Desert marigold is a sun-loving, heat-tolerant genus, preferring full exposure and well-drained soil conditions. Water requirements are moderate; overwatering may cause root decay. The plants thrive best in a temperature range of 70-85°F. Challenges include pests like aphids and spider mites, leaf spot disease, and sensitivity to frost. Seasonally, desert marigold requires less water in winter, more mulching in summer heat, and protection from early frosts. Regular pruning in spring assists blooming.
