Sweet Pepper Planting Information:

Sweet peppers can be grown anywhere with 4 months without frost. You can also grow sweet peppers in containers. Sweet Pepper seeds are sensitive to temperature and moisture. Do not soak the seeds in any solution or water before planting, as this may damage them, cause them to rot, and prevent germination. Plant your seeds indoors between January and March, or 5 to 7 weeks before setting them outside in the garden. Use Miracle-Gro Seed Starting Material for the best germination results. When plants are 12" or taller, transplant them outdoors. Only plant peppers outdoors on a cloudy day, just before getting rain. Plant when the soil is warm, at least 2 weeks after the last frost, and when temperatures remain above 70 F. Plants can grow 3 to 4 ft tall.

Soil Requirements:

Requires fertile soil in a well-drained garden location. Apply mulch, grass clippings, or straw around the plant's base.

Water Requirements:

Water thoroughly with soaker hoses during dry, hot spells.

Fertilizer Requirements:

Use slow-release (6-month) Fertilizer when transplanting outdoors. Apply Miracle-Gro Liquid Fertilizer every two weeks.

Harvest Tips:

Harvest sweet peppers when fully mature using garden scissors so you don't damage the plant. Pick peppers as they mature to encourage new flowers to form.

Note: The temperature, moisture, and air circulation all play a role in growing plants from seeds. Too little heat, too much moisture, and lack of air circulation will cause poor germination results. Warning: Do not use peat pots, plugs, or potting soil for growing sweet peppers from seeds as the soil may become too dry or too wet, which can lead to disease, fungus, and poor germination results. Do not use covers or lids as lack of air and condensation moisture will cause poor germination results, disease, and fungus. Use Miracle-Gro© Seed Starting Mix for best germination results.
