Dig a hole the same depth and double the width of the lantana's root system. Place the roots into the planting hole at the level they were growing before. Return the loosened soil and use your palm to firm it around the plant.
Add water until the soil feels lightly moist down to the roots.
Continue to water once each week, unless there has been an abundance of rainfall.
Feed one time in early spring with general purpose fertilizer.
Prune in early spring to keep trailing white lantana from outgrowing available space. You can also remove dead growth at this point or trim the plant all the way back to the ground to encourage abundant new foliage.
