Dahlias are typically planted in the spring after the danger of frost has passed and the soil has warmed up. 

Dahlias flourish in abundant sunlight and necessitate a minimum of 6-8 hours of direct sun exposure on a daily basis for optimal development and blossoming.

Dahlias favor soil with excellent drainage and an abundance of organic matter. Optimal growth can be achieved with a sandy loam or loamy soil.

Dahlias require regular watering, especially during hot and dry periods. Aim to keep the soil evenly moist but not waterlogged.

• Yes, dahlias benefit from regular fertilization. Use a balanced fertilizer with a higher phosphorus content to promote blooming.

Tall dahlia varieties may require staking or support to prevent them from toppling over. Use stakes or cages to provide support as they grow.

To encourage continuous blooming, remove spent flowers by cutting the stem just above a set of healthy leaves or lateral bud.

• Pinching back dahlias when they are around 12 inches tall or have 6 sets of true leaves, that can promote bushier growth and more flower production.

In colder regions, dahlias need to be lifted and stored during winter. Dig up the tubers after the foliage has withered and store them in a cool, dry place. I use my cold cellar where temperature is generally above 5 degree Celsius, but if during some harsh winter days if temperature drops the I use a heating fan and monitor the temperature using digital thermostat
