I have 32 large, robust looking pansy plants that I grew from seeds. There aren't any blooms yet, but there is one with a bud on it. Why? At the greenhouse I see the little trays with small plants already in bloom. Other years I bought pansy plants already blooming, and after I set them out in my flower bed, the leaves turned brown, the plants got tall and leggy and died. There is compost in our soil and it seems like a good mix. What am I doing wrong?
