When should you plant trees in the desert?
When to Plant Year-round planting in the desert is possible. The ideal planting time, however, is late fall (except for frost sensitive species) when soil temperatures are warm and air temperatures cooler. This encourages rapid root establishment. Late spring is also good, although root establishment may be slower.
