Why Tomato Plant Spacing Matters

Good tomato plant spacing is not just about neatness. It affects the health and yield of every plant:

• Airflow: leaves dry faster after rain or dew, which reduces early blight, leaf spot and other fungal diseases.
• Sunlight: each plant gets enough light to ripen fruit, instead of shading its neighbors.
• Water and nutrients: tomato roots spread widely; crowded plants compete for the same water and food.
• Access: you can reach every plant to tie, prune, check for pests and pick fruit.
• Yield: crowded plants produce less fruit per plant, and diseases spread faster from plant to plant.

How Far Apart to Plant Tomatoes: Spacing Chart by Support Method

How you support your tomatoes has the biggest effect on how far apart to plant tomatoes. Supported plants grow up instead of out, so they can be planted closer together:

The University of Maryland Extension gives a general range of 18 to 36 inches between plants and 48 to 60 inches between rows, and notes that staked, pruned plants can be spaced closer together because they are kept to 1 to 3 main stems.

Tomato Plant Spacing by Type

The growth habit of your variety matters just as much. Check the label for “determinate” (bush) or “indeterminate” (vining):

Determinate tomatoes stop growing at a set height and ripen most of their fruit within a few weeks. Indeterminate tomatoes keep growing and fruiting until frost, so they need more room and taller support. Learn more in our guide on how to grow tomatoes in pots, which compares both types.

Tomato Row Spacing

Tomato row spacing depends on how much room you need to walk, work and let air move between the rows:

• Staked or trellised rows: 3 to 4 feet between rows.
• Caged rows: 4 to 5 feet between rows, because cages take up more width.
• Sprawling tomatoes: 4 to 6 feet between rows, as the plants spread out over the ground.
• Double rows: plant two rows 18 to 24 inches apart, then leave a wide 4-foot path to the next double row.

Leave enough tomato row spacing for a wheelbarrow or a kneeling pad. You will spend a lot of time between the rows tying and picking; our kneeling pad guide helps protect your knees.

Tomato Spacing in Raised Beds

Tomato spacing in raised beds can be a little closer than in open ground, because the soil is loose and rich and you do not walk between the plants. Still, keep at least 18 to 24 inches between staked plants. Here is how many plants fit in common bed sizes:

For tomato spacing in raised beds, plant tall indeterminate tomatoes on the north side of the bed, so they do not shade lower crops. Leave room at the edges for basil or other small companions.

Square-foot gardening sometimes plants one staked tomato per square foot. That only works with strict pruning to a single stem and very rich soil. For most gardeners, 2 feet between plants gives healthier results.

Cherry Tomato Spacing

Cherry tomato spacing surprises many gardeners, because the small fruit comes on some of the largest plants. Most cherry tomatoes are indeterminate and very vigorous:

• Indeterminate cherry tomatoes: 24 to 36 inches apart, or 18 to 24 inches if staked and pruned.
• Compact or determinate cherry varieties: 18 to 24 inches apart.
• Trailing cherry tomatoes for baskets: one plant per hanging basket or window box.
• Micro cherry tomatoes: 12 inches apart, or one per small pot.

If your cherry tomatoes grow into a dense jungle, cherry tomato spacing was probably too tight. Remove some lower leaves and suckers to let air through.

Tomato Spacing in Containers

In pots, the rule is simple: one tomato plant per container. Crowding two plants into one pot means they compete for water and nutrients, and both produce less.

Place pots at least 18 to 24 inches apart, so the plants do not grow into each other. For more tips, see our guide to growing vegetables in pots.

What Happens If You Plant Tomatoes Too Close or Too Far Apart?

Already planted too close? Prune tomatoes to one or two main stems, remove lower leaves up to about 12 inches from the ground and water at the base to keep leaves dry. Disease on crowded plants often starts on the lowest leaves.

Spacing Tomatoes with Companion Plants

Wide spacing leaves room for useful companions. Low-growing basil, parsley or lettuce can grow between tomato plants without competing much, and flowers such as marigolds and calendula attract helpful insects.

• Plant basil 10 to 12 inches from the tomato stem.
• Keep tall companions such as corn at least 3 feet away, so they do not shade tomatoes.
• Give potatoes and eggplant their own bed; they share diseases with tomatoes.

See our full guide on what grows well with tomatoes for a complete companion chart.

How Deep to Plant Tomatoes

Tomatoes are one of the few vegetables you can plant deeper than they grew in the pot. The buried stem grows extra roots, which makes the plant stronger and better able to find water.

• The University of Maryland Extension advises setting transplants so that only two or three sets of true leaves remain above the soil.
• Remove the leaves on the part of the stem you bury.
• Plant leggy transplants in a shallow trench, laying the stem sideways; the tip will turn upward within a few days.
• Mark the direction of a sideways stem, so you do not damage it when you add a stake.

How to Plant Tomatoes with the Right Spacing

A sturdy trowel and a good pair of gloves make planting easier; see our gardening tool sets and gardening gloves guides.

Supports and Spacing

Texas A&M AgriLife compared caged and trellised tomatoes and describes both as practical systems; the choice mainly depends on the space and time you have for tying and pruning.

Spacing and Watering

Good spacing also makes watering easier. Well-spaced tomatoes can be watered at the base without wetting the leaves, and a soaker hose or drip line along a row reaches each plant evenly. Crowded plants often end up with wet leaves and uneven watering.

Read our guide on how often to water tomatoes for a watering schedule by growth stage, and choose a garden hose nozzle with a gentle shower setting for watering at the base.

5 Easy Tomato Spacing Rules to Remember

Common Tomato Spacing Mistakes

• Planting at transplant size instead of at full-grown size.
• Ignoring early signs of leaf disease on crowded plants; see our guide to garden insects and plant problems.
• Using small store-bought cages for large indeterminate tomatoes.
• Leaving too little tomato row spacing to walk and work.
• Planting two tomatoes in one pot.
• Planting tomatoes where tomatoes, potatoes, peppers or eggplant grew last year; rotate beds to reduce disease.
• Letting weeds fill the gaps; see how to keep weeds out of the vegetable garden.
