Latin Name: Capsicum annuum
Hardiness Zone: 4, 5, 6, 7, 8, 9, 10, 11 Technically a tender perennial, but commonly grown as an annual. Perennial in zones 10 and 11.
Days to Maturity: 73 (from transplant)
Days to Germination: 7-10
Seeding Depth: 0.25 inch
Direct Sow: No
Start Indoors: Yes. Start Indoors 6-8 weeks before your last spring frost date. Harden off and transplant when seedlings are 6-8 inches tall. Bury the stem slightly deeper than the root ball. Avoid planting hot and sweet peppers right next to each other, as they can cross-pollinate, potentially affecting the flavors of your harvested peppers.
Pepper Pollination: Peppers have perfect flowers (male and female parts) and will self-pollinate. However, wind and pollinator activity may increase success rates of fertilization and fruit production.
Pepper Type: Sweet - These peppers (think Bell Peppers) are almost all at 0 on the Scoville Scale, meaning that they have no heat at all. A handful of sweet peppers do register very low on the Scoville scale but are still classed as sweet peppers. For example, Pepperoncinis are sweet peppers but usually rank around 100 to 500 on the Scoville Scale.
Plant Spacing: 12-24 inches
Row Spacing: 24-36 inches
Plant Height: 18-24 inches
Plant Width: 18-24 inches
Growth Habit: Upright
Deer Resistant: No
Scoville Heat Units: 0
Heat Level: Sweet - Peppers with no heat. 0-99 on the Scoville Scale.
Growth Speed: Early - Ready for harvest around 61 to 75 days from transplant.
Soil Preference: Well-draining, loose (sandy loam), slightly acidic (6.5 pH), and moisture retaining. Too much nitrogen in the soil may lead to more foliage production and less fruiting, similar to tomatoes. Peppers also need sufficient amounts of phosphorus and calcium. We recommend using a balanced fertilizer for the best results.
Temperature Preference: Warmer (70-85 F). During high heat, foliar and flower development slow or pause until temperatures return to the preferred range.
Germination Temperature: 80-90 F
Light Preference: Full Sun
Pests and Diseases: Peppers are commonly susceptible to cutworms, aphids, flea beetles, bacterial spot, Phytophthora, sunscald, and blossom end rot. To avoid or reduce problems with pests and diseases, stick to a regular watering schedule (drip irrigation is preferred), plant into well-draining soils, and utilize practices such as crop rotation. When taking pest control measures, consider utilizing integrated pest management principles by using mechanical removal, biological control, and other cultural practices before turning to chemical agents.

Growing Marconi Red Organic Peppers in the Vegetable Garden

To grow Marconi Red Sweet Peppers, begin by sowing seeds indoors about eight weeks before the last frost date. Sow seeds at a depth of about a quarter-inch in a well-draining, organic seed starting mix. Ensure the soil temperature is around 70-85 F for optimal germination. Once seedlings have developed a few true leaves and nighttime temperatures consistently stay above 55 F, it’s time to transplant them outdoors. Harden off plants gradually to acclimate them to outdoor conditions over a week. Plant them in a sunny spot in the garden, spacing them about 18-24 inches apart to allow adequate air circulation and growth.

Choose a sunny spot in the garden with well-draining soil to transplant your seedlings, spacing them about 18-24 inches apart to give each plant ample room to flourish. Marconi peppers thrive with consistent moisture and benefit from a layer of organic, untreated mulch to help retain soil moisture and suppress weeds. Support the plants with stakes or cages as they grow, as the peppers can become quite heavy and may cause the branches to bend or break.

Proper watering practices can be one of the most challenging things about having a garden. However, it is crucial, especially once the plants start flowering and fruiting. Aim to keep the soil evenly moist but not soggy. Drip irrigation or soaker hoses are ideal for keeping water off the leaves and providing a steady supply of moisture directly to the roots.

Companion planting can be very beneficial for Marconi Red Sweet Peppers. Good companions include onions, spinach, and basil, which can help repel pests and enhance growth. However, avoid planting them near fennel or kohlrabi, which can interfere with their growth.

Pruning the plants is not always necessary but can help increase yields and air circulation. Removing some of the lower leaves can also help prevent soil-borne diseases and focus the plant's energy on producing fruits.

Peppers are warm-season crops and do best when temperatures range between 65 F and 80 F. They can be sensitive to both extreme heat and cold. Cover the plants with a frost cloth if temperatures are forecasted to dip. Similarly, during heat waves, shade cloth can help protect the plants from scorching.

To maintain these plants' organic integrity, avoid pesticide, herbicide, or fungicide use. Select untreated materials that will not expose the plants to unnatural chemicals. Choose only organic fertilizers such as homemade compost, compost tea, or worm castings.

Harvesting Organic Marconi Red Peppers

Harvesting Marconi Red Sweet Peppers begins when the peppers reach their mature size, and the skin has a deep, glossy red color; this typically occurs around 70 to 90 days after transplanting. Peppers can take a while to mature and change color. It’s important not to harvest too early. Let them fully ripen to red to enjoy their best flavor and sweetness. To harvest, use a sharp knife or scissors to cut the pepper from the plant, being careful not to damage the branches. Regular harvesting encourages the plant to produce more fruit.

This variety, like most sweet peppers, is not hot (0 Scoville Heat Units), which means they're harvested for their mature, sweet flavor rather than heat.

Originally bred in Italy, these peppers are prized for their sweet, rich flavor and substantial size, making them excellent for stuffing, grilling, or fresh eating. These seeds were harvested from organically grown peppers.

These peppers are particularly noted for their excellent performance in containers, making them a superb choice for those with limited garden space.

Tips From Our Gardeners

"If you use a humidity dome when sprouting pepper seeds indoors, be sure to quickly remove it as soon as you see the seedlings poking out of the soil. Waiting even one day too long can cause crop failure due to legginess. I learned this the hard way!"
