6. Repel Pests Without Chemicals
Baking soda can be used to deter ants, roaches, and cabbage worms without harming beneficial insects like bees or butterflies.
Mix equal parts baking soda and flour
Dust around affected plants or garden entry points
Safe for edible gardens and pet-friendly when used responsibly.
7. Deodorize Compost and Trash Bins
Got a smelly compost pile or garden waste bin? Baking soda neutralizes odors without interfering with decomposition.
Sprinkle a handful over the top layer every week
Helps balance pH and control acidity in compost
Bonus: Keeps pests away from the bin!
8. Boost Your Garden Tool Cleaning Routine
Rusty, dirty tools can transfer diseases to your plants. Baking soda helps remove grime and disinfect gardening tools easily.
Make a paste with baking soda and water
Scrub tools with a brush, rinse, and dry thoroughly
Add a little vinegar for rust removal.
9. Prevent Fungus on Cucumbers and Squash
Squash and cucumber leaves are highly susceptible to fungus. Using a baking soda spray regularly can prevent infections from taking hold.
Mix 1 tbsp baking soda + 1 tsp horticultural oil + 1 gallon water
Spray leaves every 7–10 days
Always spray early in the morning to avoid sunburned leaves.
10. Neutralize Acidic Soil Naturally
Some flowering plants—like lavender, lilac, and clematis—struggle in acidic soil. Use baking soda as a mild alkaline amendment to raise soil pH naturally.
Test your soil pH first
Add 1 tablespoon baking soda per gallon of water and apply around plant roots
Repeat monthly if needed
Always monitor soil with a test kit to avoid over-alkalizing.
Bonus Tip: Use Baking Soda for Indoor Plants Too!
Baking soda can benefit indoor houseplants as well. Use a diluted mix (¼ teaspoon per quart of water) to:
Clean dusty leaves
Deodorize soil from overwatering
Keep small pests away (like fungus gnats)
Just avoid applying directly to delicate or sensitive species without testing first.
Baking soda is one of the most versatile, affordable, and eco-friendly tools in any gardener’s toolkit.
From promoting beautiful blooms to protecting your plants from fungi and pests, it’s a simple ingredient with big benefits.
Whether you’re growing vibrant flowers, juicy tomatoes, or healthy houseplants, using baking soda wisely can enhance your gardening success while avoiding harsh chemicals.
