watering

Lyall's Angelica needs to be watered once a week, in the spring and summer months, and every 2-3 weeks during the fall and winter months. Make sure to water only when the soil is dry to the touch and avoid standing water in the soil. Too much water can lead to root rot if the soil can’t drain. Provide Lyall's Angelica with a generous amount of water when you do water, moistening the soil to a depth of 6 to 8 inches.

sunlight

Lyall's Angelica (Angelica arguta) requires full sun to partial shade, with at least 6 hours of direct sunlight each day. Plant your Lyall's Angelica in a location that gets plenty of sunlight in the morning and some shade in the afternoon to protect the plant from the hot summer sun. They need the sunlight to photosynthesize and create food for their growth. Light shade can be tolerated, but the plant should not be shaded for long periods of time. With these conditions met, Lyall's Angelica will thrive throughout the growing season.

pruning

Prune Lyall's Angelica (Angelica arguta) in the late winter or early spring prior to new growth. Remove dead, damaged and diseased branches, then make sure to thin out any overcrowded branches. Prune up to 1-third of the plant to keep it a healthy size and shape. Cut back any long, or rogue branches to keep it tidy. Since Lyall's Angelica is an attractive plant you can prune it with a shearing technique to keep it looking compact and attractive.
