Plant pageant primroses in indirect light, in bright shade, but not in full sunlight. They can take sunlight in the cooler parts of the day but should be shaded during the hottest part of the day. Indoors, put your pots of primroses in indirect sunlight near a cool window.
Plant pageant primroses in cool areas. Primroses prefer temperatures in the range of 55 degrees to 65 degrees Fahrenheit. They don't do well in hot climates. Inside the house, keep your potted primroses in a cool area, near a window.
Water pageant primroses when the surface of the soil feels dry. Keep them moderately moist, but not wet. Use plenty of humus in the soil to provide good drainage. Primroses prefer slightly acidic soil with plenty of compost. They don't do as well in sandy or clay soil.
Propagate pageant primroses by dividing the roots and replanting them in new areas. You can also propagate them by root cuttings, or by scattering seeds directly on the soil. The seeds need bright light to germinate, so don't bury them in soil. The same is true if you start seeds early in the year inside -- spread the seeds on the planting medium and keep them damp, in bright light.
