As a native maritime herb, you must mimic this tropical climate closely to get the right spice from your ginger. These plants like temperatures of 70-90 degrees and high humidity; give them full sun in cooler areas and partial shade in warmer areas. Use well-draining soil and water enough so it’s consistently moist but not soggy. In the spring, keep watering low until new growth starts. This will reduce rotting.
One reason people love ginger is that it’s very pest-resistant. Predators are almost non-existent in cold areas; in warm regions, the main predators are caterpillars, thrips, scale insects and nematodes. The main concern is diseases which include soft rot, fusarium yellows, leaf spot and bacterial wilt.
