Start red pepper seeds in peat pots using a seed starter mix about 8 weeks before you plan to move seedlings to the garden. Plant the seeds about a quarter inch deep.
Place the peat pots in a sunny location indoors.
Protect the emerging red pepper plants from the cold. The University of Minnesota suggests that you place your peat pots on top of the refrigerator, where it's warm, until the seeds germinate.
Water the seedlings daily, but don't let them get soggy.
Harden off your pepper plants by leaving them outdoors for several days before transplanting them to expose them to the outdoor weather. Do this only after all threats of frost are gone.
Plant seedlings, whether started at home or bought at the garden center, in well-drained soil that's rich with organic matter.
Space your red pepper plants a foot or two apart, tamping the soil around them firmly.
Fertilize with a 5-10-10 product at planting time and again when the plants begin to blossom. Consult the package directions for instructions regarding the brand you choose.
Water frequently enough to keep the soil moist but not enough to be soggy.
Harvest hot red peppers when they've become full and are a bright red. Harvest sweet red bell peppers after they've changed from green to red.
