Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Asarum tamaense prefers consistently moist soil but dislikes waterlogged conditions. Water thoroughly when the top 2-3 cm of soil feels dry to the touch.
Reduce watering slightly during the winter dormancy period, but do not allow the soil to dry out completely. Ensure good drainage to prevent root rot.
Pruning is generally not required for Asarum tamaense, as it maintains a naturally compact and attractive form. Remove any dead or damaged leaves or stems as they appear to maintain a tidy appearance.
This can be done at any time of year using clean, sharp scissors or pruning shears.
Propagation is best achieved through division of established clumps during the spring or early autumn.
Carefully dig up the plant and gently separate the rhizomes, ensuring each division has roots and at least one growth bud. Replant immediately in well-draining soil.
Asarum tamaense is a slow-growing plant and does not require frequent repotting. Repot only when the plant becomes root-bound, typically every 2-3 years.
Choose a pot that is only slightly larger than the current one, and repot in spring using a well-draining, organic-rich potting mix.
