How to Grow Cowbells and other Uvularia Plants in the Garden

If you are planning to grow cowbells (Uvularia plants) from seed then start outdoors at the end of summer from fresh seed.

Seeds should be sown into flats and lightly covered once sown. Sink the flats into a shady area and cover with glass; keep soil moist.

The germination time of Uvularia ranges from one to six months. Once strong enough transplant the cowbell to their final location at the end of spring.

Ideally Uvularia should be spaced from 15 to 30 cm (6 to 12 inches) apart (dependent upon the size of species).

Cowbells prefer to grow in shady or partially shaded areas of the garden that have a rich and acidic woodland soil (pH 5 to 6) which is moist.

Caring for Uvularia

Plants of the Uvularia genus such as cowbells, Wood daffodils and Merry bells are easy to look after. They like a moist soil so keep well watered.

Being a woodland plant they like shade, especially their roots, so ensure that cowbells always have a good mulch of leaf mold. If you require more plants then propagate cowbells by division in the spring.
