Cautionary Notes on Using Baking Soda Near Desirable Plants

While baking soda proves itself to be a formidable weed control agent, caution is critical when applying it in proximity to plants you want to thrive.

Consider the following notes:

Selective Application

Apply baking soda-based weed killers with precision, targeting only the unwanted vegetation.

Use protective barriers like cardboard or plastic sheets to shield desirable plants during application. 

Applying the Right Amount

Baking soda, when used excessively, can alter the pH of the soil, impacting plant health.

Use sparing amounts and monitor the reaction of desirable plants closely.

Strategic Application Timing

Apply the weed killer when desirable plants are less vulnerable, such as during dormant seasons. Avoid application during the active growth phase of plants you wish to protect.

Before widespread application, conduct a small-scale test in a controlled area to observe the impact on surrounding plants. Adjust the concentration or application technique based on the results of the test.

4. Soil pH Adjustment

Baking soda isn’t just a kitchen magician; it’s also your ally in cultivating sweeter, more robust tomatoes. 

Here’s how to use it to adjust soil pH for the perfect tomato harvest:

Identifying pH Imbalance

Test your soil to determine its pH level, especially if your tomatoes aren’t reaching their flavor potential. Tomatoes typically thrive in slightly acidic to neutral soil (pH 6.0 to 7.0).

Start with about a tablespoon of baking soda per plant for small tomato plants. Larger plants may require up to two tablespoons.

Sprinkle the calculated amount of baking soda around the base of each tomato plant.

Work the baking soda into the topsoil without damaging the plant’s roots.

Monitoring and Adjusting

Monitor the soil pH regularly, adjusting the baking soda application to maintain the desired pH level.

Aim for a gradual adjustment to prevent sudden pH shifts.

Guidelines for Neutralizing Soil pH in Acidic Areas

Baking soda isn’t just for sweetening tomatoes but also for neutralizing soil acidity. 

Follow these guidelines to balance the pH in areas where acidity is a persistent issue:

• Soil pH Testing: Conduct a thorough soil pH test to determine the extent of acidity. Baking soda is particularly effective in slightly acidic to moderately acidic soils.
• Calculation for Neutralization: Determine the amount of baking soda needed based on the severity of soil acidity. Start with a modest application, such as 5-10 pounds of baking soda per 100 square feet.
• Even Distribution: Spread the calculated baking soda evenly over the soil surface. Use a rake or garden fork to incorporate the baking soda into the top layer of the soil.
• Watering Considerations: Water the area thoroughly after applying baking soda to aid its absorption into the soil. Reapply as needed, keeping a close eye on pH levels over time.

5. Cleaning and Maintenance

Harness the cleaning prowess of baking soda to revive your garden tools, removing dirt and preventing rust. 

Simple Baking Soda Solution

1. Mix 1 part water to 3 parts baking soda to create a paste suitable for cleaning and rust removal. 
2. Adjust the paste’s consistency as needed, ensuring it adheres to the surface of your tools.
3. Apply the baking soda paste to the surfaces of your garden tools, concentrating on areas with rust or stubborn grime.
4. Scrub the tools with a brush or an old toothbrush to remove the debris.
5. Rinse the tools thoroughly with water to remove the baking soda residue.
6. Dry the tools completely to prevent future rusting.

Odor Control in Compost Piles Using Baking Soda

Baking soda comes to the rescue to neutralize these smells. Sprinkle a handful of baking soda over your compost pile periodically. Focus on areas with strong odors or where decomposition is most active.

Incorporate baking soda into the compost layers as you build or turn the pile. Ensure even distribution to maximize its odor-neutralizing effects.

After a day of tending to your garden, the last thing you want is to be greeted by unpleasant odors lingering in your trusty garden gloves. Luckily, the solution is as simple as reaching for your kitchen cupboard—baking soda. 

Here’s a quick and effective way to keep your garden gloves fresh and ready for action:

What You’ll Need

• Baking soda
• Garden gloves

Instructions

1. Before deodorizing, make sure your garden gloves are dry. If damp from sweat or moisture, allow them to air dry thoroughly.
2. Sprinkle a generous amount of baking soda inside each glove. Aim for an even distribution, covering the interior surfaces where your hands come into contact.
3. Give the gloves a good shake to help distribute the baking soda evenly. For added effectiveness, rub the baking soda into the fabric or leather of the gloves.
4. Allow the baking soda to sit inside the gloves for a few hours or overnight. This gives it time to absorb moisture and neutralize odors.
5. Before wearing the gloves again, shake out any excess baking soda. You can also turn the gloves inside out and give them a gentle shake to remove the powder.
