11 Clever Ways To Use Baking Soda In Your Garden

Baking soda is one of those household supplies that has a million uses. It can be used around the home for various purposes ranging from cleaning to cooking to odor removal. You’ll be glad to know that it has several uses outside the home as well.

If you like to garden, baking soda could be your new best friend! Here are some ways it can help.

1. Find Out Soil pH

Soil pH is an important factor of soil health

Preparing your soil and checking it regularly is an important part of keeping your plants healthy. The right pH is a great way to start. Since baking soda is alkaline it can act as a makeshift indicator. Here’s how:

  • Take a sample of soil and make it slightly muddy.
  • Pour some baking soda into it.
  • If the mixture starts to bubble, your soil is acidic.
  • Alternatively, if you pour vinegar into your soil and it starts to bubble, the soil is more alkaline.

2. Suppress Odor From Compost
