With all the recent discussions about microplastics, I'm trying to transition to plastic-free options for my gardening. I usually grow in two raised beds, but I'm also looking to start using containers. I have some terracotta pots for herbs, and I don't mind if the containers are not super durable. For instance, I'm okay with using cardboard seed trays for my spinach since I sow it repeatedly. I'm curious if anyone has ideas or experiences to share about keeping gardening containers plastic-free?

If you're feeling crafty, you could always build your own containers from wood! I made one for my fig tree, and it's really functional. Just make sure it's sturdy enough to hold up for a while. It's a cool way to avoid plastic altogether.
I totally get your struggle; it feels like plastic is everywhere in gardening these days. For starting seeds, you can make soil blocks, which are a great zero-plastic option. And when it comes time to transplant, I recommend going with wood or terracotta containers. Just remember, being super strict about avoiding microplastics in your garden won't completely shield you from them, so if you have to use some plastic, go for sturdy, reusable choices!
Fabric grow bags are often recommended, but just a heads up—many of them are made from plastic. If you're looking for truly non-plastic options, consider using clay, stone, or even plaster containers. They may not last forever, but they won't release microplastics into the soil. Reusable options like heavy-duty seed trays made from recycled materials can also help reduce waste, even if they are still technically plastic.
That's a good point! I’ve also tried biodegradable pots like cow pots, made from manure. They break down over time and are helpful for starting seeds. Just be careful with terracotta; while it's a nice choice, it can dry out quickly.
That sounds awesome! I've been meaning to try my hand at wood planters. Do you have any tips for what wood to use or how to treat it to make it last longer?
