Trillium grandiflorum f. polymerum 'Flore Pleno'

🌱Spring

• Spring - late · Outdoors

  Feed with slow release fertiliser

  Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

  This is a simple way to provide a nutrient boost as a single annual procedure.

• Spring-Autumn · Outdoors

  Water to keep the soil moist

  For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.

  Without regular watering some plants never fully regain their beauty.

• Spring · Planting

  Divide after flowering

  After flowering divide the rhizomes, this needs to be done with care as each part of the rhizome must have a growing bud point or it will fail. Dust the cut surface with fungicide before replanting.

  Identifying a bud point: each rhizome has a large shoot at its growing point. Behind these are a number of small pointed buds that stick out between the rhizome's scales, pointing upwards.
