Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water consistently when the top 2-3 cm of soil feels dry. Avoid waterlogging, as Alpine Pennycress prefers well-drained conditions.
Reduce watering frequency during winter dormancy, allowing the soil to dry out more between waterings to prevent root rot.
Pruning is typically minimal. Deadhead spent flowers to encourage more blooms and maintain a tidy appearance. If the plant becomes leggy, light trimming can be done in early spring to promote bushier growth.
Remove any dead or damaged foliage as needed.
Alpine Pennycress can be propagated by seeds sown in early spring or fall. It also readily self-seeds in suitable conditions. Division of established clumps in spring is another effective method.
Ensure new plants are given excellent drainage.
Repotting is generally not necessary for Alpine Pennycress as it prefers to be slightly pot-bound.
If grown in a container and it outgrows its pot, repot in spring into a slightly larger container with fresh, well-draining potting mix. Ensure the new pot has drainage holes.
