Baking soda is often seen as a simple kitchen staple, but it holds a secret power in the garden.

I’ve found it to be a gardener’s best companion, offering easy solutions to common gardening problems.

From fighting pests to sweetening tomatoes, baking soda has become my go-to for keeping my garden healthy and thriving.

#1. Baking Soda as a Natural Fungicide

This simple kitchen staple can be a game-changer for tackling fungal diseases in your garden.

Safe to use around edible crops, baking soda helps prevent issues like powdery mildew and black spot fungus.

I usually mix one tablespoon with a gallon of water for a spray, adding a bit of castile soap for better adhesion.

#2. Enhancing Soil pH

If your soil is too acidic, it can hinder plants that thrive in neutral or alkaline conditions.

To test, you just mix some soil with water to make it muddy, then sprinkle baking soda on top, if it fizzes, your soil is acidic.

To fix this, you sprinkle baking soda over the soil, work it in, and water thoroughly.

This simple trick, especially around tomato plants, can reduce acidity and even sweeten your tomatoes!

#3. Natural Pest Control

Pesky bugs munching on your plants can be a real headache, but baking soda can be your secret weapon!

You just mix a tablespoon of baking soda with a gallon of water and a few drops of dish soap, and you’ve got a natural insect repellent.

I’ve tried this in my garden, and it works wonders, especially against aphids and spider mites, without harming beneficial insects like ladybugs.

#4. Improving Plant Growth

As I have shared, baking soda can raise the pH level of acidic soil and acts as a mild fungicide

As a result, it helps combat powdery mildew and promote healthier growth. However, use it sparingly -too much can harm your plants, so a little goes a long way.

#5. Cleaning Garden Tools and Pots

Simply mix baking soda with water to make a paste, and scrub away. Your tools will sparkle in no time.

It’s gentle, so no worries about damaging your favorite trowel or painted terracotta pots.

Plus, it easily removes stubborn stains and mineral deposits, leaving your pots looking brand new.

#6. Deodorizing Compost and Garden Areas

Ever walked past your compost pile and thought, "What died in there?" Composting is great for the garden, but the smell?

Luckily, baking soda can save the day. Just like it neutralizes fridge odors, it can do the same for your compost and garden areas.

You just sprinkle a bit on smelly compost to balance pH levels and neutralize odors - just don’t overdo it.
