Tricyrtis Plant Care:
Prefers a moist to wet, well-drained, slightly acidic soil in partial shade. Seldom needs division, but can be done in spring. Cut back by 1/2 in early June to control height and freshen foliage if needed. May benefit from extra watering during summer heat. Can cut down foliage after killing frost. Will colonize over time. Divide every 3-4 years in spring.
