Help Keep the Critters Away

If you want to keep bugs and pests away from your garden without applying chemical pesticides, use baking soda instead.

Baking soda can also be used to reduce the ant population around your home if you are having difficulties with ant infestations. Simply mix five teaspoons of baking soda with five teaspoons of confectioner’s sugar and one tablespoon of water. Pour this mixture on any anthills you find, and add a little bit of vinegar. The sugar will attract the ants, but the baking soda and vinegar will be fatal to them.

Get Rid of Fungus, Mildew, and Weeds 

Baking soda can be used to make an effective fungicide, if you live in a damp climate and struggle with fungus growing on your plants. Four teaspoons of baking soda mixed into one gallon of water can be applied to problem areas to get rid of any fungus growing in your garden.

This approach also works well against mildew. Mix one tablespoon of baking soda with 2.5 tablespoons of horticultural oil and one gallon of water, and spray the mixture on your plants, particularly fruits and vegetables, to give them a protective layer against mildew.

If weeds are a problem, particularly those pesky crab grasses that grow between the cracks in your walkways, all you have to do is moisten the area and apply a thick layer of baking soda so that it forms a thick paste. Sweep the paste into any cracks that exist, and you will get rid of those weeds once and for all.

Treat your Compost and Test your Soil

If you’d like to know what the pH of your soil is, there’s an easy way to test it without having to purchase a pH kit. First, have half a cup of baking soda and half a cup of vinegar ready. Then, get two samples of soil and place them into separate containers. Pour your vinegar into one of the samples, and watch if it bubbles. If it does, that means the pH of the soil is above seven, and therefore alkaline. If it doesn’t, take your other sample and add baking soda with half a cup of water. If it bubbles this time, that means that the pH is below seven, and therefore somewhat acidic.

If you are using your own compost in an effort to be more environmentally friendly, you are most likely familiar with the intense odor that it can produce. To help decrease the smell, sprinkle a little bit of baking soda on top of the pile. Be careful not to put on too much, however, as you could risk slowing down the decomposition process.

A Better Solution

If you are looking for ways to improve your garden this spring and summer, but are fed up with having to use synthetic chemicals to control pests and increase yields, try using baking soda. It’s inexpensive, easy to find, and is much safer for your health and the health of your garden.
