How to grow Delphiniums:

Delphinium grows well in cooler summers. Grow them in the sun. They need about a half-day of sunlight. Plant them in rich, fertile moist soil that is well-drained. Shelter it from strong wind. Space them for good air circulation.

Delphinium requires regular watering special if the summers are dry. Fertilizers help get better results. Stake the flowers as they can get heavy when they flower. Cut them back to the ground when the frost starts. Divide the plants every few years.

Delphinium is easy to grow from seeds. Plant the seeds in July. Then plant them outside in October for bloom in late spring and in summer next year. Delphinium creates a beautiful splash of color against a wall. It is also an excellent border plant. It ranges in color from white, yellow, purples, but it is best known for the blue variety. They use flowers to make blue ink.

About Online Flower Garden & Dino

I am a flower enthusiast and a gardener at heart. Ever since childhood I loved reading about plants and started gardening at an early age. First by helping my father in the garden and later managing a large garden myself in my teen years. I planted and cared for a large number of plants, flowers, and trees both outdoors and in a greenhouse. To this day I enjoy visiting gardens and parks and learning about new and old specimens and varieties of plants.
