Want Juicier, Sweeter Tomatoes? Try This Surprising Trick

There's nothing quite like a sun-warmed tomato, plucked fresh from the garden and still carrying the scent of summer. Whether you're layering thick slices into a juicy Southern tomato sandwich or tossing cherry tomatoes into a vibrant Caprese salad, homegrown tomatoes just hit different.

But what if there were a way to make your tomatoes even sweeter, your plants healthier, and your harvest bigger—all with something you already have in your kitchen? Spoiler: there is. And it’s probably sitting in your pantry right now.

Say Hello to Your New Garden MVP: Baking Soda.

Yes, that humble orange box you reach for when your fridge smells funky is also a secret weapon in the garden. When sprinkled lightly around your tomato plants, baking soda helps to lower the acidity of your soil. Why does that matter? Because less acidic soil = sweeter, less tart tomatoes. It's a small shift in pH, but it makes a big difference in flavor.

Here’s how to do it right: Start with about ¼ cup of baking soda sprinkled around the base of your seedlings, then water as usual. Do it again when your plants are about halfway to maturity. Already have a mature plant that's stingy with fruit? You can still apply baking soda—just be careful to keep it on the soil, not the leaves or stem.

Baking soda does more than flavor-boosting. It helps guard against fungus, which thrives in acidic environments, and can even stunt early-stage weeds trying to crowd out your tomatoes. And those annoying garden pests—aphids, ants, slugs? They’re not fans either.

Mix up a DIY garden spray with:

• 1 tbsp baking soda

• 1 tbsp vegetable oil

• A splash of dish soap

• 1 gallon of water

Spray your tomato plants as needed, and watch the bugs back off. Just don’t overdo it—too much baking soda can lead to salt buildup, which you definitely don’t want. Think of it as a sprinkle, not a soak.
