How to keep Delphinium Glaucum.
Light
Sierra Larkspur thrives under plentiful sunlight. Its native habitat is mainly places that receive unfiltered sunlight. This exposure supports vigorous growth. However, too much light can cause wilting, while too little light can stunt growth and reduce vitality.
Temperature
Sierra Larkspur originates from habitats with temperatures ranging from 32 to 90 °F (0 to 32 ℃). This plant favors cooler conditions and may need measures like providing shade or extra watering during excessively hot seasons.
Fertilizer
The best time to fertilize a Sierra Larkspur is in early spring, as it emerges from dormancy and begins active growth. Fertilizing supplies essential nutrients for healthy development. Although Sierra Larkspur has fairly low fertilizer requirements, an annual application can improve its survival and encourage better, longer-lasting blooms.
