Dahlias are relatively sturdy plants if grown in the right lighting, heat, and soil. Care of dahlia flowers may vary dependent upon your zone, but here are a few dahlia growing tips to help you get maximum blooms and healthy, bushy plants.

Dahlias need to be kept weed free. Use organic mulch around the plants to prevent weeds and conserve moisture

Provide plenty of water to your plants. Water plants deeply once or twice per week. Big dahlias need a support structure to keep the heavy blooms from bending to the ground. Fertilize monthly with water soluble fertilizer or twice during the growing season use ½ cup (240 mL.) 5-10-10 scattered around the root zone of the plants.
