Growing lantana in the garden is a great way to add color and interest. Simply choose a sunny location and plant them in well-draining soil. Although these plants are tolerant of many soil conditions, lantana flowers prefer slightly acidic soil. Mulching is an easy way to raise pH levels in areas with low acid. Keep in mind, however, that they prefer warm temperatures so new growth may be slow to appear. Once the temperatures warm up though, they will grow abundantly. Caring for Lantana Plants While newly planted lantanas require frequent watering, once established, these plants require little maintenance and are even tolerant of somewhat dry conditions. In fact, a good soaking about once a week should keep them relatively happy. Although it isn’t required, lantana plants can be given a light dose of fertilizer each spring, but too much may inhibit their overall flowering. To encourage reblooming, cut the tips (deadhead) periodically. Overgrown plants can be given new life by cutting back a third of their growth. They will bounce back quickly. Regular pruning of the plant usually takes place in spring.
