Answer: Winter is generally a slow time in the garden. The grass may grow when the temperature is above 40F but most everything else will be resting so there's not much to do. If rainfall is sparse you'll want to water everything about every 7-10 days. If you hire a gardener, escort him around the property and ask him how he intends to take care of the plants. He should mention weeding, mowing, and pruning fruit trees. As a rule the gardener will know what to do and when. He/she should also recommend fertilizing both lawn and shrubs in March or April.
There are lots of books you can check out from the library so you can learn more about the specific plants you have in your yard.
Best wishes with your landscape!
