Marconi Red’s large peppers grow every bit as impressively as the hybrid Giant Marconi (at least in our hands). Unlike its hybrid counterpart, however, this heirloom will produce seeds that breed true each generation, ensuring you’ll enjoy these sweet red long peppers for years to come. Matures approximately 70 to 90 days after transplanting. Each packet contains a minimum of 25 seeds.

We're seed savers first—and that attitude goes into everything we do. That's why we only offer varieties that are capable of producing true-to-type seed. What's more, our resealable, mylar-lined packaging can be reused when you're ready to harvest your own seed crop.
Peppers perform best in well-drained soil that contains plenty of organic matter and adequate phosphorous and calcium. Mulching plants with poly, paper, or natural materials will ensure consistent moisture throughout the root zone.
For earliest harvest, start seeds indoors 6-8 weeks before the last frost. Sow seeds 1/4" deep in well moistened, sterile seed-starting mix. The ideal temperature for pepper seed germination is 85 degrees. For best results, place a grower's heat mat beneath trays until germination has occurred. Under ideal conditions, germination should occur in 10-14 days.
After danger of frost has passed, set transplants 18-24" apart in rows 24-36" apart. Ensure that plants receive 1-2" of water per week. Avoid over-application of nitrogen as this can cause vegetative growth at the expense of fruit set.
Insect Pests
Biological controls such as Bacillus thuringiensis can be effective in controlling climbing cutworms. Aphids, flea beetles, and other hard-shelled insects can be controlled with a simple homemade insecticidal soap solution.
Diseases & Other Problems
To prevent common pepper diseases like Phytopthora and bacterial spot, avoid watering plants at night or on cool, cloudy days. Excess nitrogen and/or insufficient phosphorous can cause pepper plants to become bushy and produce few blossoms.
Peppers can be harvested at any time, but should be picked before they become soft or overly mature. Harvesting regularly will encourage further fruit set. Peppers can be stored in the refrigerator for 4 to 5 days.
CONSIDERATIONS:
Select disease-free plants that are true-to-type. Pepper plants are prone to cross pollination by bees, so precautions should be taken to prevent pollination by insects. Covering plants with mosquito netting is an effective method to protect against pollen contamination.
HARVESTING SEED:
Harvest mature, disease-free fruit that have developed their final color. Cut open fruit and use a gloved hand to remove the seed. Dry on a coffee filter or paper towel. Store in an airtight container until ready to use.
SEED LONGETIVITY:
Pepper seeds will remain viable for three years when stored under ideal conditions.
Out of 24 seeds, I have 21 plants growing! Impressed right now !
I received my Marconi Red Pepper seeds today the seeds looks great . I'm excited to put some in a seed tray to get them started . Ive never had any issues with orders from Thresh. orders arrived quickly I will update you when I can plant them in the ground.
Nice packaging and can't wait to see how they do next spring! We'll see how it goes!
I am so impressed with the extra fast service of this company! I placed this order on a Friday morning from my home in Baldwin County Alabama ( we are 35 minutes from the Gulf). My order went in the mail that afternoon. It was in my mailbox Monday afternoon!! This company is in Stuart, Iowa (a very long way from where we live in Alabama!!)
Still early, but I planted 6 seeds and 6 germinated. Hoping for some big sweet stuffers this fall.
