There are lots of different options when you hire a gardener. Do you want regular garden maintenance? Do you just need a garden tidy once a year? Would you like to get your hedges trimmed and tidied up?
Much of it depends on your individual garden and your preferences. Some people prefer to have a gardener come every week and do absolutely everything, like tidying up leaves and mowing the lawn. Some people like to do some of the gardening themselves so might prefer to have a gardener come less frequently.
The first step is deciding what you need. Think about how much work actually needs doing in your garden and how much you would like to do. You can then contact a gardener and tell them what you need. They will usually offer to come to your property and look around to assess the work and give you a quote.
