Altar
If you have any antlers, the Buck Moon is a good time to incorporate them on your altar. Deer shed their antlers. If you live in an area with a strong deer population, you may be able to find them in the woods. You can always buy them (in among dog treats) but I have no idea if deer are killed to get these.
The days may be getting shorter, but there are still more than 12 hours of sunlight per day. It’s summer and sunny, so you can re-use other items from your Litha altar or add new ones. If you have an outdoor altar, you can put out honey cakes or seed cakes for the birds or create a new space just for birds and insects (so no birds poop on your altar). Any summer ritual is a good time to honor bees. Without pollinators, most plants could not survive. You can add a bee watering station to your bird area or set up a bee altar somewhere else. If anyone in your household is allergic to bee stings, put your bee altar far away from areas people frequent. A bee watering station is essentially a shallow dish holding marbles or rocks and water. They are sold commercially but it’s easy to make your own and I think the bees will appreciate your effort. Bees also like hummingbird feeders.
Ritual
For Summer rituals, I re-use items and ideas from Litha (mid-summer). I especially like the idea of drawing down the sun on the long summer days and honoring the god in all his forms. During any Summer rituals you can also charge your sun water or sun-powered spells or charms. Water your plants with intention. Decorate with citrus. Incorporate with things that mean Summer to you. I always associate Summer with the scent of coconut, I think because of the old fashioned Coppertone sunscreen I used as a kid, so I use coconut scented candles and essential oil. Personally, I don’t like pina coladas, but I’m sure there’s a way to fit them into a ritual. Maybe I’ll think up a good hurricane ritual (with a drink, not a weather event).
