How To Increase Tomato Fruit Size?

The tomato is a perennial plant that can grow to be as tall as 10 feet but often it is grown as an annual. It does need plenty of sun and water to grow well. If you want your tomato plants to produce bigger fruit, then follow these tips:

Provide adequate nutrition through fertilization, irrigation, and soil improvement.

As with any plant, tomatoes require adequate nutrition through fertilization, irrigation and soil improvement.

Fertilizer is a key component of the gardening process since it provides nutrients for your plants and boosts their growth rate.

Irrigation water is important because it helps control weeds in the garden and improves nutrient uptake by the soil, which can increase tomato growth rates.

Soil improvement involves adding amendments such as compost or peat moss that encourage healthy root development and help prevent diseases from spreading through your soil ecosystem.

Cut off suckers that develop.

Suckers are shoots that grow from the stem and can be removed for bigger fruit. They are not necessary, so if you notice them growing, cut them off with your fingers or a knife.

Prune the plant to increase yield.

  • Prune out damaged branches. This is a great way to get your tomato plants to produce more fruit and larger fruits. Just be sure you don’t prune too much, or it could cause the plant to go into shock.
  • Prune out branches that are shading the fruit buds from getting sunlight as they grow, which will result in smaller yields and lower quality tomatoes overall.
  • Remove branches that are competing with each other for nutrients, water, or sunlight (such as those growing near another plant).

Prune out damaged branches.

  • Prune out damaged branches. Plants are susceptible to a lot of stressors, including insects and disease, so it’s important to keep your tomato plants healthy by pruning them regularly. You can do this by cutting off all of the damaged branches that were growing on top of each other or touching any nearby plants or structures (like fences).
  • Remove branches that are touching the ground too deeply—you don’t want those exposed roots getting in contact with water runoff from rainstorms! And if you’ve got more than one plant growing near each other in close proximity—say two houses back-to-back—then make sure they aren’t intertwined enough so as not to cause problems later down the line when there might be some heavy winds blowing.

Remove any leaves that shade the fruit.

To ensure that your tomatoes receive optimal sunlight, remove any leaves that shade the fruit. This includes any branches or leaves that are diseased or damaged. You should also make sure to remove any leaves blocking airflow to the fruit as this will cause them to rot faster and have fewer nutrients for growth.

Provide plenty of calcium for strong cell division in the fruit.

Calcium is important for cell division. It’s also necessary for fruit development and growth, which is why it’s one of the most common nutrients that gardeners add to soil.

In addition to being a building block for vegetables and other plants, calcium helps prevent blossom end rot in tomatoes by strengthening cell walls. This makes them more resistant against harmful bacteria such as Botrytis cinerea (gray mold) or Fusarium oxysporum.

For best results: Add 1/4 cup per gallon of water when watering your tomato plants regularly throughout their growing season.

Do not use more than 1/2 teaspoon per gallon because too much can cause excess salts buildup on leaves or stems which could inhibit nutrient absorption by roots during times when they need it most like after heavy rains or flooding occurs near where you live now do this every few weeks until mid-summer.

Follow these steps to increase tomato fruit size

  • Provide adequate nutrition through fertilization, irrigation, and soil improvement.
  • Cut off suckers that develop.
  • Prune the plant to increase yield. Remove any leaves that shade the fruit and provide plenty of calcium for strong cell division in the fruit


There are many factors that play a part in how much a tomato plant produces. The most important of those factors is the amount of sunlight it receives.

Tomato plants grown indoors will produce more than those that are grown outdoors due to their lack of exposure to sunlight.
