5 Ways Baking Soda Can Help Your Tomato Plants Grow Better (& 3 Ways It Doesn’t)

Baking soda is often touted as a natural way to help plants grow. And while it’s true that this humble household ingredient can do wonders for your plants, it’s important to understand how and when to use it.

Here are five ways baking soda can help your tomato plants (& 3 ways it doesn’t)

1. Baking soda can help prevent blossom end rot.

Blossom end rot is a common problem for tomato growers. It’s caused by a lack of calcium in the fruit, and results in ugly, brown spots on the bottom of the tomato. While there are a number of ways to prevent blossom end rot, one of the simplest is to add a little baking soda to the soil.

Just be sure not to add too much, as too much baking soda can actually be harmful to plants.

2. Baking soda can help deter pests.

Many gardeners swear by using baking soda to deter pests. While there is no scientific evidence to support this claim, some gardeners believe that the alkalinity of baking soda confuses or repels pests.

If you’re dealing with a pest problem, it might be worth giving baking soda a try. Just be sure to start with a small amount, and increase it gradually if necessary.

3. Baking soda can help balance the pH of your soil.

Tomatoes prefer slightly acidic soil, with a pH between 6.0 and 6.8. If your soil is too alkaline, your tomatoes may not be able to take up nutrients properly. Baking soda can help to raise the pH of your soil, making it more acidic and ideal for tomato plants.

4. Baking Soda Can Help Prevent Powdery Mildew

Powdery mildew is a common problem for tomato plants. But there’s a simple solution – baking soda! Just mix 1 teaspoon of baking soda with 1 quart of water, and spray your plants weekly. The baking soda will help to prevent powdery mildew from forming.

5 . Baking soda can provide a boost of nutrients.

In addition to helping with pH balance, baking soda is also a source of important nutrients for plants, like calcium and magnesium. These nutrients can help to promote healthy growth and fruiting in tomatoes.

When used in the garden, baking soda can help:

-Increase nutrient uptake

-Improve overall growth

-Protect plants from pests and diseases

3 Baking Soda Uses That Don’t Work

Below we have listed some of the common baking soda uses that people think work, but actually don’t.

1. Makes Tomatoes Sweeter

Baking soda is often touted as a natural way to sweeten tomatoes, but unfortunately, this is one use that simply doesn’t work. Baking soda is a base, and when added to tomatoes, it will actually make them more acidic. So, if you’re looking for a way to sweeten your tomatoes, you’ll need to look elsewhere.

2. Improves Flowering

If you’re wondering whether adding baking soda to your soil will help your tomato plants flower, the answer is probably not.

Sodium deficiencies are very rare, and adding too much baking soda to the soil is actually toxic to plants. Plus, sodium is a micronutrient, which means it plays a relatively minor role in the overall health of your tomatoes.

If you’re concerned about providing the right nutrition for your plants, the best approach is to fertilize them regularly with the appropriate fertilizer.

3. Kills Weeds

We all know that baking soda is a great household cleaner. But did you know that it can also be used to kill weeds? Well, it turns out that baking soda doesn’t actually kill weeds. In fact, it can actually make them grow faster!

So, if you’re looking for a natural weed killer, you might want to try something else.

Although it has its benefits, baking soda won’t help:

– Make your tomatoes taste sweeter

-Improve overall flavor of your tomatoes

– Kill weeds around your tomato plants
