Pepper plant spacing: how far apart to plant peppers
Sep 27, 2026 · 5 min read
Space pepper plants 12 to 24 inches apart in rows 30 to 36 inches apart, or in paired rows 15 inches apart on a raised bed. What university extensions recommend, and when to go wider.
Plant peppers 18 inches (46 cm) apart in rows 30 to 36 inches (76 to 91 cm) apart. That is the University of Minnesota Extension figure, and it sits in the middle of what other extension services give: 12 to 24 inches between plants at the University of Maryland, 12 inches at Clemson. On a raised bed, Utah State University puts two rows 15 inches apart on a 30-inch bed, with plants 12 to 18 inches apart in each row. In a container, one plant to a pot of at least 5 gallons.
Most pepper varieties in our catalog grow 18 to 36 inches tall, and those numbers fit them. The rest of this guide covers why the range is as wide as it is and which end to pick.
Spacing in rows
| Source | Between plants | Between rows |
|---|---|---|
| University of Minnesota Extension | 18 in (46 cm) | 30 to 36 in (76 to 91 cm) |
| University of Maryland Extension | 12 to 24 in (30 to 61 cm) | 30 to 36 in (76 to 91 cm) |
| Clemson Cooperative Extension | 12 in (30 cm) | 3 ft (91 cm) |
| Clemson, pimento peppers | 18 to 24 in (46 to 61 cm) | 42 in (107 cm) |
Clemson spaces ordinary peppers a foot apart but gives pimento peppers nearly twice that, with wider rows. Spacing follows the size of the plant.
Raised beds and paired rows
Utah State University’s bed layout packs peppers closer than the row figures above: two rows 15 inches apart on a bed 30 inches wide, plants 12 to 18 inches apart within each row, and beds 36 to 42 inches from center to center. The University of Maryland describes the same thing for home gardens as double, staggered rows in a bed 2 feet wide.
In a staggered layout the plants in the second row sit opposite the gaps in the first, so each plant keeps its distance from its neighbors while the bed holds more of them.
Utah State gives one reason beyond saving space: paired rows help reduce sunscald.
How close is too close
Spacing has a sunscald side too. The University of Minnesota says sunscald occurs on fruit that develop on small plants, where the developing peppers are exposed to intense direct sun and form flat, tan areas, and Utah State notes that paired rows help reduce it. Minnesota also advises growing peppers closer together where temperatures stay below 60°F, and notes that closer spacing needs fertilizer at planting and through the summer.
None of the sources goes below 12 inches between plants in the row.
Which end of the range to use
The extension figures are written for the typical pepper plant. The plant sizes in our catalog give a way to place a variety within them. This part is our reading of the ranges, not an extension rule:
- Compact varieties that stay under about 2 feet, such as Carmen or TAM Jalapeño, can go at 12 inches, or in the staggered bed layout.
- Most bells and medium hot peppers, 2 to 3 feet tall, such as California Wonder or Shishito, fit the middle figure of 18 inches.
- Large plants want 24 inches. The Vegetable Cultivar Descriptions compendium records Tabasco plants reaching 1,000 mm (about 3 feet), and Pepper Joe’s says Manzano, a rocoto, can grow ten to fifteen feet if it is protected from frost.
Plant heights for every variety are on its page in the pepper catalog.
Peppers in containers
The University of Maryland sets 5 gallons as the minimum container for a pepper. Each variety page in our catalog gives a minimum container size where the variety suits pots at all.
Support
Maryland also notes that pepper stems can become brittle and should be supported with cages or short trellises.
The short version
18 inches between plants and 30 to 36 inches between rows for most peppers. 12 inches for compact plants, 24 for large ones. On a raised bed, two staggered rows 15 inches apart. In pots, one plant per 5 gallons or more.
The planting guide covers when to set peppers out, and pepper companion plants covers what can go in the space between them.
