I don’t know how many times I’ve seen the suggestion that if you don’t have a garden, you can always grow some herbs on your windowsill. It reflects a lack of experience of life without gardens, and I think this is advice Pagans need to stop offering other Pagans about how to be greener.
Not all living spaces have windowsills. Boats don’t, caravans and static caravans don’t. Not all flats do, either. I have a friend who has no windowsills in her flat. Having a windowsill also doesn’t mean you have enough light to grow herbs. You might be able to grow ferns because those are shade-dwellers.
You have to get the plants from somewhere. If you’re the sort of person who doesn’t have a garden, you may also not have a car. Plants on the bus or taken for long walks are not reliably happy plants. Garden centres tend not to be in urban areas, so you may be limited to the things in pots you can get from supermarkets. Supermarket herbs in pots die.
Not having a garden can also be connected to poverty. You may not be able to afford plants. You may only be able to grow plants if other people give you plants. No one should be shamed for this.
Let’s imagine that you’ve got a flat, and you manage to grow plants in pots. After a while, the plants get bigger, and need potting up. You need soil to pot up a plant. You may have a nice friend with a garden and be able to move a little soil about. You may not. If you buy soil, it tends to come in large bags – larger than you need, larger than you may be able to store if you live in a small space. You might not be able to store pots, either. Of course you could buy plants and throw them away when they get difficult, but that’s not a very green solution.
Where are you going to pot up your plant? You may not have any safe outside space you can use, which leaves the choice of doing it in the kitchen or bathroom. If you’re renting, you cannot afford to mess up a carpet. Kitchens and bathrooms aren’t really designed for indoor gardeners, it is doable, but the smaller your space, the more awkward it all is. The less mobile you are, the less feasible it is. These are jobs that take both hands, and bags of soil are heavy. Not everyone can do it. As an indoor gardener, you won’t have gardening tools either. Yes, a lot can be done with spoons and knives from the kitchen, but if you’re worried about contaminating eating utensils, you might not want to go for that. And no, a set put aside may not be viable, because there may not be enough room even for that.
If the plant dies, what are you going to do with the remains, the pot and the soil? Disposing of a dead plant is part of its environmental impact. If you can’t do this well, then the green advantages of having it in the first place are questionable.
Yes, it is lovely to have houseplants and a garden, but if a person says they can’t do that, take them at their word and don’t make them feel awkward about it.
