The University of North Carolina at Wilmington Pansy Care Pansies are much tougher than their name implies. They not only survive cold winter weather, but also put forth a very impressive floral display during a time when few other plants are in bloom. In spite of their toughness, they do need a little help to look their best. UNCW uses the following practices to maintain the beauty and vigor of its pansies.
Pansies expend a great deal of energy during their short life cycle.
Their rapid growth fosters the need for regular fertilization. We apply a granular fertilizer every six weeks. We have found that during the winter, slow release fertilizer breaks down too slowly. On occasion, we use a water soluble fertilizer to supplement our granular applications. To prevent a pansy from expending energy on the production of seeds, wilted flowers should be removed.
