watering

Small-flowered leaf cup (Polymnia canadensis) is a sun-loving plant that thrives in moist, well-drained soils; it prefers the soil to be slightly acidic. It is best to water this species deeply and infrequently, allowing the soil to dry out in between waterings. Water deeply (2-3 inches) in early morning once a week, or every other week during very hot, dry weather or during periods of drought. It is important to avoid over-watering; this could lead to root rotting or other issues. Make sure to avoid wetting the foliage, as this could cause fungal problems.

sunlight

Small-flowered Leaf Cup (Polymnia canadensis) prefers full sun to part shade. It can tolerate short periods of shade, but it thrives best in a location that receives at least 6 or more hours of direct sunlight each day, preferably in the morning. It does best in slightly acidic soil and prefers moist soil. Too much direct sunlight in the late afternoon may cause the plant to become stressed, especially during the heat of summer.

pruning

For optimal health and growth, small-flowered leaf cups should be pruned in late winter or early spring. Minor pruning can also be done in early fall to shape the plant or control growth. When pruning, it is important to remove dead, diseased, or weak branches, as well as any that have crossed and are rubbing against each other. Remove no more than 1-third of the stems at any time, as over-pruning can shock the plant and slow growth. Additionally, prune branches back to just above a healthy bud or branching to encourage new growth.
