Sunlight Requirements Dahlias require 6-8 hours of full sun a day and are sensitive to frost. For best results, cover during the hottest part of the day to prevent wilting/scorching.

Watering your Dahlias Wait to water newly planted tubers until after you see the first green shoots coming up through the ground.

Fertilizing When fertilizing dahlias, use a balanced fertilizer that provides the necessary nutrients for the plant. Apply every 4-6 weeks after the plants are about 6 inches tall.

Benefits of Pinching Pinching encourages bushier plants, as well as increasing flower production and overall stem length.

The best time to cut dahlias is in the early morning before the heat of the day to keep them from shock and wilting - it’s important to pick them almost fully open but not overly ripe.
