In order to encourage our annuals and blooming perennials to provide us with an abundant show through May, it is a good idea to do some selective pruning in Mid-February and March. You are free to prune back alyssum and lobelia but be warned that if we get a freeze before they fill back out they might not make it. When you cut back you want to make sure you leave some green to promote growth. I prefer to weave my hand (sort of like a chunky hair weave) through the top 1/3 of the plant and cut back all the under growth. This leaves plenty of plant to initiate new growth and allow for protection.
