Things to remember about desert lantana plants. If you live in an area that gets temperatures below 32degrees F. you will need to trim them down at ground level and cover them with mulch. Be sure to water about once or twice per month during the winter season. It is best to use lantana in containers and bring them indoors if you live in areas that get temperatures in the teens or below. Lantana plants are very hardy once established. Water almost daily when first planted. Once established they require only moderate to low water. Fertilize with a high level of phosphorus only if blooms do not show up during the summer months.
