WaterLarkspurs should be watered deeply once a week, providing about 1 inch of water each time, which equates approximately to 0.623 gallons per square foot of soil. It's crucial to avoid overhead watering to prevent fungal diseases; therefore, water directly at the base of the plant. During hot, dry spells, you may need to water twice a week, but always check the soil moisture first; larkspurs prefer consistently moist soil but do not tolerate waterlogging. In the cooler seasons, reduce watering frequency as the plant requires less moisture due to slower growth and cooler temperatures.
LightLarkspurs thrive best in full sunlight conditions, requiring at least 6 to 8 hours of direct sunlight daily. The best spot for a larkspur would be an area where it can receive ample morning sunlight and partial shade in the late afternoon to protect from scorching in the peak of summer heat. If grown in too much shade, the larkspur will grow leggy and produce fewer blooms.
TemperatureLarkspurs prefer cooler climates and can generally withstand temperatures as low as 40 degrees Fahrenheit. They have a maximum temperature threshold of around 85 degrees Fahrenheit before they start to show signs of stress. The ideal temperature range for larkspurs is between 50 to 75 degrees Fahrenheit, where they will flourish and produce the most vibrant flowers.
PruningLarkspurs benefit from pruning to encourage branching and more blooms. Deadhead spent flowers regularly to promote continuous blooming throughout the season. After the first flush of blooms, cut the flower stalks back by one-third to encourage a second bloom. The best time for more aggressive pruning or cutting back can be in late winter or early spring, just as new growth begins.
CleaningAs needed
SoilLarkspur 'Fenella' thrives in well-draining, fertile soil with a pH of 6.5 to 7.5. A mixture of loam, organic compost, and a bit of sand to improve drainage makes the best soil mix for Larkspur.
RepottingLarkspurs, such as the 'Fenella' variety, typically do not require frequent repotting. They can remain in the same container for a couple of seasons if not outgrowing the pot or showing signs of stress.
Humidity & MistingLarkspur 'Fenella' prefers moderate humidity levels. It is typically outdoor-grown so ambient humidity should be sufficient; however, avoid overly humid conditions as they can promote fungal diseases.

Life cycleThe Delphinium 'Fenella', commonly known as Larkspur, begins its life as a seed that, given the right conditions, will germinate and develop into a young seedling. The seedling grows into a vegetative plant, producing a rosette of basal leaves and a central stalk from which lateral branches and deeply lobed foliage emerge. As the plant matures, it enters the flowering stage, producing tall spikes adorned with intricate, vibrantly colored flowers, which attract pollinators for reproduction. After pollination, flowers give way to seed pods that mature, dry out, and release seeds for the next generation. If environmental conditions aren't conducive for seed germination or if the cultivar is sterile, the plant may continue to grow and may require division to propagate. During the colder months, Delphinium 'Fenella' enters a period of dormancy where growth ceases until favorable conditions return in the spring.
PropogationPropogation time
Spring-Early Summer
The Delphinium 'Fenella', commonly known as Larkspur, is most effectively propagated through division, a practice best carried out in the early spring as the new shoots are emerging. This not only rejuvenates older clumps that may have become woody and less vigorous but also provides an opportunity to create new plants. To divide, carefully dig up the entire clump and gently separate the plant into smaller sections, ensuring that each division has a portion of the root system along with some shoots. These divisions should then be planted immediately into well-prepared soil, allowing enough space for the mature size of the plant. Keeping the soil consistently moist but well-draining will help the new divisions establish.
