Growing and Maintenance Tips

Alchemilla mollis is an easy care perennial that adapts to a wide range of soil conditions except wet sites. It does perform well in clay. It is not drought tolerant and needs to be watered in periods of drought. After flowering a light shearing will freshen up the plant and promote new growth. It dies to the ground completely in the winter so old leaves should be sheared to crown level in the spring. It will grow in full sun but the foliage will look best where there is some protection from the hot afternoon sun.
