Carrots need plenty of deep root space, but they're so sweet and juicy when freshly pulled from the ground that they deserve a place in your raised bed. Go light on fertilizer to avoid forked roots. Sow seeds 1 inch apart and thin plants to 3 inches apart after they are up and growing.
Just about any herb you plant now will thrive with little care, except basil, which will appreciate it if you wait until the soil is warm to plant. Plant container-grown perennial herbs such as lavender, rosemary, sage, thyme, and mints and sow seeds of dill, fennel, and parsley.
Zonal geraniums are the perfect flowers for large containers and window boxes. They grow best in a gritty potting soil that drains well. Feed plants regularly with a balanced liquid fertilizer and enjoy exuberant umbels of color from now until fall.
Chrysanthemums that survived winter should be showing tufts of leaves. It's the perfect time to dig and divide them. If you don't want to give up space for them in your flowerbeds, move them to a sunny spot in the vegetable garden where they can grow freely until they bloom in the fall.
Many dianthus that are sold as annual bedding plants will stick around for two or three seasons as a short-lived perennial in our climate. They look great grown with other annuals. Pair deep pinks with soft gray dusty miller, or give red dianthus a companion that blooms white, such as sweet alyssum.
