Growing Guide Streptocarpus (Cape Primrose)
LIGHT: The Cape Primrose is a relative of African Violets and prefers the same growing conditions of bright but indirect light. Avoid hot sun, which can burn the leaves and fade the flowers.
TEMPERATURE: Day and night temperatures of 60-75 degrees F are fine year round.
WATERING: Water only when the top inch of the potting mix is dry to the touch. Providing water too frequently will cause the roots, leaves, and base of the plant to rot. If the leaves look wilted even when the soil is moist, you may be overwatering. Let the top inch of the potting mix dry out before watering again. Plants require less water during the winter months (November through February).
FERTILIZER: From spring through fall, apply a water-soluble fertilizer that is high in phosphorus (such as 15-30-15) every 3 weeks. Withhold fertilizer during the winter months, when your plant will stop growing actively and rest.
CONTINUING CARE: Use scissors to cut off the stalks of faded flowers. The tips of older leaves become dry as they age, and these too may be trimmed off. Repot your plant into a slightly larger pot in spring.
