You can use various sprays on your tomato plants. Whichever you choose, remember to not over mist them. Too much water can cause mold, but spraying your plants every now and then can be good for them. Here are some reasons to do this:

It Can Keep Your Plants Healthy

Some sprays are formulated to keep your tomato plants healthy. They create a protective layer to prevent dehydration and contain many nutrients to ensure optimal growth.

Reasons To Spray Your Tomato Plants

It Can Prevent Diseases

Many tomato plant diseases can make the fruit inedible. There’s no cure for these, so prevention is best. 

Before these diseases get a chance to infect your plants, spray them! Many sprays are formulated to protect your tomato plants against diseases by killing any germs or viruses trying to infect them.

It Can Set The Blossoms

Sometimes when night temperatures are extremely cold, tomato plant flowers fall off before they blossom. This means that they don’t carry any fruit. 

You can buy a blossom set spray that will help with fertilization. The flowers will blossom before they have a chance to fall off.

Insects, worms, and bugs are a huge issue when growing tomato plants. Tomato hornworms and tomato fruitworms eat through the fruit and leave large holes.

Qualities Of A Good Tomato Plant Spray

No Danger Or Warning Labels

The right spray for your tomato plants won’t have any danger or warning labels. Always use a spray that doesn’t make your tomatoes toxic to animals or humans. 

The Insect Causing Trouble On The Label

The target insect should be on the label if you’re looking for the right pesticide. Fly repellent wouldn’t be effective in killing mites – just so the right spray is needed for the pests you’re targeting on your tomato plants. 

Environmentally Friendly

The only spray you should ever use is one that’s as good for the environment as it is for your tomatoes. It shouldn’t contain ingredients that can harm the planet.

Nutritional Ingredients 

A good tomato plant spray has all the proper nutrients your tomatoes need to thrive. A store-bought misting spray should have all this information on the label. You should look for a spray containing calcium, potassium, phosphorus, and nitrogen.

The #1 Best Spray For Tomato Plants

You can DIY a tomato misting spray if you prefer this option. Here are three of my favorite ones, ranked!

#1 Best Spray For Tomato Plants – Epsom Salt Spray

The number one spot goes to an Epsom salt spray. This spray contains essential nutrients like sulfur and magnesium. You only need to spray your tomatoes once a month with this mixture. 

It gives you strong and healthy plants with large, juicy tomatoes. You can even use it on fruits that are struggling to ripen. 

Add a teaspoon of Epsom salt to a quarter gallon of water, and spray away!

#2 Best Spray For Tomato Plants – Aspirin Spray

Science proves that aspirin may be the answer to your tomato-plant prayers! 

A mix of aspirin and water can increase the number of tomatoes you harvest, prevent diseases, and give your plants a fighting chance during high temperatures and drought.

#3 Best Spray For Tomato Plants – Milk Spray

In third place is a spray made with something you keep in your fridge!

Mixing milk powder or skim milk with water produces a whitish spray that prevents fungal diseases. It also gives your tomato plants some much-needed calcium. 

You can use this spray once a week.

Before You Start Misting

Misting your tomato plants daily might seem like a good idea to keep pests and fungi away, but it isn’t. Adding too much moisture to this fruit can create mold and stunt growth. You should find a misting spray that works effectively when only used once weekly or biweekly.

The best sprays for tomato plants are often those you make yourself. There’s no need to spend hundreds of dollars on store-bought pesticides. You can mix an effective concoction with a few things you might already have at home.
