According to the information we found, there are different Wicca sects, and each one has it’s own funeral traditions. In most cases, the specifics of the funeral will depend on the preferences of the family, and often the actual ceremony will look like a traditional funeral. There don’t appear to be any hard and fast rules, but these types of funerals are often simple and focused on nature or the elements.
There is quite a lot of information available on the Internet that goes into more detail on the practices of this particular community. Here’s an example:
I’m sorry we can’t be more specific. There are many different ways that funerals are done and since Wicca is uncommon, we don’t have any particular expertise in their traditions.
