1. Variety
There are certain types of tomato varieties, which could not produce large tomatoes.
2. Water Insufficiency
Water insufficiency is another primary concern, which leads to the production of small tomatoes.
3. High Temperature
High temperatures may lead to the development of small-sized tomatoes even when there is a surplus of water.
4. Sunlight
Poor sunlight may lead to a lack of photosynthesis in plants, which may cause a deficit of energy for the growth of fruits.
6. Climate Change
Due to the increase in greenhouse gases, climate change can act as a drawback to fruits and vegetables like tomatoes.
Your Tomatoes Are Small Due to Lack of Water
Without enough water, your tomato plants will not be able to produce enough energy from photosynthesis. This lack of both energy and water prevents your plants from producing larger fruit.
Your Tomatoes Are Small Due to High Temperatures
When temperatures get too high in dry weather, a lack of water often follows, which we already covered. However, high temperatures can cause small tomatoes even when there is plenty of water for your plants.
Your Tomatoes Are Small Due to Lack of Sunlight
A lack of sunlight can also cause a lack of photosynthesis in plants, which leads to less available energy for growing fruit. According to the Ohio State University Extension, tomatoes prefer full sun, which means that they need at least 6 to 8 hours of sunlight per day.
Your Tomatoes Are Small Due to Lack of Pollination
Another possible cause of small fruit on tomato plants is a lack of pollination. According to the Mississippi State University Extension, you can tell you have poor pollination when you look inside fruits and see a low seed count.

Tomatoes are ripening way too small
This is my first attempt at growing tomatoes but something isn't right. I'm using E.B. Stone soil and fertilizer and I have several large organic varieties in separate containers. I'd say the pots are 12-15 inches tall and about 12-15 inches wide at the top. The problem I'm having is that the tomatoes aren't getting as big as they should be.
Comments (40)
Size of fruit is mostly determined by the genetics of the plant variety. So we need to know the names of the varieties you are growing please.
1. Blossom End Rot
What it looks like: The tomato plants appear healthy, but as the tomatoes ripen, an ugly black patch appears on the bottoms. The black spots on tomatoes look leathery. When you try to cut off the patch to eat the tomato, the fruit inside looks mealy. What causes it: Your plants aren’t getting enough calcium.
2. Blossom Drop
What it looks like: Flowers appear on your tomato plants, but they fall off without tomatoes developing. What causes it: Temperature fluctuations cause blossom drop. Tomatoes need night temperatures between 55 to 75 degrees F in order to retain their flowers. If the temperatures fall outside this range, blossom drop occurs.
3. Fruit Cracks
What they look like: Cracks appear on ripe tomatoes, usually in concentric circles. Sometimes insects use the cracks as an opportunity to eat the fruit, or birds attack cracked fruit. What causes them: Hot, rainy weather causes fruit crack. After a long dry spell, tomatoes are thirsty.
4. Sunscald
What it looks like: The plants look healthy, and the fruit develops normally. As tomatoes ripen, yellow patches form on the red skin.
5. Poor Fruit Set
What it looks like: You have some flowers but not many tomatoes. The tomatoes you do have on the plant are small or tasteless. What causes it: Too much nitrogen in the soil encourages plenty of green leaves but not many flowers. If there aren’t enough flowers, there won’t be enough tomatoes.
6. Catfacing
What it looks like: Catfacing makes tomatoes appear deformed. The blossom end is rippled, bumpy and lumpy. What causes it: Plants pollinated during cool evenings, when the temperatures hover around 50 to 55 degrees F, are subject to catfacing. Blossoms fall off when temperatures drop too low.
7. Leaf Roll
What it looks like: Mature tomato plants suddenly curl their leaves, especially older leaves near the bottom. Leaves roll up from the outside towards the center.
Why Are My Beefsteak Tomatoes Small?
Finding small, unattractive tomatoes on the vine can be frustrating. If your beefsteak tomatoes aren’t growing to their optimal size, there could be a bunch of factors responsible for the problem. Since most of them are environmental factors that result in small tomatoes, they can easily be rectified to obtain the optimal size you’re hoping for.
1. Root Damage
You need to be very careful when transplanting the seedlings into your garden. These delicate plants have even delicate roots. Pull the plant out gently from its original container, making sure the gardening tools don’t break or damage the roots in the process.
2. Mislabeled Seeds
Different varieties of tomatoes produce different sizes of tomatoes. It could be that the seed labelled “beefsteak tomatoes” that you bought from the nursery isn’t beefsteak after all. A friend called me up and asked me why are my beefsteak tomatoes so small? After looking over them it was clear they were not beefsteak tomatoes.
3. Lack Of Water
Tomatoes are 95% water. You can’t expect those plump, juicy fruits when you’ve not given them enough to drink. They need plenty of water, one or two deep waterings per week, to keep the plants from damage.
4. High Temperature
Small beefsteak tomatoes are a common complaint of gardeners living in the Southeast. The hot and humid climate of the region, especially from late spring to early fall, can be challenging for the plants.
5. Too Much Nitrogen
Over-fertilization is often the cause of small beefsteak tomato fruits. Gardeners often overdue fertilization, thinking it will benefit the plants. However, very often, it creates the opposite effect.
6. Excess Suckers
As tomato plants develop, they produce tiny branches called suckers between the main stem and branches. These suckers grow into branches, producing more suckers as they develop. Many gardeners like to pinch out the suckers to keep the number of branches per plant to a minimum.
