Tine to cut back tall perennials. Late May/Early June is the perfect time to manage the height and manipulate the bloom time of many garden perennials. This is particularly true of some native plants that get tall in the garden and are subject to lodging (toppling over). Joe Pye weed (Eutrochium spp. and cvs., Zones 3–9), ironweed (Vernonia spp. and cvs., Zones 4–10), and goldenrod (Solidago spp. and cvs., Zones 3–9) are all good candidates for getting haircuts before the end of the month.

What will you be cutting back as May transitions to June?
