Capsicum annuum
Developed in the Hatch Valley of New Mexico and once listed as the world's largest pepper in the Guinness Book of World Records, Big Jim produces amazing yields of bright red peppers reaching 12 inches in length and 3 inches wide. No need to worry about how you'll use all of those large peppers, as their mild heat level and excellent flavor make them very versatile. Plants are sturdy but will require support for their heavy yields. Medium heat. Matures approximately 85 days from transplanting. Each packet contains a minimum of 25 seeds.

We’re holding firm to the time-honored traditions and downhome ways that have brought up generations all across these fruited plains. In fact, the varieties offered here are the same ones we place on our own dinner table—and in this way of life, that says something.
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 soil temperature for C. annuum 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. Super hot chiles can take up to a month to germinate. Be sure to keep the soil moist, but not soggy, until germination has occurred. Placing a plastic dome over the trays will eliminate a need for frequent watering during the germination period.
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 an 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. Alternatively, they can be dried by hanging them or placing them on a screen or basket in a warm, well-ventilated location until completely dry.
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.
Note: We have noticed that pepper juice can leach through gloves. It is wise to double up if you are processing a large number of peppers or superhot chiles.
SEED LONGETIVITY:
Pepper seeds will remain viable for three years when stored under ideal conditions.
I still give Thresh a 5 star review. Quick service etc. The fault here was with the customer (yeah that would be me) I mistakenly assumed all I had to be sure of was that all danger of frost was past. Nope - these seeds need soil that is @ 90 degrees F. They like HOT weather - not warm and pleasant weather. Anyway once I compsensated for that (starting the seeds under a grow light with a heater underneath the little germination pots) all was fine. Before that I think that only one seed managed to germinate.
No worries—Hatch peppers are known for being a bit tricky to germinate. We have a full article on how to successfully germinate peppers, including these challenging types. I'll link it below. At any rate, we're glad that you were able to have success with your Big Jim pepper seeds. Wishing you continued luck (and someday soon—enchiladas topped in green chile sauce!)

I started 18 seeds but only 10 popped
So far I have had 2 plants germinate out of 20+ seeds. Very disappointed. The only saving grace is the two plants that did germinate. I will harvest their seeds for next planting.
Hi Brian, thanks for your review. Germinating Hatch-style chiles can be tricky, especially in an aerogarden as the seeds do not like to be wet or cold. You can, however, improve germination rates by placing a seedling heat mat under the aerogarden. The ideal temperature is 80-90 degrees. Our stock just finished its test at 86% germ so we have some good seeds here if you want to try again. I'll be in touch about a replacement packet.
Just about 100% germination. Slow growing like all peppers, but as the summer starts to heat up, I expect they will take off! (Zone 6)
Germinated half in moist paper towel and 4 days later all sprouted. 1 week later they’re now 3” and almost ready for transplanting.
