If you actually have a farm and use a real plough, it's traditional to bless the plough right before using it. The date that one would begin using one's plough would be different in different locations.
Most pagan and heathen groups that celebrate Charming of the Plough on a specific date don't actually use a real plough for anything. Some American Asatru groups celebrate Charming of the Plough on the second day after Twelfth Night, which is January 3rd. Some celebrate it on February 2nd, which is otherwise called Candlemas / Groundhog Day / Imbolc / Imbolg / Brigid's Day.
My practice of honoring the First Woman started with a weed. A weed is a plant growing where one doesn't want it.
In June of 2016, I found a four foot tall plant in my tomato bed. Online friends on the Plant Identification group helped me positively identify it as a Siberian Elm, which is not the same species as the American Elm. Siberian Elm is an invasive non-native species, so it had to go. But, it was an elm. Elm is the tree the threefold Odin made the first woman from. Embla was her name, and was also the word for elm. I was unlikely to have an elm sapling again, so I had to make good use of it. I pulled it up roots and all and whittled it into an Embla doll with my pocket knife.
Planning a ritual, I was thinking about what sort of drink to offer to specific gods, and listening inwardly to see if my plans were acceptable. Freya said she wanted rose.
I had gotten into the habit of smelling the pink rose in the front yard for Freya. It's an antique breed with a wonderful scent. I clarified: Did she want more of that? Yes, that rose. To cut the flowers and bring them inside? No. To eat.
The Sif doll seated on the harvested wheat. This is a Lithuanian doll that I bought in an amber shop along with some amber in 1989. Shortly after I dedicated part of my garden to Sif last year, I was walking past the display of folk art in my house where I used to display this doll and it called to me to dedicate it to Sif. So I did a dedication ritual, which I related in my post A Doll for Sif. I moved the doll to my Spiritual Souvenir display, which is kind of a wall altar.
I almost always make, remake, or repurpose things to dedicate rather than buying things new for that purpose. I feel that conserving resources is part of how I live as a heathen.
The Wheel of the Year is different for me than it was for the ancient Northern Europeans. I live in the Mojave Desert in southern Nevada. Part of respecting nature is respecting local conditions rather than trying to stick to what a book says should be because that's the way the ancestors did it.
Last December, as I related in my blog post Planting Heritage Wheat for Sif, I planted locally adapted arid-lands wheat in a small garden area dedicated to her. Here are my results. I harvested this wheat in early June.
I dedicated a small doll to the grain goddess, Sif, to keep in the Spiritual Souvenir Shrine on my wall. I had had the doll for years, having bought it in the Soviet Union when I was in college, but one day I suddenly looked at it and thought "Sif." It has pale yellow hair, but its hair was all messed up from the years, so I restyled it. While I was trying to smooth her hair down, some of it fell out!
I had to fix that somehow. So, of course then I had to make the hairstyle better than before, because in the myth where Loki cuts her hair and then goes and has the dwarves make her new hair, the renewed hair was better. So instead of retying the pony tails with the orange thread the doll came with, I retied it with gold thread. I completely unintentionally re-enacted the grain myth where her hair is cut and then replaced with hair of gold, symbolizing the harvest and regrowth of the grain. Now it's a Sif doll for sure!
