How to care and grow Taro (Colocasia esculenta ‘Black Coral’):
Most of these plants prefer rich, moist soil and can be grown in full sun, but they generally prefer partial shade.
It grows in well-drained and fertile soil, which is rich in organic matter. Soil should be slightly acidic to neutral with a pH level between 5.5 to 6.5. Avoid compacted and clay-rich soil.
It grows well when the temperature is 25-35°C.
Taro is a high water plant. The more water they get the greater they’ll grow. A few assortments will even thrive when planted in a pot and grown as a marginal pond plant. Containers will need to be watered daily during the summer. Plan on giving plants at least 2-3 inches of water per week.
Fertilize monthly with a general fertilizer of choice. Organic slow-release fertilizers will last longer, so choose something like bonemeal or bloodmeal when possible.
Propagation of taro is usually done by planting corms, suckers, or by division.
Pests and diseases
Aphids, red spider mites, taro beetle, taro leaf blight, and downy mildew may attack taro.
