You can be very successful in growing vegetables in Washington County. The most important thing to remember is to “plant at the right time”! Washington County has a dry desert-like climate that is unlike any other place in Utah, with the possible exception of Moab. For cool-season vegetables, the gardening season starts in February. By the first week of April, consider planting tender vegetables like tomatoes. Take a little break during the July and August heat, and then come back in mid-September and plant your Fall garden. The second most important thing to do is amend your soil. Most soils will have a high pH, low organic matter, and be poor in nutrients unless it has had a garden on it or has been farmed in the past. If you do not know your soil’s history then running a soil test is the best way to get started.
