep deer from crops at critical times.”
This makes it an ideal solution to hang by your tomato crops, acting as a barrier to ensure they’re not devoured or ruined by all types of yard intruders.
Perhaps the only caveat is that once the fragrance starts to wear off, they’ll soon be back. So, it’s best to only use this easy hack alongside other methods to ensure your garden remains a pest-free zone.
How to use soap by tomato plants (and what not to do)
There are a couple of ways you can use soap near your tomato plants. The first is to drill a small hole through the soap, thread some string, and hang it from stakes or a plant trellis. For best results, leave the packaging on before hanging, and experts suggest that a single bar is a sufficient scent barrier for any tomato plants within a 3-foot area.
Another option is to place the bar inside a small, fine-mesh pouch before hanging it near your crops instead. Once the soap fragrance wears off, you can simply replace it with a fresh bar.
Bear in mind that if soap is used incorrectly, it may harm your plants. Since this may contain sodium hydroxide, or contemporary lye, it can scorch foliage and harm plant tissues. So be sure that no soap residue drips onto your tomato plants or soil.
