Partially cut back Lavendula (Lavenders), Iberis (Candytuft), Bergenia cordifolia, and Helleborus (Lenten Rose)

Apply pre-emergent weed control according to directions. Water-in by hand if no rain is in the forecast.

Be patient with late-emerging perennials such as Ceratostigma plumbaginoides (Plumbago) and Platycodon grandiflorus (Balloon Flower)
