The blooms will return: Cool-season bedding plants may bloom less during the midwinter period (especially if the weather is cold), but should pick-up again in the late winter and early spring. Don’t forget to keep the old, spent flowers picked off to encourage continued blooming. If the foliage color is a good deep green, and the plants seem to be growing well, you shouldn’t need to fertilize now. Pansies are, however, heavy feeders. If the foliage is even slightly pale, and if the growth seems slow, fertilize regularly with a soluble fertilizer according to label directions.
