April in Chester County is not a month for standing still. The garden doesn’t wait for a convenient moment, it pushes forward whether you’re ready or not, and the windows for the most important spring tasks are shorter than most people realize.
Right now, ornamental grasses that weren’t cut back in late winter are the priority. Once the new growth starts pushing through the base, you’re working around it. A clean cut to about four inches before that happens makes all the difference, not just aesthetically, but for the health of the crown going into summer.
Perennials are another April conversation. If your Hosta clumps have been in the same spot for three or four years and they’re starting to look crowded or bloom less reliably, this is your window to divide them. The same goes for Rudbeckia, Echinacea, and most of the ornamental grasses. Division in spring, when the new growth is just a few inches tall, gives the transplants an entire growing season to establish before winter. Wait until fall and you’re gambling.
For anyone with a formal border or a property that relies on consistent structure, this is also the time to assess what didn’t come back. Not everything that looks dead in April is dead. Hibiscus moscheutos is famously slow to show itself, sometimes waiting until late May. But gaps in the border are easier to address now, before neighboring plants fill in and make planting awkward.
One thing I watch closely in April is the late frost calendar. Chester County can surprise you into the first week of May, and tender annuals planted too eagerly in warm weather get caught. The forsythia blooming is a useful marker. When forsythia finishes, you’re usually safe to start hardening off transplants. Not always. But usually.
The garden is moving fast right now. Get out into it.
