Like most other viburnums, squashberry propagates most easily from cuttings or layering. Layer long side shoots in the fall and sever the rooted branches a year later in September. Take softwood cuttings in June or July and hardwood cuttings in September. Raising squashberry from seed is challenging. Sow seeds as soon as they are ripe and leave them.
Germination occurs irregularly and takes a year and a half or more.
In our coastal gardens use squashberry in deciduous to evergreen woodland settings or mixed among other shrubs. Viburnums are arranged in clusters for best display. The bright red fruits will attract many birds. Squashberry was widely eaten by BC First Peoples. The Thompson of the southern interior enjoyed the sour fruit from the bush or dried it for storage.
