Prof. Samuel Fitzgerald, Ph.D.Getting the spacing of your pepper plants right is more important than you think. Proper spacing helps prevent disease and increases the harvest. Different types of peppers require different spacing. Small types, such as jalapeños, do best when planted 18 inches apart. The larger bell pepper needs 24 inches or more. Containers have their own rules.
In my garden, I learned spacing lessons the hard way. The congested peppers had yellow leaves and mildew. Their roots were struggling for food. The air could not circulate between the plants. Now I have a ruler and measure every time I plant seeds. You should, too, and have a better garden.
Make your bed spacing smart. Instead of a straight row pattern, plant in a diamond pattern. This gives every plant an equal amount of light and air. You will have 24-inch paths in between the beds. These access lanes will make it easier for you to water and harvest.
Container peppers require isolation rather than space in the ground. Pots ought to be placed 18 to 24 inches apart. This will avoid roots tangling between pots. Use large pots, five gallons for medium peppers and ten gallons for the large ones, such as habaneros.
Raised Beds
- Use diamond planting patterns
- Maintain 24 inch access paths
- Double rows for beds under 3 feet wide
Containers
- Space pots 18-24 inches apart
- Rotate weekly for even sun exposure
- Elevate pots for drainage
Traditional Gardens
- Rows 24-36 inches apart
- Stagger plants in adjacent rows
- Add trellises for vertical space saving
Measure carefully at planting time. Use a folding yardstick or a string with clearly marked measurements. I am in the habit of making cardboard templates for uniform spreading. Biodegradable spray paint spots places quickly. Double-check on distances twice during the growing season. Make adjustments if plants seem to be crowded.
Proper spacing eliminates most pepper problems. It prevents diseases before they start, and it ends fights for nourishment and water. Your peppers will grow bigger. They will be healthier all season. Take the time to space them correctly.
