- Gold lantana plants are tolerant of drought conditions and heat. However, if the plant is left in the extreme heat without water, the plant will not bloom as brightly if at all during the growing season. Keep plants healthy and blooming by giving the plant at least 1 inch of water per week in drought conditions. This is especially true when temperatures soar into the 80- and 90-degree-Fahrenheit range.
- Lantanas need full sunlight to flower profusely. Plants located in shady areas will bloom, but not as much as a gold lantana planted in an area with at least six hours of sunlight daily. Morning sun with some afternoon shade is best for the gold lantana.
- Lack of blooming or growth can be attributed to the winter weather. Lantanas are grown as perennials in warmer climates in U.S. Department of Agriculture plant hardiness zones 8 to 11, but as annuals in colder areas with harsh winters such as USDA zones 1 through 7. Although the green foliage may appear after a harsh winter, the plant may not bloom because of severe winter damage.
- Gold lantana plants have few problems with pests, but one pest in particular can cause the plant not to bloom or bloom very little. The lantana lace bug is a close relative to the lace bug that attacks other plants such as sycamores and azaleas. Bugs will feed on the new growth and flowers. Lantana lace bugs draw out the juices in the plant, leaving the plant with fewer blooms or no blooms. Insecticidal soap or insecticidal sprays will kill the lace bug and help you salvage the gold lantana for the next growing season.
