How to plant Dahlia ‘Northwest Cosmos’
Dahlia ‘Northwest Cosmos’, like all dahlias, appreciates fertile soil with good drainage. They like to be planted in full sun and fed regularly to produce abundant flowers.
Stake and support the stems of the taller varieties or varieties with large, heavy flowers.
Dahlias do not like strong winds or that the soil remains moist and cold.
The tubers must be lifted off the ground or protected with mulch if temperatures in the area remain below zero for many days in winter.
If you pick the flowers regularly or deadhead flowers that start to wither, the plants will respond by producing more flowers.
