Choose Dahlia Varieties

Ensure your dahlias receive at least 6-8 hours of direct sunlight daily for optimal growth and blooming.

Amend the soil with organic matter, like compost, to improve drainage and fertility. Dahlias thrive in well-draining, nutrient-rich soil.

Prepare the Soil

Plant dahlia tubers with the “eye” or growing point facing up and buried about 6-8 inches deep, ensuring proper root development.

Planting Depth

Keep the soil consistently moist, but avoid overwatering. Water deeply when the top inch of soil feels dry to the touch.

Watering Needs

Provide support for tall dahlia varieties using stakes, netting, or the corral method. This prevents stems from bending or breaking and ensures upright growth.

Supporting Stems

Regularly deadhead spent blooms to encourage continuous flowering. Remove faded flowers just above a leaf node to redirect energy for new growth.

Deadheading Flowers

Feed your dahlias with a balanced fertilizer. Apply a slow-release granular fertilizer or liquid fertilizer every 4-6 weeks for healthy growth.

Fertilize Regularly

Monitor for pests like aphids and slugs. Use organic pest control methods and practice good garden hygiene to prevent common dahlia diseases.
