Gardening is probably the single most soothing thing I do - living in the city I’m restricted to my balcony when growing outdoors, but that balcony is a jungle of tomatoes, peppers, herbs, and wildplants. I like to smoke out there right after watering - the smell of the wet earth and plants is so calming. It’s also much less work watering a dozen plants - in times when I’ve had a larger garden, watering has been a much less magical, more tedious responsibility.
I live in a city as well and have a communal space here where I keep a bunch of similar stuff. While I am not allowed to smoke in that area going down in the morning and evening to water and just check on their growth is often the most rewarding part of my day.
