Days to Maturity: Approximately 70-80 days from transplant to first harvest (often 75 days typical).
Sun Needs: Full sun with at least 6-8 hours of direct sunlight daily—critical for vibrant purple coloration and fruit production in Utah’s intense summer light.
Season Type: Warm-season crop; frost-sensitive—transplant only after soil warms to 65°F+ and all frost danger has passed (late May to early June in the Salt Lake City area).
Plant Habit & Support: Compact, bushy plants grow 18-30 inches tall and wide; light staking may help with heavy fruit loads—space 18-24 inches apart for airflow.
Other Notes: Highly ornamental with striking purple foliage and striped fruits; monitor for aphids, spider mites, or blossom-end rot—consistent moisture and organic mulch (like straw or compost) help prevent problems.
Best Planting Method: Transplant when nights stay above 55°F and soil is warm. Space plants 18-24 inches apart in rows or beds; bury stems slightly deeper if leggy to promote strong roots. Amend soil with compost for fertility and excellent drainage—raised beds are highly recommended in heavier or alkaline Utah soils to improve root health and avoid rot. Organic mulch (such as straw, compost, or grass clippings) around plants conserves moisture, suppresses weeds, and moderates soil temperature.
Watering Needs: Keep soil consistently moist but not waterlogged (about 1-1.5 inches per week), with deeper watering during flowering and fruit swell—drip irrigation is ideal in dry Utah air to keep foliage dry and reduce disease risk. Avoid drought stress or irregular watering, which can cause blossom drop or smaller pods; mulch helps maintain even moisture, and containers may need more frequent checks in hot weather.
Fertilization Needs: Incorporate compost or balanced slow-release fertilizer (e.g., 10-10-10) at planting. Side-dress with a higher-phosphorus/potassium formula (like 5-10-10) at transplant and again when flowering/fruit set begins to promote strong fruit over excess foliage. Peppers are moderate feeders—avoid high nitrogen late in the season to prevent lots of leaves but fewer or smaller peppers; organic options like compost tea support steady growth. Harvest when fruits show good striping and color—cut with pruners to avoid damaging plants and encourage more production.
