Water: Adapted to cool, moist alpine meadows, mountain dandelion thrives with weekly watering for optimal health. It tolerates brief dry spells due to its efficient water storage and robust root system, which helps it maximize water uptake during variable rainfall in its outdoor environment.

Fertilize: Fertilize mountain dandelion sparingly with balanced formulas or high nitrogen options every 4-6 weeks during the growing season. Avoid overfertilization to prevent root burn, adjusting feeding based on plant cues. Use a diluted solution, especially for young plants, to promote vigor and flowering.

Pruning: Mountain dandelion, with its daisy-like flowers and rosette growth, should be pruned from early to late spring. Removing spent flowers and leggy stems enhances air circulation, promotes healthy growth, and maintains shape, reducing disease risk and ensuring a more vigorous plant.

Propagation: Mountain dandelion thrives in challenging mountainous environments and is best propagated by sowing fresh seeds in well-draining soil. Lightly press the seeds to ensure exposure to sunlight for germination. Maintain even moisture without waterlogging for successful seedling growth.
