I have clients who won't be able to move into their new home for a couple of months after closing during the two hottest months of the summer.  They're worried about the garden and lawn in their new home during the time they won't be there.

A lovely garden is a substantial part of the value of a home, so you don't want to make the mistake of not caring for it properly.  Canadian writer, P. J. Wade, suggests joining a local garden club to help out with advice on keeping the lawn and garden in shape, especially if you're a neophyte at gardening.  Garden club members are glad to offer expert advice about how to maintain a garden design, especially if local conditions present a special challenge as they do here in our high-altitude, dry climate.  The Colorado Federation of Garden Clubs is the place to find local expertise.

 You might also want to consider xeriscaping for a low-maintenance, low-water use garden.  Twenty years ago the Denver Water Department originated the use of xeriscaping for hot, dry climates and the practice is in wide use in the desert southwest.  Xeriscape gardens can offer an alternative to a high-maintenance, Kentucky bluegrass yard, and are quite beautiful. 

If you have specific questions about gardening in the Denver area, ask me.  I've been a Colorado Master Gardener since 1987.
