Number One Technique to Produce Sweeter Tomatoes

Phosphorus is the Key Element that Directly Results in Sweeter Tomatoes! 

Fertilization, in a proper ratio, plays a crucial role in making tomatoes sweeter. According to research, enhanced fertilization, with a higher phosphorus rating, has a significant effect on tomato quality, color, sweetness, and taste.

According to an article by the University of Missouri, phosphorus and potassium have favorable effects on fruit acid and sugar content. “The number one secret to growing sweeter tomatoes is having more phosphorus in the soil.”

Another study indicates that increasing the rate of potassium in the growing medium while cultivating tomatoes results in tissue redness, firmness, crispness, and more acidic flavor.

Remember that tomato variety, degree of ripeness, and proper sunlight exposure in the right proportion also play a vital role in producing flavorful and sweet tomatoes.

Using a fertilizer that is high in phosphorus can give you sweeter tomatoes!

Why Tomato Plants Require Phosphorus?

Phosphorus is necessary for the overall plant growth, formation of blooms, and flowers. It assists in building cell membranes and storing energy. The tomatoes’ sweetness, size, and color depend primarily on the phosphorus content in the growing medium.

Effects of Phosphorus Deficiency on Tomatoes

• Stunted or spindly growth.
• Flower and buds drop or unripe fruit.
• More petite and bitter tomatoes.

Natural Sources of Phosphorus for Tomatoes 

Instead of applying inorganic, commercial fertilizers, it’s best to try these natural sources for sweeter and better tomatoes. Because using too many commercial fertilizers rich in phosphorus may also toxify your soil. 

• Bone Meal: It is an excellent source of phosphorus (18-24%) and nitrogen (0.7-7%). This is what you should use for sweeter tomatoes.
• Neem Cake: Add 2-4 tablespoons of neem cake to the tomato at the time of planting as it is rich in phosphorus, nitrogen, and potassium. It also keeps the plant free from pests and fungal attacks while making sure it blooms for long.
• Banana Peel Fertilizer: It is another great source of phosphorus and results in healthy growth with sweeter tomatoes.
• Rice Water: It contains up to 45-50% phosphorus. Read more about its scientifically-proven benefits here.

Note: If you use commercial fertilizer to produce sweet tomatoes, go for a 6-24-24 or 8-32-16 blend. Although, don’t overuse it.

Should You Perform a Soil Test Before Feeding Tomatoes?

If you plan to grow tomatoes in large quantities or in the entire garden, then performing a soil test will give you the right idea about the nutrients present in the soil. You can then add phosphorus or other minerals accordingly to boost growth and sweetness.

If growing extensively and you apply fertilizer without examining your soil, it may cause an asymmetry of nutrients in the entire crop. We have a great article on how to do soil tests easily at home here. Also, there are many soil NPK testing kits available in the market or online; you can try them to find out the deficiency.

Note: If you are growing tomatoes in pots or a small vegetable patch, then you can skip the soil test if you want.
