Did You Know?
1. Did you know that the ideal number of tomato plants per square foot is five? This spacing allows each plant enough space to grow and receive adequate air circulation and sunlight.
2. Tomato plants release a chemical called methyl jasmonate when they are damaged, which serves as a signal to nearby plants to increase their defense mechanisms. This means that when one tomato plant is attacked by pests, it can alert its neighboring plants to prepare for potential threats.
3. The technique of planting tomatoes close together in small spaces, known as intensive or square foot gardening, was popularized by horticulturist Mel Bartholomew in the 1980s. He developed this method as a way to maximize productivity in small gardens while minimizing effort and resources.
4. One square foot of space can yield an impressive amount of tomatoes if proper care is provided. In ideal conditions, a single tomato plant confined to a one-square-foot area can yield up to 10 pounds (4.5 kilograms) of tomatoes over the course of a growing season.
5. The tradition of planting tomatoes in square foot gardens can be traced back to ancient Aztec civilizations. They utilized a method called “chinampa,” where they created floating gardens on rafts made of intertwined reeds in Lake Tenochtitlan. These floating gardens were divided into square-foot sections and used to grow a variety of crops, including tomatoes.
General Guidelines For Tomato Plant Spacing
Tomatoes are a staple in many home gardens, prized for their delicious flavor and versatility. To ensure the healthy growth and maximum yield of your tomato plants, proper spacing is crucial.
- When planting tomatoes in containers, it is important to consider the size of the variety. Compact/small tomato varieties should be spaced around 12 to 18 inches between plants. Larger tomato varieties, on the other hand, can be spaced from 18 to 36 inches or more depending on the type and varietal. For container gardens, one tomato plant per pot with a diameter of 14 inches and at least five gallons in volume is ideal.
- In traditional row gardens, tomato plants should be spaced 12 to 48 inches apart, with rows spaced 3 to 4 feet apart. Smaller tomato varieties like cherry tomatoes can be planted closer together, typically 12 to 18 inches apart.
- Raised beds offer more flexibility when it comes to spacing. Tomato plants in raised beds should be spaced 18 to 24 inches apart.
-
For those practicing square foot gardening, one tomato plant per square foot is recommended. Square foot gardening is a technique developed by Mel Bartholomew in the 1980s that yields more produce, in less space, using less water, and requiring less care. This method allows for maximum utilization of available space and ensures optimal plant density.

Spacing For Determinate And Indeterminate Tomato Varieties
Another factor to consider when determining tomato plant spacing is whether the variety is determinate or indeterminate. Determinate tomato varieties have a more compact growth habit and tend to grow to a predetermined height, usually around 3 to 4 feet. For determinate varieties, it is recommended to space the seeds 1.5 to 2 inches apart and leave 2 to 3 rows between plants.
Indeterminate tomato varieties, on the other hand, have a vining growth habit and can grow indefinitely until frost or pruning. These varieties should be given more space to accommodate their sprawling nature. Indeterminate tomato plants should be spaced at least 18 inches apart, but ideally 3 to 4 feet apart. This extra space allows for proper air circulation, which helps prevent diseases and promotes healthy growth.
Ideal Spacing For Different Sizes Of Tomato Varieties
Tomatoes come in various sizes, from smaller cherry tomatoes to large beefsteak tomatoes. Each size has its own ideal spacing requirements.
-
Compact/small tomato varieties, including cherry tomatoes, should be planted closer together, around 12 to 18 inches between plants. This allows for the compact growth habit of these varieties and maximizes the use of space.
-
For larger tomato varieties, such as beefsteak tomatoes, it is recommended to space them from 18 to 36 inches or more depending on the specific type and cultivar. These larger plants require more space for their extensive root systems and to ensure proper air circulation. Adequate spacing also reduces competition between plants and promotes healthy growth and fruit production.
Remember to give the plants enough space to thrive!
Tomato Plant Spacing In Different Garden Settings (Rows, Raised Beds, Containers)
The spacing of tomato plants can vary depending on the garden setting. In traditional row gardens, tomato plants should be spaced 12 to 48 inches apart, with rows spaced 3 to 4 feet apart. This spacing allows for easy access to each plant for watering, pruning, and harvesting.
Raised beds offer more flexibility in spacing. Tomato plants in raised beds should be spaced 18 to 24 inches apart. The raised beds provide improved drainage and soil quality, allowing for closer planting without compromising plant health.
In container gardening, the size of the container plays a significant role in determining the spacing. For pots and hanging baskets, small containers require 6 to 8 inches of spacing between plants, while larger pots need 12 to 15 inches. This spacing ensures that each plant has sufficient space to grow and access to adequate nutrients and water.
Importance Of Proper Spacing For Tomato Plant Health And Fruit Production
Proper spacing of tomato plants is essential for their overall health and fruit production. When tomato plants are adequately spaced, they have access to sufficient light, water, and nutrients. Proper air circulation between plants helps prevent the spread of diseases and enhances plant health.
In addition to promoting plant health, proper spacing also helps maximize fruit production. When tomato plants are overcrowded, they compete for resources, resulting in smaller yields and smaller-sized fruits. By providing each plant with enough space, you allow them to grow to their full potential, producing larger and more abundant fruits.
The optimal spacing for tomato plants depends on various factors such as the type of tomato variety, the size of the plant, and the garden setting. General guidelines recommend spacing tomatoes 18 to 24 inches apart. Determinate and indeterminate tomato varieties have specific spacing requirements, with indeterminate varieties requiring more space for their sprawling growth habit. The size of the tomato varieties also plays a role, with compact varieties needing closer spacing and larger varieties needing more space. Whether you plant in rows, raised beds, or containers, it is important to ensure each plant has enough space to access light, water, and nutrients. Proper spacing not only promotes plant health but also maximizes fruit production. So, next time you plan your tomato garden, remember to consider optimal spacing for the best results.
