If I put Preen Garden Weed Preventer in my flower bed in the spring, will it effect the growth of my perennials?

Well you should use it after the growth because it probably will effect the growth.
No. I have use Preen and other pre-emergents for the last 10 years in commercial and residential projects and I have never experienced any problems. To throughly set your mind at easy the please read the label and ensure your perennials are covered as safe for use.
It will only affect germinating seeds. if you have not sown any seeds, and have nothing that you rely on “self-seeding” each year to enjoy, it won’t hurt existing plants.
