In addition to size, tomatoes have been bred for shape, texture, flavor, shelf-life, and nutrient composition, but it has been difficult to study these traits in tomatoes, because many of them are the result of many genes acting together. Domesticated tomatoes can be up to 1000 times larger than their wild relatives.
What determines tomato size?
The most common cause for small tomatoes is stressed plants. When plants are experiencing stressing circumstances, such as extreme drought or heat, insect infestation, or disease, they oftentimes stop sending their energy into flower or fruit production.

What causes tomatoes not to get big?
Tomatoes grow best at temperatures between 70 and 75 degrees Fahrenheit. If temperatures go above 85 to 90 degrees Fahrenheit, most tomatoes grow slowly or not at all, according to University of Davis.

Why are my tomatoes big but not red?
Tomatoes won’t turn red if it’s too hot (above 85F) or too cold (below 50F). This is probably the biggest culprit for most people, especially during a heatwave. Also, as tomato plants mature through the summer, they can become huge and overgrown.
How do you increase the size of tomatoes?
Maintaining a leaf area index of 3 will maximize fruit growth. Hand thinning of tomatoes on the end of a truss ensures more evenly sized, larger fruit. The use of growth regulators such as auxins at anthesis can stimulate fruit set, and increase fruit size especially under low light and low temperature conditions.
How do you make tomatoes bigger?
Use a premium potting soil mixed with a nutrient-rich organic amendment like worm castings or compost, (two-thirds potting soil to one-third amendment) and just one tomato per container, so the plant has plenty of room to grow.

How often should tomatoes be watered?

What does Epsom salt do for tomatoes?
Late in the season use an Epsom salt spray to increase tomato and pepper yield and keep plants green and bushy; early in the season add Epsom salt to the soil to aid germination, early root and cell development, photosynthesis, plant growth, and to prevent blossom-end rot.
How do I get my tomatoes to turn red?
The simplest way to try to turn those red is to bring the whole potted plant indoors, where it’s warmer. If you’ve got the space and the muscle, you can also uproot entire vines full of mature green fruit and hang them upside down from rafters in the garage or basement until fruits are red and ripe.

Should you cut the bottom leaves off tomato plants?
As the plants grow, revisit them regularly and keep the bottom 6 to 12 inches bared. Trim away these lower leaves and stems while they’re small, rather than letting them grow. This conserves the plant’s resources, and a smaller pruning wound creates less opportunity for disease to enter.
How often do you put Epsom salt on tomatoes?
once every six weeks
The ideal solution ratio is 1 tablespoon of Epsom salt per foot of plant height. If your tomato plant is two feet in height, you’ll be feeding it two tablespoons of Epsom salt at least twice a month! Once on the 15th and another on the 30th would be perfect. For other plants, the general rule is once every six weeks.
Should you top tomato plants?
Topping tomato plants can provide strength to weak, leggy plants. If you cut them back and allow them the opportunity to regrow, many times they grow back stronger. When the plants regrow, they may also come back sturdier in many cases. This allows them to support larger fruit without concerns of breaking.
What fertilizer is best for tomatoes?
