Growth Rate

Given its rapid growth rate during spring, the bulbous bittercress swiftly develops structures like leaves, buds, and stems. With the burst of spring temperatures, energy stored in the bulbs results in a spurt of growth. This intensive growth reflects in a rapid increase in height and luxuriously filled foliage. Additionally, the swift development facilitates the timely formation of white, cruciform flowers that bloom in clusters. While its growth rate might simmer down in other seasons, its quick spring growth ensures a successful lifecycle.

Water: Bulbous bittercress thrives in moist woodland conditions with consistently damp but not waterlogged soil. It requires weekly watering to maintain stable moisture, making it more suitable for outdoor cultivation. Adequate water uptake during the growing season is essential for its lush foliage and vibrant flowering.

Fertilize: For bulbous bittercress, use a balanced fertilizer bi-monthly during growth, reducing frequency in dormancy. Avoid over-fertilization by using a light hand. Seasonal adjustments maximize vitality, with slow-release granules recommended. Water bulbous bittercress before fertilizing to minimize root shock.

Pruning: Bulbous bittercress is a perennial herb with delicate white flowers, thriving in wet habitats. Prune in early spring to manage shape, cut back older stems, and remove damaged foliage. Good air circulation prevents mildew, enhancing growth and flowering. Proper care facilitates natural water filtration.

Propagation: Bulbous bittercress can be easily propagated through division, ensuring genetic consistency. Separate the root ball while preserving root structure, then repot or plant at the same depth. Water generously to promote establishment in the new location, allowing for rapid expansion or sharing.
