watering

For Larkspur, water the soil deeply when it is dry to the touch, but don't let it become overly saturated. Depending on your type of soil, this could mean watering the plant approximately twice a week during the spring and summer months and once per week in the fall. During particularly hot and dry spells, the plant may require more frequent watering. In the winter months, allow the soil to dry out before determining if and when to water it.

sunlight

Larkspur (Delphinium (Pacific Hybrids)) thrive with 6-8 hours of direct sunlight per day. They should be provided with full sun during the peak of the day when sunlight is the strongest. Morning and evening sun is beneficial for larkspur, but they should be protected from intense midday sun and from the wind. When the weather is hot and dry, larkspur plants should be provided with a bit of shade to keep the roots cool and the plant healthy.

pruning

Pruning Larkspur (Delphinium (Pacific Hybrids)) should be done during Fall. This is the best time to reduce the size of the plant and to remove weak stems. Prune all shoots back to within 9 inches of the ground and remove any dead or broken stems. Pruning should also be done in late winter (February) to remove any excess growth from the previous year. Pruning should be done sparingly as Larkspur stems are delicate and can be easily damaged if pruned too much.
