Care of the plant Dahlia coccinea or Red dahlia

The genus Dahlia, family Asteraceae, comprises 30 species of tuberous plants native to Mexico and Central America. Some species are: Dahlia coccinea, Dahlia imperialis, Dahlia pinnata, Dahlia sambucifolia, Dahlia spectabilis, Dahlia excelsa.

Common names: Red dahlia, Scarlet dahlia. This species is native to Mexico.

They are perennial herbaceous plants with tuberous roots that can exceed 1.5 meters (4.92 feet) in height. The toothed leaves are dark green above and pale green below. The abundant and showy flowers have a yellow center and red, orange, purple, yellow, white or multi-coloured petals. They bloom in summer and fall.

They are used in borders, in borders, in informal gardens and in pots for patios, balconies and terraces. The tuberous roots are edible.

The Dahlia coccinea prefers full sun exposure and a warm climate. It does not resist frost.

The soil can be a normal well-drained garden soil with coarse sand and containing abundant organic matter.

Water regularly so that the substrate never dries out completely; it is important not to flood.

Fertilize with compost in early spring or at the time of planting the tubers.

Prune faded flowers to encourage the appearance of new flowers. In mid-autumn, prune the plants almost from the base and leave the tubers buried; in frosty regions dig up the tubers and replant them in spring.

They are sensitive to attack by fungi and diseases caused by viruses.

They are propagated by division of the tubers in spring.
