Sow evening primrose in fall (ideal) or early spring in full sun with well-drained soil. For spring sowing, a short cold period helps—chill seeds in the fridge for 3–4 weeks before planting. Scatter seeds, cover lightly (about 1/8 inch), and press in. Keep soil lightly moist until sprouts appear in 14–28 days, then water deeper but less often. Thin to 12–18 inches apart. Evening primrose is tough once established; avoid overwatering and heavy fertilizer. Let a few seedheads mature if you’d like it to reseed naturally.
