How to Plant Trillium Perennials
- 1). Purchase nursery-grown plants that have not been collected from the wild. Locally propagated and raised plants have a better chance establishing themselves after transplanting than plants that originated from outside the area or were collected from nature.

Find the correct location for the trillium plants. Trilliums like deep to mottled shade in woodland areas. The soil needs to drain well but has to stay slightly moist with a lot of composted organic material mixed in. The acidity should be neutral to slightly acidic. Be sure to choose a space away from foot traffic and that will not be disturbed. Trilliums do not like to be transplanted once established, so plan for the long term. They do best when their woodland habitat near streams and in low-lying areas is simulated. - 3). Dig a hole a few inches deeper and wider than the pot the trillium came in.
- 4). Build a small mound of soil in the middle of the hole a few inches high.
- 5). Remove the trillium from the nursery pot and gently loosen the soil around the sides and bottom of the root ball. Be careful to not damage the roots.
- 6). Place the plant in the hole on top of the mound of soil and position it so that it stands upright and the stem of the plant will meet the ground surface at the same level it was in the pot. You may have to add or remove soil on the mound to raise or lower the level of the plant in the hole.
- 7). Fill in the soil around the trillium and gently firm it with your hand so that the plant stays in place.
- 8). Water the plant thoroughly and let it soak into the ground. This may create small pits in the soil surface as the water settles the soil. Fill these with more soil and water it in until the surface is level.
- 9). Monitor the trillium closely for the first couple of seasons while it is establishing itself. Be sure to keep the soil evenly moist, especially in the hot summer months. Once established, trilliums need little to no care unless you are in a warm summer climate in which case they may need additional water.
