After skyrocketing in spring, many summer perennials will now be beginning their summer show.
Don’t forget to deadhead. Not only will this lengthen the display, but you can also control the flowering time of some plants. For example, if you’re going on vacation or leaving home for a few days, do all your deadheading right before you go, and you’ll come home to fresh blooms.
