Pansies Slow to Bloom? Root Size and Fertilization Matter

Small root systems from late planting (after mid-October) or insufficient fertilization cause poor winter blooms. Cold, wet weather inhibits root growth. Fertilize now with liquid houseplant food every 2–3 weeks; they’ll bloom by March. Next year: plant 3″ pot pansies in early October in rich, tilled soil, spaced 8–10″, and fertilize biweekly for winter color.
