I use washable cloth pads* ~ which I soak in water and then feed to the plants in the garden. I also use a Mooncup, which allows for a richer concentration and can be used in ritual, as paint, facemasks, food… etc. This deserves another post…
For now, I talk about feeding the plants.
Menstrual blood is highly nutritious. And although you may not feel inspired to take a sip from your mooncup, your plants will love you for it.
Especially roses. Look at the roses growing in my garden. Just a small plant earlier this year ~ now abundant with gorgeous red flowers, more buds appearing all the time… clear evidence they LOVE it! (apparently tomatoes love it too).
Dilute your blood with water first ~ to ensure absorption and not to overbear the plant as it is very rich.
