Description

Source: leafsnap

Dahlia merckii, Merck's dahlia, is a species of flowering plant in the daisy family Asteraceae, native to Mexico. This tuberous herbaceous perennial has divided leaves, and produces single flowers in shades of lilac, white and pink, in late summer and autumn.Growing to 2.5 m (8.2 ft), it is hardy only in milder areas which do not suffer prolonged frosts, where tubers may be left in the ground throughout the year, and protected with a mulch in the dormant season. Otherwise tubers must be lifted and stored over winter. They begin to sprout in spring, but must be protected until all danger of frost has passed. Propagation is by seed or cuttings in spring.

🌱 Fertilizer

The best time to fertilize a Species dahlia is in early spring, when it is coming out of dormancy and starting active growth. Fertilizing supplies essential nutrients for healthy development. Although Species dahlia has fairly low fertilizer requirements, an annual application can boost its survival and encourage better, longer-lasting blooms.

🪴 Pot & Repot 2-3 years
