Since
there are already plants in the garden, you might want to simply
observe the garden the first year. That way, you can begin to identify
plants and observe their size and bloom time. As you become familiar
with the existing plants and the growing conditions in your yard,
you can decide if you want to add new plants or keep the gardens
as they are. An experienced gardener, whether a neighbor or a professional
from a local garden center, is a good source to help you identify
plants and figure out how to care for them. Other good sources of
information are public gardens, nurseries, perennials catalogs and
Web sites, and garden centers. If you can contact the previous owners,
they may be happy to help you get to know the gardens.
