Overview

Lantana is a heat and sun-loving plant that blooms profusely from spring to frost. Some cultivars grow up to 6-feet tall while others stay low to the ground but spread 4-feet wide. Lantana is hardy in USDA zones 8 to 11, which means that they survive best where the temperature does not drop below 10 Fahrenheit. In some areas this plant can survive as a perennial, but in most it grows as an annual flower.

Step 1

Plant your lantana in an area with full sun and well-drained, slightly acidic soil with a pH below 6.5. Lantanas like warm soil, so planting two weeks after the last frost will help the flowers start properly.

Step 2

Water your lantana, keeping the soil moist for the first couple of weeks after planting. When the flowers start growing more vigorously, they can withstand drought. For best flower production, however, they require about 1 inch of water a week. Do not water from overhead, as this will increase the chances of root rot.

Step 3

Fertilize with a general, all-purpose garden fertilizer in spring. Lantana flowers do not need much fertilizer and too much will inhibit flowering. Fertilize again in mid-summer, if necessary.

Step 4

Pinch back the tips of your lantana plant in the summer to encourage blooming. For plants outgrowing their allotted space, you may cut them back to one-third their original size without damage. Water and lightly fertilize pruned lantana flowers and they will flower again soon. Prune perennial lantanas back to 6 to 12 inches in height in the spring.

Step 5

Put a 2- to 4-inch layer of mulch around your perennial lantana after the first frost. This will protect the roots from cold damage and keep your plant healthy until its return in early spring.
