Frequently Asked Questions about perennials

Water your perennials well after planting them. Then lay a 2- to 3-inch-deep layer of mulch over the soil around your new plants. The mulch will help the soil hold moisture and prevent weeds from growing.

Deadheading simply refers to removing the faded flowers off the plant. By cutting the spent flower stalks, it encourages the plant to put its energy in producing more flowers rather than producing fruit and seeds.

In most part of the country, with the onset of winter, the perennials will die back. A thick layer of mulch of dead leaves, or bark will help protect the underground structures of the plant.
