Ensure that the soil drains well, and add amendments to improve the drainage where necessary.
Lantana plants that have wet roots all of the time will end up experiencing the onset of diseases and pests.
Plant the lantana in flowerbeds or as border plants around the garden. When planting, gently coax the roots out of the transplant pot, and place them in a prepared hole.
Cover the roots with soil, but make sure you don’t cover the crown of the plant. If you cover the crown of the plant with mulch, it results in the onset of disease.
After planting, press down on the soil around the base of the plant to remove any air pockets.
