DETAILS

Care Instructions
Carolina Larkspur thrives in temperate climates with moderate temperatures. It prefers bright, direct sunlight and should be watered when the soil is almost completely dry. The plant enjoys moderate humidity and should be protected from extreme cold.
Soil
Delphinium carolinianum prefers well-draining loamy soil. It is important to ensure that the soil does not retain too much moisture, as this can lead to root rot. A slightly acidic to neutral pH is ideal.
Fertilizer
A balanced fertilizer with an N-P-K ratio of 10-10-10 is suitable for this plant. Fertilize during the growing season to promote healthy growth and flowering.
Repotting
Repotting is generally not necessary for this outdoor perennial, but if grown in containers, repot every 2-3 years to refresh the soil and provide more space for root growth.
Propagation
Delphinium carolinianum can be propagated by seeds or division. Seeds should be sown in the fall or early spring, while division is best done in the spring when new growth begins.
Pruning
Pruning is required to remove spent flower spikes and encourage new blooms. Cut back the flower stalks after they have finished blooming to maintain the plant's appearance and health.
Toxicity
All parts of Delphinium carolinianum are toxic if ingested, particularly to pets and humans. Symptoms of poisoning include nausea, vomiting, and abdominal pain. Handle with care and keep away from children and pets.
Additional
Delphinium carolinianum is a beautiful addition to any garden, attracting pollinators such as bees and butterflies. It is important to provide support for the tall flower spikes to prevent them from toppling over in strong winds.
