Care Guide
Watering
When it comes to watering delphiniums (Delphinium elatum), it's important to make sure the soil is slightly moist but not soggy. Water the plants deeply when the soil begins to feel dry to the touch. It is typically best to water in the cooler parts of the day, such as early morning or late evening, to reduce evaporation from the sun's heat. During periods of extreme heat, water the plants every other day to ensure they remain hydrated. In winter months, reduce watering as the plants are dormant and don't require as much water.
Light
Delphiniums should be given full sun or partial shade to thrive. Ideally, your delphinium should receive at least 6 hours of direct sunlight each day. If your delphinium is planted in partial shade, it should still receive 4 hours of direct sunlight each day. Morning sun is best for this species of plant, as prolonged direct afternoon sunlight can impact delphiniums negatively.

Pruning
Delphinium elatum should be pruned once a year in mid to late spring after the last frost. To ensure that the plant has the best chance of flowering in the upcoming season, cut the stems back to 1/4 to 1/2 their original height. Alternatively, the old stems can be completely removed when new growth appears, or removed in the autumn. As the stems are quite brittle and easily snap off at the joint, it is best to use a sharp pair of scissors or pruning shears when pruning. It is also a good idea to wear gloves to protect the hands from its sharp leaves.
