Here is how you can put this budget-friendly staple to work in your backyard today.
Say Goodbye To Powdery Mildew
A quick spray of baking soda mixed with a drop of dish soap stops fuzzy white fungus from ruining your zinnias. This simple trick keeps your flower beds looking professional without the heavy chemical smell.
Ratio Mix: Mix 1 tablespoon of baking soda and ½ teaspoon of liquid dish soap into 1 gallon of water. Spray lightly on the affected foliage early in the morning.
Sweeten Your Tomato Harvest
Lightly sprinkling baking soda on the soil around the base of your plants helps lower acidity. This results in much sweeter tomatoes that will be the star of your next summer BBQ.
Ratio Mix: Lightly sprinkle about 1 to 2 tablespoons of dry baking soda evenly on the soil around the base of each tomato plant (avoiding the stem) once every month during the growing season.
Natural Weed Control Between Pavers
Poured directly into the cracks of your patio or driveway, baking soda acts as a natural desiccant to shrivel up messy weeds. It is a fast way to boost your curb appeal without a full day of pulling by hand.
Ratio Mix: Dissolve 2 tablespoons of baking soda in 1 gallon of warm water. Use this solution to scrub your empty clay or plastic pots, then rinse thoroughly.
Keep Your Potted Plants Fresh
A monthly rinse with a soda solution prevents musty smells and mineral buildup on your containers. It keeps your clay and plastic pots looking brand new for every season.
Ratio Mix: Add ¼ teaspoon of baking soda to 1 quart of fresh vase water to keep the water clear and prolong the life of your blooms.
Refresh Your Cut Flowers
Adding a tiny pinch of baking soda to your vase water prevents bacteria and keeps flowers vibrant for much longer. Your kitchen table centerpieces will stay fresh and beautiful all through the week.
Ratio Mix: Sprinkle a continuous, 1-inch wide ring of dry baking soda directly on the soil around the perimeter of vulnerable plants. Reapply after a heavy rain.
Deter Pests Without Harsh Chemicals
Slugs and ants hate the texture and alkalinity of baking soda. Creating a thin white perimeter around your favorite plants acts as a safe, invisible fence against creepy crawlies.
Ratio Mix: Mix 3 parts baking soda to 1 part water in the palm of your hand to create a thick, gritty paste. Scrub for 30 seconds, then rinse clean.
Clean Dirty Garden Hands
Mixing baking soda into a paste with water creates a natural abrasive that scrubs away deep dirt and stains. It is the perfect way to clean up after a long Saturday of heavy lifting in the dirt.
Ratio Mix: Mix 3 parts baking soda to 1 part water in the palm of your hand to create a thick, gritty paste. Scrub for 30 seconds, then rinse clean.
Test Your Soil Acidity At Home
Sprinkle a little baking soda on a damp soil sample to see if it fizzes. If it bubbles, you have acidic soil, giving you a free and easy way to plan your next planting.
Ratio Mix: Collect ½ cup of soil from your garden, moisten it with distilled water until it’s muddy, and sprinkle ½ cup of dry baking soda on top. If it fizzes, your soil is acidic!
Brighten Up Your Hydrangeas
Watering your hydrangeas with a baking soda mixture helps keep the soil alkaline. This ensures your pink petals stay bright and saturated rather than fading into a muddy color.
Ratio Mix: Dissolve 1 tablespoon of baking soda in 1 gallon of water. Use this mixture to water the base of your pink hydrangeas once a month during spring and summer to maintain that vibrant pink hue.
Deodorize Your Compost Pile
A quick sprinkle of baking soda over the top of your compost pile neutralizes smells instantly. It is a smart way to keep your project hidden and avoid any complaints from the neighbors or the HOA.
Ratio Mix: Sprinkle 1 cup of dry baking soda evenly over the top layer of your compost bin every few weeks, or whenever you notice a sour smell starting to build up.
