Mabon is also known as the Autumn Equinox and is considered a vernal equinox where the hours of day and night is roughly equal in number. It is the second harvest festival in the wheel of the year seasonal calendar (in the wiccan and Celtic pagan traditions).
I like to work with Demeter during Mabon time and make her offerings of wine, grapes, bread, corn, nuts and apples. I tend to use seasonal fruit and veggies as during this time they are in abundance.
Traditionally I like to perform a ritual to Demeter for the Autumn Equinox. Offerings of apples/pomegranates cut in half, wine, ears of corn and poppies on her shrine are made, as in the Greek pantheon she is the mother goddess of the harvest and the land.
I also like to bless seeds in her name which I plant during this time of the year such as: lavender, marigold, cornflower, larkspur, burdock, spearmint, fox glove, borage, calendula, chamomile, coriander, sorrel, parsley, poppy, onion, thyme, chives, rosemary, peppermint, catnip, caraway, soapwort, wormwood, pennyroyal, hyssop, queen anne’s lace, chicory, marshmallow, nasturtium and dill.
Here is a hymn I wrote which you can use for Demeter during the Autumnal Equinox:
Hymn to Demeter at the Harvest
Goddess of the Bounty, Harvest and Grains,
Give us what we need to gather our gains.
Madam of Marriage and the Sacred Law,
Hope giver to followers of your mysterious awe.
Barley, Corn and Poppy Mother,
Giver of food and abundance of Gaia.
Dominatrix of the cycle of life and death,
We pray for our bounty to be full of life’s breath.
Motherly matron of food and blessings unbound,
Turn the earth, sow our seeds to harvest plough.
Giver of boons, fertile and quaff,
Separate the wheat from the chaff.
Great divine feminine light upon the earth,
I adore and honor you with mirth.
