Growing Giant Marconi Hybrid Peppers in the Vegetable Garden
To grow your peppers, prepare your seed starting trays and plant the seeds. Start the process about 6-8 weeks before your last spring frost date. Plant the seeds in either a well-draining soil or in a seed starting mix like Minute Soil Coco Clair. The pH of the soil should be about 6.5. The seeds should be planted about 0.25 inches deep. Make sure the soil stays moist, but don’t overwater your seeds. You can stick your pinky into the soil to see if it is dry below the surface. If it is, then give your plants a little water, but make sure you don’t overwater them. Keep the peppers in a warm area, between 80-90 F, so they can germinate. A grow light is a great way to keep their growing area warm. Once the seedlings emerge, normally after 7-10 days, you can start the process of hardening off your plants! Once the plants are about 6-8 inches tall, you can move them to a cooler area, around 70 F, to prepare them for being outside! Choose a nice sunny location in your garden or in pots for your plants. Plant the rows about 2-3 feet apart, and plant individual plants about 12-18 inches apart. Dig a hole and make sure the roots are covered completely!
There are several things you can do to make sure your peppers grow well. Make sure that you water your plants consistently, especially during dry periods. Sprinkle some mulch around the base of your plants to keep the soil moist and prevent any pesky weeds. To help your plants grow, you can try giving them fertilizer full of phosphorus and calcium. Be sure to follow the instructions on your fertilizer and not over-fertilize them. If your pepper plants get tall, you may need to provide them with stakes or a cage to support the weight of the fruit. You can also try companion planting - plant some marigolds and basil alongside your peppers to attract pollinators and keep the pests at bay. And keep an eye on your peppers - if you spot any pests or diseases, make sure to treat them immediately!
Harvesting Giant Marconi Hybrid Peppers
As your peppers fruit, keep a close eye on them so you are ready to harvest fruit as soon as it is ripe. The fruits will typically be ready within about 72 days of transplanting, and they will be a bright cherry red color or a bright green and have a firm feel. Because this is a sweet variety, these peppers taste better when they are fully ripe, when they’re about 6 to 8 inches long and have a glossy sheen. To harvest Giant Marconi Hybrid peppers, use garden shears or a knife and cut the peppers from the plant. Make sure to be gentle and aim for a clean cut, and leave a small stem on the plant.
About Giant Marconi Hybrid Pepper Garden Seeds
This pepper is an Italian-type sweet pepper, but this hybrid version was developed in the United States.
This pepper was an AAS winner in 2001 for its yield, pepper size, earliness, and flavor. It is resistant to Potato Virus Y and Tobacco Mosaic Virus. These peppers grow 6-8 inches long and have a sweet, smoky flavor.
Because they can grow 2-3 feet tall, these peppers aren’t a good fit for hanging baskets or smaller pots, but they grow well in plots, raised beds, and greenhouses.
Tips From Our Gardeners
"Make sure you don’t plant these sweet peppers too close to hot peppers - they can cross-pollinate. These peppers are great for frying!"

Basic Info
| Latin Name: | Capsicum annuum |
| 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. |
| Giant Marconi Hybrid Pepper Color: | Red, Green |
| Giant Marconi Hybrid Pepper Flavor: | Mild, sweet, and smoky |
Growing Info
| 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: | 72 (from transplant) |
| Days to Germination: | 7-10 |

| Plant Spacing: | 12-18 inches |
| Row Spacing: | 24-36 inches |
| Plant Height: | 24-30 inches |
| Growth Habit: | Upright |
| 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. |
| Light Preference: | Full Sun |
Other
| 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. |
| Plant Width: | 18-24 inches |
| Deer Resistant: | No |
| Scoville Heat Units: | 0 |
| Heat Level: | Sweet - Peppers with no heat. 0-99 on the Scoville Scale. Example: Bell Peppers |

| Pests and Diseases: | Resistant to Potato Virus Y and Tobacco Mosaic Virus. 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. |
